The jackfruit, Artocarpus heterophyllus Lam. of the family Moraceae, is also called jak-fruit, jak, jaca and, in Malaysia and the Philippines, nangka; in Thailand, khanun; in Cambodia, khnor; in Laos, mak mi or may mi; in Vietnam, mit. It produces the largest known edible fruit. In South-India, it is a common shade tree for many plantation crops. A jackfruit contains 28.7% pulp, 11.5% seed and 59.8% rind, sheath and core.

The place of origin of Jackfruit is not knows exactly, but it is believed to be indigenous to the rainforests of the Western Ghats of India. It is found at low elevations throughout India, Burma, Ceylon, southern China, Malaysia, and the East Indies. It is common in the Philippines, both cultivated and naturalized. It is grown to a limited extent in Queensland and Mauritius. In India it grows in a wild and semi-wild state in Assam, West Bengal, Tripura, Bihar, Uttar Pradesh and states along western Ghats range, particularly Kerala, Karnataka and Maharastra.

Cultivars: Rasdar, Khajwa, Rose-scented or Gulabi, Champa, Hazari, Rudrakshi.

Uses

Both mature and immature fruits as well as seeds are used for various purposes. Ripe fruit is used for dessert purpose and processing into various products, while unripe bulbs are used for making chips. The immature fruit and seeds are used as vegetable. The bark is used for tanning purpose. Heart-wood yield a yellow dye. A yellow dye can also be extracted from the wood particles and used to dye cotton. The latex which flows from all parts of the plant when injured is also used as adhesive. The resins within the latex may also have some value in varnishes. The timber is a medium hardwood with desirable characteristics for making furniture, oars, implements and musical instruments and the wood is also used in construction. It is termite proof and fairly resistant to fungal and bacterial decay. The roots of older trees are good materials for carving and picture framing Leaves are utilized as a green fodder. Several processed products, such as squash, nectar, fruit bar, toffies, jams, canned and dehydrated pulp, beverages, etc. are prepared from the pulp. The seeds can be eaten boiled, roasted or dried and salted as table nuts, or they can be ground to make flour and blended with wheat flour for baking (International Centre for Underutilized crops, 2003).

Jam is prepared by boiling the fruit pulp with required quantity of sugar to thick consistency, firm enough to hold fruit tissues in position. It should contain not less than 68.5 per cent soluble solids. Jam may be made from a single fruit (apple, strawberry, banana, pineapple etc.) or from combination of two or more fruits. Jam contains 0.5-0.6% acid and invert sugar should not be more than 40%.

Jam : It is a product prepared by boiling to a suitable consistency, fruit pulp with sufficient quantity of sugar, acid and pectin so as to set and become firm enough to hold the tissues in position. About 45 parts of pulp are used with every 55 parts of sugar. The finished product should not contain less than 68 per cent total soluble solids.

Jelly : Jelly is prepared by boiling the fruit pectin extract with sugar in the presence of appropriate amounts of acid so as to set into a clear gel. A perfect jelly is transparent, devoid of haziness or any suspended material well set, but not too stiff and should have original flavour of the fruit. When cut it should retain its shape and show a smooth cut surface.

Marmalade : It is a fruit jelly like product in which slices of fruit or peel are suspended in the set gel. Mostly they are prepared from citrus fruits like oranges, lemons etc.

Jamun, Syzygium cumini Skeels, belongs to the family Myrtaceae and genus Eugenia which comprises about 1000 species of evergreen trees and shrubs. Some of the old-world Eugenia spp., are now placed in the genus Syzygium. The genus Syzygium is a multipurpose genus with many important species.

The original home of jamun is considered to be India (Singh, 1969), while it is also found in Thailand, Philippines, Madagascar and other African countries. In India, jamun is mainly grown in eastern Himalaya, Kumaon, Gangatic plains, Tamil Nadu, Assam and Andamans. It grows well in marshy land and also in neglected wastelands.

Cultivars/Varieties: There are no improved variety of jamun for commercial cultivation. The most common type grown in north India is known as Raja jamun. This is a large-fruited type having oblong fruits of deep purple colour. A type having large- sized fruits is known as Paras in Gujarat. Another type found in Varanasi has no seed. A selection with desirable traits has been located by the CSA University of Agriculture and Technology at Faizabad. It has been named as Narendra Jamun 6.

Uses

Jamun fruits are deep purple to violet in colour and are, therefore, very attractive. The anthocyanin pigment is responsible for the colour. The products made from jamun are jellies, jams squash, beverage, wine vinegar and pickle. In Goa and the Philippines, jambolans are an important source of wine, somewhat like Port, and the distilled liquors, brandy and “jambava” have also been made from the fermented fruit. Jambolan vinegar, extensively made throughout India, is an attractive, clear purple, with a pleasant aroma and mild flavor.

1. Introduction Plants have played a crucial role in fulfilling human needs for centuries, and among the vast array of plant species, Job’s Tear (Coixlacryma-jobi L), also known as adlay, coix, and Chinese pearl barley, holds significant potential as a crop in the Poaceae family. There are four main varieties of Job’s Tear, including C. lacryma-jobi var. ma-yuen, C. lacryma-jobi var. Puellarum, C. lacryma-jobi var. lacryma-jobi, and C. lacryma-jobi var. Stenocarpa. The Indo-Maynmar region serves as the primary producing area for Job’s Tear millet, with other significant production countries being China, Japan, the Philippines, Myanmar, Thailand, Sri Lanka, and India (Laxmisha et al.,2022). The versatile crop has earned the status of a staple in many regions, not only ensuring food security but also improving the livelihoods of rural farmers. Beyond its nutritional significance, Job’s Tear has garnered recognition for its potential health benefits.

1.1 Introduction Millets are small-grained ancient cereal crops that were renowned as one of the oldest sources of nourishment in prehistoric times. They are believed to have been cultivated since 8000 BC. Apart from providing nutritious grains, these crops are well adapted to the marginal and dryland ecosystems due to their climatic resilience, biotic stress tolerance, and capacity to flourish in the wild. Among the millets, small millets make up a distinct subgroup and comprise of finger millet (Eleusine coracana), little millet (Panicum sumatrense), foxtail millet (Setaria italica), proso millet (Panicum miliaceum), kodo millet (Paspalum scrobiculatum), barnyard millet (Echinochloa frumentacea) and brown top millet (Brachiaria ramosa L.) in India along with a few more cereals like teff, fonio, job’s tears and guinea millet in some other parts of the world. As fine cereals gained popularity after the 1960s, the acreage and significance of these crops began to decrease. In recent years the drastic climate change has made us to focus on underutilized crops.

K ration: It is a lightweight packaged ration of emergency foods developed for the U.S. armed forces in World War II (Plate 371).

Kaiser rolls: A round crusty roll often used for sandwiches (Plate 372).

Kalamata /calamata: It is brine cured black olive grown in Greece.

Kamucha: Tea cider or fermented tea beverages is known as kamucha. The fermentation process take place by the presence of yeast and bacteria

Kanji: Clean, black coloured, crisp and sound product of characteristic flavor prepared by full fermentation (chiefly lactic acid fermentation) of black carrot with 2.5% salt, 1% powder mustard and some amount of water. It is fermented to make ready to serve drink which is known as Kanji. Each kilogram of the grated carrots yields just 7-8 litres of kanji.

Karl Fischer Titration: Karl Fischer Titration is used for estimation of moisture content of foods (low moisture products).

Kasseri cheese: The simple unpasteurized sheep’s milk cheese (sometimes mixed with goat’s milk) is called kasseri. It is popular in Greece. It is made in the shape of wheel, fairly firm and pale yellow (Plate 373). The word kasseri comes from the Turkish kasar which means that it has ability to hold its shape when heated.

a. Dairy entrepreneurship

A dairy entrepreneur is a person who undertakes dairy based activities such as rearing of milch animals, production of milk, processing of milk, manufacture of milk products and marketing of milk and milk products and also involved in buying and selling of other inputs of dairy business. He finds ways and means to create and develop a profitable dairy business. Dairy entrepreneurs see their farming as a business and as a means of earning profits. So they are willing to take calculated risks to make profits and to grow their businesses. They are also motivated to improve dairy production through mechanization and application of technologies in the field of dairy and allied enterprises.

21.1 Introduction
Khoa, as well as mawa or khava, is a partially dehydrated whole milk product that is produced by perpetually heating milk in a karahi over a direct fire while stirring and scraping it with a khunti until it reaches a semi-solid consistency. The pan is removed from the fire once the desired consistency is obtained, and the contents are transformed into a solid mass known as khoa pat. “Khoa is produced by rapid drying cow, buffalo, goat, or sheep milk, or a combination thereof, and must contain a minimum of 20% milk fat.The product is produced by heat desiccating milk to 65–69% solids in an open pan. Khoa has been utilised as a foundation for Indian desserts for centuries. Milk traders and halwais prepare it according to the conventional procedure. You typically require five times the amount of milk content.

21.2 Classification
There are three primary varieties: “pindi” for burfi, “dhap” for gulab jamun, pantooa, and other delicacies, and “danedar” for kalakand. Khoa production has been the most straightforward technique of preserving milk produced in rural areas during the flood season. Pindi, dhap, and Danedar are the three primary varieties of khoa that are prepared throughout the country. Khoa is the foundation for a diverse array of Indian delicacies, such as gulab jamun and other dishes.

SYNOPSIS

We lag in nutritional awareness. The therapeutic values of plant foods, such as vegetables, fruits, grains, legumes, nuts, seeds, herbs, spices and other foods like dairy products, fluids and meats are to be brought to light. The values of important nutrients, may lead to the basis for nutritional education lacking at present. There is need to bring awareness and add to the knowledge of the younger generation. A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.

Kodo millet (Paspalum scrobiculatum) is a resilient and ancient cereal crop native to the Indian subcontinent. Its cultivation dates back to ancient times, with references found in historical texts such as the Brihad Sanhita. This millet species exhibits remarkable adaptability to various agroclimatic conditions, making it well-suited for cultivation across different regions. Kodo millet thrives in a range of soil types, particularly well-drained and sandy soils, which contribute to its successful growth and yield. In terms of nutritional composition, kodo millet stands out as a significant source of protein, dietary fiber, minerals, and antioxidants. Its bioactive components contribute to potential health benefits, including aiding in diabetes management, improving cardiovascular health, and providing essential nutrients. The processing of kodo millet involves various techniques such as puffing, roasting, milling, and fermentation, each influencing its nutritional profile and culinary applications.

1.1 Introduction Millets are one of the world’s earliest food grains, arguably the first cereal grain utilized for household uses. It has been a cherished crop in India for ages and constitutes a staple food for over one-third of the world’s population. Recently ICAR has designated millets as “Shree Anna”. Several types of small-seeded cereals are grouped together as small millets. These crops offer a reliable and affordable harvest from the regions where the primary cereals fail to produce a sustainable yield. Small millets are insignificant in terms of food production, but they are vital as staple foods in their particular ecosystems. Small millets are more than just finger millet (Eleusine coracana) and include kodo millet (Paspalum scrobiculatum L.), little millet (Panicum sumatrense), foxtail millet (Setaria italica L.), proso millet (Panicum miliaceum L.) and barnyard millet (Echinochloa frumentaceae). The rest of the two small millets namely, fonio millet (Digitaria exilis) and teff (Eragrostis tef) are of local significance in Africa. Small millets have a high nutritional value, but also their demand has deteriorated due to a lack of standard processing techniques to compete with fine cereals. Small millets have a huge potential to satisfy our nutritional needs, therefore we must push ourselves and make efforts to enhance its utilization by incorporating them into our daily diet.

Kokum (Garcinia indica L.,) is an evergreen tree found in the tropical forests of India. It is a plant in the mangosteen family (Guttiferae), and is a fruit tree that has culinary, pharmaceutical, and industrial uses. The extract/concentrate of this fruit is called aagal in Konkani and Marathi. It is used for preparation of sol kadhi when mixed with coconut milk. The outer cover of fruit is dried in the sun to get aamsul or kokam. It is used as a souring agent in recipes from Maharashtra. It is a preferred substitute for tamarind in curries and other dishes from Konkan. It is also used in Konkani cuisine, in Gujarat, and some cuisines of South India. As kudam puli, it is an essential ingredient of traditional fish recipes of Kerala. It is particularly seen in Karnataka, Maharashtra, Gujarat, Goa, Kerala, Assam and West Bengal.

Uses

The acidic sweet fruit is mainly used as souring agent for vegetable curry and dal. Sun drying is practiced for preservation. Dried Kokum fruit rinds are widely used in cooking as they impart a sweetish-tangy flavor to the food. The fruits contain citric acid, acetic acid, malic acid, ascorbic acid, hydroxycitric acid and garcinol. Fresh are cut in to halves and the fleshy portion containing the seeds is removed. The rind which constitutes about 50 per cent of the fruit is repeatedly soaked in the juice of the pulp during sun drying. It makes excellent beverage with pleasant flavour. Kokum butter is a product of commerce obtain from seed. It is also used in soap and candle making and suitable for ointment and other pharmaceutical preparations. This fruit is known to reduce obesity and regulate blood cholesterol level.

Lab coat: A loose white coat with deep pockets that is worn in a laboratory or medical office.

Labelling: It means any written, printed or graphic matter that is present on the label, accompanies the food or is displayed near the food, including that for the purpose of promoting its sale or disposal. After packaging, labels are required on the finished products intended for distribution and sale. Labelling can reflect on the quality of the product. It must be clear and informative. Information includes Name of the Manufacturer, Date of Manufacture, Net Weight, Gross Weight, Best before etc. Proper storage is needed for maintenance of the quality. Storage must be done only at recommended temperature, relative humidity, light and air / oxygen and carbon dioxide conditions etc. to maintain the quality of the food product. Label may include tag, brand, and pictorial or descriptive matter, written, printed, embossed, graphic, perforated, stencilled or stamped impressions. It is attached to container, cover, lid, or crown of a food package (Plate 384).

Laboratory: A place equipped for experimental study in a science or for testing and analysis. Broadly, it is a place providing opportunity for experimentation, observation, or practice in a field of study.

Lacquer: It is a colloidal dispersion of a solution of cellulose derivative, resin and plasticizer in solvent and diluents, where in all these constituents dried in air by evaporation of solvents, thus yielding a transparent, hard and water proof film.

13.1. Introduction

Any written, printed, or graphic matter that is present on the label and serves the purpose of promoting the sale of any product is known as food label (WHO). It is believed in general that food packaging and proper labelling plays an important role in food safety as it gives information regarding allergens present, manufacturing site, expiry date, nutritional information etc.

Consumption of unhealthy diet leads to many non-communicable diseases. Therefore, it is the responsibilities of food manufacturers and regulating bodies such as FSSAI and BIS to work hand in hand to provide safe and healthy food to the consumers. Labelling is an important tool useful to disseminate nutritional information to the consumers. Labelling promotes healthy eating among consumers and gives them an option at the time of purchase to choose healthy food. Information in labelling the enables consumers to choose appropriate food according to their diets and lifestyle (Grunert and Wills, 2007). In addition, the information related to nutritional content of the food must be present in such a way that it well understood by every consumer (Wills et al., 2009).

1. Food Labelling

Food labelling is the primary means of communication between the producer and seller of food on one hand, and the purchaser and consumer on the other.

Basic Terminology in Food labelling

‘‘Food” means any substance, whether processed, semi-processed or raw, which is intended for human consumption, and includes drinks, chewing gum and any substance which has been used in the manufacture, preparation or treatment of “food” but does not include cosmetics or tobacco or substances used only as drugs.

‘‘Ingredient” means any substance, including a food additive, used in the manufacture or preparation of a food and present in the final product although possibly in a modified form.

Microscope

A microscope can be defined as an optical instrument consisting of a lens or a combination of lenses for getting magnified images of minute objects. A simple microscope is essentially an ordinary magnifying lens held on an adjustable stand. It can give magnification up to 20 times the size of the object.

A compound microscope consists of two separate lens system, the objective and eye piece (ocular) mounted on a holder known as body tube and with adjustment for illuminating the objects. It gives much greater magnification (100 to 1500 times) when compared to a simple microscope.

1. INTRODUCTION

Amongst the common fermentations employed in food are alcoholic, lactic acid and acetic acid. Lactic acid fermentation is a potent tool of biopreservation of foods by the use of biological means i.e. microorganisms or their metabolites having antimicrobial action. It deals with the extension of storage life and increased safety of edible products by employing natural microflora or their antimicrobial products such as in food fermentation. Though many problems in food processing and microbiological safety of food have diminished, yet these are certainly not eliminated altogether. These include the likelihood of food-related illness and product spoilage in industrialized countries. The increasing consumption of pre-cooked food, prone to temperature abuse, are among the main causes of this scenario. The bacterial pathogens that account for many of these foodborne illness cases include Salmonella, Compylobacter jejuni, Escherichia coli 0157:H7, Listeria monocytogenes, Staphylococcus aureus, and Clostridium botulinum. Until now, approaches to seek improved food safety had relied heavily to find out more efficient chemical preservatives or on the application of more drastic physical treatments (e.g. high temperatures) of food processing. Nevertheless, these types of solutions do have some drawbacks also: the proven toxicity of some of the commonest used chemical preservatives (e.g. nitrites), the alteration of the sensory and nutritional properties of foods (thermal processing) especially recent consumer trends in purchasing and consumption, with demands for safe but minimally processed products without additives.

Lamination and coating techniques are integral to modern food packaging, providing additional layers of protection, functionality, and appeal to the packaging materials. These techniques enhance barrier properties, improve durability, and enable packaging to withstand a range of environmental and mechanical stresses. Lamination typically involves bonding multiple layers of materials to achieve specific characteristics, such as moisture resistance, heat stability, and strength. Coating, on the other hand, adds a surface layer that can enhance properties like grease resistance, sealability, and printability. This chapter explores the various lamination and coating techniques used in food packaging, examining their applications, benefits, and potential limitations.
