Definition and Concept Agro-Forestry

Agro forestry is an age-old practice of integrating farming with practices, preferably on the same unit of land on sustainable basis. Agro forestry systems have received increasing emphasis in the recent years because of their potential to yield fodder, fuel wood and small timber in addition of food. Shortage of fuel woods for construction and commercial purpose. Implementation of development activities like mining, quarrying and river valley projects are the other reason for deforestation. Shifting cultivation, which is practices in the North-Eastern zone of India, has also affected forest acreage.

Definition: The practices of including trees in crop or animal production agroecosystem. Agro forestry may be defined as an integrated self- sustained land management systems, which involves deliberate introduction / retention of woody components with agriculture crops including pasture / live stock, simultaneous or sequentially on the same unit land, meting the ecological and socio -economic needs of people. Or Agro forestry is a collective name of land use system and technologies where woody perennials are deliberately used form the same land management units as agricultural crops and or animals in the same form of spatial arrangement of temporal sequence. In agro-forestry systems, there is both ecological and economic interaction between different components.

Introduction

The word ‘Statistics’ is probably derived from the Latin word ‘status’ (means a political state) or the Italian word ‘statista’ or the German word ‘statistik’, each of which means a ‘political state’. It is used in singular as well as in plural sense. In singular sense, statistics is used as a subject that deals with the principles and methods employed in collection, presentation, analysis and interpretation of data. In plural sense, statistics is considered as numerical description of quantitative information.

Statistics (Definition), Scope and Limitations

Different persons defined Statistics in different ways. Some of the popular definitions of Statistics are given below.

According to Croxton and Cowden, “Statistics may be defined as the collection, presentation, analysis and interpretation of numerical data”.

According to Sir R.A. Fisher “The science of Statistics is essentially a branch of applied mathematics and may be regarded as mathematics applied to observational data”.

Fisher’s definition is most exact in the sense that it covers all aspects and fields of Statistics. On the basis of above ideas, Statistics can be defined as a science which deals with collection, presentation, analysis of data and interpretation of results.

Meaning, Concept & Definition of Education

1. “Education is the process of developing capabilities of the individuals so that they can adequately respond to their situations”.

2. The modern definition of Education- “It is the production of desirable changes in human behavior- in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them”.

3. Education is the process of giving training and instruction to people to develop their knowledge, abilities, skills, character and mental powers.

Knowledge: It includes-facts, concepts, principles and relationship.

For example: Extension worker educates a farmer on cultivation practices in sweet corn. (Things known)

Attitude: An attitude can be loosely defined as a feeling towards some object, person, and situation or idea. For Example

Extension worker changes the negative attitude of a women farmer and makes them adopt Mushroom cultivation. (things felt)

Skills: Ability to do things.

For example: Extension worker improves skills of a cotton farmer on stem application of pesticide (things done)

‘Importance of Agriculture in National Perspective in India

Importance of Agriculture in Indian Economy: The following points emphasize the importance of agriculture in Indian Economy. Indian is an agricultural country, where 70 per cent population is dependent on agriculture. This forms the main source of income. The contribution of agriculture in the national income in India is more, hence, it is said that agriculture in India is a backbone of Indian Economy. The importance of agriculture in the National Economy is explained by the following points.

Role of agriculture in Indian economy: Agriculture is the main sector of Indian economy which is amply powered by the following points:

Share in National Income: The contribution from agriculture has been continuously falling from 55.1% in 1950-51 to 37.6% in 1981-82 & further to 18.5% in 2006-07 and 14.2% in 2011-12 and now 13.1%. But agriculture still continues to be the main sector because it provides livelihood to a majority of the people. The share of the agricultural sector’s capital formation in GDP declined from 2.2% in the late 1999s to 1.9% at precent.

Introduction

The dairy sector is one of the most important food sectors, which introduced the physical, chemical, microbiological and sensorial criteria duringprocessing steps and in the final dairy products. Several agents/ingredients of non-dairy origin are commonly used to maintain the quality of milk and milk products during processing, transportation and storage. In general, such ingredients are known as food additives and it can be antioxidants, coloring agents, flavoring compounds, preservatives(naturals and synthetic),artificialsweeteners, vitamins, minerals, stabilizers, emulsifiers and curing agents. From the safety point of view, some toxic agents can come into contact of dairy products duringmilking, storage or processing; such as fungal toxins, heavy metals, antibiotics or radionuclide’s, etc., which need to be identified and processed accordingly. Although addition of food additives in food/dairy product is controlled under country specific food laws or Codex Alimentarius Commission (CAC), few dairyproducts such as butter and unflavored fermented milk products are highly restricted for food additives.

Introduction

Spectacular accomplishment in every sector has enabled India to be amongtop achieving nations. However, every section of the society is not benefited by these achievements and problem of malnutrition still remains unresolved. Malnutrition is a common problem faced by underdeveloped and developing countries suchas Philippines, Nepal, Sudan,Tanzaniaand Indiasincelongback. Malnutrition includes undernutrition(wasting,stunting,underweight),inadequate vitamins or minerals as well as overweight, obesity and resulting diet-related non communicable diseases(NCDs). As per the latest report of World Health Organization, 52 million children under 5 years of ageare wasted, 17 million are severely wasted and 155 million are stunted, while 41 million are overweight or obese (WHO, 2018). More than 50% women of marriage age are suffering from anemia. If women are malnourished at the time of pregnancyand delivery, the babybornface theproblems such asphysical retardation,sensitive tocommon infections, reduced cognitive abilities, reducedmental development, etc. As per the World Health Organization (WHO) guidelines, starting from the date of conceiving a child, the first 1000 days are a critical window from nutrition point ofview.Unfortunately, inseveral regions of developingcountries includingIndia, neither the mother nor the babyis provided with the right quantity and qualityof food during this window period. Therefore, it is important for the policymakers to identifymalnutrition at an earlystage for timelyplanningand implementation of various intervention strategies at the community, village, and district level. NitiAyog, Government of India (GoI) (previously known as Planning Commission), in an effort to eliminate malnutrition,regularlyplans several short and longtermnutritionalprogrammesand policies.In thischapter,we willdiscuss some of these policies launched since independence and their impact in combatingmalnutrition.

Introduction

There are manypeople all over the world who have a certain level of sensitivity or intolerance towards milk and milk products. The reactions to milk which involve the immune systemare termed as milkallergy, whereas, difficulty in the digestion of the milk and milk products is known as milk intolerance. Milk intolerance occurs due to malabsorption of milk sugar (lactose) in intestine, a condition in which lactose is not digested into its monomers (galactose and glucose) due to lower activity or insufficiency of lactase enzyme. Inability to digest lactose, which is a disaccharide present only in milk, is specifically known as lactose intolerance. However, hypersensitivity involves the adverse immune reaction(allergic reaction) inthe body causeddue to the ingestion of milk proteins. Milk and milk products are major source of basic as well as essential nutrients and cannot be skipped from the diet of the individual. It is a rich source of calcium,which is essential for the growth and reformationof bones. The decline in calcium may lead to thin, fragile bones that break easily, a condition called osteomalacia or osteoporosis in women. Thus, it is a matter of concern for both children andadults whoare allergic or intolerant towards milk and milk products and not getting enough calcium and other nutrients in diet. This chapter would provide more insight about milk intolerance and milk allergy/hypersensitivity and how to deal with it.

Introduction

Digestion may be defined as the hydrolytic process carried out by various enzymes for breaking down complex food components such as proteins, fats and carbohydrates into simpler molecules like amino acids, fatty acids and monosaccharides, respectively. Whereas, absorption may be defined as the movement ofthese simple soluble digested food componentsalongwithvitamins, minerals and water from gastrointestinal track into the circulatory system.

The process of digestion starts from oral cavity (mouth) and ends at large intestineincluding tongue, teeth, jaws,secretions from salivaryglands (parotids, sub maxillary or submandibular and sublingual glands), pharynx, esophagus, stomach, small intestine and digestive enzymes secreted from pancreas and liver.

Introduction

Nutritive value of any food indicates the calories content as well as quality attributes. Macronutrients such as carbohydrates, fats and proteins provide energy by4-9-4 rule. It meanstheyprovide 4,9 and 4 kcal/genergy, respectively, when oxidized completely. Though micronutrientssuch as vitaminsandminerals do not provide any calories, they are essential for the enzymatic activity and metabolic reactions.

ATP or energy is measured in terms of ‘calories’ or ‘joule’. One calorie is the amount of heat required by 1g of water to increase its temperature from 14.5 to 15.5°C under standard conditions. Nutritive value of any food can be measured on shelf usingcalorimeter, in which food is completelyoxidized under specified conditions and converted into CO₂ and water.

Introduction

Nutrition is the fundamental pillar of life and an essential foundation of human and national development. Rightfrom the earliest stage of human development, the fetal stage, at birth, infancy, childhood, adolescence, adulthood and old age, nutrition forms the basis for survival, performance, mental and physical development & economic and social development.Nutritional deficiencies during pregnancy, fetal and early postnatal life can have a negative impact not only on the subsequent growth and development but can also lead to changes in metabolic regulation and homeostasis.

Introduction

Nutrition, a basic human need, is a critical part of health and development. Nutrition can be defined as the intake of food, deliberated in relation to the body’s dietary needs. On one hand, good nutrition – an adequate, well balanced diet combined with regular physical activity – is a foundation of good health, whereas,poor nutritionleads toreducedproductivity,impairedmental andphysical development, increased susceptibility to disease, and reducedimmunity. According to WHO, under-nutrition, together with vitamin and mineral deficiencies accounts for one-third of all child deaths and impairs healthy development and lifelong productivity. At the same time, sedentary lifestyles, demographic shifts, urbanization and the liberalization of markets have steered the world population to being overweight along with risk of chronic diseases like hypertension, dyslipidemia, type 2 diabetes, coronaryheart disease, stroke, etc.; thus, resulting in a double burden of malnutrition.

To address this dual burden of malnutrition, individuals needaccess to sufficient and good quality food; but focussing solely on food security is unlikely to solve the problem of global malnutrition. The challenges of malnutrition cannot be solvedjustbyincreasingfoodproductioninordertoimprove healthand nutritional status of the population. To resolve such challenges, awareness about food choices for optimal health plays a pivotal role among population.

Human nutrition is the science of understanding food; its component; intake; and how it is related to health, growth, development and diseases. Human nutrition involves the study of ingestion, digestion, absorption and assimilation of the nutrients; their metabolic functions, deficiency or excess disease as well as their regulation through several factors such as choosing particular food components/nutraceuticals or physical activity.

Introduction

The basic physiological structures of mammary glands in all species are almost same and are located externally in order to fulfill the milk requirement of neonates after parturition. The process of secretion of milk from the mammary glands is known as lacto genesis. Milk provides an almost complete nutrition to neonates from birth till weaning period. It is a complex mixture of various constituents like:

Lipids such a striacyl glycerols(TAG),phospholipids,cholesterols and other sterols, free fatty acids and fat-soluble vitamins

Carbohydrates such as lactose, oligosaccharides

Proteins such a scaseins, α-lactalbumin, β-lactoglobulin, immunoglobulin’s, bovine serum albumin, lactoferrin, lysozyme, enzymes, hormones and growth factors

Non-protein nitrogenous compounds like urea, creatine, creatinine, uric acid and amino acids

Major and minor minerals, water-soluble vitamins and cells (leucocytes, macrophages, and epithelial cells).

Introduction

Proteins are the most abundant organic compounds constituting major part of the body. Chemically, proteins are nitrogen containing macromolecules and polymers of L α-amino acids, which serve a wide range of structural and biological functions in animal body. For example, connective tissue made up of collagen, metabolicenzymes, neuro transmitters,signal in gmolecules, structural components of cell membranes and cell organelles, etc. all are chemically proteins.

Before goinginto the details of protein metabolism, first, we need to understand that there are majorly two sources of proteins in our body: dietary protein and body protein. Dietary protein is taken in diet, while body protein indicates the protein and amino acids synthesized in animal body to fulfill the requirements for growth and development. The digestion of proteins will not be discussed here as it has been described in detail in chapter 12. Dietary protein is digested in presence of several enzymes such as trypsin, pepsin, chymotrypsin, aminopeptidases and carboxypeptidases and is converted into mono-, di- and oligopeptides in stomach and small intestine; and finally converted into amino acids. These amino acids are transported to the systemthrough intestinal mucosa via active transport, from where they enter into the cells for further metabolism. Therefore, ‘metabolismof proteins’ is more appropriatelylearnt as ‘metabolism of amino acids’.

Introduction

The diverse cluster of naturally occurring organic compounds including fats, oils, fatty acids, waxes, phospholipids, eicosanoids, terpenes, steroids and fat soluble vitamins that do not prefer to interact with water but soluble in non-polar organic solvents like ether, chloroform, benzene, acetone, are called as lipids. The main functions of lipids in biological system include storage and transport of metabolic fuel, structural component of cell membranes, insulation & protection of vital organs from shock and carrier of fat soluble vitamins. Contradictory to proteins,lipids are not polymers in nature and are hydrophobic due to presence of a long hydrophobic chain. Apart from this, lipids also act as precursor molecules for several pigments, hormones and signaling molecules.

Introduction

Carbohydrates are the most common source of energy for all living cells, which, in presence of light, are formed by the green plants from CO₂ and water during photosynthesis. It canbe said that ‘light’ is theultimatesourceof energyrequired for all livingcells.Glucose,a monosaccharide,plays a centralroleincarbohydrate metabolismin all plants, animals and manymicroorganisms. Glucose is derived from the polysaccharides (starch, glycogen) and non-carbohydrate sources (amino acids, glycerols, etc.) during metabolism and ultimately converted either into carbondioxide and water orotherintermediateproducts.Complete oxidation of glucose to CO₂ and water provides ~2,840 kJ/mol energy. The other monosaccharides such as fructose, galactose, mannose, etc. are also important molecules in carbohydrate metabolism.

Introduction

Hormones may be defined as specific chemical molecules produced in certain specific organs called specialized cells or endocrine glands. They are delivered into the blood stream or some other body fluid in minute amounts by the circulatory system of the body and their they exerts a physiological effect at a site of action remote from its origin, regulating numerous biological activities including growth, development, reproduction, water & electrolyte balance, storage & usage of energy etc.

Introduction

The basic components of diet include carbohydrate, protein, fat, vitamins and minerals. Vitamins are the essential nutrients which are not formed in our body and required in minute amount from the diet. Vitamins are crucial for the optimal functions of several enzymes; thus important for optimal growth and development. Vitamins perform various functions that help in regulation of metabolism, prevent chronic diseases, maintain natural appetite, mental health and immunity.

In 1912, Polish biochemist Kazimierz Funk coined the term ‘vitamine’;a substance that was present in rice polishing and foods that cured polyneuritis in birds and beriberi in humans. The name is from ‘vit’ for vital nutrient and ‘amine’ for its similarity as an amine. Vital signify that these factors are indispensable for life. Earlier they are identified and thought to contain amino groups, thus the word amine was used, which was true for thiamine but later work revealed that most of the vitamins do not have amino groups. Thus the word was shortened to vitamin in English. It should be noted that the term vitamin does not denote to some othern utrients such as essential amino acids, essential fatty acids, dietary minerals or other nutrients that contribute towards good health.

Vitamins may be defined as organic compound needed in minute amount through diet to perform specific biological functions for normal growth and health of the organisms.Vitamins should have following characteristics:

Introduction

The nucleic acids are the molecular depots that are responsible for continuity of life by transfer of hereditary information from one generation to next. The sequence of nitrogenous bases containing programmed instruction determines the structure of every cell constituent and eventually every protein. In 1869, Friedrich Miescher, Swiss chemist, isolated an unknown phosphate-rich substance from pus cells named as nuclein, which was quite different from other organic substances like carbohydrate, protein, and fat. Altmann in 1899 ascertained that the nuclein also had some acidic characteristics and changed its name to ‘nucleic acid’. Later, nucleic acid was also isolated from salmon sperm nuclei as DNA-protaminecomplex. In 1953, James D.Watson and Francis H.C. Crick constructed the model of three-dimensional double helix structure of the DNA molecule which could successfully explain DNA replication.

Introduction

Billions of chemical reactions are happening inside human body and that too with lightning speed. However, the same reactions if carried out in laboratory, they take a very long time. The reasons behind it are the biocatalysts, also known as enzymes, which are synthesized by living cells. Chemically, they are proteins(except ribonucleic acids: RNA), colloidal in nature, thermo-labile in character and very specific in their action. For example, hydrolysis of proteins by a strong acid at 100°C takes a couple of days; but same proteins can be digested within couple of hours inside human body at 37°C. Similarly, carbonic anhydrase is used as a catalyst by living cells to transfer carbon-di-oxide from cells to blood. This process is 107 times quicker than the same process if occurs without the help of enzymes. Therefore, enzymes can be defined as the biomolecules or biocatalysts which can speed up the rate of the chemical reactions. The substance upon which an enzyme acts is called as substrate and the one which is produced as the result of enzyme-substrate reaction is known as product.

Sea Buckthorn (Hippophae sp. ), a high altitudinal, thorny, temperate, deciduous, dioecious, actinorhizal shrub or small tree belonging to the Kingdom-Plantae, Clades-Angiosperms, Eudicots and Rosids, Order- Rosales, Family-Elaeagnaceae and native to Eurasean Countries like India, China, Russia, Nepal, Pakistan, etc. (Barik et al., 2016). SBT is having tolerance towards a wide group of pests and insects, can grow in extreme nutrient deficient conditions and temperature range of -40 °C to 40 °C. It contains more than 190 reported invaluable phytochemicals and has the potential for multidimensional use as food, fodder, medicine, fuel, and conservation of soil and bio diversity (Qinxiao and Hongyan, 2003; Barik et al., 2016). SBT berries, leaves, stem and root barks also contain nutrients and bioactive compounds which mainly include lipids, sugars, amino acids, organic acids, fatty acids, carotenoids (β-carotenes, lycopene, zeaxanthin), tocopherols (α β, γ, δ), sterols (ergosterol, campesterol), Vitamins (A, C, E and K), phenolic and flavonoid compounds (gallic acid, caeffeic acid, ferulic acid, isorhamnetin, kaemferol, quercetin, myricetin) and isoprenols (Tiitinen et al., 2005; Anderson et al., 2009; Barik et al., 2016). All these studies are primarily based on the prominent SBT species Hippophae rhamnoides. However, Sea Buckthorn (Hippophae salicifolia) of North East India is an underutilized non-conventional plant and its potential is not yet fully explored. Very scanty literatures are available on the identification, documentation and preliminary qualitative phytochemical characterization of SBT from North East India (Basistha et al., 2010; Pradhan et al., 2015). But there is no any report on systematic qualitative phytochemical characterization of all the plant parts of SBT from North East India in general and SBT of Arunachal Pradesh in partcular.

Starch is present in the endosperm of cereal grains which provides the necessary energy during the process of germination and seedling establishment and rice starch is reported to supply 22% of global energy intake in humans (Sun et al, 2014). Starch is a semi-crystalline polymer composed mainly of linear and highly branched polymer viz. amylose and amylopectin respectively. Each polymer is composed of several D-glucose molecules and the difference lies only in the linkages between them. Amylose is a linear chain which is interlinked by α- (1→4) linkages and few branched chains (Kizil et al, 2002). Amylopectin subunits are linked by both-(1→4) and-(1→ 6), with about 95% of the glyosidic bonds being-(1→ 4) linkages and roughly 5% being-(1→ 6). The highly branched nature of amylopectin is attributed to the-(1→ 6) linkage.

1. Introduction

Pineapple (Ananas comosus) is a tropical fruit having good sensorial characteristics such as, mechanical properties, flavor, acidity/sweetness ratio, color; and nutritional. Pineapple is known to be a good source of vitamins such as vitamin C, vitamin B and antioxidants. The free radical scavenging activity of pineapple is found to be much higher than banana and is comparable to that of guava (Alothman et al., 2009). However, it is a perishable cash crop that grows in abundance in a short time. This necessitates protecting the perishable fruit against quality loss during storage and distribution.

Fruit leathers are an economic and convenient substitute for natural fruits with high nutritional components. Leathers are made by removing moisture from wet pulp until the desired cohesive “leathery” composition is obtained. Since it is light and low in moisture it has minimum storage problems and is economical to ship (Moyls, 1981). Therefore, making fruit leather from fresh fruits is an effective way to preserve fruits (Maskan et al., 2002). Furthermore, fruit leather has far fewer calories, less than 100 kcal per serving (Huang and Hsieh, 2005) and have a far greater nutritional value (e. g., especially in terms of energy, minerals, antioxidants and fiber) than the fresh fruits because all nutrients are concentrated. There are large numbers of fruit leather available in the market, such as mango leather, apricot fruit leather, grape leather, berry leather, kiwifruit leather, and jackfruit leather (Torres et al., 2015).

1. Introduction

The culinary banana (Musa ABB) of Assam and North East India (locally known as kachkal) is an important and cheap source of vegetable in the diet of local people. It is considered as one of the potential sources of carbohydrates, starch, polyphenols, micronutrients and functionally important bioactive compounds (Khawas et al., 2016). Native starches have limited use in food application as it has many weakness such as narrow peak viscosity range, poor process tolerance, low shear stress resistance, hydrophilicity, thermal decomposition, high retro gradation, and synersis and cooked starches will formed a weak, cohesive and rubbery paste. These facts motivated the employment of modified starches as important functional ingredients in processed foods in recent years because of their improved functional properties over unmodified starches (Fleche et al., 1985).

To overcome these problems physical. Chemical and enzymatic modification of Starch is done. Chemical modification of starch generally involves esterification, cross linking, etherification or oxidation of the available hydroxyl groups on the β-D-glucopyranosyl units that make up the starch polymer.

1. Introduction

Purple colour passion fruit (Passifora edulis Sims) is a tropical fruit and is well known for its nutritional content and medicinal properties (Patel, 2009). Various type of vitamin E such as α-tocopherol (5,7,8 trimethyl), β-tocopherol (5,8 dimethyl),g-tocopherol (7, 8-dimethyl),d-tocopherol (8-methyl) and α-tocotrienol, b-tocotrienol,g–tocotrierol and d- tocotrienol were quantified in passion fruit as antioxidant molecules with various health benefits (Ramaiya et al., 2013).

Foam mat drying convert thin pulp into stable foam by whipping. Eventually, the whipping process increases surface area, and speed up the drying rates which yield dried foam mat powder of acceptable quality in reduced time span (Kudra and Ratti, 2006). Rheology plays a vital role in food manufacture and marketing nowadays viz., design of handling systems, quality control and evaluation of sensory stimuli of viscosity (Barnes, 2001). It also concerns with how all food materials respond to applied forces and deformations. Basic concepts of stress (force per area) and strain (deformation per length) are keys to all rheological evaluations. Stress(r) is always a measurement of force per unit of surface area and is expressed in units of Pascals (Pa). The direction of the force with respect to the impacted surface area determines the type of stress. Normal stress occurs when the force is directly perpendicular to a surface and can be achieved during tension or compression. Shear stress occurs when the forces act in parallel to a surface. Various food shows different rheological behavior and categorized into solid and liquids stages. It basically means that food varies their characteristic in viscous and elastic behaviors commonly known as viscoelasticity of food, caused by entanglement of long chain molecules with other molecules (Abang, 2010). The dough rheology of various flour has been investigated by various research. Although, there has not been any published literature about dough rheology with incorporated passion fruit powder. To the best of our knowledge, there are no published reports regarding the shear stress properties of passion fruit powder incorporated rice dough.

1. Introduction

Organophosphate (OP) and organocarbamate (OC) pesticides are highly used in modern agriculture due to their low persistence and high insecticidal activity. Although they are relatively less persistent than the organochlorines, they have greater acute toxicity with tolerance level ranging from 1 to 8 μg mL-1 (Mulchandani et al., 2001). The high toxicity of OP and OC neurotoxins and their large use in modern agriculture practices has increased public concern, health risk and the consequent contamination of water and food sources (Buonasera et al., 2010). Development of fast and cost effective analytical tools for onsite monitoring of OP and OC contaminations in food, water and in the environment is highly necessary. An approach toward that has resulted the evolution of acetylcholinesterase (AChE) based biosensors for OP and OC pesticides. Ample literature is available on AChE based biosensors (Zhou et al., 2013). But some intrinsic disadvantages remain that limits its utility and field deployment. The most influencing ones are their inability to sustain in organic solvents and the limited class selectivity that demands alternate bioreceptor for pesticide detection. Given the diversity in mode of action of different classes of pesticide, it is quite challenging to come up with different sensor molecules for each class of pesticides. As a continuous effort towards that goal, attempts have been made to use the Glutathione S –transferses (GSTs; EC 2.5.1. 18) for the purpose. GSTs are a multigenic family of cytosolic proteins with multifunctional biological roles, widely distributed throughout the body and found in the liver, kidney, brain, pancreas, testis, heart, lung, small intestine, skeletal muscles, prostate and spleen (Jancova et al., 2010). The important biological functions those are making GSTs the focus of current research includes its catalytic role in detoxification reaction (Lumjuan et al., 2011) over expressions during phase II metabolism as well as drug resistance associated with anticancer therapies of human and the resistance acquired by certain insects while getting exposure to pesticides (Borah et al., 2016).

King chilli belongs to the genus Capsicum and species chinense, which is world famous for its heat content. King chilli measures 60 to 85 mm (2. 4 to 3. 3 inches) long and 25 to 30 mm (1. 0 to 1. 2 inches) wide with a red, yellow, orange, or chocolate color. The plant came into limelight when it was announced as the hottest chilli in the world in 2006 (Baruah et al., 2014). The people of the North-eastern India use the fruits of King chilli in different food formulations like flavouring curries due to its high-quality fragrance and pungency and also for various medicinal treatments like rheumatism, arthritis, gastritis, ankylosing spondylitis, digestive diseases (Sarwa et al., 2012) and to reduce chronic congestion (Raktim and Changkija, 2009). It is also used as a bird, animal and insect repellent as well as a biochemical pesticide. The extremely hot or burning sensation of chilli is due to the presence of capsaicinoids found only in Capsicum (Hoffman et al., 1983).

In northeastern India, King chilli has been cultivated in a traditional manner since time immemorial and there exists a considerable amount of genetic variability among the landraces (Raktim and Changkija, 2009). The pharmaceutical applications of capsaicinoids are attributed to their analgesic, antiarthritic, anticancer and antioxidant properties. In fact, capsaicin has been at the centre of intense research for elucidating the basis of its pharmacological properties and exploiting the therapeutic potential (Prasad et al., 2005). It has also been reported that capsaicin inhibits the growth of prostate cancer cells (Mori et al., 2006). The antioxidative capacity of chilli is higher than ginger, garlic, mint and onion (Shobana et al., 2000), which may play an important role in the process of chemoprevention (Yu et al., 2002).

1. Introduction

Okara is a by-product generated during processing soybean into soymilk or tofu. Okara is rich in fibre and protein. It contains most of the carbohydrates, some of the protein and a small portion of the oil from soybeans. Okara contains approximately 50% fibre, 27% protein, and 10% fat on dry basis (Li et al., 2012). About 1. 2 kg of fresh okara is produced from every kilogram of soybean processed for soymilk (Vishwanathan et al., 2011). Fresh okara from soymilk production has about 80% moisture. The protein present in okara has good nutritional quality and superior protein efficiency ratio. Other soy components that are also likely present in okara include isoflavones (genistein and daidzein), lignans, phytosterols, coumestans, saponins, and phytates (Li et al., 2012). The most common method of utilization of okara is in the form of animal feed. Tofu or soymilk processing plants primarily dump okara as landfill or resort to burning. Okara can be utilized as a fertilizer as it contains various nutrients required for growth of plants. It can be used as a fermentation substrate for production of ethanol. Okara can also be used in pet foods as it contains high levels of extenders and protein. Apart from these, okara can be used in a variety of food products. It can be used in various food products. Utilization of okara is still in the initial stage. It can be used as a replacement of wheat flour in baked products. It can also be used in various soups, salads or vegetable preparations.

Resistant starch refers to the portion of starch and starch products that resist digestion as they pass through the gastrointestinal tract. Resistant starch is the fraction of starch which is not hydrolysed to D-glucose in the small intestine within 120 min of being consumed, but which is fermented in the colon. It can be used as a functional ingredient in various food formulations (Fuentes-Zaragoza et al., 2010). RS has desirable physicochemical properties (Fausto et al., 1997) such as swelling, viscosity increase, gel formation and water-binding capacity, making it useful in a variety of foods. It helps in improving the appearance, texture, and mouthfeel of the final product compared to conventional fibres. Resistant starch can act as a prebiotic for gut microflora (Sajilata et al., 2006). It has hypocholesterolemic effects, is hypoglycaemic and prevents gall stone formation.

1. Introduction

Banana is having number of species and belongs to genus Musa of the family Musaceae. Bananas are produced in large quantities in tropical and subtropical areas. World production of Musa in 2003 was estimated at 102 million MT of which about 68% was classified as bananas and 32% as plantains (FAO, 2003). For growing banana need special climate and they are mainly produced in developing countries P (Zhang et al., 2005). The crop is of major importance to the people in the growing. The largest producer of banana is India (27%) and other countries are Ecuador, Brazil, Indonesia, Philippines and China etc. Ecuador (42. 3%), Colombia (24. 7%), Philippines, Dominican Republic, Belgium, Italy, Peru, France, Netherland, Germany are the top exporter countries in 2009.

Banana is a botanically a berry require a warm, humid, frost-free climate with optimum temperatures between 22 and 31°C. In several report it was found that banana plant die in ground level at below temperature -2°C. Primary component of the aroma of fresh bananas is isoamyl acetate which is also called as banana oil. Banana is highly energetic food and rich in potassium, sodium, phosphorus, chlorine, magnesium, sulphur, silicon, calcium; and the vitamins: A, B1, B2, C and B3 (niacin).

Jackfruit (Artocarpus heterophyllus Lam. ) a member of the family Moraceae is the largest tree-borne fruit in the world. India is the second biggest producer of the fruit in the world and is considered as the motherland of jackfruit. The jackfruit is native to parts of South and Southeast Asia and is believed to have originated in the rainforests of Western Ghats of India and is cultivated throughout the low lands in South and Southeast Asia. Major jackfruit producing countries are Bangladesh, India, Myanmar, Nepal, Thailand, Vietnam, China, the Philippines, Indonesia, Malaysia and Sri Lanka. There are 100-500 seeds in a single fruit (Sidhu, 2012). It is composed of rind, edible bulbs of yellow-flesh and seeds. The ripe fruits are eaten or processed into snacks and canned products. Seeds make up around 10 to 15% of the total fruit weight (30-365/ fruit) and have high carbohydrate and protein contents (Ocloo et al., 2010). Mostly the seeds, rind and strands are discarded as waste. So, the seed, rind and strand flour can be an alternative intermediatory product, which can be stored and utilized, both for value addition and to blend with other grain flours without affecting the functional and sensory profile of the final product.

Sundarbans is claimed to be one of the wonders of the world for its natural resources of halophytic mangrove forest (some 34 species of true mangroves are present), biodiversity and ecosystem that form an extraordinary environment of the globe. Available brackish water environment of Sundarbans provides favourable substratum for algal communities (Naskar and Naskar, 2010). Enteromorpha intestinalis specifically is one of the algal species that is very abundant in the Sundarban region. The production of total seaweeds in India in 2000 was approximately 600,000 tons (wet weight). India produces 110-132 tons of dry agar annually utilizing about 880-1100 tons of dry agarophytes. The seaweed industry in India is mainly a cottage industry and is based only on the natural stock of agar-yielding red seaweeds, such as Gelidiella acerosa and Gracilaria edulis, and algin yielding brown seaweeds species such as Sargassum and Tubineria (Kaladharan and Kaliaperumal, 1999).

Investigational studies indicate that marine algae contain significant amount of nutraceuticals, vitamins, proteins, carbohydrates, fiber and antioxidants. Composition indicates that there is a tremendous scope for food and pharmaceutical applications. These may be used for food fortification but after rigorous studies. Formulation, standarizaiton and characterization should be performed before human use. Studies for exploitation of the bioactive components of the species may open up new avenues. Hence there seems to be a full scope for the realization of outcomes of the research. Further the utilization of the developed processes at higher scales may reap in financial benefits and may prove beneficial to the local people, who are supplier of the raw materials. The present study is an attempt to utilize this India variety of macro-algae for fortification of bakery food products.

Milk is considered to be an adequate source of valuable macro nutrients, fat, protein, lactose. Vitamins and micronutrients making it a wholesome food. It can serve as an excellent carrier product for extra nutrient and if enriched or fortified it can satisfy the nutritional needs of the population. Soybean is an excellent source of low cost protein and has been an important nutritional component and medical investigation have revealed the great potential of soy foods for lowering blood cholesterol levels and the incidence of heart disease and cancer. The dry soybean contains roughly 40 % protein, 20% oil and 35% soluble (sucrose , raffinose, stachyose, etc. ). Aqueous extract of soya is an ideal substitute of animal milk for people suffering from allergic, gastrointestinal and other diseases peculiar to elderly people liu et al. (2004). Soymilk obtained by aqueous extraction from whole soybeans is a well known food product that is growing in popularity in many areas of the world (Hauman,1984). Soy milk is low in fat, carbohydrate, calcium, phosphorus, and riboflavin, but high in iron, thiamin, and niacin in comparison with cows’ milk. Soy milk contains higher amount of protein than buffalo milk and is deficient in sulfur containing amino acids. Soya milk is used in various products like paneer, yoghurts , cheese, tea and coffee whiteners , shrikhand, rasogolla and various indigenous milk sweets, confectionary, etc (Kale et al., 2012, Chang et al., 2005) also reported that intake of fermented soymilk improves the ecosystem intestinal tract by increasing the amount of probiotics. During the last years, soy beverages consumption has gradually increased due to their significant concentration of health promoting compounds, such as iso flavones.

Citrus is a common term and genus (Citrus) of flowering plants in the Rue family, Rutaceae. Citrus fruits are non-climacteric and respiration slowly declines and the production and release of ethylene is gradual. India ranks sixth in the production of citrus fruits in the world. Citrus wastes typically are about 45- 50% of the weight of citrus original and the percentage of waste to 30-50% for vegetables and fruits in general. Natural colour plays a significant role in determining the degree of consumer acceptance of the product. In addition, carotenoids (vitamin A precursor) have high nutritional values which are important for human nutrition.Francis and Isaksen (1988) stated that carotenoids play a very important role for extraction as for protection of health against cancer, cardiovascular and eye disease and as anti-oxidant. Carotenoids play important roles in human nutrition through their provitamin A activity, but also by acting as antioxidants, for prevention of age-related macular degeneration or skin protection against UV radiation. The antioxidant capacity of carotenoids was proved for pure compounds as well as for plant extracts and food. The main objective of this research work is extraction, determination and identification of natural colorants from different citrus wastes (citrus peel). Also to study the effects of pH and oxygen on the stability of extracted pigments and determination of the specific carriers for the extracted pigments using solid matrices (starch, dextrin, arabic gum and flour).

The emergence of food borne illness due to contaminated food is one of the most frequently occurring event and challenge for the food processing industry. This has resulted into economy as well as energy requirement to counter the food borne pathogens. Some of the important pathogenic microorganisms of concern are E. coli, Listeria monocytogenes, salmonella, etc. To address the food safety and quality issues, several non-thermal food processing technologies have been developed in the last decades, with an aim of achieving food safety without significantly affecting the quality of the food product. Cold plasma in one of the non-thermal processing technology, which has shown promising results as evidenced by recent scientific investigations.

The plasma is known as fourth state of matter after solid, liquid and gas state. Plasma contains diversity of energetic species including ions, electrons, atoms, excited molecules and charged particles. In a plasma, a significant number of electrons have such a high energy that no nucleus can hold them. When a gas is subjected to heat or an electric field, some of the atoms become ions and the gas is said to be ionized. An ionized gas in its normal condition, can conduct electric current to a limited extent. If the heat or electric current becomes extreme, many of the atoms become ions. The resulting super ionized gas, which can conduct a large and sustained electric charge. Plasmas are used in several materials processing industries like textiles, electronics, paper and glass industries etc.

Underutilized fruits and vegetables are commercially neglected but recognized as rich sources of nutrients and non-nutrient bioactive compounds (Ali et al., 2008). These crops are very popular among local communities in many parts of the world and well accepted in their traditional diets and therapeutic medicines (Animesh et al., 2010). Nowadays, these are gaining significance in research and development programs of many organizations. Meghalaya is endowed with rich and unique diversity of indigenous wild edible fruit species of which most of them are less known and underutilized (Haque et al., 2009). There are rich in functional bioactive components such as vitamins and minerals are the much talked dietary nutrient for women and children health. It is being supplied to body through tablets, vegetables, fruits and other food items (Islam et al., 2012).

1. Introduction

Ohmic heating is an emerging method of thermal processing which have the feature of HTST treatment (Halden et al., 1990) with lower energy inputs (Choi et al., 2011; Sastry et al., 2011). During ohmic heating (Fig. 1) the alternating current is passed through the food material, where food acts as a resistor to the flow of electric current and leads to the instant volumetric heat generation by following the Joules first law of heating (Pereira & Vicente 2010; Lima et al., 1999 and 2001; Wang, 2014). Ohmic heat treatment of food material has been found to reduce microbial load of the food material simultaneously with the inactivation of the inherent enzymes (Demirdoven & Baysal 2014; Yildiz & Baysal 2006; Jakob et al., 2010). Despite the problems of electrochemical degradation associated with it, ohmic heating has been successfully studied for its use in preheating, blanching, pasteurization and extraction (Leizerson, & Shimoni, 2005; Lima & Sastry, 1999; Lakkakula et al., 2004). A majority of studies that have explored the effect of ohmic treatment have focused on a number of commercial products from pulp (strawberry), or puree (pea) to juice (grape), etc. (Castro et al, 2004; Icier et al, 2008; Icier et al., 2006). However, the present chapter is confined to put some light on the studies conducted on ohmic heating of various liquid food material and its effects on various parameters of the food material.

Biopolymers nowadays are grabbing a nice place in packaging industries replacing synthetic polymers. The most important advantage of biopolymer over synthetic polymers is that they are biodegradable and can be developed from agricultural or food processing wastes. Among the wide variety of materials currently used in food packaging, polymers have taken a major share because of their versatility and advantageous performance (Valdés et al., 2014). However, most polymers used for food packaging are not biodegradable or compostable and therefore represent an increasingly serious end-of-life disposal problem worldwide. Although food package stability during the shelf-life of the product is an advantage, it turns into a disadvantage when the packages enter the post-use phase.

Kiwi fruit (KF) is very much acceptable for preservation by freeze-drying (FD) technique, since it has very much health benefits such as low calorific value, low glycemic index (GI), more vitamins (particularly vitamin C), maximum load of potassium, presence of variety of pigments, few important enzymes, low allergic response (AR) and finally it is rich in natural antioxidants, polyphenols. It is translucent, green pulp and many black seeds arranged nicely with covered by hairy and brown skin. The KF seeds are small sizes and black colored surround inner circularly through the whole pulp. It gives a nice crunch during consumption and provides a number of essential nutrients. Therefore, it will be remembered that seeds cannot be discarded during processing of KF unlike other fruit (jamun etc. ) seeds.

Cassava (Manihot esculenta Crantz) is a tuberous root crops. It is known as “U mangra” in Manipuri. It is also known as mandioca or tapioca, yucca, mosioc. Cassava belongs to Euphorbiaceae family The cassava plant is of perennial woody shrub in nature. (CGIR 2011; FAO-2015, Zhu 2015). Like paddy and wheat as staple food crops, cassava is also staple food crops for many countries. It supports millions of population especially in South American and African countries. It is also known as food security crop because of its ability to withstand harsh environmental conditions when other food crops cannot sustain and destroy. It can grow in low fertility soil, marginal land with less agricultural maintenance. It resists to pest and diseases so cultivation is easy to carry out with less expenditure. Cassava is abundantly grown in Manipur mostly in hilly areas. To some extent, it is consumed as snacks item either by burnt in fire or charcoal or boiled form with little addition of salt. The fresh young leaves and roots after removing its cover is used as ingredients of “singju” a salad type traditional snack items of Manipur. Out of cassava sweet snack item locally called “manghra heingan” in Manipur is also prepared. For making this sweet item, cassava is boiled with sugarcane molasses until it is cooked and reach certain sugar consistency of molasses. This sweet item is similar with murabba available in Indian market.

The growing prevalence of obesity and obesity associated disorders as well as its impact on public health has received increased attention in recent years. As a result, obesity is now considered one of the world’s leading public health problems. A study published in the noted medical journal Lancet says India is just behind US and China in this global hazard list of top 10 countries with the highest number of obese people. The study - titled ‘Global, regional, and national prevalence of overweight and obesity in children and adults during 1980-2013: A systematic analysis for the Global Burden of Disease Study 2013’ - used data collected by international bodies and organizations in various countries like India over three decades. China and India together accounted for 15 per cent of the world’s obese population, with 46 million and 30 million obese people, respectively. According to the study, the number of overweight and obese people globally increased from 857 million in 1980 to 2. 1 billion in 2013. This is one-third of the world’s population.

With lifestyle disorders forcing more and more people to reel under excess body weight, even relatively younger people are developing joint disorders and knee pain. Excessive weight is associated with a series of health problems, including blood pressure, diabetes, and cardiovascular ailments. Therefore there in an urgent need to envision effective anti-obesity strategies through effective interventions.

1. Introduction

With increase in consumer awareness and lifestyle the interest for health promoting natural food ingredients has expanded in recent years. However, globally it has become a great challenge to the manufacturers to ensure that such compounds should remain in their active form during processing and storage with an emphasis to its bioavailability profile. Oxidative stress is the major contributor to the pathogenesis of a number of chronic and degenerative diseases including atherosclerosis, Alzheimer’s and Parkinson’s disease, diabetes, DNA damage, carcinogenesis, cardiovascular and neuro degenerative diseases, allergies, premature ageing etc. (Gupta et al. , 2014; Svetli et al. , 2010). Endogenous antioxidant defense mechanisms are not always sufficient to fully scavenge the free radicals formed in the body during various processes. Therefore, dietary components having antioxidant properties, such as tea flavonoids, are very much necessary to supplement the activity of endogenous antioxidants. Tea is one of the most concentrated sources of flavonoids and phenolic acids which show antioxidant activity by sequestering metal ions and by scavenging reactive oxygen and nitrogen species (Frei & Higdon, 2003).

1. Introduction

Jackfruit is the largest edible tree borne fruit in the world (Baliga et al., 2011). According to Haq (2006) India is considered as the birth place of jackfruit. The major jackfruit producing states in India are Assam, Tripura, Bihar, Uttar Pradesh, the foothills of the Himalayas and South Indian States of Kerala, Tamil Nadu and Karnataka. Jackfruit is a fruit prized in some areas of the world and allowed to go waste in others. According to Sidhu (2012) the extent to which jackfruit is being wasted in India is not exactly documented however, the wastage is approximately 75%. On an average a fully developed fruit may weigh 10-25 kg. Seeds occupy around 10 to 15% of the total weight of the jackfruit (Bobbio et al., 1978). It is reported that jackfruit seeds contain high amount of protein, fiber and carbohydrate (Ocloo et al., 2010). The seeds are viable for not more than three or four days (Sidhu, 2012). According to Abedin et al. (2012) the industrial utilization of jackfruit pulp are varied but the seeds are discarded from those food industries. Moreover, mature fresh seeds cannot remain fresh for long as they tend to germinate easily. So, converting jackfruit seed into flour is an option in order to increase the shelf- life of the seed and can substitute various cereal based flours for developing food products. Dumpling is a type of food which is made out of small pieces of dough wrapped around a filling that may include vegetables, meat, or other ingredients mixed together.

1. Introduction

The term nanotechnology was first coined by Norio Taniguchi in 1974 to describe controlled thin film deposition (Taniguchi, 1974). Nanotechnology is now generally recognized to include materials with a size in at least one dimension in the 1-100 nm range, although this terminology is not strictly enforced (Rao, 2008). In food science, there are many types of naturally occurring particles that fall within this size range and the use of a strict definition is problematic due to the large distribution of sizes (Kruif, 1998). Many natural foods contain nanoscale components and their properties are determined by their structure. These have been eaten safely for generations. In fact, some of food’s most important raw materials (proteins, starches, and fats) undergo structural changes at the nanometre and micrometre scales during normal food processing(Morris and Parker 2008). Food proteins (for example, native beta-lactoglobulin, which is about 3. 6 nm in length) can undergo denaturation (via pressure, heat, pH, etc. ) 

1. Introduction

The Refractance Window drying system uses circulating hot water, usually at 90°C and at atmospheric pressure, so that it can carry the thermal energy to the material to be dehydrated. Thermal energy is transferred to the wet product from circulating hot water through a plastic interface which is transparent to the infrared radiation. The actual product temperature is kept below 70°C. The heated water is recycled and reused, which helps in improving the thermal efficiency of the system. The use of hot water as the heat transfer medium and at temperatures just below boiling is a design feature that is unique to this drying method. In RW drying, there are three modes of heat transfer, namely conduction, convection, and radiation. The process water is heated by steam within an insulated tank and then circulated in shallow troughs to transfer thermal energy to the plastic conveyor. As the plastic conveyor is very thin, it reaches the temperature of hot water flowing beneath it almost immediately. By conduction and radiation, the thermal energy from the hot water is transmitted through the plastic conveyor. The use of process water at temperatures just below boiling and a thin plastic conveyor with infrared transmission in the wavelength range that matches the absorption spectrum for water all work together to facilitate rapid drying.

Rasogolla is a sweetened dairy product which is made from milk mainly from casein protein. Generally rasogolla is made by heating the raw milk around 80-850C ,then slowly cool the milk around 650C and acid coagulation of the milk is done. Then separate the channa (mainly casein) and whey, and drained the whey followed by the pressing of the channa to remove the excess water. Then channa is thoroughly kneaded and are rolled to balls and cooked in sugar syrup and get the rasogulla. Total value of 1000 billion for Indian dairy output in 2001, the output of traditional dairy products is estimated at over 400 billion. The share of the organized sector in the indigenous products is at present only 50 billion only (Patil, 2005).

Cherry peppers (Capsicum frutensis var. cerasiforme) which is locally known as dallae khorsani, is one of the important cash crops of Sikkim and Darjeeling hills. They are small, round shaped, fleshy and heavily seeded. They are green in color in early stage of fruiting and turn red when fully matured. It is an excellent source of vitamin A and C, which are important antioxidants (Howard et al., 1994). Cherry peppers are an ideal size for pickling or brining. Its hotness ranges from moderately mild to very high.

Due to its high moisture content (about 85% w. b. ), shelf life of cherry pepper is limited to 7 - 10 days. This makes it rare and costly during the off season. Hence, preservation of cherry peppers is of considerable importance both to the farmers as well as to the consumers. Drying is one of the oldest methods for preservation of cherry peppers to make it available throughout the year. To increase shelf life of chilies, drying up to 10 % moisture content (dry basis) is required which is accepted in export market.

For drying chillies, sun and hot air drying are the most common drying method used. However, due to the prolonged drying time of 16-48 h, the quality of the dried chillies is reduced (Kim et al., 2002). Many researchers paid more attention to innovative techniques such as short and medium-wave infrared radiation drying (SMIR) which not only maintain product quality, but also increase the drying rate. Moreover, infrared drying could save up 50% energy compared to convective drying (Nowak & Lewicki, 2004). The ability of infrared radiation to penetrate and heat the inner layers results in higher rate of heat and mass transfer (Ginzburg, 1969).

1. Introduction

Osmotic dehydration is a useful treatment of dehydration compared to the other dehydration processes, as other dehydration processes bring adverse and irreversible changes in physical and nutritional status of food material. Recently in many studies it was found out that since plant membranes are semi-permeable in nature, not only moisture but transfer of solute from osmotic solution to the food material also takes place. Another kind of transfer which was also noticed is the leaching of micronutrients from the cells of food to the osmotic solution, but the amount being very low, this transfer can be neglected. (Mayor et al., 2006). The mass transfer kinetics was studied for different food materials (Hawkes and Flink, 1978). Effect of different variables such as pressure and temperature were also studied (Rastogi and Niranjan, 1998). The effective diffusivities for both water loss and solute gain can be calculated by using various methods which gives the rate of diffusion of solute and moisture for the food material. The finding of solute gain and leaching of micronutrients pointed the requirement of maintaining the osmotic dehydration process, which could be done by maintaining the process variables of osmotic dehydration. Impact of various process variables on osmotic dehydration and their best levels at which maximum water loss and minimum solute gain could be obtained had to be calculated out. For this purpose, optimization of process variables through response surface methodology (RSM) could be best utilized (Uddin et al. , 2004). RSM is a statistical tool which gives the random combinations of input variables to give the best output result as required. Various works have been done on optimization of process conditions of osmotic dehydration taking different samples of foods. In this study, bamboo shoot species (Bambusa balcooa) was taken as sample for osmotic dehydration to optimize the process variables for osmotic dehydration of bamboo shoots using salt as osmotic agent followed by calculation of effective diffusivity of water and solute during osmotic dehydration of bamboo shoot.
