A sustainable and healthy food system is one which can provide food and nutrition security for all, in an economical way which is socially and environmentally sound for future generations. Underutilized indigenous and traditional crops can support and strengthen the existing food system, as they are in particular economical and friendly with the environment. Several underutilized indigenous and traditional crops are nutrient dense and adapted to marginal conditions, suggesting that they could be used to champion sustainable and resilient agriculture and food systems for smallholder farmers residing in these environments. The mainstreaming of underutilized indigenous and traditional crops and foods should be recognized for their attributes to make them desirable and to conserve them. In this regard, the fact that value chains for underutilized indigenous and traditional crops are poorly developed at present has created many opportunities to diversify the current food systems. This will create a new employment, market and distribution opportunities.It will also help to combat poverty. It will be if the smallholder farmers and women in rural areas are given the opportunity to utilize underutilized indigenous and traditional crops and re-enter the manistream system. A significant role which is played by the women for the production and conservation of underutilized indigenous and traditional crops offers opportunities for women empowerment through their inclusion in the food system. Promotion of gender equality and empowerment of women is directly linked for strengthening the sustainable food systems that can fight hunger and malnutrition and improve the lives and livelihoods of rural populations. The mainstreaming of underutilized indigenous and traditional crops into the food system would support women to diversify in a sustainable way, feed their own households and to provide nutritious food into the local markets. This will also help in addressing, the Sustainable

Q fever : Q fever is caused by a rickettsia like organism (RLO), a parasitic organism falling between bacteria and viruses. It is a disease that is characterized by high fever, chills, muscular pains, headache, and sometimes pneumonia, that is caused by a rickettsia (Coxiella burnetii) of which domestic animals serve as reservoirs, and that is transmitted to humans especially by inhalation of infective airborne bacteria as in contaminated dust.

Xanthan / Xanthan gum : It is a polysaccharide that is produced by fermentation of carbohydrates by a gram-negative bacterium (Xanthomonas campestris) and is a thickening and suspending agent used in pharmaceuticals and prepared foods. It is also called xanthan. Xanthan is a stabilizer produced by Xanthomonas compestris. Xanthan is not hydrolysed or degraded by humans.

Garcinia mangostana Linn. (GML) belongs to the family of Guttiferae and is named “the queen of fruits”. It is cultivated in the tropical rainforest of some Southeast Asian nations like Indonesia, Malaysia, Sri Lanka, Philippines, and Thailand. The mangosteen fruit is round in shape, dark-purple, 2 to 3 inches in diameter and contains 4 to 8 segments of snow-white, delicious soft flesh. The fruit may or may not contain seeds. Encasing the flesh is a purple skin 6 to 10 cm thick. Because of its taste and medicinal properties, the mangosteen is often called “The Queen of Fruits”. For centuries, the mangosteen has been honored and cherished by the peoples of Southeast Asia. It is a delicately flavoured fruit of temperate zone.

Mangosteen is native to Malaya Peninsula, and mainly cultivated in Malaysia, Indonesia, Thailand, Sri Lanka, Myanmar, India, Vietnam, Philippines, China, California (USA), Hondurus, Panama, Hawaii, Trinidad and Cuba. In India it is cultivated in lower slopes of Nilgiris, Kerala and West Bengal.

Uses

Mangosteen is mainly used as a fresh fruit. Aril of the seed is edible after being boiled in water. The cortex of the fruit contain tannin, and is used as a commercial dye. The rind of fruit is astringent, which is used in chronic dysentery and diarrhea. The bark and young leaves are used to gargle for sore throat. It contains a crystalizable substance known is mangosteen.

Passion fruit, (Passiflora edulis Sims) belongs to the family Passiflora. Within this species, there are two distinct forms, the standard purple, and the yellow, distinguished as P. edulis f. flavicarpa Deg., and differing not only in color but in certain other features. The purple passionfruit is native of southern Brazil. The yellow form was unknown in India until just a few decades ago when it was introduced from Ceylon and proved well adapted to low elevations around Tamil Nadu and Kerala.

Uses

Passionfruit juice can be boiled down to a sirup which is used in making sauce, gelatin desserts, candy, ice cream, sherbet, cake icing, cake filling, meringue or chiffon pie, cold fruit soup, or in cocktails. The seeded pulp is made into jelly or is combined with pineapple or tomato in making jam.

Popularly known as Japanese, or Oriental, persimmon, it is also called kaki (in Spanish, caqui), Chinese plum or, Chinese fig when dried, belongs to the family Ebanaceae. The tree is native to Japan, China, Burma and the Himalayas and Khasi Hills of northeastern India.

Uses

Fully ripe Japanese persimmons are usually eaten out-of-hand or cut in half and served with a spoon. The flesh may be added to salads, blended with ice cream mix or yogurt, used in pancakess, cakes, gingerbread, cookies, gelatin desserts, puddings, mousse, or made into jam or marmalade. The pureed pulp can be blended with cream cheese, orange juice, honey and a pinch of salt to make an unusual dressing.

Phalsa belongs to the family Tiliaceae where only one genus, Grewia, yields edible fruit. The only species of any importance is G. subinaequalis DC. (syns. G. asiatica Mast), long referred to in literature as Grewia asiatica L. Phalsa is the most used vernacular name in India, where there are a number of local names. The plant is called falsa in Pakistan. Phalsa is commercially cultivated in India in states of Punjab, Haryana, Rajasthan, Uttar Pradesh and Madhya Pradesh.

Cultivars/Varieties: Two distinct types, viz. Tall and Dwarf were recognized in Hisar and dwarf type was found to be more productive. Some call them as ‘Local’ and ‘Sharbati’.

Uses

The fruits are eaten fresh as dessert, are made into syrup, and extensively employed in the manufacture of soft drinks. The fruit is used in making juice and squash. The bark is used as a soap substitute in Burma. A mucilaginous extract of the bark is useful in clarifying sugar. Fiber extracted from the bark is made into rope. The wood is yellow-white, fine-grained, strong and flexible. It is used for archers’ bows, spear handles, shingles and poles for carrying loads on the shoulders. Stems that are pruned off serve as garden poles and for basket-making.

The rambutan is native to Malaysia and commonly cultivated throughout the archipelago and southeast Asia. Though a close relative of the lychee and an equally desirable fruit, this member of the Sapindaceae is not nearly as well-known. Botanically, it is Nephelium lappaceum L. (syns. Euphoria nephelium DC.; Dimocarpus crinita Lour.). In the vernacular, it is generally called rambutan (in French, ramboutan or ramboutanier; in Dutch, ramboetan); occasionally in India, ramboostan.

Sapota is a hardy, evergreen small tree belonging to the family Sapotaceae. It is known botanically as Manilkara zapota van Royen (syns. M. achras Fosb., M. zapotilla Gilly; Achras sapota L., A. zapota L.; Sapota achras Mill.). Sapota, sapodilla, chiku is a hardy tropical fruit tree. In India, it is mainly cultivated for its delicious fruits. The sapodilla is believed native to Yucatan and possibly other nearby parts of southern Mexico, as well as northern Brazil and Northeastern Guatemala. But now its cultivation is extensive in India (Morton, 1987).

In India, the procurement and disposal of food grains are governed by several guidelines to ensure food security and fair market practices. Procurement is typically managed by government agencies like the Food Corporation of India (FCI), which purchases grains directly from farmers at minimum support prices (MSP) to stabilize market prices. Farmers are encouraged to sell their produce through designated government procurement centers, ensuring fair prices.
The quality of food grains is a key consideration in procurement. Grains are tested for moisture content, cleanliness, and pest infestation before being accepted. Once procured, the grains are stored in government warehouses, with regular inspections to prevent spoilage and pest damage. For disposal, food grains are distributed through public distribution systems (PDS) to ensure availability to consumers at subsidized rates. Any surplus grains may be sold in open markets, or occasionally exported, to maintain a balance in supply and demand. Effective management ensures food security and minimizes wastage.
PROCUREMENT POLICY OF WHEAT AND RICE
State Government agencies and the Food Corporation of India (FCI) are responsible for purchasing wheat and paddy within the designated period, ensuring that the products meet the prescribed Fair Average Quality (FAQ) specifications and are procured at the Minimum Support Price (MSP) for the Central Pool. This procurement supports the distribution of food under the National Food Security Act (NFSA) and other welfare schemes (OWS).
The Government of India (GoI), in consultation with State Governments and FCI, finalizes procurement estimates for wheat and paddy before each marketing season. These estimates are based on anticipated production, marketable surplus, and the agricultural crop pattern. The procurement of paddy and wheat is carried out under both the Decentralized Procurement System (DCP) and the Non-DCP system.

Food preservation has evolved from traditional household practices to an interdisciplinary field incorporating microbiology, biochemistry, engineering, biotechnology, packaging, nanotechnology and digital intelligence. The book demonstrates that food stability can increasingly be achieved without excessive reliance on synthetic chemical preservatives. Effective preservation requires control of microbial growth, enzyme activity, oxidation, moisture, temperature and environmental exposure while protecting sensory and nutritional quality. Traditional practices remain scientifically valuable, while thermal, non-thermal, biological, packaging and digital technologies offer new possibilities. Future food systems will depend on carefully designed combinations of these approaches to improve safety, shelf life, sustainability, traceability and consumer acceptance while overcoming cost, regulatory and scalability challenges.

30.1 Introduction
Every food processing facility, especially those that produce several products, generates trash in various forms. The food products are rich in carbs, proteins, lipids, and mineral salts. During the process of flushing and washing various equipment, nutrients are released into the drainage, promoting the growth of both anaerobic and aerobic bacteria. Consequently, the water that is flushed might have a highly unpleasant smell and could become a challenge for disposal in the municipal sewer system.

30.2 Definition of Waste Management
Waste management encompasses the collection, transportation, processing, recycling or disposal, and oversight of waste materials.

30.3 Types of Wastes in a Food Processing Plants
Waste produced in food processing plants can be categorized based on their form and origin, whether they are avoidable or unavoidable, their value, or their potential for reuse.

30.3.1 Based on the forms: Wastes based on forms can be classified as
1. Solid wastes,
2. Liquid wastes,
3. Oily wastes,
4. Gaseous wastes/water vapors.

Jaggery: Raw brown / unrefined brown sugar in lump made from palm sap (Plate 365).

Jam: A preserved product prepared on boiling pectin contained in fruit pulp with required amount of sugar, water and acid to a reasonably thick consistency, firm enough to hold the fruit tissues in position (Plate 366).

Jam pack: The packing of the commodity tightly or in excess is called Jam pack.

Jamaica rum: Heavy bodied rum made by slow fermentation and marked by a pungent bouquet.

Jamboline: A type of glucose found in the jamun fruit help in cure of the diabetes in the patients.

Jelly: A product prepared by boiling clear extract of fruits with sugar. It should be transparent, well set, and tender enough to quiver but not flower and when cut; it should retain its shape and show a clean cut surface (Plate 367).

Q10 value: The number of times a reaction rate change with a 10oC change in temperature is called Q10 value. If reaction rate doubles with 10oC change in temperature, Q10 = 2. It is also called temperature quotient.

Q-enzyme: It is a branching enzyme responsible for formation of 1-6 bonds in amylopectin.

QHV process: It stands for Quality Has Value Process.

QO2 : It is a unit for measurement of respiration. Or It is the oxygen uptake in microlitres per milligram on dry weight per hour.

Quailing: In this practice the oranges are kept in the baskets in which they are harvested to allow the fruit to loose little moisture. It is done for a couple of hours before transport to packhouse. This practice would allow the fruit to lose a little moisture which is called quailing. This operation is done for oranges to prevent Oleocellosis.

Qualitative measurement: It is a subjective / objective measurement of the quality of the product for presence of certain compound. It gives the idea of the presence or absence of the particular compound. It deals with the nature of the substance and not its amount or quantity.

Jaggery: Raw brown / unrefined brown sugar in lump made from palm sap (Plate 142).

Jam: A preserved product prepared on boiling pectin contained in fruit pulp with required amount of sugar, water and acid to a reasonably thick consistency, firm enough to hold the fruit tissues in position (Plate 143).
