Organic cultivation is a deep rooted cultivation tradition, which had been practiced in many parts of the world, before the advent of the practice of use of chemicals.

After the green revolution there has been exponential usage of chemicals in agriculture, right from planting to harvesting. Chemicals are used in the form of nutrient inputs or for plant protection against pests, diseases, weeds and keeping deficiencies at bay. Nevertheless, after the awareness regarding the detrimental effect of chemicals on soil, climate and human health, there has been a lot of contemplation on substituting the chemicals with the organic alternatives. Growing crops using organic inputs is known as ‘organic cultivation’. Organic cultivation is a sustainable form of cultivation where a proper balance is maintained and management of plant nutrition, pests, weeds and diseases is done in a sustainable manner, keeping the soil microflora intact and active. It does not release any chemical gases in the atmosphere, does not make the soil acidic and the soil does not lose its structure and texture. Contrary to chemical farming, where over a time period, the soil quality, texture and structure is lost, in organic practices, the soil texture, quality and structure improves over time, the plants become strong and the quality of the produce is improved. Other than organic inputs, organic farming relies on some sustainable practices like using native germplasm, crop rotations with legumes, green manuring, mulching, inter cropping, mixed cropping, incorporation of farm and animal waste compost. These simple age old practices build to organic content in the soil and elevate the soil’s efficiency to make nutrients and water to the plants. The soil microflora and earthworms become biologically active, efficient and exponentially proliferate. The goal of organic cultivation is to get maximum produce from the soil in such a manner that the soil, air and water are clean and protected.

Plants grow in the open in nature, hence are subjected to biotic and abiotic stress.

Biotic stress is due to living components such as:

Insects and pests

Nematodes, mites, snails, slugs etc.

Vertebrates like rats, birds, jackal, bats etc.

The plant experiences biotic stress when root, stem, bark, shoots, leaves, buds, flowers and fruits are damaged by the influence and activity of biotic factors.

Biotic factors Diseases

Like the pests, diseases also cause stress to plants. Diseases are caused by fungus, bacteria and virus. Sometimes the exposed part of insect eaten plant part becomes the entry pathway for fungus, bacteria and virus.

India is bestowed with varied climatic conditions and a variety of horticultural crops are produced. It is estimated that 20-30% of the produce is lost before consumption because of various reasons including improper storage and this is where the need of processing for preservation arises. There are various ways of preserving the produce and various ways to process it.

Preservation is defined as methods of extending the shelf life of the produce in its original form or in a different usable form. The basic principle of preservation involves strategies which aim at reducing the spoilage. The horticulture produce is spoiled by microbial infection or infestation. Prevention of microbial damage can be achieved by keeping the produce away from microbes, by removing the microbes, obstructing the proliferation and by killing the microbes. Infestation in the harvested fruits may lead to other microbial infection and spoilage due to rotting.

Milk revolution with change in technology is gaining attention in India. Robotic milking reduces labour and increases efficiency irrespective of large dairy farms. A typical system requires a large camera- and spray-system robot. When activated to apply the disinfectant, the robot sends a six-foot- long pipe with the sprayer under the cow. These floor-mounted robots require expensive installation into the floor of the milking parlour, as well as fencing for employee protection.

15.1 Introduction

Mechanical draining has increased broad acknowledgment, especially in Western Europe, as an approach to lessen labor on dairy ranches, increment creation per cow, and improve the way of life of dairy ranch families draining 40 to 250 cows (De Koning, 2010). The developing ubiquity of this innovation is obvious in its fast pace. In 2009, the evaluated number of automated dairy ranches overall was 8,000 (De Koning, 2010). Only 6yr later, Barkema et al. (2015) proposed that this number had dramatically multiplied to 25,000 dairy ranches around the world. The level of groups utilizing this technology is most noteworthy in Scandinavian nations and the Netherlands (Barkema et al., 2015). Broad selection in these nations proposes in any event a proportion of accomplishment in helping dairy ranchers accomplish more noteworthy work productivity and a superior way of life, yet field experience recommends that wide variety exists in the measure of work spared and in the general fulfilment of early adopters.

Ridge gourd also known as ribbed gourd or angled gourd or silky gourd or angled loofah or vegetable gourd (Luffa acutangula (Roxb. L., 2n = 2x, family Cucurbitaceae, mostly monoecious and cross-pollinated but behaving like self-pollinated crop in term of no inbreeding depression) is not a crop of global importance; rather it is grown and consumed primarily in India and the adjoining countries which used to be part of greater India. In India, estimated area is 50,000 ha spread over almost entire country but the leading states are UP, Bihar, West Bengal, MP, Chhattisgarh, and Maharashtra, Karnataka, Tamil Nadu and north east hill region.

Origin and Domestication

Ridge gourd has similar origin as that of sponge gourd (refer to page 428).

Livestock population meet the protein requirement of humans in addition to meeting from plants. The food chain starts from fodder crops to animals and from animals to humans. In human physiology, digestion of plant protein is much easier than animal protein, but however the digestion depends on climate (temperate climate, sub-tropical climate, tropical climate etc.,) wherein human kind live. Similar to crops, there is strong interaction between livestock and meteorological weather elements (temperature, relative humidity, wind etc.). But detailed study has not been published elaborately in scientific journals in the past. The weather elements have greater influence on livestock productivity in terms of milk, meat, skin, wool etc., pest and disease infestation and their housing needs. In this chapter how weather elements influence shed management, pest and disease problem and animals’ productivity and are discussed. In majority of the Veterinary and Animal Science University in India, they have one division on animal climatology, wherein both research and extension aspects are being attended. However, in depth research is the need of the present decade, since little works have been done in the past on animal climatology.

Irrespective of weather elements, the heat stress due to the combination of temperature and relative humidity plays important role in affecting the productivity of animals. There is a range of thermal conditions within which animals are able to maintain a relatively stable body temperature by means of behavioral and physiological means. Heat stress results from the animal’s inability to dissipate sufficient heat to maintain homeothermy (Sejian et al., 2017). High ambient temperature, relative humidity and radiant energy compromise the ability of the animals to dissipate heat. As a result, there is an increase in body temperature, which in turn initiates compensatory and adaptive mechanisms to re-establish homeothermy and homeostasis. Homeostasis refers to the tendency to maintain a balanced or constant internal state that is optimal for functioning. Animals have a specific balanced or normal body temperature. When there is a problem with the internal functioning of animal body, this temperature may increase, signaling imbalance. As a result, body attempts to solve the problem and restore homeostasis for normal body temperature. These readjustments generally referred as adaptations and this is essential for survival of the animals.

1. Neutron activation analysis

This technique is used in qualitative and quantitative analysis. If an element present in a sample is to be identified by neutron activation analysis, the sample will be bombarded with slow neutrons or other charged particles and converted into radioisotope. It is one of the most sensitive and specific methods available for the determination of trace quantities of a wide range of elements. From the half life measurement, it is possible to identify the element from which the radioisotope has resulted. Also the quantity of element present in a given sample can be calculated by this technique.

Enzymes are biocatalysts that change the rate of reaction without being changed themselves. All (Most) enzymes are proteins but all proteins are not enzymes. Ribonuclease is the enzyme which is non- protein in nature.

Properties of Enzymes

Before beginning the actual work on the establishment of a Fruit and Vegetable Processing Industry the following points should be considered:

Availability and possibilities of obtaining Funds: Investment of own money or obtaining loans from banks etc.

The scale of industry (Large, Small, Cottage or Home): Has to be decided based on availability of raw material, funds availability, land, labour and other resources.

The location: The processing unit should be located near to the actual production site of raw material so that the transportation costs of high bulk raw materials is reduced. There is no fun or justification of establishing apple processing industry in Lucknow or Bangalore and mango processing industry in Shimla as the related raw materials would have to be transported through long distances.

Site: Site selected in the location should be sunny area free from dampness and sufficient space for waste disposal should be ensured.

Chicory (Cichorium intybus L. var. sativum D.C.) plant is the herbaceous, perennial plant and supposed to have descended from the wild chicory (wild succory, blue sailors) which is often seen along roadsides with its blue flowers. The leaves are used as salads in human diet and other different purposes. They were reported to be stomachic (Baumann 1982, Franke, 1981) and their juice was used against eye disease and poisoning. The infusion of chicory was believed to be good for the liver, kidney and stomach. Initially the wild plant was used but since approximately 300 B.C., the crop was cultivated for this purpose. Beverages, soups and sauces made of chicory were reported to be used in Italy and Belgium as early in 16^th century.

For the first time, the root of chicory was used as a substitute of coffee in 1690 in Holland followed by many other countries like Sweden, France, etc. During 1806 and 1813, the cultivation and use of roasted roots of chicory as coffee substitute spread over the whole European continent. In the 19^th century, the main centres of cultivation of chicory were North-East France, Belgium, England, Russia, Holland and Australia. Subsequently it was raised on large scale in Poland, Hungary, Germany, Switzerland and India. Presently over 20% of the World’s consumption takes place in Eastern Europe, especially in Poland (6%) followed by Russia, Hungary, Romania, Czechoslovakia and East Germany. Twelve percent is reported to be consumed in South Africa, 9% in India and 2% in the United States (Clark and Macrae, 1987).

Food is a major determinant of health, nutritional status and productivity of the population. It is, therefore, essential that the food we consume is wholesome and safe. Unsafe food can lead to a large number of food-borne diseases. It is necessary that the food available is safe, hygienic, wholesome and its quality must be assured. Quality of foods can be defined as the ‘composite’ of those ‘characteristics’ that differentiate individuals units of a product and have significance in determining the degree of acceptability of that unit by the buyer. In general, the quality control is the maintenance of quality at levels and tolerance acceptable to the buyer, minimizing the cost for the vender. But, from the scientific angle the overall quality refer to technical, physical, chemical, microbiological, nutritional and sensory parameters to achieve the wholesome food. These quality factors depend on the specific attributes such as sensory properties, based on flavour, colour, aroma, taste, texture, quantitative properties viz. percentage of sugar, protein, fibre etc and hidden attributes like peroxide, free fatty acids, enzymes etc. Though quality attributes are many, not all need to be considered for a particular product. It is imported to determine how far relatively the factor is in relation to the total quality of the product.

Hence, the quality attributes of a particular is based on the composition of the product, expected deteriorate reaction, packaging used, shelf required and the type of the consumer i.e., deployed in terrain conditions or in peaceful situation. With the ultimate goal of protecting the consumer, quality standardization systems have come into force for regulating the gamut of operations in food manufacture. In a broader sense, food laws and Regulation cover the related acts affecting the marketing, production, labeling, food additives used, dietary supplements, enforcement of General Manufacturing Practice (GMP), Hazard analysis and critical Control Point (HACCP), federal laws and regulations, factory inspections and important-export inspections.

The food is considered as one of the essential for the maintenance of life. Manufacturing of the food product is not enough form the food industry. It is necessary that the food available is safe, hygienic; wholesomeness and its quality must be assured. The food industry is an important segment of industries in India and has its own peculiarities unlike other industries. Food processing industry has been recognized by government as a major sector of growth. It must be free from harmful additives, microbes and remain so for a period, it is intended to be consumed. Therefore, the methods employed in quality and food safety assurance programme within the food industry will vary considerably in accuracy and sophistication according to the type of process and size and nature of resources available. Since the international market has become demanding in terms of quality, safety and delivery, installation of Hazard Analysis Critical Control Point (HACCP) in food industry would provide a competitive edge to food supplies in the international market. Food control refers to all activities carried out to ensure the quality, safety and honest presentation of the food at all stages from primary production through processing and storage, to marketing and consumption. The term has been used to describe a total national effort involving an integrated approach between government and all segment and sectors of the food industry. Food control is linked to improvement in the health of the population, potential of a country’s economic development and reduction of spoilage and food losses.

A wide variety of quality determinants is employed, including size, colour, maturity and extent of blemishes. Quality is a measure of the degree of excellence or degree of acceptability by the consumer. The marketing of fresh fruit and vegetables is aimed eventually ay appealing to the consumer for whom tradition plays a major role in determining the acceptability of a food item. The eating habits of people are conservative. The increase of direct market from producer to supermarket chains is leading to the imposition of standards to predetermined specification by the supermarkets. Important factors in quality for the consumers are: appearance, including size, colour, shape, condition and absence of defects, texture, flavour and nutritional value. Quality is the ultimate criterion of the desirability of any food product to the consumer. The overall quality of food depends on the nutritional and other hidden attributes. Quality of foods can be defined as the ‘composite’ of the ‘characteristics’ that differentiate individual units of a product and have significance in determining the degree of acceptability of that unit by the buyer.

Radiant energy (Q_e, J): The transfer of energy of radiation.

Radiation frost: Heat radiated from surface of soil, trees, and any other solid particles to reduce the temperature low enough to cause frost conditions. Solid particles lose heat more rapidly than air, reducing the surface temperature. Eventually the air at low levels becomes cool and heavy compared to air at higher elevations. Occurs more readily on cloudless nights when there is no barrier for retaining the heat (i.e., a barrier that radiates the heat back to earth).

Radiation: The emission and propagation of electromagnetic waves or particles through space or matter.

Radical (Free Radical): An atom or a group of atoms with an unpaired electron which can exist independently for short period during the course of chemical reaction.

Radicle: Embryonic root of seed plants.

There are great variations in the life cycles of fungi. Raper (1954, 1966b) recognizes seven basic types.

5.1 Asexual cycle

In which sexual reproduction apparently lacks and diploidy is restricted to somatic diploids. The entire groups known as Fungi Imperfecti and numerous other species which clearly belong to various groups of the perfect fungi such as Penicillium notatum have this life cycle. Certain benefits of sexuality are provided here in many of the sterile forms by para sexual recombination.

Agriculture has been the base of human livelihood since ancient time when the man started planting of seeds of some edible plants now called Agricultural crops. Domestication of food plants and animals was started with the development of human civilization. Thus agriculture can be explained as science and technology of growing food crops and rearing of animals. Still in several countries of the world, most of population is based on agriculture for their livelihood particularly in rural areas of that country. According to Williams and Haq (2002) there are over 7000 species of plants that can be used for food. The edible plants species grown for food are called agricultural crops. The crops grown in garden are known as garden cops or Horticulture crops. Horticulture is a branch of agriculture, which deals with intensive cultivation of garden crops such as fruits, vegetables, f lowers, ornamental plants, plantation crops, spices, medicinal and aromatic plants, and mushroom. It also deals with post-harvest technology of horticultural crops. Processing and Preservation of fruits and vegetables is a part of Post-harvest Technology of horticultural crops which deals with methods of processing and preservation of these crops to extend the shelf life of fruits and vegetables after harvesting.

All horticultural crops have their own importance in our society. Fruits, vegetables and spices are major ingredients of our meal. Spices add taste and flavor to our food and also have high medicinal values. Flowers and ornamental plants are used for decoration of environment and landscape. Aromatic and plantation crops have become industrial crops. Mushroom growing is a great enterprise. Among these crops fruits and vegetables are major crops and have been considered presently as highly economical and important food crops. There are 1200 crop species are used for vegetable purpose in the world (Hazra and Som, 2006). Fruits and vegetables are richest and cheapest source of all essential nutrients (carbohydrates, fat, protein, vitamins and minerals) required by our body for proper functioning of body organs and maintaining good health. Besides these nutrients they also supply water and fibers to our body which play vital roles in our body. Fruits and vegetables have important place in our daily diet and based on survey made by experts FAO WHO (2003) has recommended 400 g/capita/day of fruit and vegetables (fruits -100 g/capita/day and vegetables -300 g/capita/day) to be consumed for good health and prevent chronic diseases. Therefore, the demand of these food commodities has increased in the modern society due to increased awareness of the nutritional importance of fruits and vegetables. So that people must be aware that what part of fruit and vegetable is to be consumed?

INTRODUCTION

Electronic books are one way to enhance the digital library with global 24X7 access to authoritative information, and they enable users access specific research material easily, quickly and effectively. Library users are also able to remotely search, locate and check out e-books from the libraries using online public access catalogs (OPACS). As with any new opportunity new challenges emerge and utilizing the internet to deliver book content is no exception. Integrating e-books into the digital library has created challenges and opportunities for LIS professionals; publishers and e-books providers.

E-BOOKS

An e-book is based both on emulating the basic characteristics of traditional books in an electronic format, as well as leveraging internet technology to make access to e-books easy and efficient to use.

Electronic books offer creative possibilities for extending access as well as changing learning behavior and academic research. Content can always be accessible regardless of time or place, to be read on Pc or on portable book readers, books need never go out of print and new editions can be easily created. One can carry several times at once on a portable reader and over time build a personal library, features such as full text searching, changeable font size, mark up, citation creation and note taking will enhance usability. Print text can be integrated with multi dimensional object, sound to create a whole new kind of monographic work.

INTRODUCTION

Libraries have become Library and Information Centers (LIC) and Knowledge Resource Centers (KRC). Many LICs and KRCs have stepped forward towards establishing Digital Libraries and Digital Repositories. These wings require the professionals with adequate qualifications and should have good command over the latest technologies. The trained candidates prior to their recruitment may immediately take up a project with a challenge. The professionals who are in service may enhance their skills through sponsorships to long term / short term programs.

In the present era, LIS is treated as multi-disciplinary subject and has integration with all newly emerging subjects. The other side, the LIS departments in the Universities have to respond properly (towards requirement) in incorporating suitable latest topics in their curricula and implement it very strictly. The research activity in LIS field in the country has to grow suitably along with the developed countries. In Andhra Pradesh, similar response is needed from the Government in providing and releasing funds to the state universities to start LIS departments. The preference has to be given by the State Government to LIS research in public libraries in proportionate with Science, Humanities and Social Science libraries. In future, it is expected that the LIS research should lead.

Introduction

Meat has become an integral part of human food to meet the essential nutrients, like proteins. For a balanced diet, a good biological availability of meat is preferred in the modern day era. The per capita consumption of meat in India is only 14g per day as against the actual requirement of 125g. Non availability of quality meat and its exorbitant prices have restricted meat consumption. Increasing the meat production through intensive rearing of various meat animals will help to meet the ever growing demand of a balanced human diet. In the modern era and educational status social taboos are also getting relegated with need of quality proteins.

The very important role of pigs in human life is control of environmental pollution by scavenging the biological waste. Pig converts biological waste material to quality proteins in the form of pork. Pigs have a rapid growth rate, high reproductive efficacy, require comparatively less space, and can be reared on small scale in backyards or as commercial units.

The lymphatic system is an extensive drainage system that returns water and proteins from various tissues back to the blood stream. The system consists of
a network of very fine vessels or tubes called lymphatics that drain lymph from all over the body, and lymphnodes. Lymphatics are found in every part of the
body except the central nervous system.

Causes: Dietary causes like hypovitaminosis A, nutritional deficiency of vitamin B complex, linoleic acid. Iodine poisoning. Parasitic causes like flea, lice, mange infestation, ring worm.

Abstract

Livestock remain a lifeline for many of the world’s poorest people. Cattle, goats, sheep, pigs, chickens and other farm animals form part of the livelihood portfolios of an estimated 70 per cent of the world’s rural poor women and men. For many smallholder farmers, livestock are essentially four-legged bank accounts, allowing hundreds of millions of unbanked poor to build assets and to insure themselves against shocks such crop failures, accidents and illnesses. Such assets and insurance are particularly important to women, who remain the backbone of global smallholder agriculture and who are one of the best hopes for ensuring future global food security. Across the world’s varied livestock production systems, women are main actors in poultry, small ruminant and micro livestock production as well as in dairying including the processing and marketing of milk and milk products. But women are often still excluded from household decision-making processes, especially regarding the disposal of animals and animal products. This lack of female control over livestock assets and income impinges on family welfare as well as economic growth.

Key words: Economic growth, Livestock assets, Insurance, Women.

Introduction

Agriculture and allied sectors contributing significantly to rural employment generation. It also contributes almost 18% of GVA (Gross Value Added) in Indian Economy at current prices (Economic Survey of India 2016-17). It remains sustaining livelihood security with nutritional security and help in social transformation of the country. Second half of 20th century witnessed the change of traditional and subsistence Indian agriculture into a commercial activity. Green revolution of sixties paved the way for entry of agribusiness companies selling seeds, fertilizers, pesticides and farm machineries. Agriculture today faces many challenges which include globalization and market liberalization, food price crises, natural resource depletion, climate change, rapid urbanization, changing production and consumption patterns, demographic changes etc. Market driven agriculture production is need of the hour since marketing has become a challenge for small farmers. Agri- preneurship development can be key in this scenario.

Introduction

Rural development focuses on development of rural man, woman and all things. Rural development influences the growth of economy in rural areas. Rural development mainly depends on agriculture. This agriculture reduces hunger in rural areas and increases food security. Bondad-Reantaso et al., (2009) showed for rural development aquaculture act as a indicator. Brummett and Williams (2000) showed rural development of aquaculture in Africa.

Role of poverty alleviation by aquaculture

(a) Aquaculture creates employment in rural area

(b) Aquaculture gives nutrition to infants and women

(c) Vale of aquaculture is comparatively high.

(d) Rural people may income by selling the fish seed.

(e) Landless people can cage culture, mollusks culture in very short place.

Nursery is one of the important components of horticultural crop production. Nursery is place where young crop plants are raised under intensive care for later transplanting to the field. Nurseries may be classified as follows. On the basis of the irrigation facilities, the nurseries are dry or wet nurseries.

1. Dry Nurseries: Generally such types of nurseries are observed in forestry. It is maintained without any irrigation or artificial watering. The rab nurseries of Western Maharashtra, Karnataka and Gujarat come under this category. The rab or semi-rab nurseries are made in the plantation areas on small well-burnt patches of land usually 0.01 to 0.05 ha mainly for supplying teak stumps. The seeds are sown in lines 45 cm apart just before the onset of monsoon. Normally no elaborate beds are made, no fencing is made and no irrigation is provided as compared to other nurseries.

Good governance is crucial for the effective functioning and development of any country, including India. To ensure good governance, several steps have been undertaken in India. Here is an introduction to some of these steps;

1. Strengthening the Democratic Decentralization

The 73^rd and 74^th Amendments to the Constitution of India are pivotal in strengthening democratic decentralization in the country. These amendments, passed in 1992, provide constitutional recognition and support for local self-governance in rural and urban areas, respectively. The 73^rd and 74^th Amendments establish Panchayats (rural local bodies) and Municipalities (urban local bodies) as institutions of self-government. They empower these local bodies with the authority to plan and implement economic development programs, social justice initiatives, and the provision of essential services within their jurisdictions.

33.1 Introduction

World fisheries face the threats of overfishing and climate change that have resulted in the extinction of genetically unique stocks and loss of genetic diversity. Genomics has brought new tools that can help address fundamental questions in fisheries management such as stock identification, population structure, and adaptive response to environmental change (Bernatchez et al, 2017).

43.1 Introduction

Game fish (also known as sport fish or quarry) are freshwater or saltwater fish that are pursued by recreational anglers or fished with a rod and line from clear running water (Hora 1943). Some game fish (such as salmon and tuna) are commercially targeted. In other words, game fish are fish caught for sport or subsistence. Trophy f ish are game fish that are larger and heavier than the average for the species.

A problem in the 1970s was the emergence of pathogen strains that were resistant to chemical . Concerns from the public about the effects of agricultural pesticides generally on human health and the environment have grown in the 1980s . A number of pesticides have been deregistered, subject to limitations, or taken off the market as a consequence of this issue.

Because of perceptions rather than actual facts, the use of agricultural pesticides frequently raises serious public concerns. Concerns include the potential for human and domestic animal poisoning, contamination of livestock products, harmful effects on beneficial microorganisms like pest predators and pollinating bees, dangerous residue levels in foods made from sprayed crops, ecological disruption at the level of microorganisms, and the potential for water contamination with subsequent fish loss and residue buildup in groundwater.

By reducing losses from pests and diseases, the agrochemicals sector contributes significantly to raising agricultural output. In order to meet the challenges of feeding India’s growing population and bringing foreign exchange into the Indian exchequer through the export of high-quality agricultural products worldwide, the prudent use of crop protection chemicals promotes sustainable farm management and offers socioeconomic benefits. Nonetheless, most of the marginalised farmers who are forced to practise subsistence farming are able to produce only enough food to support their family.

Farmers Must Always Get Genuine Products

Since its start, the pesticide industry has supported crop productivity and our agricultural economy. It was crucial in bringing about the Green Revolution. By protecting plants from pests and diseases, pesticides let India’s high yielding types and hybrids reach their full potential for productivity. The Integrated Pest Management (IPM) Programme of the Government of India, state governments, and state agricultural institutes is not complete without the use of pesticides. Farmers will receive value-added solutions from the industry via on-farm demonstrations and on-the-spot knowledge-sharing. The emphasis is on creating plans using chemicals for plant protection and attending to the farmers’ urgent requirements.

Concretions

Concretions are solid, compact mass of material, endogenous or exogenous in origin, found in tissues, body cavities, ducts or in hollow organs. Concretions are stone-like bodies commonly occur in urinary system, gall bladder and gastrointestinal tract. Concretions of endogenous origin are known as calculi while those formed from exogenous material are known as piliconcretion (Hair), phytoconcretion (plant fibres) and polyconcretion (polythenes).

Calculi

Calculi are formed due to deposition of salts around the nucleus/nidus consisting of either fibrin, mucus, desquamated epithelial cells or clumps of bacteria. Due to the gradual and repeated precipitation of salts, calculi become laminated. In the process of calculi formation, the inner structural arrangement gets shrink, producing a rough superficial surface. Calculi formation is more common in urinary system and in gall bladder of man and animals; however, they may also occur in salivary gland, pancreas and intestines.

Introduction

Chestnut (Castanea sativa Mill.) belongs to the family Fagaceae and is a deciduous tree. It is also known as sweet chestnut and has a chromosome number of 2n=24. Chestnuts have been used for centuries for various purposes such as food, timber, and medicine. They are an important source of carbohydrates and contain several nutrients such as vitamins, minerals, and fiber (Laribi et al., 2020). In India, chestnuts are mainly grown in the hilly regions of Jammu and Kashmir, Himachal Pradesh, and Uttarakhand.

Origin and distribution

Chestnut is believed to have originated in the Mediterranean region and was later introduced to other parts of the world. It is widely grown in Europe, Asia, and North America. In India, chestnuts were introduced by the British in the 19th century and were mainly grown as an ornamental tree. It was only after Independence that chestnuts were recognized as a potential crop for the hilly regions of the country (Bhat et al., 2016).

The major raspberry-growing states in India are Himachal Pradesh and Jammu and Kashmir.

34.1. Aim

To conduct cut out analysis of canned fruits and vegetable products.

34.2. Theory

Cut out examination of canned products is conducted to evaluate the product whether confirming to FSSAI standards or not. Canned fruit and vegetables are evaluated for presence of vacuum or pressure in the can, drained weight, total soluble solids, presence or absence of preservative, internal condition of can product contents and presence or absence of fermentation for ensuring microbiological safety.
