Introduction
Infection prevention and control refers to prevention and control of infections and their transmission in healthcare settings. Healthcare Associated Infections (HAI) are one of the most common adverse events in delivery of care and a major public health problem with an impact on morbidity, mortality and quality of life. Up to 7% of patients in developed and 10% in developing countries acquire at least one HAI. These infections also present a significant economic burden for the health system.1It is evident that HAIs result in prolonged hospital stays, long-term disability, increased resistance of microorganisms to antimicrobials, additional cost on health systems, high cost for patients and their family, and preventable deaths.

Introduction

Rice contains essential micronutrients such as iron (Fe), zinc (Zn), copper (Cu), calcium (Ca), manganese (Mn), magnesium (Mg), etc. which are generally lower when compared with other staple crops like wheat, maize, legumes, and tubers (Adeyeye et al. 2000). The most crucial micronutrients are iron and zinc, whose inadequacy is a leading cause of malnutrition. In this chapter we discuss estimation methodologies and diversity of Fe and Zn, its genetic basis, and improvement for micronutrient content through breeding techniques.

Procedure of Estimation of Fe and Zn Content in Rice Grain

Iron and zinc concentrations in rice samples were generally estimated by colorimetric method Atomic Absorption Spectrometry (AAS), X-ray Fluorescence (XRF), and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). X-Ray Fluorescence (XRF) Spectrometry is extremely helpful in the non-destructive estimation of relative Zn and Fe concentration in rice breeding lines and large germplasm collection (Paltridge et al. 2012). The majority of biofortification programs employ XRF as a metal analysis tool. For estimation of Fe and Zn, panicles of middle row plants of each replication were harvested, sun-dried for 4-5 days to reduce the moisture content to 11-12 %, and then seeds were dehusked. Each brown rice sample of about 5g was subjected to energy dispersive X-ray fluorescent spectrophotometer (ED-XRF) as per standard protocol (Stangoulis and Sison 2008, Rao et al. 2014) and expressed in ppm (µg g-1).

Tomato (Solanum lycopersicum L.) is one of the most commercially important vegetable crops globally, with a significant demand for high-yielding hybrids and improved open-pollinated varieties. Efficient seed production methodologies play a crucial role in ensuring the availability of genetically pure and high-quality seeds for commercial cultivation. Traditional hand emasculation and pollination remain widely used despite being labor intensive, given their economic feasibility due to high seed yield per fruit. Hybrid seed production is further refined through mechanized pollen collection and controlled pollination techniques, enhancing efficiency. Seed quality management, including rigorous isolation protocols, field inspections, and breeder and foundation seed production standards, ensures genetic purity and viability. Advances in molecular breeding and the application of marker-assisted selection (MAS) have enhanced the efficiency of parental line development and hybrid seed production. This chapter provides an in-depth review of tomato seed production methodologies, covering botanical characteristics, genetic resources, and breeding objectives aimed at improving disease resistance, abiotic stress tolerance, and fruit quality traits. It further discusses varietal advancements in the public and private sectors, highlighting elite hybrids and open-pollinated cultivars tailored for different agro-climatic conditions. Additionally, the package of practices for seed production in tomato underscores the importance of isolation, field inspections, seed extraction methods, processing techniques, and quality assurance standards to maintain genetic purity and seed viability.

Use of morphological markers has continued till today for characterization of several crops including horticultural crops with the Mendel’s principles of inheritance by following visible traits in the progenies of sexual crosses. Genetic markers play an essential role  in the study of variability and diversity, in the construction of linkage maps, and in the diagnosis of individuals or lines carrying certain linked genes. Within this context, the limitations of morphological markers became quickly apparent. They tend to be restricted to relatively a few traits, display a low degree of polymorphism, are often environmentally variable in their manifestation, and can depend on the expression of several unlinked genes. Furthermore, some may affect plant viability or seed set, distorting gene frequencies in the progeny. Morphological markers were largely supplemented by biochemical markers, particularly isoenzymes that could be easily scored by electrophoresis (Ganapathy and Scandalios 1973; Tanksley 1983). The limitations of isoenzmyes as markers, in particular both the limited number of polymorphic enzymes that can be conveniently stained and the environmental effects on expression pattern, were apparent already twenty years ago (Tanksley 1983).

5.1 Introduction

The densification of biomass involves transforming loose and low-density organic materials, such as wood residues, agricultural waste, and plant-based materials, into compact and energy-dense forms. This process is necessary because natural biomass can be challenging to handle, transport, and store. Densification uses mechanical, thermal, or chemical processes to increase the material’s density and energy characteristics. The resulting products, such as pellets, briquettes, or cubes, offer several advantages, including higher energy content per unit volume, efficient storage and transportation, reduced moisture content, and improved combustion efficiency. These products are utilized in various industries, including energy production, residential heating, waste management, and industrial applications. Biomass densification promotes sustainable practices by effectively utilizing biomass resources, reducing waste, and promoting the use of renewable energy sources while mitigating environmental impacts.

INTRODUCTION TO DRONES USED FOR EARLY PEST AND DISEASE DETECTION
The utilization of drones for the early detection of pests and diseases in agriculture represents a novel and effective strategy that enables farmers to proactively oversee crop health. Drones outfitted with sophisticated sensors can consistently surveil fields, delivering real-time data and facilitating the prompt detection of possible dangers.
Agricultural drones are employed to identify pests and illnesses at an early stage by capturing aerial imagery of crops. This enables farmers to respond swiftly to safeguard their crops, perhaps resulting in increased yields and reduced environmental impact.
The utilization of drones in agricultural pest management presents numerous benefits compared to conventional techniques. Drones outfitted with infrared cameras can furnish farmers with real-time information on crop health, facilitating the early identification of possible problems such as pests, illnesses, or nutritional deficits.
Pathology can adversely affect plant vitality prior to the manifestation of any obvious indicators such as foliar discoloration. Although these pressures are imperceptible to the unaided eye, cameras equipped with specialized filters may identify these nuanced variations.
Researchers at the Department of Life Sciences and Computing are collaborating with the agricultural services firm Agrii to develop cameras placed on drones. These cameras can autonomously identify early signs of disease and notify farmers when to apply treatments, prior to crop harm.
Applying fungicides promptly in the appropriate locations would enable farmers to utilize them effectively and optimize their application. They are

Quality is an increasingly important factor in the production and marketing of biological products. Consumers are becoming more discerning as their affluence increases, and would be suppliers of products must meet these demands if they are to maintain or increase market share. The term ‘quality’ is one of the most defined terms in use in food industry today. Quality may be defined as ‘The totality of features and characteristics of a product that bear on its ability to satisfy a given need’. The first part, ‘The totality of features and characteristics of a product…..’ concerns objective factors related to the product.  The second part, ‘…… to satisfy a given need’, concerns subjective factors related to user or consumer of goods.

Ethylene is a primary plant hormone involved in the senescence of plant tissues including flowers and leaves. In carnation flowers, inhibition of the synthesis or action of ethylene delays the onset of senescence symptoms and lengthens the vase life of flowers. Leaves of cut chrysanthemum of some cultivars frequently become yellow, sometimes prior to the onset of flower senescence, in response to exogenous ethylene. Generation of transgenic plants with suppressed production or action of ethylene is an excellent way to lengthen the longevity of these ornamental plants. This paper reviews our studies on generation and characterization of carnations with reduced ethylene production and chrysanthemum with reduced sensitivity to ethylene.

8.0. Introduction

Food additives are the substances not normally consumed as a food by itself and contain or not contain nutritive value but are added to food to improve freshness, sensory and keeping quality of food. So, a food additive is defined as a substance or a mixture of substances other than the food stuff incorporated in food either directly or indirectly as a result of any phase of production, processing, storage or packaging to improve or maintain the nutritional value, enhance quality, consumer acceptability and facilitate the preparation of materials e.g., acid, alkali, bleaching agents, emulsifying & sterilizing agents, flavours, colours, nutrient supplements, clarifying agents, humectants, chemical preservatives etc. Every food available in the market or at home contains food additives. So, now the question arises that whether additives are safe from consumption/toxicological point of view or not? What are the facts or fictions, if additives are to be used in the food preparation? These are the most important questions to be answered and discussed before their use in food industry.

Introduction and Background

Agriculture at present has the trend of using an industrialized production model, where crops and animals are produced in systems that are increasingly specialized, simplified and concentrated, to address growing food, feed and fibre demands. Within this model, external inputs (e.g. irrigation, synthetic fertilizers chemical pest control, feeds, and growth hormones) have been utilized to achieve production goals, often at the expense of environmental quality and key ecosystem services. Continuation of this model of agricultural production has resulted in loss of ecosystem services, increased ecosystem simplification and species extinction. Responses to future challenges in agriculture should include the development of novel systems that are highly productive, minimize damage to the environment and effectively utilize renewable resources. Achieving these multiple goals will be a momentous task, as it will require development and implementation of more complex, diverse and management-intensive production systems than currently employed. Furthermore, future agricultural production systems will need to be adaptable to respond to unforeseen environmental challenges. Integrated agricultural systems have been purported to possess attributes to address these challenges. Agro-chemicals, fuel-based mechanization and irrigation operations are the heart of industrial agriculture which is derived entirely from dwindling and ever more expensive fossil fuels. Intensification of agriculture by the use of high yielding crop varieties, fertilization, irrigations and pesticides are impact heavily on natural resources with serious health and environmental implications. Practice of monoculture in some parts of the country and the world has an adverse environmental impact due to lack of ecological regulation mechanisms and heavily dependent on external inputs.

Introduction

The value of data privacy in the linked world of today cannot be emphasised. As digital technologies proliferate and personal data is collected, stored, and analysed on a large scale, people and organisations are more susceptible to data exploitation and privacy violations. In the modern era, privacy of data are vital because of following reasons:

1. Safety Regarding Personal Information: Fundamental People’s freedom to manage their personal data protected by data privacy. In a time when everyone has a digital footprint, maintaining one’s liberty and dignity requires protecting private information such as financial records, health records, and internet activity

2. Trust Management is Critical for Organisations and Companies: Maintaining data privacy improves reputation and brand loyalty by building trust with stakeholders, clients, and consumers. On the other hand, privacy violations and data breaches can seriously harm an organization’s reputation by undermining people’s confidence in its ability to protect sensitive data.

3. Compliance with Laws and Regulations: Strict data privacy laws have been passed by governments all over the world to uphold people’s rights and make businesses responsible for handling personal information. Adherence to regulatory mandates similar to the General Data Protection Regulation (GDPR) in the EU and the California Consumer Privacy Act (CCPA) in the US not only necessary from a legal standpoint but also morally required for moral business practices.

Landscape models focus on both the integrated master landscape planning of a home gardening and specific garden design. The people should be educated to realize the importance of gardening, by providing good parks and gardens in cities for a large population to relax and enjoy the beauty of nature. The plants used in the landscape designing of gardens are directly or indirectly involved in increasing the aesthetic value of the city, changing microclimate, social behaviour of the people, checking pollution etc. The importance of landscape gardening in human welfare cannot be overlooked. Even in an under-developed country as India, people do not live by bread alone. They also need some finer things of life. The models described in this chapter are very basic features of any garden.

Garden Walls

A garden lover will never like to block the view of his garden by putting a wall along periphery of the garden. A garden as it is enjoyed from inside should also be visible from outside but sometimes, it is necessary from safety and beauty point of view to obscure the ugly sight of an open drain. A compromise is to have a low brick wall of say 60-90 cm height and to put over it some grills, so that the view is not totally obstructed from outside. Alternatively, walls from 1.80 to 5.0 m may also be erected based upon the size of the garden.

Big Data refers to extremely large, very fast, highly diverse, and complex data that cannot be managed with conventional data management systems, tools or processes. In the perfect world, Big Data may include all kind of data, which can deliver the right information, to right person, in the right quantity, at the right time, to help in making the right decisions.

Gasification is a process that turns materials containing carbon, like wood, crops, coal, or waste, into a type of fuel called producer gas or syngas. This is done by heating the carbon-rich material with a controlled amount of oxygen at high temperatures. Gasification is a type of partial oxidation, which means using less oxygen than needed to burn the same amount of fuel. Knowing the necessary amount of air for the conversion process is important to run a gasifier correctly. This requires understanding the stoichiometry based on the composition of the biomass. A chemical formula for the biomass can be calculated by analyzing the elements present, which serves as the basis for estimating the air-fuel ratios through stoichiometric calculations. Gasification only uses 25 to 40% of the theoretical oxidant, producing heat for fuel conversion. In gasification, the main combustible products are carbon monoxide and hydrogen.

Abstract
 
Food products can have moisture content as high as 90% which needs to be lowered to acceptable limits to prevent microbial growth and deteriorative reactions. Drying is one of the most common and cost effective techniques for removal of excess moisture from the food by application of heat. In addition to its role of extending the product shelf life and providing stability, drying also helps to produce variety of products from agricultural, horticultural and industrial products. But to obtain the desired quality product, adequate drying is essential which depends on type of dryer and drying technique employed which further requires proper understanding of drying process. Despite being important unit operation in food processing industry, appropriate scientific knowledge of the drying process is still limited. So, the fundamental principles and associated terminologies with drying has been discussed in detail in this chapter to have thorough understanding of the drying process. In addition, different models and calculation procedures for drying of different types of commodities has also been reviewed.

Introduction

The food processing industry is a sunrise sector and contributes around 14% of Gross Domestic Product, 13% of India’s exports and 6% of total industrial investment. The Indian food retail market is expected to reach Rs 61 lakh crore by 2020 and the food processing industry accounts for 32% of the country’s total food market. This is considered as one of the largest industries in India and is ranked fifth in terms of production, consumption, export and expected growth.

The drift towards urbanisation and busier way of life, pave path to tremendous bounce in the food market. Nowadays consumer’s approach to being fit is not about going to gym, but also consulting dietitians and adopting an adjusted eating routine. Consumer’s behaviour concerning food consumption has undergone significant changes as a result of the increased awareness about different value added food products, brands, and cuisines, and also their greater willingness to experiment and ability to pay. It leads to the concept of food security in to nutritional security. Companies are offering a wider range of products to the consumers as a result of their investments into product innovation, research and development. At present, various value added products with versatile colour, shape, ingredients etc are available in worldwide market. Among this, some food items like processed fruits and vegetables and dairy products have witnessed a momentous growth in export also. Recent surveys indicated that for companies manufacturing processed foods and beverages, rise in the obesity rate is a great challenge. Hence, efforts were made to develop commercially viable, new process protocols to design healthy products from underutilised food commodities.

Introduction

Cereals and cereal products comprise a long history of consumption by humans. Cereals are the important source of nutrients and non nutritive health beneficial components and for that reason cereal based food products are consumed as staple food in human diet in developed as well as developing countries. The cereal grains mainly cultivated and consumed as food include rice, maize, wheat, sorghum rye, barley, oats, and millet. Products obtained from cereal grains are flours, grits, semolina, breakfast cereals, extruded product like pasta, puffs and flakes, and bakery products such as bread, biscuits, cakes and tortillas. Moreover, cereals or their components are used as ingredients in the preparation of various food products such as beverages infant foods coatings and processed meats. Initially cereals are consumed as whole or with minimal processing like boiling, grinding and roasting. However, processing like salting, drying, steeping and fermentation of cereals for preparation of cereals based beverages and foods has been practiced since the initiation of cereals consumption as food by human. Increasing consumer awareness and commercialization of cereal products have created interest of food manufacturers in utilization of novel and more efficient technologies with optimized conditions, development of convenient and more health beneficial foods with satisfactory sensory properties and wide variety of foods to ease the choice of consumers. Market full of diverse range of snack foods, breakfast cereals, ready to eat and ready to cook foods, and novel functional foods with variation in appearance, texture and flavor is an indication of evolution of food industry from basic to complicated form focused on efficient and automated operations. In ancient times, fermentation of food was done with the aim of enhancement of shelf life and palatability without clearly knowing the role of microorganisms. Modern fermentation technology uses various operations and specific strains of microorganisms for conversion of bulky and perishable materials into novel foods with more pleasing flavour, enhanced functional properties and extended shelf life. In addition to basic bread, new varieties of bread developed with improved functionality like sourdough bread, gluten free breads and high fibre breads is an example of innovation in cereal fermented foods indicating modification in ingredients, microbial culture and processing technologies as compare to traditional fermentation process. The word “extrudate” is derived from the Latin word “ex” meaning ‘out’ and “trudere” meaning ‘to thrust’. Extrusion technology is turning out to be very popular in food industry due to its versatility, usefulness and cost efficiency. It is well-organized state-of-art technology and plays important role in various food industrial processes such as cooking, mixing, conveying, shearing and shaping of end products. Extrusion cooking is high temperature short time (HTST) with high pressure process, is especially used for preparation of cereal based snacks, fat replacers, breakfast cereals, infant formula, gluten free foods, starch and protein rich cereals food products. A wider range of ready to eat food products with different texture, size and shape is produced by fast and easy extrusion cooking. In epidemiological studies it is stated that whole grain consumption is more health beneficial than refined grains and the reason behind it is that dietary fibre and phytochemicals located in germ and seed coat are generally removed during milling or polishing. Various technologies are developed by food scientists and technologists to preserves the bioactive compounds during processing and or to supplement processed food products with the bioactive compounds during food preparation to maintain the bioactivity and functionality of final products. Utilisation of whole grain flours, composite flours, supplementation of cereal foods with ingredients from fruits, vegetables, plant extracts and legumes, bio-fortification of crops, implementation of genetic engineering to produce crops rich in bioactive compounds are some technologies which are being used in modern food industry to develop value added cereal food products.

Protection of Plant Varieties and Farmers’ Rights Act-2001 (PPVFRA-2001) was enacted by government of India in 2001 to create a sui generis system of providing a legal framework as an IPR mechanism to protect the varieties of crop plants in India along with grant of breeders’ and farmers’ rights in the interest of all the stakeholders and also to comply with WTO guidelines to which India is a legal signatory.

Bitter gourd (Momordica charantia L.) is one of the important commercial cucurbitaceous cash crops grown mainly by small holding farmers in Asia where it is cultivated on more than 340,000 ha annually (McCreight et al., 2013). Eastern Asia, possibly Eastern India, or Southern China is most likely the center of origin for bitter gourd (Walters and Decker-Walters 1988; Miniraj et al., 1993). It is also known as bitter melon, bitter cucumber, balsam pear, bitter apple, or bitter squash (Morton, 1967). Fruits are known for abundant source of vitamins and minerals. Delicious preparations are made from fruits after stuffing and frying. It is also consumed in the form of Juice, Tea and Pills. Bitter gourd fruit abounds in phytonutrients (Dhillon et al., 2017) and often used to manage type 2 diabetes as a folk medicine. Clinical studies confirmed that elevated fasting glucose levels in pre-diabetics can be reduced by supplementing the diet with bitter gourd fruits. (Amirthaveni et al., 2018; Krawinkel et al., 2018). Medicinal properties present in the bitter gourd fruits are used in the curing of diabetes, asthma, blood diseases and rheumatism.

The current seed market of bitter gourd in Asia values ≈ 16 million Euros. The bitter gourd seed market in India alone is 400 metric tonnes having value of 350-400 crores. 70 % area is under hybrids and 30 % is covered by open pollinated varieties.
