5.1 Introduction

Food is the basic requirement of every living being and it provides physical, mental as well as emotional satisfaction. Globally, there are many food enterprises which provide this basic necessity across the nations irrespective of nature of origin and climatic condition. Food companies are required to provide products at certain quality parameters so as to maintain the uniformity in the food system. Hence, food quality can be defined as a total of traits and criteria which characterize food as regard to its nutritional value, sensory value, convenience as well as the safety for a consumer’s health. Food quality is the quality characteristics of food that is acceptable to consumers. This includes external factors as appearance (size, shape, colour, gloss and consistency), texture, and flavor; factors such as grade standards and internal (chemical, physical, microbial). Due to the various food risks, all over the world the quality regulation authorities have intensified the efforts to improve food quality. Some of the quality related systems are obligatory by law while other is voluntary which are to be implemented by the various food chain members.

Many companies are forced to improve safety and quality of their products by implementing the quality and safety assurance and management system because of growing consumers’ expectations and concerns as regards food quality and safety.

In order to attain maximum profit and decrease the flaws, a new system was developed and followed by various companies all over the world. This new system is known as Six Sigma. The application of this system has the capability to reduce the losses considerably by reviewing the process parameters and increasing the profit exponentially. It constitutes a systematic approach to assure that food products have particular traits at any stage of production and distribution.

Abstract

Wild medicinal plants have been major source of therapeutic agents for alleviation or cure of human diseases since time immemorial. These are extensively utilized throughout the world in two distinct areas of health management i.e., modern medicine and or folk medicine. Some of the important medicinal plants grown and cultivated in India for medicine, phytochemicals, nutraceuticals, cosmetics and others are Abelmoschus moschatus, Aristolochia bracteata, Cassia alexandrina, Caralluma fimbriata, Gymnema sylvestre, Withania somnifera and other species. They have become important sectors of trade and commerce. However, in India, about 90% collection of medicinal plants is form wild source and since 70% of collections involve destructive harvesting, many plants have become endangered or vulnerable or threatened. The increasing demands of the pharmaceutical industry have created problem of supply and one of the major difficulties being experienced by the industry is that of obtaining sufficient quantities of medicinal plants for the manufacture of genuine medicine.

Grasses, bamboos, sedges and rushes are plants that are being used increasingly in xeri-scaping and in marsh gardens for getting the benefits of their unusual foliage textures and colours. Their hardiness, stature and canopy frame make them more suited for specimen planting in gardens and landscapes.

GRASSES

Grasses are the most successful of monocots belonging to the family Poaceae that are found the world over. Low growing perennial grasses are used to make attractive lawns in gardens and to provide a desirable turf cover for various situations. A number of species belonging to various genera differing in leaf colour, shape and growth pattern are used for this purpose. Mixtures of different varieties of grasses are also used for making turf having desirable blends of textures and hardiness. Tall bushy grasses having a mound-like or fountain–like habit and fine to velvety surfaces are grown for their textural and architectural features in landscaping. Many are grown as specimen plants for their display value at flowering. In selecting grasses for gardens, their potentially invasive nature is to be taken into account and seed dispersal controlled by timely cutting.

Grass species that thrive in the hot and humid tropics are called warm-season grasses and include Bermuda grass, Carpet grass and St. Augustine grass. Cool season grasses that are adapted to temperate regions and thrive at temperatures of 10 to 20^oC include Blue grass, Fescues and Zoysia.

Limitation of Weende Method

The partition of carbohydrate into fiber (CF) and nitrogen free extract (NFE) is presumed to represent a separation of less digestible starch and sugars. However, in 20 to 30 percent feeds listed by Morrison, the NFE is less digestible than the CF. This comes about for several reasons, the most important of which is the CF method (successive boiling with dilute sulphuric acid and sodium hydroxide) does not recover all the fiber and large portions of fibrous constituents  are extracted into the NFE. The most  important of these fractions are lignin and hemicellulose are dissolved by both acid and alkali. The basic error of the NFE concept is the assumption that if constituents are soluble they are digestible. Lignin, the rigid component of wood, not only is indigestible but lowers the digestibility of substances with which it is associated.

Another portion of the indigestible part of NFE arises from an artifact in the calculation of faecal NFE, where it is presumed that faecal nitrogen is protein (N x 6.25). Actually, 80-90 percent faecal nitrogen is NPN and is composed of bacterial residue in which the ratio of organic matter to nitrogen is about 1:4. Thus, part of the faecal NFE arises by an underestimation of the organic matter associated with faecal nitrogen.

13.1 Introduction

At a national level, the agricultural sector is one of the major potential users of energy in the Indian context. Further, it is often highly dependent on the supply of electricity and fuel in order to function properly. The term “agriculture” refers to all on-farm activities required for farming, raising animals, and associated activities associated with farmers, growers, and entrepreneurs. Fuels such as petroleum and electricity are primarily used for the operation of pump sets and other operations. In the future, this may result in problems with supply and price. Moreover, India has relatively small reserves of crude oil and will eventually be forced to import more crude oil to make up for the lack of reserves. In order to save energy and money on the farm, farmers must identify opportunities for energy conservation on the farm in order to maximize energy efficiency. 

Macaroni: Pasta made from semolina and shaped in the form of slender tubes (Plate 396).

Macaroni wheat: It is tetraploid wheat and is preferred for making macaroni, vermicelli etc.

Macaroon: A small cookie composed chiefly of egg whites, sugar, and ground almonds or coconut (Plate 397).

Mace: An aromatic spice consisting of the dried external fibrous covering of a nutmeg (Plate 398).

Mach number: It is a number representing the ratio of the speed of a body (flow velocity) to the speed of sound (sonic velocity) in a surrounding medium (as air).

Macroglobulin: A highly polymerized globulin of high molecular weight.

Macronutrient: A chemical element (as nitrogen, phosphorus, or potassium) of which relatively large quantities are essential to the growth and health of a plant or a substance (as protein or carbohydrate) essential in large amounts to the growth and health of an animal.

Extensive studies have been carried out to explore the possibility of using mycorrhizal model system in inducing suppressions of potential soil-borne pathogens. Its relevance becomes all the more important since most of the soil-borne diseases, by and large, are not easily controlled by conventional methods.

Diseases due to Fungal Pathogens

Most of the studies conducted on the interaction of VAM fungi and fungal pathogens suggest that mycorrhizae decrease the severity of disease, while a few studies suggest that there is either no effect or there is an increase in the severity of disease. It has been pointed out that in view of the fact that VAM fungi deter the severity of disease they may be used as biocontrol agents. Various mechanisms by which VAM could suppress the fungal pathogens have been suggested on the basis of experimental evidences.

8.1 Introduction

Electron Microscopes were developed due to the limitations of Light Microscopes which are limited by the physics of light to 500x or 1000x magnification and a resolution of 0.2 micrometers. In the early 1930’s this theoretical limit had been reached and there was a scientific desire to see the fine details of the interior structures of organic cells (nucleus, mitochondria etc.). This required 10,000x plus magnification which was just not possible using Light Microscopes. The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to see through the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931. The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in scanning the beam of electrons across the sample. Electron microscope has been a valuable tool in the development of scientific theory and it contributed greatly to biology, medicine and material sciences. This wide spread use of electron microscopes is based on the fact that they permit the observation and characterization of materials on a nanometer (nm) to micrometer (µm) scale. Electron Microscopes are scientific instruments that use a beam of highly energetic electrons to examine objects on a very fine scale. This examination can yield information about the topography (surface features of an object), morphology (shape and size of the particles making up the object), composition (the elements and compounds that the object is composed of and the relative amounts of them) and crystallographic information (how the atoms are arranged in the object). A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that can be detected and that contain information about the sample surface topography and composition. SEM can achieve resolution better than 1 nanometer. The combination of higher magnification, larger depth of focus, greater resolution, and ease of sample observation makes the SEM one of the most heavily used instruments in research areas today.

According to Pasteur statements which one of the following is true

a) Living organisms discriminate between stereo isomers

d) Both a and b

Theory

Research: The word research is composed of two words “Re” and “Search”.
“Re” - ‘Again or over again or a new’ 
“Search” - ‘To examine closely and carefully’ or ‘to test and try’. 
Research is a careful, systematic, patient study and investigation in some field of knowledge undertaken to establish principles / policies. 
Science: It is a systematized knowledge derived through observation, experimentation or any other systematic method or procedure in order to determine the nature of phenomenon or process being studied or the causes behind specific events.

Carbohydrates are the most abundant biomolecules on earth. They occur in nature as glucose, starch and cellulose etc. Each year, photosynthesis converts more than 100 billion metric tonnes of carbon dioxide and water into starch, cellulose and other plant products. Carbohydrates are polyhydroxy aldehydes or ketones and their derivatives. They provide 4k calories energy per gram. They promote utilization of lipids and reduce wastage of proteins. They are readily available in roots, tubers, cereal grains, sugarcane and sugar beet.

Carbohydrates have the general formula C_n( H₂O)n, indicting that they are the hydrates of carbon. Some carbohydrates also contain nitrogen, phosphorous or sulfur. They are characterized by the number of carbon atoms they contain. If n=3, they are trioses, n=4 tetroses, n=5 pentoses, n=6 hexoses and n=7 heptoses. The most common sugars in plants are the hexoses. Two or more simple carbohydrates condense together to form polymer sugars like sucrose, starch and cellulose etc. The basic condensing bond is glycosidic bond.

4.1 Introduction

A huge amount of waste in the form of liquid and solid is produced in the fruit and vegetable processing industry which causes pollution problem if not utilized or disposed off properly. Generally solid waste is dumped in local landfills, eaten and scattered by stray animals, which has now become a major cause of environmental pollution. The waste obtained from fruit processing industry is extremely diverse due to the use of wide variety of fruits and vegetables, the broad range of processes and the multiplicity of the product [79]. The solid waste from fruits and vegetables includes peel, stone, rag, seed, core etc is of economic value and can be used for manufacturing of various by-products [21]. The extent of the waste produced from processing industries of some of the important fruits and vegetables, is given in Table 1.

In India, utilization of fruits and vegetables for processing is hardly 1.8% of the total production. There were 5166 processing units till 1^st Jan, 2009 of fruits and vegetables products throughout the country. About 90% of these units are small scale units with annual production limit of 50-250 tonnes. These units have no organized methods of waste disposal. In certain places this waste is taken away by farmers for their disposal as cattle feed or field manure.

Introduction

Technical innovation is a process by which new or improved technologies are developed and brought to widespread use (Ambuj Sagar, 2013). Technical innovations are interlinked by research, development, demonstration and deployment which involves a range of organizations and personals with institutional arrangements underpinning the growth and advancement of different kinds of technologies. In the area of water productivity, technical innovations has helped expand water supplies through improved exploration and recovery techniques, increased water use efficiency, improved water availability and reduced environmental impact of water and its usage.

Introduction

Diffusion is the process by which an innovation is communicated through certain channels over time among the members of a social system (Rogers, 1962, 1983, 1995, 2003). It is a broader term, which encompasses unplanned as well as planned and directed spread of an innovation. Dissemination is planned and directed diffusion of an innovation. In case of Integrated pest management which is a complex sort of decision making process, many technology transfer approaches were/are tried for dissemination of IPM technologies to farmers. These include radio, television, print media, training and visit, field days, demonstrations, extension field visits and participatory learning approaches like participatory technology development (PTD) and farmers field school (FFS). While Training and Visit (T&V) system failed, Farmers Field School (FFS) approach of educating farmers followed by ‘Community IPM’ activities and ‘Farmers to Farmer’ approach registered success in IPM implementation in developing countries (Matteson, 2000).

Introduction

India ranks second in the production of vegetables after China. The existing area under vegetable cultivation in India is around 4.5 million ha. There is a need of around 5-6 million tons of food to feed 1.3 billion India’s population by 2020 AD. The major constraint in vegetable production, include the extensive crop losses due to increased pest infestations directly or due to viral diseases vectored by insects. The extent of crop losses in vegetables varies with the plant type, location, damage potential of the pest involved and cropping season. Vegetables are more prone to insect pests and diseases mainly due to their succulence as compared to other crops. The crop losses to the tune of 40 per cent have been observed in vegetable crops. The increased demand and limited productivity of local cultivars, led to introduction of high yielding varieties and hybrids. As a result, dramatic changes in pest scenario occurred like minor pests assuming major status (eg., Serpentine leaf miner, Liriomyza trifolii a serious problem in tomato hybrids). Chemical pesticides are the sole panacea to mange the pest by vegetable farmers even today. Indiscriminate use of pesticides has led to severe ecological consequences like destruction of natural enemy fauna, effect on non-target organisms, pesticide residues in vegetables and resistance of the pest to pesticides. The modern pest management is aimed at educating the farmers on various issues of pest management like identification of the pests, natural enemies, judicious use of pesticides with alternate methods of pest control like cultural, mechanical, biological and behavioral (pheromones) management.

Introduction
The method of selective breeding involves selecting particular breeding prospects to accumulate beneficial alleles and increase the prevalence of desired traits in a population. Characteristics, including growth, disease resistance, reproduction, development, and coloration, are frequently addressed in aquaculture (Maluwa, 2022). Selective breeding, whereby people are picked to have offspring with desired traits, is the foundation of genetic improvement initiatives in all organisms. This is a type of directed evolution in which the breeder determines fitness instead of the organism’s innate capacity for survival and procreation. Darwin’s theory of natural selection was affected by selective breeding, which existed before the mechanics of heredity were discovered. Darwin agreed that deliberate human selection used excellent outcomes (Hill, 2017). By choosing better parents, a species’ desirable features can be improved. Common carp (Cyprinus carpio) were first cultivated in ponds in China 4,000–5,000 years ago, marking the beginning of fish farming. Environmental effects, growing competition for water, and increased demand due to population development and declining wild fish sources are some of the issues aquaculture faces as it grows. Controlled mating and lineage monitoring were two early breeding techniques that resulted in severe inbreeding and decreased output. Mendel’s plant experiments established the groundwork for quantitative and contemporary genetics when they were made public in
1900 (Gjedrem and Baranski, 2010). Mendel’s experiments were confirmed in 1900, marking the beginning of selective breeding for plant production. Fifteen years later, Farm animals were treated using the same methods (Hagedoorn, 1950). Genetically modified stocks are used for most plant and farm animal production. Genetic advancement in aquaculture is still sluggish, though. Although the first aquaculture family-based breeding program began in 1975, by 2010, only 8.2% of aquaculture production was based on genetically modified stocks (Neira, 2010; Rye et al. 2010).

The world turned into a grossly inhabitable during the infamous COVID-19 pandemic, with community health issues everywhere. Each one felt unsafe if other earthly inhabitants were, be it humans or other living beings. Onset of SARS CoV-2 set a ‘new normal’ world order. The ever-evolving and mutating SARS CoV-2 variants extended the pandemic wave after wave thereby complicating the situation, pushing the global healthcare system to its limits and exposing its underbelly. The continually evolving variants were more aggressively transmissive and infective. As the world still reels under tremendous healthcare pressure, other infectious diseases are emerging as are identified by the World Health Organisation (WHO), creating international health emergency situations. The situation becomes alarming with the increasing zoonotic (spillover) and reverse zoonotic (spillback) factors being more proactive in the disease spread. There is a greater need to vaccinate not only humans but also animals, especially the domesticated ones and known reservoirs/carriers. Vaccines must be developed on priority and equitably distributed as the first step to counter a pandemic or potential pandemic. Vaccination is self-limiting due to increasing reported breakthrough infection cases. A strong link of the environmental health to the overall global health needs to be acknowledged, and due diligent measures taken. Hence, there is a strong need of the One Health approach as a 360° solution, and follow it up at global-scale both in letter and spirit. This chapter discusses spillover and spillback of diseases like SARS-CoV-2 and Mpox as case examples, the mitigation strategies and the need for workable One Health models, and challenges and measures to counter future outbreaks. It stresses on foolproof vaccination strategies across to catalyse individual and herd immunities for universal wellbeing.
