One of the greatest achievements in science is the development of vaccines. Vaccines have been revolutionary for the prevention of infectious diseases. They have prevented a large number of deaths caused, every year, by dreadful diseases like smallpox, polio, hepatitis etc. Diseases like smallpox and polio have been successfully eradicated by vaccination. Normally, when the body encounters a microbe, both humoral and cytotoxic immune responses are induced to neutralize its effect. In addition to eliminate the invader, body forms memory cells which help the body to protect itself from the same pathogen, in future. Vaccines not only function to kill the pathogens but they also stimulate the body to form memory cells which provide immunity against a specific pathogen

One of the most promising areas of veterinary research these days is cancer immunotherapy and the development of CMT vaccines. DNA vaccines, also known as gene vaccines, are designed to transfer functional genes to target cells, allowing them to express functional proteins. Because endonucleases may easily access bare DNA, it requires a reliable and safe delivery route, which might be biological or non-biological. Different delivery strategies have been tried in human breast tumors to transport tumor antigens such Mucin-1 (MUC-1), Twist, HER-2, mammaglobin-1 and p53, as well as immunostimulatory molecules like IL-12 and IL-6. There have been various studies/ trials in canine animals using different molecules like IL-12, HER-2 and IFN-γ as vaccine candidates, with no clinically relevant outcomes or longlasting cell mediated and humoral immune response outcomes

A vacuum cleaner, also known as a sweeper or hoover, is a device that uses an air pump (a centrifugal fan in all but some of the very oldest models), to create a partial vacuum to suck up dust and dirt from fl oors and from other surfaces such as upholstery and draperies.The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil.

Abstract

Drying is an age old practice of food preservation. Removal of moisture from the food materials is usually carried out at atmospheric pressure and elevated temperature. In the presence of oxygen, drying can cause oxidation of some compounds leading to quality deterioration. Drying at higher temperature adds to the losses and can be responsible for enzymatic and non enzymatic browning, loss of aroma, nutrients, antioxidants, pigments etc. On the other hand, drying under sub atmospheric pressure helps in retaining the themosensitive compounds present in natural foods as drying can be accomplished in oxygen free environment. Under vacuum, evaporation of moisture can be possible at lower temperatures.

There is ever increase in the demand for good quality food product with improved quality and shelf life. Over the years, packaging have brought out a revolution in the marketing and distribution of food products including fish. Among the food categories, seafood ranks 3^rd with respect to consumption which explains the importance of fish. Fish is a vital source of food for people. It is the most important single source of high-quality protein, providing approximately 16% of the animal protein consumed by the world’s population (Food and Agriculture Organisation (FAO), United Nations, 1997). By any measure, fishes are amoung the world’s most important natural resources. Annual exploitation from wild populations exceeds 90 million tones, and total annual trade exceeds $ US 55 billion. Additionally, with over 25000 known species, the biodiversity and ecological roles of fish are being increasingly recognized in aquatic conservation, ecosystem management, restoration and aquatic environmental regulation.

Like any other food commodities, fish is one of the highly perishable items which undergoes spoilage if sufficient care is not taken. Various preservation methods have been in place to overcome the spoilage of fish. Chilling and refrigeration is the most preferred preservation method as it helps in preserving fresh like quality. Chilling or icing is reducing the temperature of fish so as to prolong the lag phase of bacteria and helps in reducing the spoilage rate. Fish being one of the most perishable foods, its freshness is rapidly lost even when stored under chilled conditions. Further, consumers demands to have fish in as fresh a state as possible so that the characteristics flavours are retained. Bulk transportation of fresh fish in ice has several limitations like limited extension of shelf life, unnecessary expenditure on freight due to ice, difficulty in handling and maintaining hygienic conditions due to leaching of ice melt water with leaching losses of soluble nutrients and flavouring compounds. Proper packaging will help in improving the keeping quality of fish. Packaging is an important aspect for improving the shelf life and marketability. Packaging enhances the consumer acceptability and hence saleability of the product. Traditionally, food packaging is meant for protection, communication, convenience and containment. The package is used to protect the product from the deteriorative effects of the external environmental conditionals like heat, light, presence or absence of moisture, pressure, microorganisms, and gaseous emissions and so on. Packaging is an integral part of the food processing and plays an important role in preventing or reducing the generation of waste in the supply of food. Packaging assists the preservation of the world’s resources through the prevention of product spoilage and wastage, and by protecting products until they have performed their function. Basic requirements of a package are good marketing properties, reasonable price, technical feasibility, utility for food contact, low environmental stress, and suitability for recycling. Simply packing fish is suitable packaging material will enhance the shelf life of chilled and refrigerated fish to 7 to 15 days depending on fish species. However, in the normal packaging the spoilage process will be accelerated due to presence of O₂ in the normal air packing. Alteration in the package atmosphere will help in overcoming the problem of shelf life, which can be achieved by vacuum packaging or modified atmosphere packaging.

Vaginal prolapse in cow is a condition in which there is protrusion of whole or part of vagina including sometimes the part of cervix through the vulva. It occurs in cow mostly during last 2-3 months of gestation. It occurs due to excess secretion of estrogen from placenta, hypocalcaemia, inadequate exercise, bulky food like roughages etc. Sometimes occurs in non pregnant cows due to cystic ovaries, severe straining due to vaginal irritation etc.

1. Introduction

Valeriana jatamansi Jones is considered to be highly endangered medicinal plant found mainly in northern part of Himalayan region. Although it is also found in all temperate regions of world except in Australia (Jain, 1968; Polunin and Stainton, 1987; Bennet, 1987). It is grown in Himachal Pradesh, northern part of U.P., Sikkim and newly introduced in West Bengal Darjeeling region by us. It is enlisted in the endangered category by IUCN (Kaul and Honda, 2000) and it is enlisted as an endangered species in the national medicinal plant board, New Delhi (www.nmbp.nic.in). The plant was reported to be found in fragmented populations in different places of Kashmir Himalayan hilly region like Dara, Sonamarg, Harwan, Gulmarg, Ferozpur, Pahelgum, Yusmarg, Shajnar (Naqashi and Dar, 1982-86). It is found to be in the margin of extinction from the world though it is widespread in the temperate regions of whole world except Australia (Nayar and Sastri, 1998). Indiscriminate collection of rhizomes from the plants made potential threat of its existence in some previously founded localities (Wyatt, 1981; Nayar and Sastri, 1998; Airi et al, 2000; Nautiyal et al, 2003, CAMP, 2003).

ABSTRACT

Butea monosperma (Lam.) Taub, knownas ’Flameof the Forest’is used in Indian traditional system of medicine, such as Siddha Ayurveda, and Unani due to its medicinal properties. It is used in treatment of diabetes, diarrhoea, sore throat and reported to possess several biological activities such as anti-asthmatic, anti-diabetic, antifertility, anti-tumor and osteogenic. Recent studies revealed the phytochemicals responsible for osteogenic activity in the bark of B. monosperma. An ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method was developed for identification and simultaneous quantitation of bioactive compounds from B. monosperma. Validation of the developed method was performed according to international conference on harmonization guidelines. Quantitative interpretation showed significant variations in the content of bioactive compounds in different parts of the plant and samples collected from three geographical regions. Principal component analysis was also used to study the quantitative variations of markers.

Review of Health Claims

Regulators of different countries have different procedures and views to review health claims of traditional medicine, herbal medicines, botanicals, functional foods, nutraceuticals, health products, diatory supplements and such other natural forms of materials intended to use for health promotion. However, if such products carry any therapeutic or health benefit claims then the regulators may provide general guidance and demand for sufficient evidence base in support of such claims. For instance, U. S. Food and Drug Administration, Center for Food Safety and Applied Nutrition (CFSAN) provides general guidance to review of health claims in functional foods and dietary supplements. Ethnopharmacological preparations involving herbal medicine and traditional medicines prepared from natural ingredients also will need similar process. The scientific review process for health claims of such products is comprehensive and mainly focuses on review of individual studies³²⁴

Validation of IDM technologies is ultimate test for IDM knitted with available technologies under ground realities of the field. Since IDM is multidisciplinary, multiorganizational and multi-locational participatory approach, involvement of all the stakeholders, including farmers and field technicians is to be ensured. The following guidelines have been used as spirit behind the methodology of IDM validation.

• General considerations

 • Steps in validation

 • Step1- Feasibility studies

 • Step 2- Assay development and standardization

 • Step 3- Determining assay performance characteristics

 • Step 4- Monitoring validity of assay performance

 • Step 5- Maintenance and enhancement of validation criteria

 • Measurement of uncertainity of a diagnostic test

Lanolin, commonly known as Wool grease is primarily a lipid secretion from sebaceous glands of wool bearing animals. The role of Lanolin in nature is to protect wool and skin of animal from climate and the environment. It is an excellent emollient, self-emulsifying and dermatological safe for skin applications. Lanolin is a complex matrix since it is a mixture of high molecularweight esters of fatty acids with fatty alcohols, sterols, tri-terpene alcohols; diesters, long-chain alcohols & diols, long-chain fatty acids and hydroxy acids and is therefore difficult for effective matrix clean-up. Because of its water proofing and antimicrobial properties, lanolin is used mainly in cosmetic and pharmaceutical applications.

Validation in the pharmaceutical and medical device industry is defined as the documented act ofdemonstrating that a procedure, process, and activity will consistently lead to the expected results. It often includes the qualification of systems and equipment. It is a requirement for Good Manufacturing Practices and other regulatory requirements. Since a wide variety ofprocedures, processes, and activities need to be validated, the field of validation is divided into a number of subsections including the following:

Reliability aims at assessing the accuracy and consistency of whatsoever the measuring instrument measures irrespective of whether we are measuring what we are supposed to measure or not. Whereas the validity emphasises on the question “are we measuring what we were supposed to measure?”

To clarify the difference between reliability and validity, let us take an example of instruments that measure colour intensity. Assume, an expert develops two separate instruments X and Y to measure the intensity of green and red colour, respectively. But, the commercial manufacturer wrongly tags the red colour measuring instrument as X. When someone uses this wrongly tagged instrument for measuring the green colour intensity, whatever intensity values the instrument yields are reliable but not valid. It is so because the instrument is measuring red colour intensity accurately (hence data is reliable) but it is not measuring what it was supposed to measure –the green colour intensity (hence data is not valid).

Validity : The degree to which a measurement actually measures or detects what it is supposed to measure.

Value added : This usually refers to firms, where it is defined as the value of the firm’s output minus the value of all its inputs purchased from other firms. It is therefore a measure of the profit earned by a particular firm plus the wages it has paid. As a rule, the more value a firm can add to a product, the more successful it will be. In many countries, the main form of indirect indirect taxation is value-added tax, which is levied on the value created at each stage of production. However, it is paid, ultimately, by whoever consumes the finished product. Another definition of value added refers to the change in the overall economic value of a company. This takes into account changes in the combined value of its shares, assets, debt and other liabilities. Part of the pay of company bosses is often linked to how much economic value is added to the company under their management.

Value at risk : Value at risk models, widely used for risk management by banks and other financial institutions, use complex computer algorithms to calculate the maximum that the institution could lose in a single day’s trading. These models seem to work well in normal conditions but not, alas, during financial crises, which is arguably when it is most necessary to know how much value is at risk.

The increasing global emphasis on sustainability and the circular economy has brought renewed focus to the valorization of agri-biomass and organic waste—the process of converting low-value, often discarded residues into highvalue products. Agricultural biomass, including crop residues such as straw, husks, and stalks, along with organic waste like food scraps, animal manure, and agro-industrial by-products, is both abundant and underutilized, particularly in developing regions. Traditionally, these materials have been disposed of through open burning, landfilling, or natural decomposition, all of which release significant quantities of greenhouse gases and contribute to environmental degradation. However, recent innovations in green technology and material science are transforming these waste streams into valuable resources. Through processes such as pyrolysis, fermentation, and biochemical conversion, agri-biomass and organic waste can now be converted into biochar, bio-based chemicals, and sustainable biomaterials. These products not only mitigate environmental harm but also create new economic opportunities across agriculture, industry, and the renewable energy sector. By leveraging these advancements, societies can significantly reduce waste, lower emissions, and accelerate the transition to a more sustainable and circular bioeconomy.

Introduction

Agricultural and food wastes pose a multifaceted challenge with far-reaching implications. The staggering amount of waste generated annually not only burdens the environment but also strains economies and impacts societal well being. With the continually increasing demand for agricultural products, this issue becomes even more pressing (Gustavsson et al., 2011). Agricultural and food wastes contribute to reduction of greenhouse gas effect, soil and water pollution, and conservation of biodiversity. Improper disposal methods, such as open burning or dumping, exacerbate these problems. Moreover, the resources invested in producing these wasted goods, such as water, energy, and land, are essentially squandered. From an economic standpoint, the mismanagement of agricultural and food wastes shows loss of potential value. These wastes could be utilized for various purposes, such as energy generation, composting, or animal feed, thus creating opportunities for economic growth and innovation. Food insecurity remains a pressing issue in many parts of the world, yet a substantial portion of food produced is lost or wasted. Redirecting these surplus resources to address hunger and malnutrition could have significant social benefits, enhancing food security and improving quality of life for millions. Incorporation of sustainable farming practices to minimize waste generation, improving harvesting and post-harvest techniques to reduce losses, promoting circular economy principles to maximize resource efficiency, and raising awareness among consumers about the importance of reducing food waste. Development of new waste-to-energy technologies, biodegradable packaging alternatives, or novel methods for converting waste into valuable products. Ultimately, by mitigate its adverse effects on the environment, economy, and society, while simultaneously creating opportunities for a more sustainable and resilient future.

Introduction
Glycerol, a colourless and odourless sweet viscous liquid, is a prominent member of the polyol family—compounds distinguished by their multiple alcohol groups. Chemically known as 1, 3-propanetriol and commonly referred to as glycerine, it contains three hydroxyl (-OH) groups, which contribute to its hygroscopic nature and chemical versatility. As an essential component of lipids, glycerol forms the structural backbone of fats and oils, underscoring its biological and chemical significance. Over the years, glycerol has transitioned from being a laboratory curiosity to becoming a cornerstone of modern industrial processes, thanks to its versatility and renewable sourcing (Zhu et al., 2024).
Modern Applications and Industrial Importance of Glycerol
1. Chemical Industry: As a versatile platform chemical glycerol supports the creation of acrolein, propylene glycol and polyhydroxyalkanoates derivatives. Catalytic transformations allow glycerol to produce glycerol carbonate which finds application in lubricants, solvents and polymer synthesis research (Aranda et al., 2009). Glycerol demonstrates essential functionality in the creation of hydrogen and syngas which results in more eco-friendly manufacturing methods.
2. Pharmaceuticals and Cosmetics: The humectant and lubricant properties of glycerol make it essential for pharmaceuticals and cosmetics where it maintains moisture in cough syrups, lozenges, and skin creams while improving texture. The medical derivative glycerol trinitrate provides essential treatment for angina pectoris which results in substantial therapeutic advantages (Binod et al., 2011).
3. Food Industry: Glycerol functions as a humectant and preservative, maintaining moisture in products like dried fruits, confectioneries, and beverages. In formulations free of sugar, it also serves as a sweetener (Awogbemi and Von Kallon, 2022).
4. Animal Feed: A economical energy source for cattle, crude glycerol, a biodiesel byproduct, helps sustainable agricultural methods (Mekunye and Makinde, 2024).
5. Energy and Environmental Sustainability: Glycerol is used in biogas development to improve methane yields and helps the development of bio refineries for converting waste glycerol into biofuels, lipids, and other sustainable chemicals (Peng et al., 2023).
6. Other Applications: Glycerol finds usage as a concrete addition for enhanced durability and in antifreeze compositions in the building and automobile industries. In printing, paper manufacture, and microbial fermentation techniques, it also finds roles as a plasticiser, lubricant, and carbon source (Solowski et al., 2020).

7.1 Introduction
Valorization in simple terms means to increase the value of a product, in economics it is usually through government and administrative actions. In the concept of waste management, it is defined as the process of reutilizing or making a new product of value from waste sources. Several kinds of wastes can be transformed into materials and energy of value, one such example is agricultural wastes. These agricultural wastes are eligible to be a base for manufacturing refined commodity (Capanoglu, Nemli and Tomas-Barberan, 2022) such as chemicals, adsorbents, pharmaceutical products, acids, chitosan, certain type of wax esters, pigments etc. or can be used in several industrial or domestic processes as an energy source, most commonly the production of bioethanol. Valorization greatly contributes to circular economy as materials are continuously renewed and reused, minimizing the need for virgin resources. By transforming agricultural wastes into value – added products, valorization helps to close the loop, ensuring that each by – product is put to use in an efficient, affordable and green way, thereby reducing the dependance on conventional waste management techniques such as landfills and incineration. Moreover, valorization has other benefits, including improved public health, development of newer industries in the material recovery and processing and waste management sector. It can also bring about social awareness about sustainable practices, fostering responsible consumption and waste disposal behaviors.
7.2 Types of Agricultural Wastes
Generally, agricultural wastes are organic. The most common types of agricultural wastes are biomass from rotten produce, crops, livestock carcasses, dead leaves, droppings from livestock and straws. These organic wastes have vast potential in being converted to value – added products through various methods without much additional treatment. Inorganic wastes such as heavy metals like Pb, Cu, Hg and Ba are also found in agricultural runoff containing pesticides, paints etc. Figure 7.1 (Omojola Awogbemi et al. 2022) provides various examples of agricultural wastes that are commonly used in the production of materials and energy.

ABSTRACT

Approximately 30 % of fruits and vegetables are getting wasted each year in country like India. Not only that, there is a huge loss of agro based commodity during industrial processing and will be considered as industry generated waste. Utilization of such unexplored nutrients from agro processing sectors for making a sustainable food system will be a healthy approach to bring food security and nutrition to all of us. With this aim the present work addresses the utilization of jackfruit seeds, an agro-waste, to value added products. Jackfruit seed flour has a great potential in new food formulation along with wheat flour. The 15% (w/w) blending of jackfruit seed flour with wheat flour could be used in bread and the substituted bread is protein and fibre enriched. This attempt in developing such bakery items with blended flours could address the scarcity problem of non-wheat producing countries. Present study also looks into the alternate source of starch from spice processing industries. The nutrient starch could be explored for isolation from a nonconventional source from turmeric processing sector. The isolated starch could also be modified to enhance some of its functional properties and may be utilized in preparing value added product with a better acceptability and nutrition.Thus, the isolation of nutrients and value-added products out of fruits and vegetables and spice-processing waste would be a stepping stone to an initiative to zero hunger.

ABSTRACT

Granite in the present day context is popularly known as the principal raw material in construction industry and also known for its value addition product as Dimension Stone in the global market. India is in pride possession of much sought granite varieties of the world. No doubt the demand for such granite varieties is quite high both for local and export markets but in reality the failure rate of granite quarries is also high, The technical reasons attributed for such failures being lack of application of proper scientific skill both in selection and mining ofgranite deposits. The past experience in the fieldof granite exploitation has thought us a lesson for application of geological knowledge in selection of right deposits and in adopting the right techniques. The selection criteria for construction purpose and for export market though looks simple, is more complicated in the case of dimension stone granite deposits, the reasons being the requirement of thorough knowledge in petrography,structure,geotechnical characters of the deposit. Considering the importance of the scientific knowledge, the present paper focuses on the various parameters for valuation of granite deposits. In other words, it emphasizes on arriving at a logical conclusion by applying the scientific knowledge in successful exploitation of the much valued granite deposits.

24.1 Introduction

Egg Products have gained great acceptance all over the world to-day as they offer advantage in labour saving and time in preparations, space saving and consistency in quality. There is also an an increase in consumer demand for a variety of preparations to suit their taste and purse. Today’s commercial bakeries, food processing plants and institutions use tremendous quantities of liquid bulk eggs, egg solids (dried egg) and frozen egg products for preparation of several convenient foods.

Dry Flower Products

Dry flowers are aesthetically beautiful and they enhance the décor and liveliness of any room. They bring the fiery warmth and bounty of the season into the home with ease every fall. Much of fall’s beauty lies in the glorious changing colors of autumn leaves. These flowers are dried to use them in a wide range of products. Dried floral products are widely used for decoration and for adding zest to a room. Apart from that they are also used as an essential component of many products. They are widely used to make handmade paper, lampshades, candle holders, jute bags, photo frames, boxes, books, wall quilts, topiary, cards and several gifts. The use of dry flowers in the making of these products enhances the appearance and beauty of these products. They look sophisticated when gifted to someone or used as a décor of your own home.

Value addition is the most talked about word in food processing industry, particularly in export oriented fish processing industry because of the increased realization of valuable foreign exchange. Value can be added to fish and fishery products according to the requirements of different markets. These products range from live fish and shellfish to ready to serve convenience products. As far as fish processing industry is concerned value addition is one of the possible approaches to raise profitability since this industry is becoming highly competitive and increasingly expensive.

There is great demand for seafood/seafood based products in ready to eat “convenience” form. A number of such diverse products have already invaded the western markets. One factor responsible for such a situation is more and more women getting educated and taking up employment. Reasonably good expendable income, education, awareness and consciousness towards hygiene and health, increased emphasis on leisure pursuits etc. are some of the other reasons.

Marketing of value added products is completely different from the traditional seafood trade. It is dynamic, sensitive, complex and very expensive. Market surveys, packaging and advertising are a few of the very important areas, which ultimately determine the successful movement of a new product. Most of the market channels currently used is not suitable to trade value added products. A new appropriate channel would be the super market chains which want to procure directly from the source of supply. Appearance, packaging and display are all important factors leading to successful marketing of any new value added product. The retail pack must be clean, crisp and clear and make the contents appear attractive to the consumer. The consumer must be given confidence to experiment with a new product launched in the market. Packaging requirements change with product form, target group, market area, species used and so on. The latest packaging must also keep abreast with the latest technology.

Abstract

Mango pulp is high in prebiotic dietary fibers vitamin c, polyphenols, carotenoids, vitamins and dietary minerals. Mint leaves are known for its medicinal aromatic and flavorsome qualities. Mint act as powerful antioxidant, protecting the body against the formation of cancerous cells and is rich source of polyphenolic compounds. Tulsi also have antioxidant, adaptogenic, anti-inflammatory, antibacterial and immune-enhancing properties. Honey is natural sweetener and has antiseptic and antibacterial properties. Medicinally, honey is non irritant promote rapid growth of healthy tissue and is useful in purities value, bed spores, skin and intestinal disorder, etc. Keeping in mind the beneficial effects of these raw materials, attempt was made to prepare value added drink from it, which may have medicinal value and good sensory acceptability with objective to prepare and evaluate the recipe for value added green mango-mint-tulsi beverage and to study the shelf life of the developed value added beverage. The formulation prepared with partial substitution of honey was more acceptable. Throughout the storage period, the squash prepared with honey scored more in flavor, taste, mouth-feel and overall acceptability than without honey. The cost of production without including labour, bottling and other overhead charges came out to be Rs. 34.5/L for squash without honey and Rs. 59.0/L for squash without honey.

Value Addition in Livestock Product

Mankind has been utilizing different animal species from the dawn of civilization for a variety of purposes viz. production of milk, meat, wool, egg and leather etc. These products are either useful in raw form or in value added form. Value-addition describes economically adding value to the product by changing its place, time and form to characteristics that are more preferred in the market place. Another way of explaining is that what happens when you take a basic product and increase the value of that product, usually the price by adding extras in the manufacturing process, or by tacking on extra products and/or services.

India is bestowed with diverse agroclimatic zones which aids in the cultivation of large number of commercial flowers like rose, gladiolus, chrysanthemum, tuberose, jasmine, marigolds, orchids, lavender, lily, anthurium, gerbera, potted plants, cut foliages, bedding plants etc. In floriculture trade, value addition takes place at every step to create a novel product and to cater the demand of heterogeneous consumers. In the international floriculture trade, besides floriculture and pot plants, many other value added products include artificial colouring of the flowers to create novelty, aqua-packing for better presentation and attraction, three dimensional window packing of flowers for greater visibility, garland, venis, bouquets, flower arrangements etc.

1. INTRODUCTION

Food processing industries are engaged in production of different types of processed products and generate various types of wastes. These wastes, whether solid or liquid, on one hand are a direct loss to the producer or manufacturer and on the other hand create environmental pollution, if not disposed properly. Therefore, the processors would always like to minimize these wastes. The generation of wastes not only cause economic losses but would also require additional cost for their management and disposal. As a matter of fact, it is often estimated that proper use of efficient machinery and careful handling during various operations can lead to more than 50% reduction in losses.

In general, the wastes from the food processing industries are either not utilized or primarily utilized as animal feed, fertilizer and in preparation of by-products on a limited extent. Many of the wastes such as cuttings and shreds from the fruit and vegetable processing industry can be used as animal feed. Fruit and vegetables wastes can also be used for extraction of starch, pectin, natural colouring matter, fat, essential oils etc. Wheat and maize bran alongwith palm kernel are used for the production of feed for chickens. Various oils and oleoresins having enormous pharmaceutical properties can be obtained from the spice processing industry.

Fermentation is a cheap and energy efficient means of preserving perishable raw materials. It commonly does not require any sophisticated equipment, neither is the storage of fermented products a big issue. Fermented foods play an important role in providing food security, enhancing livelihoods and improving the nutrition and social well being of millions of people around the world, particularly the marginalised and vulnerable population across the developing countries.

Introduction

Fruits and vegetables are very important in a balanced diet. India has become the second largest producer of fruits and vegetables. Though, the production of fruits and vegetables make us believe in our strength for self-sufficiency, a significant qualitative and quantitative loss occurs in the produce from harvest till consumption. For self sufficiency and also for processing, export and to meet additional requirements, a lot of emphasis need to be given to reduce post harvest losses besides increasing production and productivity of fruits and vegetables. Though, processing plays an important role in conservation and effective utilisation of these perishable commodities, only less than three per cent of total production of fruits and vegetables are processed in India. The new industrial policy has placed this sector in the list of high priority areas.

Fruit and vegetable processing industry in the country is in a nascent and primitive stage. Number of establishments in the organized sector is less compared with several developed and developing nations. The technologies adopted for processing, preservation and value addition in medium, small and tiny industries are primitive and outdated. Processing of fruits and vegetables into various products using proper cost effective technology is a viable tool for improving economic status of farmers as well as our country. Fruit and vegetable preservation methods are broadly classified as (i) Physical methods: This includes removal of heat, addition of heat, removal of water and irradiation, (ii) Chemical methods: like salting or brining, addition of sugar and heating and by addition of chemical preservatives, (iii) Fermentation and (iv) Judicious combination of one or more of the above methods for synergistic effect.

Orchids comprise the largest family of flowering plants with 25,000 to 35000  species belonging to 600-800 genera. They are prized for their incredible diversity in the size, shape and colour and attractiveness of their  flowers and high keeping qualities even upto 10 weeks. In the international trade, among   top ten cut flowers, orchids rank the sixth position and among orchids Cymbidium ranks the first position and in floricultural crops it accounts for 3% of the total cut flower production. In India, it comprises 140 genera and 1300 species which grow upto an elevation of 5000m. Indian terrestrials are located in humus rich moist earth under tree shades in North Western India.  Western Ghats harbour the small flowered orchids. Epiphytic orchids are common in North eastern India which grow upto an elevation of 2000m from sea level.

Introduction

The food processing sector is highly fragmented industry, it widely comprises of the following sub-segments: fruits and vegetables, milk and milk products, beer and alcoholic beverages, meat and poultry, marine products, grain processing, packaged or convenience food and packaged drinks. A huge number of entrepreneurs in this industry are small in terms of their production and operations, and are largely concentrated in the unorganized segment. This segment accounts for more than 70% of the output in terms of volume and 50% in terms of value. Though the organized sector seems comparatively small, it is growing at a much faster pace.

The food processing industry can be classified into three categories: organized (25%), small scale (33%) and unorganized (42%) (Source: FAIDA/ Minstry of Food Processing Industries). The share of food processing in total manufacturing is only 9% in India.

Several products of fruits and vegetables are prepared on commercial and home scale. Products development from fruits and vegetables is the best way to utilize excess produces and save them from post harvest losses..

Value Addition

This is the process of improving the value of a commodity through processing by changing its form, increasing its shelf life or better presentation like packaging. Value addition can be done through the ways.

Annual plants complete their life cycle within the space of one year are called annuals. They have multipurpose uses like as cut flowers, a wealth of bloom through out the summer and early autumn months; as component in herbaceous border, to make colour scheme, for window boxes and porches, as pot plants in green house or conservatory, for edging, for drying and herbal medicines.

Aquatic plants are essential to maintain water balance. They also keep out the dreaded algal bloom. Aquatic plants absorb the minerals and carbon dioxide in the water. Pond plants are classified into four groups: oxygenators, marginals, floaters and aquatic. Oxygenators such as buttercup and water violet supply lots of oxygen in the water. Marginals are ornamental pond plants and planted in pots or baskets in the edge of the ponds to provide space for fishes or frogs, e.g., Primula. Floaters like water hyacinth help in keeping algae at bay and also provide enough cover for tadpoles or small fish.

Bulbous plants are herbaceous perennial or biennial ornamental plants which produce fleshy storage organs including true bulbs, corms, tubers, rhizomes and tuberous roots. These underground organs have capacity to store moisture and nutrients are utilized by bulbous plants to survive winter or other adverse conditions such as summer drought and heat in a dormant state.

Cacti

Cacti belong to the family Cactaceae comprising of 130 genera and 2000 species and bear a complex organ, a cushion like structure spirally arranged over the stem called ‘areoles’ from which spines, hairs, flowers and shoots develop. In tribe, Pereskieae, the plants are leafy bushes or shrubby and characterized by areoles on the stem and by the typical flower borne in clusters, e.g. Maihuenia, Pereskia and Rhodocactus.

Rose
Rose is a perennial erect shrub, climber or trailing plant  belonging to the genus Rosa within the  family Rosaceae. The plants bear large and showy flowers of white, yellow, red, pink, orange and various shades. Most of the species are native to Asia.

Valuable Genetic Resources

Shrubs are group of plants having woody stems and multi-branching from the base of the plant. These plants are useful to build up the framework of the planting scheme for screens, ground covers, flowers and hedges. They vary in blooming time, colour, size, growth habit, fragrance as well as situations.

Herbaceous perennial flowers complete their life cycle in more than a year and usually bloom during a specific time period every year during the growing season. These flowers are hardy and herbaceous. They are popular in their dried form for beautiful and exotic dried flower arrangements. Besides, perennials are used as ground covers, mixed with annuals, grown as potted plants and used as accents or specimen plants. Some important perennial flowers are Baby’s Breath, Bells of Ireland, Blue Globe Thistle, Carnation Flowers, Daisy Flowers, Flax, Hibiscus, Hollyhock, Iris, Ladys Mantle,Larkspur, Lavender, Lily Flower, Monkshood, Pearl Everlasting, Rose Flowers, Statice, Sunflower, Yarrow.

Foliage or house plants are mostly those with attractive foliages or flowers and are able to survive and grow under indoor conditions. They are mostly used for interior decoration or interior plantscaping. Foliage plants of world’s importance include Aglaonema, Dieffenbachia, Dracena, Epidendrum, Ficus, Peperomia, Philodendron, Sansevieria, Syngonium, Schfflera, ferns, Anthurium, Codiaeum. Florida shares more than 55% in foliage industry.

India is bestowed with varied agroclimate ranging from mild tropical zones to alpine zones and congenial for several types of ornamental plants in different seasons. Worldwide China and India have large total areas under flower cultivation. Among top ten cut flowers, rose ranks the first position followed by spray chrysanthemum, tulip, lily, gerbera, cymbidium, freesia, chrysanthemum, anthurium, alstroemeria and carnation. In view of rapid changing global competition, diversification into lesser known potential new ornamental plants play key role in fetching premium prices. Most of the potential exotic ornamentals plants have been introduced from Australia, South Africa, Israel, New Zealand and Eastern USA. There are about more than 60 types of new ornamentals reported to be hold potential for commercial importance. All these newly introduced ornamental plants require the following stages of research and development.

Foodgrains are a fine example of diversity of nature with many varieties and varied features. They are storable food commodities and lend themselves to numerous processing manipulations. Nutritionally foodgrains are rich source of almost all known nutrients and several phyto-chemicals. The increasing incidence of metabolic diseases are attributed to unbalanced energy rich diets lacking in fiber and protective bioactive compounds such as micronutrients and phyto-chemicals (Prakash, 2013). Cereals along with pulse combinations constitute an important part of human diet in many parts of the world because of easy availability, low cost, long shelf life and nutritional balance. During recent past, India has made significant progress in improving the food security of its masses. The green revolution of 60’s helped the country in achieving the food security by improving the availability and access components (Kaul et al., 2016). However, surplus quantity of food produced is not uniformly distributed and the quality component is not addressed properly which has a direct impact on nutrition. In spite of surplus production of foodgrains still malnutrition persists. However, it can suitably be overcome by combining cereals with good quality pulses and other value addition techniques which will go long way in solving the problem of malnutrition. Even though country is producing large quantity of coarse grains particularly maize but its utilization for direct consumption is very low which is mainly due to poor quality of protein. Although maize contains higher proportion of protein (10-12 %), its quality is poor as compared to that of protein in rice due to presence of high concentration of alcohol soluble protein fraction ‘prolamine’ also known as ‘Zein’ in the endosperm. Zein is very low in some essential amino acids, mainly lysine and tryptophan which contribute to more than 50% of the total protein. On the other hand, very high amount of leucine and imbalanced proportion of isoleucine contribute to poor quality of protein in normal maize. To overcome such deficiencies, scientists developed Quality Protein Maize (QPM) where the quality of protein is not only higher than the common maize, but also significantly higher than that of other cereal grains. In the recent past QPM has got special distinction among the cereals due to presence of high amount of essential amino acids like lysine and tryptophan. QPM can be utilized for diversified purposes in food and nutritional security as infant food, health food, convenience food, specialty food and emergency ration. In India maize is consumed mainly in the form of boiled corn or roasted as pop corn. In order to increase the proportion of maize for direct consumption, several traditional food-processing and preparation methods can be used at household level to enhance the bioavailability of micronutrients in maize based diets. These methods include alkali cooking, thermal processing, mechanical processing, soaking, germination/ malting and fermentation. In countries like Central America and Africa, it is converted into food products by grinding, alkali processing, boiling, cooking and fermentation (Srilakshmi, 2008).

Value addition refers to the process of increasing the economic value of a product, service, or commodity through various means, such as: Processing: Transforming raw materials into a more refined or finished product.
Enhancement: Improving the quality, appearance, or functionality of a product.
Differentiation: Creating unique features, branding, or packaging to distinguish a product from others.
Innovation: Introducing new or improved products, services, or processes. Value addition in medicinal and aromatic plants (MAPs) is essential to enhance their economic value, quality, and marketability. Here are key reasons why value addition is necessary:
Enhanced economic value
Value addition increases the economic value of MAPs, benefiting farmers and stakeholders. Primary processing and value addition are crucial in this regard. For instance, drying, cleaning, grading, and packaging are essential steps in adding value to MAPs.
Improved quality and shelf life Value addition helps preserve the bioactive compounds and aroma of MAPs, extending their shelf life. Techniques such as drying, extraction, and storage in airtight containers are vital in maintaining the quality of MAPs.

1. Introduction

Medicinal plants are well known for their secondary metabolites which are alternatively called as active principles responsible for curing of diseases and disorders. India is a biodiversity rich country belongs within 12 mega diversity zones of the world and possesses four biodiversity hot spots, 8 phyto-geographic regions and 10 vegetation zones (Khandekar and Srivastava, 2014). This subcontinent holds 47000 different species of plants out of which 8000 plants are medicinal in nature (Hamilton, 2004, Owolabi et al., 2007). High rate of endemism and 426 habitats for specific species are the unique resource of the country (BSI, 2009; Khandekar and Srivastava, 2014). Still majority of the herbal raw materials are wildcrafted and hence habitat destruction and wildcrafting pose a serious problem to the natural population particularly where roots are the targeted plant part as the percentage of root yielding medicinal plants are higher in the subcontinent. Since these plants are purely industrial and not having alternative uses the commercial production is not flourishing at a higher pace. Still the production of medicinal and aromatic plants in India has reached 1031000 tonnes from 634000 hectares.

In the post-CBD regime with global developments in aspects of Plant Genetic Resources and Intellectual Property Rights, the outlook towards these lesser exploited species has been changed to bioprospecting from collection and documentation.Here lies the importance of value addition in medicinal plants. Value addition means a change of state of the produce which will give a manifold return than the additional investment. Value-added products can be obtained through processing of raw herb or crude drug which will improve its look and also increase its quality, longevity, efficacy and obviously the return.

In monetary terms, value-added’ per unit of the product is the margin between its selling price and cost of production. However, in the dairy and food industry, value addition refers to, extra, features of a product that are beyond the expectations of a consumer at little or no extra cost. In this context, the addition of value to milk can involve monetary value added to a liter of milk by turning it into milk products, enhancing the convenience of quality, shelf life, or health characteristics using processing and packaging interventions.

4.1. Conversion of Milk into Conventional Products

It is an age-old tradition to add value to milk by processing it into milk products. The primary aim was to increase the shelf life of milk that would otherwise be highly perishable. With inadequate facilities to preserve liquid milk fresh in the rural areas’ conversion of milk into a variety of milk products would be an ideal option to effectively preserve the huge quantities of milk procured during the flush season’ In the processing of milk products such as cream, butter, cheese and ghee, by-products such as skim milk, buttermilk, whey, and ghee residue are obtained’ Many of the dairy plants, particularly in India’ are usually confronted with the problem of by-products utilization, especially that of whey and ghee residue in an economical manner. Membrane separation processes have presented new possibilities for the production of newer intermediate products from dairy by-products that can be used for value addition in dairy and food industries.

Introduction

Mushrooms are fleshy spore-bearing fruiting bodies of fungi, produced above ground on soil or on their food sources. Total number of useful fungi having edible and medicinal values is over 2,300 species. Like green plants, they do not contain chlorophyll and as a result cannot manufacture their own food. In this respect, they are like animals because; they feed themselves by digesting other organic matter. They are a large heterogeneous group having various shapes, size, appearance and edibility.

The use of mushrooms as food is very old. People harvested mushrooms from the wild for thousands of years for food and medicine. The Egyptians regarded mushrooms as food for pharaohs. The Greeks and Romans described them as food for God and served only on festive occasions. The first professional growers of mushrooms were the Chinese. China is the major producer and consumer of both edible and medicinal mushrooms. As early as 1313, a document was published which described the cultivation method for Shiitake on wood logs. Even older is the cultivation of the wood ear mushroom (Auricularia spp) of which sources indicates that it was cultivated from the year 600 A.D. onwards. The white button mushroom, Agaricus bisporus, was domesticated in France.
