Abstract

Consumer now-a-days relies on manufacturing and processing standards, particularly to know what ingredients are present, due to dietary, nutritional requirements, or medical conditions (e.g., diabetes orallergies). Modified PCR and combination of PCR with other analytical tools have been successfully used for analysis of various parameters related to functional foods such as detection and quantification of beneficial as well as food borne pathogenic microorganisms, food allergens, raw material source, bioactive compounds, genetically modified foods. Multiplex PCR method has been found to be an efficient tool for simple, rapid, and reliable identification of Lactobacillus and Bifidobacterium in probiotic products. Food allergens like gluten, peanut, hazelnut etc. could be easily detected in foods using PCR, even if present in small quantities. BOX-PCR and PCR-DGGE analysis have been used for identification of bacterial diversity of a naturally fermented functional food (Enzyme). HPLC combined with real time -PCR were successfully used to quantify and analyse compounds of secondary metabolites like phenylpropanoid amides, which represent an important class of nutraceutical having strong antioxidant and chemotherapeutic effects in various transgenic tomato tissues. Detection of active compounds in natural plant products were successfully achieved using PCR techniques. In general PCR have gained more importance as it has high sensitivity, improved precision, wide dynamic range for quantification, genotype based and is quick method of detection and quality control of foods than traditional culture based methods.

Introduction

Biointensive integrated pest management (BIPM) is essentially a component of integrated pest management which helps to reduce the dependence on chemical pesticides thereby preventing ecological deterioration. The major elements of this approach includes many factors viz. host plant resistance, use of beneficial organism, agronomic practices, bio pesticides, parasitoids, predators, plant exudates etc. It also includes all other conventional non-chemical methods of pest control like use of botanical insecticides preferably plant based insecticides like Azadirachtin from Neem (Azadirachta indica), Rotenone from Derris chinensis and Derris elliptica, Nicotine from Tobacco (Nicotiana tabacum), Juvocimene 1 or 2 and Ocimin from Ocimum sanctum, Atropine from Datura stramonium, Annonine and Squamocin from Annona squamosa etc.

The key genetic parameters available with the animal breeder to attain improvement are heritability, repeatability and genetic correlation. This chapter will mainly deal with the theoretical considerations of these parameters.

The goal of an animal breeder is to bring about permanent improvement in different economic traits, either individually (univariate) or simultaneously in multiple traits (multitrait). The phenotypic value available from the animal is a combination of genotypic value and environmental deviation. By permanent improvement in a trait, we mean the improvement in genotypic value, which could be carried over to future generations. The environmental deviations are spatially and temporally specific, and thus will not be the same over generations. The genotypic value, itself is made up of additive effect, dominance deviation and interaction deviation. The additive effect is a value of genes (the sum of the average effect of genes) and hence is more important for the breeder as only the genes are passed on to the next generation.

Pineapple is a wonderful tropical fruit having exceptional juiciness, vibrant tropical flavour and immense health benefits. Pineapple contains considerable calcium, potassium, fibre, and vitamin C. It is low in fat and cholesterol. Vitamin C is the body’s primary water soluble antioxidant, against free radicals that attack and damage normal cells. It is also a good source of vitamin B1, vitamin B6, copper and dietary fibre. Pineapple is a digestive aid and a natural Anti-Inflammatory fruit. A group of sulfur-containing proteolytic (protein digesting) enzyme (bromelain) in pineapple aids digestion. Fresh pineapples are rich in bromelain used for tenderising meat. Bromelain has demonstrated significant anti-inflammatory effects, reducing swelling in inflammatory conditions such as acute sinusitis, sore throat, arthritis and gout and speedy recovery from injuries and surgery. Pineapple enzymes have been used with success to treat rheumatoid arthritis and to speed tissue repair as a result of injuries, diabetic ulcers and general surgery. Pineapple reduces blood clotting and helps remove plaque from arterial walls. Studies suggest that pineapple enzymes may improve circulation in those with narrowed arteries, such as angina sufferers. Pineapples are used to help cure bronchitis and throat infections. It is efficient in the treatment of arterioscleroses and anaemia. Pineapple is an excellent cerebral toner; it combats loss of memory, sadness and melancholy. Pineapple fruits are primarily used in three segments, namely, fresh fruit, canning and juice concentrate with characteristic requirements of size, shape, colour, aroma and flavour.

This chapter portrays flooding as a geohazard that can be managed with ease through simple and effective measures. Flooding is a recurrent geohazard that affects vast lands in India and elsewhere. Unlike many other geohazards, flooding event and probable area to be affected could be predicted with fairly accurate levels and hence, proper safety measures could be taken easily. However, as flash floods could not be predicted and the nature of flooding hazard that it brings in added danger of health hazard, crop damage and cutting off of supply and communication networks, flooding is as serious threat as any other geohazard. Scientifically designed urbanization and flood control measures are suggested for minimizing the potential impacts of flooding.

INTRODUCTION

Flooding is defined as a temporary submergence of a large area (that normally remains dry) under water by overflowing rivers and reservoirs as a result of heavy rains, high winds, cyclones, storm surges, tsunami, melting of snow or dam burst (Arya et al. 2005). The term “temporary submergence” denotes a time period ranging from few hours to about few months depending on type and location of flooding. Although flooding is a natural phenomenon that plays a major role in replenishing wetlands, recharging groundwater and supports agriculture, extreme demands on natural resources due to population growth, people and their property move closer to water bodies

Introduction

The present trend in the search for new drugs is to look at natural sources, which are safer for humans and ecofriendly. Of late there has been increased awareness about the detrimental effects of synthetic food supplements, food additives and drugs, and the search for natural alternatives in plants has intensified. In this regard, horticultural crops are particularly appealing since they are not only edible, but also have diverse nutraceutical effects. Nutraceuticals (often referred to as phytochemicals or functional foods) are natural, bioactive chemical compounds that have health promoting, disease preventing or medicinal properties (http://foodsci.rutgers.edu),such as antioxidant, anti-inflammatory, hypoglycemic, hypolipidemic, antimicrobial effects, to name just a few. Most of these properties are attributed to the secondary metabolites present in plants, various phytochemicals including flavonoids, terpenoid, lignans, sulfides, polyphenolics, carotenoids, coumarins, saponins, plant sterols, curcumins, phthalides etc. The medicinal value of our horticultural crops is not a new knowledge, it has been exploited by the traditional systems of medicines like Ayurveda, folklore medicines and ‘kitchen remedies’ since time immemorial.

A functional food is similar in appearance to, or may be, a conventional food that is consumed as part of a usual diet, and is demonstrated to have physiological benefits and/or reduce the risk of chronic disease beyond basic nutritional functions, i.e. they contain bioactive compound.

A nutraceutical is a product isolated or purified from foods that is generally sold in medicinal forms not usually associated with foods. A nutraceutical is demonstrated to have a physiological benefit or provide protection against chronic disease.

India is the second largest producer of vegetable crops with a total production of 146.5 million tonnes (2010-11). More than 60 vegetable crops belonging to, Solanacious, Cucurbitaceous, Leguminous, Cruciferous (cole crops), root crops and leafy vegetables are grown in tropical, subtropical and temperate regions. The demand of vegetables will be 225 million tonnes by 2020 and 350 million tonnes by 2030. A larger quantity of quality seed of vegetable crops will be required in order to achieve the demands of vegetables. The limiting factors which reduce seed yield under open field condition are biotic and abiotic stresses, requirement of isolation distance and generation system of seed multiplication etc. These problems can be effectively managed when we go for seed production under protected structures.

In Article IX of IPPC, it is stated that RPPOs shall

• Function as coordinating bodies in the areas covered by the IPPC (including information sharing)
• Cooperate with the IPPC Secretariat in achieving the objectives of the IPPC (including the development of ISPMs)
• Cooperate with other RPPOs and participate in the regular Technical Consultations for RPPOs that are convened by the IPPC Secretariat

At present, there are 10 RPPOs covering the different regions of the world. Each RPPO has its own independent statutes and conducts its own regional cooperation programme. RPPOs produce regional standards for their members. They cooperate with each other and with the IPPC Secretariat. In particular, they meet in Technical Consultations to promote the development and use of relevant ISPMs and to encourage inter-regional cooperation on phytosanitary measures for controlling quarantine pests and preventing their introduction and spread.

India is floristically extremely rich with about 33 per cent of its botanical wealth (over 15,000 species of higher plants) being endemic. There are about 141 endemic genera distributed over 47 families (Nayar, 1980) the 4,900 endemic species, a large number are localised in the Himalayas (about 2,532 species), compared with the peninsular tract (1,788 species), and the Andaman and Nicobar Islands (185 species). Indian region is a major centre of domestication and diversity of crop plants (Zeven and de Wet, 1982; Arora, 1991). About 33 per cent of the cultivated plant species have theirorigin in this region (Damania, 2002). The Indian sub continent is a centre of domestication and diversification of several economically useful wild plant species comprising about 3,000 plants of edible value, 4,000 species having known reputed medicinal value, 700 plants of traditional and social significance, 500 fibre-yielding species, 400 fodder plants, 40 plants having insectivorous uses, 300 gum and dye yielding plants and 100 aromatic and essential oil-yielding species (Arora, 1991).

Introduction

Food safety and quality assumes paramount significance in any food industry. Globalization has driven both the food and agricultural firms to adopt systems that functions in a way to interlink food standards and international trade so as to achieve superior food quality and safety. Food industries follow several regional and international food safety procedures to procure certification from the government and other agencies in order to survive in both domestic and international markets (Ryan, 2014). The essential components in the food safety include handling, preparation and storing of the food products to ensure the food quality and to avoid food-borne diseases. The unwanted substances in a food product included by an accident is known as contaminants and the unwanted substance added to the food product to reduce the cost or to improve the other properties are known as adulterants. Contaminants and adulterants may lead to pathogens and toxins that pose serious concerns over the health of the consumer (Jha, 2016). The adulterants and contaminants are classified as physical adulterants and contaminants, chemical adulterants and residues, microbiological and pathogenic contaminants and toxins.

Hazards in food can be categorized into physical, chemical and biological.

Physical Hazards: Physical hazards are foreign organic or inorganic objects or extraneous materials in the food products. Hard and sharp physical hazards are of particular concern. Examples of physical hazards are broken glass, plastics, metal pieces, wood pieces, stones etc.

Stratified Sampling (Meaning and Concept)

The word ‘stratify’ comes from the Latin word, meaning ‘to make layers’, thus in stratified sampling the whole population is considered to be classified into some mutually exclusive layers or subgroups or classes also called strata. The strata do not overlap and they constitute the whole population.

Why the population is considered to be divided into different strata (or layers or subgroups or classes)?

Pest

A pest is any animal or plant detrimental to crops, livestock and forestry. The term is also used of organisms that cause a nuisance, such as in the home. An older usage is of a deadly epidemic disease, specifically plague. In its broadest sense, a pest is a competitor of humanity, means disease causing microbes, plant devouring insects, macro-fauna like rats and moles, weeds, off type plants and even human beings are pests in perspective of plants.

IPM

IPM is a pest management system that in the context of associated environment and population dynamics, utilizes all the appropriate techniques to minimize the pest population levels below those causing economic injury. Integrated Pest Management (IPM) includes cultural Practices, Host Plant Residence, Mechanical control, Biological control, Use of Bio-pesticides, botanicals and Chemical control.

To learn the nutritional importance of seafood and their processing; rigor mortis and their role in seafood quality, intrinsic and extrinsic factors affecting seafood quality and sensory quality assessment methods.

1.1. Importance of Seafood

Seafood has been traditionally a part of diet in many parts of the world. In some countries like India, it constitutes the main supply of animal protein among coastal population. Seafood is a low-calorie food and easily digestible compared to other protein-rich meat and poultry products and hence, it is a good choice for elderly persons to obtain their daily protein requirements. Seafood has high-quality quality enriched with all the essential amino acids required for human health. It provides about 1/3rd of the average recommended daily allowance (RDA) of protein.

Abstract: The Santhals of Orissa raise Teak (Tectona grandis) and Cashew nut(Anacardium occidentale) on their marginal and wastelands randomly to meet their contingencies. Upland is utilized for short duration upland paddy cultivation for food. The sporadically grown Teak and Cashew is used as insurance crops for meeting the high risk of dry land paddy. This work is unique and innovative as it was carried out in participatory mode on the pooled land from 14 Santhal households.  It is a maiden attempt in Orissa to develop Agroforestry models using forestry (teak) and horticulture (cashewnut) interventions into the paddy cultivation on uplands by Santhals without much alteration in their age old traditional agricultural practice. The basic objective of this research is to develop most profitable Agroforestry system(s) to provide best land use option for the risk prone dry land paddy cultivation to improve the farmers’ economy with simultaneous natural resource conservation.
 
The Agroforestry models Silvi-horticulture (Teak and Cashewnut)  Agri-silviculture (Paddy and Teak), Agri-horticulture (Paddy and Cashewnut) and Agri-silvi-horticulture (Teak, Cashew nut and Paddy) were developed by the Santhal tribe in Mayurbhanj District of Orissa. The inputs and planting material were sponsored by a leading NGO- Gamin Vikas Trust, which is working on poverty alleviation through Natural Resource Management of the State.

The concept of entrepreneurship has a wide range of meanings. On one extreme, an entrepreneur is a person of very high aptitude who pioneers change, possessing characteristics found in only a very small fraction of the population. On the other extreme of definitions, anyone who wants to work for himself or herself is considered to be an entrepreneur. The word entrepreneur originates from the French word, entreprendre, which means “to undertake.” In a business context, it means to start a business. The Merriarn-Webster Dictionary presents the definition of an entrepreneur as one who organizes, manages, and assumes the risks of a business or enterprise.

Many research studies have contributed to the literature on characteristics of entrepreneurs. Austrian economist Joseph Schumpeter’s definition of entrepreneurship placed an emphasis on innovation, such as new products, new production methods, new markets and new forms of organization. Wealth is created when such innovation results in new demand. From this viewpoint, one can define the function of the entrepreneur as one of combining various input factors in an innovative manner to generate value to the customer with the hope that this value will exceed the cost of the input factors, thus generating superior returns that result in the creation of wealth. From an economist’s point of view, an entrepreneur is one who brings resources, labour, materials and other assets into combinations that make their value greater than before.

Mutation: Natural genetic variation has exhausted. Genetic variation can be induced by mutations or changes in the DNA sequences of the plants.

Additional Tools for Plant Improvement

Increase in yield with no additional lands available for cultivation depends on development of high yielding varieties suitable for marginal cultivation.

• Food security

• Nutritional security

Need for additional tools to increase efficiency of breeding methods for genetic enhancement and propagation.

• Genomics

Genomics – Definition

Genomics - Study of an organism's entire genome / full genetic complement of an organism.

1. Introduction

Libraries serve as global repositories of knowledge, like to giant treasure boxes. But librarians are faced with a lot of work as more and more things become digital. Electronic Resource Management Systems (ERMS) can help with that (Prajapati, 2016). These are incredibly useful tools that have completely transformed the way libraries handle digital content. The main goal of ERMS is to simplify librarians' lives. They support the acquisition of fresh digital materials, manage subscriptions and licenses, and even provide online resource locators (Anbu et al., 2013). They essentially act as librarians' superhero sidekicks, ensuring that everything works seamlessly in the digital realm. ERMS play a major role in keeping everything organized. They support librarians in maintaining inventory, determining who can use what, and determining when to update it (Mangrum & Ellen Pozzebon, 2012). Libraries are able to ensure that everyone has access to what they need while adhering to all access regulations in this way. However, ERMS aren't limited to library use. They're also excellent for any library user. By making it simple to locate what you're looking for in the library's digital collection, ERMS addresses that. They keep everything organized so you can quickly get to the essentials (Prajapati, 2016).The key component that keeps contemporary libraries running well is ERMS. They make it easier for librarians to handle electronic resources and for users like you and me to find what we're looking for. Thus, keep in mind that ERMS are the unsung heroes who make it all happen the next time you're navigating your library's digital world.
