9.1. Introduction

In a fast-paced world, demand for pre-cooked, fresh-like, and convenient products without preservatives is increasing. This demand has triggered the need for better alternative packaging materials for food products like MAP (Modified Atmosphere Packaging), CAP (Controlled Atmosphere Packaging), edible packaging, biodegradable packaging, etc. Packaging plays a crucial role in transport, distribution, storage, retailing, and end-use, a means of ensuring safe delivery to the ultimate consumer in sound conditions at optimum cost. It performs the functions depicted in Fig.1 for both fresh as well as processed products (Opara et al., 2007; Opara, 2009).

1. Introduction

The demand for non-dairy based beverages in form of non-dairy milk is on rise due to several reasons. Firstly, the prevalence of lactose intolerance and milk allergy amongst a major percentage of population who cannot consume dairy milk and look for alternate source of proteins. The need for functional drinks is also a major factor which contributes to the increase in demand of milk-alternatives. It has also been reported that milk processors around the world face an uphill battle, including the dominance of private labels; consumer concerns over the presence of growth hormones in non-organic milk; fluctuations in commodity prices; supply shortages for organic milk; and growing consumer concern about the safety of animal products in general. With that long list of challenges, the market has had few growth opportunities even though consumers continue to prize milk for its nutritional benefits.

2. Need for Non-dairy Beverages

2.1 Prevalence of lactose intolerance

Lactose intolerance is estimated to affect 33 % of the global population, but the prevalence of the condition varies from country to country. It is also estimated that an average of 75 % of human adults have decreased intestinal lactase activity after weaning (NDDI, 2012).

Millets have potential as both food and fodders crops. Foods made from millet are abundant in micronutrients and necessary amino acids for regulatory functions. Since, millets were traditionally grown under adverse conditions, a great amount of polymorphism was preserved, making millet crops naturally resistant to abiotic and biotic stresses. Using data-driven technology to increase genetic gain in breeding operations can improve traditional breeding. Artificial intelligence can be used to create varieties that are adapted to certain soil and climatic conditions. In order to achieve breeding goals, machine learning (ML) is crucial in data mining and analysis, providing information for decision-making. We have been able to generate information on interesting genes using data mining and allele identification methods. For the exploitation of the natural variation and the identification of target genes, advances in high-throughput sequencing for the detection of genetic variations as well as the role of phenomics in genomics-assisted breeding can be employed. QTLs and marker-trait correlations can be identified via genome-wide association analyses. Multiple loci and genes that control agronomic traits have can be studied by comparative and functional genomics. Model selection is crucial for ML algorithms in smart breeding, which depends on knowledge in genotype, phenotype, and G×E interaction to be handled through computer science.

The quality of ice cream depends on the balanced interaction of its major and minor constituents. This chapter examines ice cream mix as a multiphase system and explains the chemistry and functionality of its principal components. Milk fat, milk solids-not-fat, proteins, lactose, sugars, stabilizers, emulsifiers, water, and other constituents are considered in relation to body, texture, flavour, viscosity, freezing behaviour, and stability. The chapter also discusses minor milk constituents and the ways in which individual components interact rather than functioning independently. Understanding these relationships helps manufacturers identify formulation-related defects and optimize composition for desired sensory, processing, nutritional, and storage characteristics.

1. The Aflatoxin Molecule

Aflatoxins are chemically difuro-coumarin derivatives. Presently, 18 different types of aflatoxins have been identified with aflatoxin B₁, B₂, G₁, G₂, M₁ and M₂ being the most common. Of these Aflatoxin B₁ (AFB₁) and G₁ occur most frequently, with AFB₁ being the most potent. Physicochemical and biochemical characteristics of the AFB₁ molecule reveal two important sites for toxicological activity (Heathcote and Hibbert, 1978). The first site is the double bond in position 8,9 of the furofuran ring (Figure 1). The interactions of aflatoxin, DNA and proteins, which occur at this site alter the normal biochemical functions of these macromolecules and leads to deleterious effects at the cellular level.Monteiro et al. (1966) studied the in vitro interaction of groundnut proteins namely arachin and conarachins with AFB₁ molecule. The second reactive group is the lactone ring in the coumarin moiety (Lee et al., 1981). The lactone ring is easily hydrolyzed and is therefore vulnerable to degradation.

Quality assurance is fundamental to producing safe, consistent, legally compliant, and commercially successful ice cream. This chapter presents a comprehensive QA framework covering supplier approval, incoming-material inspection, process monitoring, laboratory testing, microbiological control, sanitation, finished-product release, traceability, market quality, and corrective and preventive action. It explains the relationship between quality assurance, quality control, food safety, documentation, and management systems such as HACCP and ISO-based frameworks. The chapter also examines QA department structures, monthly reviews, audits, digitalization, quality culture, and performance indicators. By integrating prevention with measurement and accountability, the chapter demonstrates how effective QA can protect consumers, reduce losses, improve consistency, and strengthen profitability.

Research and development plays a central role in innovation, product improvement, cost optimization, and competitiveness in the ice cream industry. This chapter explains the distinction between research, development, and new product development and examines the responsibilities of an R&D department. It covers formulation development, pilot and plant trials, ingredient evaluation, shelf-life studies, regulatory considerations, supplier collaboration, product costing, and commercialization. The chapter also highlights the importance of cooperation between R&D, QA, production, procurement, marketing, and finance. Key performance indicators and common mistakes are discussed to strengthen the effectiveness of R&D programmes. The chapter ultimately connects scientific innovation with manufacturing feasibility, consumer expectations, regulatory compliance, and commercial success

Cleaning and sanitation are essential for maintaining microbiological safety in ice cream manufacturing, particularly because contamination can occur after pasteurization and freezing does not eliminate all microorganisms. This chapter explains contamination routes, hygienic zoning, cleaning systems, sanitization practices, HACCP principles, and microbiological expectations within an ice cream plant. It examines CIP and COP systems, detergent components, cleaning factors, high-risk equipment and surfaces, and post-pasteurization contamination control. Particular emphasis is placed on preventing biofilms and controlling contamination at filling equipment, tanks, pipelines, feeders, drains, packaging areas, and personnel interfaces. The chapter provides practical sanitation guidance to support food safety, product stability, regulatory compliance, and consumer protection

1. Introduction

Membranes separation processes have gained widespread applications in food industry. High selectivity of membrane has been exploited for separating a particular component from complex liquid food mixture and for controlled release of active ingredients like preservatives or flavor compounds. Today, a number of chemical processes utilizing the unique properties of membrane have been developed for commercial application in food industry with specific advantage of low energy requirement. Membrane separation/molecular sieving is one among those food engineering principals which has found broad range of applications including concentration of heat labile compounds, recovery of solvent, downstream processing, flavor volatile recovery, deacidification, desalination, waste water treatment etc

Joana et al.(2016) have written a critical review on biofilms and have discussed newer methods to study biofilms. These have given a deep knowledge on the physiology, structure and composition of biofilms. More polar amino acids were present in ABPs but QSPs were made up of higher number of neutral amino acids.This helps in recognition. Web application WebLogo help in generating sequence logos (Crooks et al., 2004). The uncharged polar amino acid is present at the first, third and fifth positions.The basis of SVM model is on the amino acid composition of the peptides. The Weka model is based on selected eight inputs which is trained on the NT5 dataset and is accurate, sensitive and specific.Peptide drugs are FDA approved and a total of 242 sequences of biotech peptides/proteins are available at the Drug Bank database. To identify potential anti-biofilm activity for characterization the peptide sequences are submitted on the module of dPABBs. The prediction outcomes are displayed under the ‘Putative ABPs’ section(http://ab-openlab.

Confectionery is an vital food item of great acceptance among wide range of population. It has been relished as a major food delicacy from ancient times. The term confectionery is describes a spectrum of sweet goods and takes on different meaning depending on the country in which it is used, for example in the United Kingdom the term applies to any sweet product including cakes. In the United States confectionery is candy and includes sugar confectionery and chocolate confectionery.

Fruit beverages

Fruit beverages are highly refreshing, thirst quenching, appetizing, easily digestible and nutritionally far superior to synthetic drinks. The fruit beverages includes natural and sweetened juices, squash, syrup, cordial, nectar, Ready to Serve (RTS) beverages, fruit juice concentrate and citrus juice barley water. Fruits most commonly used to prepare beverages are oranges, lime, pineapple, grapes, cashew fruit, mango, jack fruit, apple etc. To prepare fruit beverages select fresh, fully ripe, tart, juicy and seasonal fruits.

11.0. Introduction

Agricultural marketing is one of the important branches of agricultural economics. Farmers have one commodity or the other in surplus and need to be disposed off or sold to earn some money to satisfy other needs, which otherwise cannot be satisfied on the farm or in the village. Thus, agricultural marketing has two-fold objective i.e. Sale of surplus commodities and buy other commodities to satisfy family needs. In modern commercial agriculture, the surpluses with farmers are steadily rising, so also their family needs are changing with the change in lifestyle. Therefore, agricultural marketing has assumed important place. Traditionally, market is place or building where buying or selling of goods takes place. But, in modern times with fast and long distance communication facilities like telephone, market is no more restricted to a particular place only, but it has become wider and has assumed regional, national or even international status. Buying and selling is finalized on telephones only from distant places. Thus, the concept of market has radically changed.

So, marketing of food/ processed food is an important and vital constituent of modern business management. Knowledge about market is critical for the success of the product in such a highly competitive global market place. Now a day, in such modern time, marketing is itself a highly specialized and distinctive discipline. Based on marketing rules and laws, marketing is sometimes regarded as marketing science. Modern marketing strategies, tools and techniques have attained such complexity that marketing is linked with those of the modern warfare. The results of the marketing wars are witness by Cola wars and other brand bars being fiercely fought in the global market. So, the markets have become virtual battlefield for the brand wars. Markets and technologies are the two powerful forces driving the food processing industry. Further packaging has become a powerful tool in the promotion and marketing of the processed food products.

Abstract

In recent years microwave processing have attained increasing recognition in food industries particularly in drying and dehydration. During microwave processing, electromagnetic energy is supplied directly to the food material for volumetric heating. This provides rapid temperature rise throughout the material with reduced thermal gradients. This unique heating mechanism reduces processing time and saves energy. In-spite of advantages of microwave heating it leads to overheating in food material and formation of cold and hot spots if applied improperly during drying. To overcome these challenges different microwave assisted hybrid drying technologies have been developed by many researchers. These techniques are microwave assisted hot air drying, microwave assisted osmotic dehydration, microwave assisted vacuum drying, microwave- infrared assisted hot air drying, microwave assisted rotary drying. This chapter comprises the fundamentals of microwave and provides comprehensive update of microwave assisted hybrid drying processes for food and agricultural materials.

Horticulture is increasingly recognized as a sunrise sector, owing to its potential to raise farm income, provide livelihood security and earn foreign exchange through export. The diverse agro-climatic conditions and rich diversity in crops and genetic resources enable India to produce a wide range of horticultural crops round the year. To cite an example, India produces tropical fruit like mango and sub-tropical fruit like an apple at the same season in a year (Jha et al., 2019). The horticulture sector encompasses a wide range of crops like fruits, vegetables, flowers, spices, plantation crops like coconut, beverages like tea and coffee, and some medicinal and aromatic plants. Statistics provided by National Horticulture Development Board showed that India is the second largest producer of the commodities, after China, accounting for 13 per cent of the global production of fruits and 21 per cent of vegetables. (DAC&FW, 2017).

Economic reforms and policies further increased the speed of diversification in favor of horticulture crops (Jha et al., 2019). This is on account of the increased domestic demand from high-value food commodities as well as for export markets. The diversification process that is seen within the agricultural sector also got transmitted to the horticultural sector. In line with the emerging demands, India has taken several technical and policy initiatives for promoting horticulture. The most important among is the newer technology packages spanning from production to postharvest (Jha et al., 2019).

1. Introduction

Fruits and vegetables in fresh form in general contain very high water content, with the fast rate of metabolic activity, including respiration rate, which may vary with the fruit type. Accordingly, the storage life at room temperature is considerably less, to expect acceptable quality. A range of transformational changes occur in various features of the fruits and vegetables, such as color, flavor, texture, structure, sweetness, sourness, pungency, astringency and so on. Phenolic browning of mushrooms, intensive softening of papaya, coloration and softening of ripe banana, softening of pear and jackfruit , flavor transformations of mango, banana and jackfruit after ripening, their color and texture transformations, are classic examples of post-harvest changes in fresh commodities, over a course of storage period at room temperature. These physical and sensorial perceptions of fresh commodities over a length of storage period are based on the range and multitude of operations of physical, chemical and bio-chemical reactions occurring in various constituents of the fresh fruit or vegetable such as moisture, pigments, vitamins, pectin, cellulose, hemicelluloses, phenolics, lignin, sugars, flavor compounds, amino acids, fatty acids and so on. In order to increase the storage stability, the fresh fruits and vegetables are processed and converted into various products such as juice, RTS beverages, jam, jelly, marmalade, fruit spread, dehydrated, spray dried powder, frozen stored, fruit cereal flakes, canned, candied, fruit bar and so on. Based on the nature of processing, the original form, shape, size, texture and structure are transformed, however with due maintenance in storage acceptability. A number of external factors are applied to achieve this product range such as heat, air velocity, pressure, radiation, chilling, freezing, vacuum impregnation etc. The ultimate quality of the final product is essentially an interaction between and amongst the various chemical constituents so characteristic of each fruit or vegetable under study, and a sum total of positive and negative reactions related to sensorial acceptability of the product. This quality is again a function of the storage period and the conditions of storage. Consumers in modern days are more health conscious to choose between consumption of fresh or processed fruits and vegetables. For trade over distance and time and particularly for geographic regions not producing a particular fruit or vegetable, it is of utmost importance to process the fresh produce. Enzymatic transformations in color, texture and flavor deserve utmost attention to ensure acceptable quality of the processed product, in particular over the course of storage period or until consumed after transportation and marketing. Microbiological quality of the product in final form is a most vital factor of consumers' health and this is dependent on water activity, sugars and protein / amino acid contents. In this regard, additives and preservatives come into picture. Strict regulations are imposed on their use, type and concentration over a storage period, for healthy consumption. Accordingly, this chapter would deal with several examples of processing conditions influencing the quality of the product, that emanates. Processing involving chemical, bio-chemical, engineering, bio-technological and microbiological methods to achieve a product are vivid, varied and different to different species / variety of fruits or vegetables to target different products.

Key Facts
    
·    The United Nations Framework Convention on Climate Change (UNFCCC) defines ‘climate change’ as a ‘Change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over the comparable time periods’.
    
·    The main green house gases (GHGs) that have caused the global climate change or global warming are carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O).
    
·    CO₂ is the principal anthropogenic GHG that affects the earth’s radiative balance. It is the reference gas against which other GHGs are measured and therefore has a Global Warming Potential (GWP) of 1. CH₄ and N₂O have a GWP of 21 and 310 respectively.
    
·    CO₂ is responsible for most of the enhanced green house effect of more than 50%, CH₄ for about 10-15% and N₂O for about 8%.
    
·    The global atmospheric concentrations of CO₂, CH₄ and N₂O have increased since 1750. While CO₂ increased from a pre-industrial value of 280 ppm to 379 ppm in 2005, CH₄ increased from 715 ppb to 1774 ppb and N₂O increased from 270 ppb to 319 ppb during the same period.
