Curing- Curing is a process in which produce is subjected to undergow through a special treatment to get the quality product.

Abstract

Sikkim is part of the eastern Himalayan hotspot. Rich biological diversity of the region is owing to its wide range of topography, varied climatic condition and high annual precipitation, inhabited by three major ethnic communities, the Lepchas, Bhutias and Nepalese. With its unique ethno-cultural diversity and equally rich Phyto-diversity, the region holds an immense ethno-botanical knowledge and potential. The collection of food, fodder, fuel wood, timber, herbs for folk medicine from wild is an integral and deep-rooted cultural component and for sustaining socio-economic condition of the people. Medicinal plants of this region have potential for value addition as well as domestication. The folk medicine practices of three ethnic groups are different, but in general there are strong beliefs system in relation of folk medicine with supernatural forces and deities; local people consider its mountain peaks, forest, lakes as sacred hence it helps in sustainable management of its natural resources traditionally. Developments activities, urbanization, overexploitation of important plants and not giving due importance to the traditional knowledge in the past decades leads to the potential depletion in wild and that bring concern for their conservation. A proper strategic plan is needed for conservation of these valuable resources and promoting the indigenous traditional knowledge for sustainable development. Conservation-linked with people participation has been initiated in Sikkim through Sikkim State biodiversity board (SSBB), with its biodiversity management committees (BMCs), and local activist and stakeholders. The research institution of the region and researcher from outside has contributed immensely in documentations of the ethno-botanical knowledge and phyto-diversity of this region. This chapter reviews the current status of traditional ethno-botanical knowledge system of Sikkim state and highlights the current scenario of biological diversity; conservation practices, threats and challenges.

Introduction

Vegetables are the vital sources of minerals, vitamins and dietary fibres and play an important role in supplying nutrition to human health. Vegetables require comparatively lesser quantities of agro-inputs to grow. Vegetables are rich source of vitamins, minerals and plant fibres which provide food and nutritional security. These also generate high income and employment, particularly for small farmers. Vegetables being a rich and cheap source of vitamins and minerals, occupy an important place in the food basket of Indian consumers, a majority of whom are vegetarian. This persistent vegetarianism coupled with rising per capita income is fuelling a rapid growth in consumption of vegetables. Presently, India is producing more then 70 types of vegetables which are capable of meet out the economic and nutritional requirement of the country (Table 1). There has been a revolution in the production of vegetables in the country in the last four decades.

Current Trends in Fruit Exports from India

Fruit culture in the Indian subcontinent dates back to the Harappan civilization when datepalm, pomegranate and lemon were domesticated. Fruits such as aonla, bael, jackfruit, karonda, phalsa, mango, pomegranate, almond, walnut and pistachio are mentioned in Charaka Samhita (300 BC) and Sushruta Samhita (400 BC), the oldest known texts on ayurveda. Owing to diverse agro climatic conditions, India can produce a wide range of tropical, subtropical, arid and temperate fruits. In the past few decades, India had made rapid strides in fruit production and is currently the second largest producer of fruits in the world, next only to China. The annual production is estimated to be about 81 million tonnes for about 12.6% of the total world production. However, India’s share in the global export of fresh fruits is less than 5 per cent. The major fruits exported in terms of quantity are grape, mango, banana and pomegranate. In value terms, grapes and mango earn the maximum foreign exchange for India.

6.1. Origin and distribution

• The plant originated in the Tarai region of Uttar Pradesh, India, and at present it is cultivated in Burma, Ceylon, China, Australia and the Pacific Islands.

• Optimum temperature is 26° to 37°C.

Curry leaf (Murraya koenigii Spreng. Syn. Bergera koenigii Koen (N.O Aurantiaceae), Chaleas koenigii Curz ex. Swingle) is a perennial leaf vegetable. It belongs to family Rutaceae. Its genus name ‘Murraya’commemorates John Adam Murray, Professor of Botany at Gottingen and editor of many of Linnaeus’s works. (Fyson, 1977).

Origin and Distribution

The crop originated in the tarai tract of Uttar Pradesh (India), in the foothills of the Himalayas. Wild forms with less pungent leaves are seen along the plains and hills of Himalayas extending from Kumaon to Sikkim, in Bengal, Assam, Deccan plateau and in Western Ghats. At present, it is cultivated in Myanmar, SriLanka, China, Australia and Pacific Islands. The curry leaf grows throughout India including the Andaman Islands up to an altitude of 1500 m amol (Wealth of India, 1962). Dastur (1970) recorded its wild form in Garhwal hills in Uttaranchal, Sikkim, Bengal, Assam, Central India, Western Ghats, Tamil Nadu and Kerala.  Used as a flavourant and as a leaf vegetable by the early inhabitants, Dravidians, curry leaf was introduced to Southern India when the Dravidians moved southward after the arrival of Aryans from Persia. It is a backyard crop in many of the South Indian homesteads.  The spicy leaves of plants are used extensively for seasoning and flavouring dishes.

English name : Curry leaf
Botanical name : Murraya koenigii (Linn.) Sprengel
Family : Rutaceae
Chromosome number : 2n = 18
Centre of origin : India
Curry leaves come from the aromatic, often deciduous herb or small tree Murraya koenigii (Linn) Sprengel, which belongs to the Rutaceae family. They are widely used in cooking to enhance the flavour of dishes, although their nutritional value is often ignored, as they are typically discarded after being used as a spice.
The fresh weight composition of curry leaves includes 66.3% moisture, 6.1% protein, 1.0% fat (ether extract), 16.0% carbohydrate, 6.4% fibre, 3.1% iron, 4.2% mineral matter, 810 mg of calcium, 600 mg of phosphorus, 12,600 IU of carotene (vitamin A), 2.3 mg of nicotinic acid, and 40 mg of vitamin C per 100 grams. While the leaves lack thiamine and riboflavin, they are a rich vitamin A and calcium source. However, their nutritional availability is reduced due to the high oxalic acid content (1.35%, with 1.15% being soluble oxalates).

Genus Annona belonging to the family Annonaceae, contains more than seventy species of woody shrubs and trees, all of which produce aggregate fleshy fruits. Of these only a few produce edible fruits of commercial importance. Of all, Annona squamosa L. is probably the most popular fruit. It is also known as ‘Sitaphal’ or ‘Shariffa’. These can withstand drought better than many other fruit trees. Other species of the genus Annona providing edible fruits are A. reticulata L., A. muricata L., and A. cherimola L.

Custard Apple (Annona squamosa Linn.)

The custard apple, Annona squamosa L., also known as sweet-sop or sugar apple, is almost entirely eaten as a dessert fruit. Its pulp may be mixed with milk to form milk shake or made into ice-cream. The pulp has a pleasant texture and flavour. Several products like -squash, nectar, pulp butter, syrup, jam can be made from the pulp.

Custard apple is native to tropical America (Mexico). It is cultivated in Australia, Brazil, Chile, Egypt, India, Israel, Myanmar, Mexico, Philippines, Spain, Sri Lanka, South Africa, West Indies, USA and Cuba. In India it is popular in Andhra Pradesh, Madhya Pradesh, Tamil Nadu, Karnataka, Maharashtra, Uttar Pradesh, Orissa, Asssam, Bihar and West Bengal.

Cultivars: The cultivars vary in their shape, size, colour and eating quality. Some of the cultivars are Balanagar, Sangareddy Local, Chittorgarh, Barbados, British Guinea, Mammoth, Red Sitaphal, Yellow Sitaphal, Custard Apple Selection-1, Custard Apple Selection -2. Arka Sahan is a hybrid developed by ICAR-IIHR, Bangalore.

Mealy bugs: Ferrisia virgata, Planococcous lilacinus, P. pacificus, Maconellicoccus hirsutus, Perisopneumon ferox: Pseudococcidae

The fruit is seen covered with a mealy coating due to colonies of small reddish-white mealy bugs. They also infest leaves, shoots and buds. Due to sucking of sap by nymphs and adult female mealy bugs, fruits remain small in size and become shrivelled. Large number of mealy bugs is seen in the tip of the petiole abd also on the grooves of fruits epicarp. The fruit also becomes blackish due to the development of sooty mould.

34.1. Aim

To conduct cut out analysis of canned fruits and vegetable products.

34.2. Theory

Cut out examination of canned products is conducted to evaluate the product whether confirming to FSSAI standards or not. Canned fruit and vegetables are evaluated for presence of vacuum or pressure in the can, drained weight, total soluble solids, presence or absence of preservative, internal condition of can product contents and presence or absence of fermentation for ensuring microbiological safety.

ABSTRACT

Cultivation of mat grass (Cyperus pangorei Rottb.) is valuable and expensive products can plays an important role in rural areas such as Sabong and Pingla in Paschim Medinipur of West Bengal in India. Mat grass plays an act to fill the empty employment field to the resource of poor farming community to support and secured their livelihoods and maintain the economical balance of their area. This grass usually cultivated by the poor and marginal farmers. The mat sticks are used to make various household utility items, such as floor and bed mats and other attractive goods like bags, purse, TV covers. Now a days the products prepared from this grass is exported to different countries. Mat sticks are attractive durable and is eco-friendly substances which easily gets decomposed by organisms, does not create any environmental hazards and gets more profit as compared to growing rice per annum. Even an old man or woman in rural areas can earn a net income of about Rs.120 to Rs150 per day. Major focus of the study is to establish the scientific principles behind processing, separation of clum strand, texture and strength properties of the mat fibers and increase mat production which leads to improve the economic condition of rural people.

Abstract

Dactylorhiza hatagirea (D.Don) Soo, a plant species native to Indian Himalayas (Badola and Aitken, 2003; Ved et al., 2003), is one of 110 orchids known for their medicinal properties (Jain 1991; Lal et al., 2004). Known earlier as Orchis latifolia auct. non Linn., D. hatagirea has traditionally been used in indigenous system of medicine in India as ‘Hatajari’ or ‘Salam Panja’. The plant has therapeutic, ornamental and ecological significance (Gupta et al., 1998; Vij et al., 1992; Kala, 2000a). Due to over extraction from nature for medicinal use, the species has become threatened and categorized as critically endangered species (Ved and Tandon, 1998; Kala, 2000b; Ved et al., 2003; Bhattarai et al., 2014). This contribution provides insight into the botanical background, distribution, medicinal importance, threat status, cultivation and commercial aspects, and strategies for its conservation and sustainable utilization.

Introduction
Among flowers, the rose enjoys the greatest adorable position over the world. In real sense, rose almost hypnotised the man most by its colour and fragrance. Apart from its aesthetic value, the roses are of high economic benefits, and religious significant. Besides, it finds it place in art and culture from times immemorial. The rose thus merits pride of place as the ‘Queen of flowers’.
Origin
The damask rose is originated in ancient Persia (now Iran), and later on spreading over Europe and Northern Africa. Further, widespread farming of R. damascena for rose oil manufacturing began in Turkey and Bulgaria. Many countries of the world grow scented roses for extraction of the volatile essential oil. The genus Rosa grows wild in many parts of the temperate and sub-temperate regions. The major growing countries are Bulgaria, France, Italy, Turkey, Russia, China and India. Bulgaria is the principle European country for supply of rose oil to the world market. Among different species, Rosa centifolia Linn. is largely grown in France and Italy, whereas Rosa
damascena Mill. in Turkey, Bulgaria, Russia and Persia. Rosa damascena Mill. was first introduced successfully in middle east countries during 1680, resulting in the establishment of entire area as ‘Valley of flowers’. It belongs to family rosaceae.

The term dandruff includes several different conditions of the scalp. There is scaling in which the entire scalp may be covered with loose dry scales. When the hair is combed or brushed, or when the scalp is scratched, these scales fall like snow on the shoulders. Often there is itching, as well, and the scalp may be red from scratching.

What is at first thought to be dandruff may later prove to be some other conditions, such as. seborrhoeic dermatitis, or worse still psoriasis and even neurodermatitis.

Neurodermatitis : It is a chronic type of itching and inflammation of the skin. The itching area may be in some localized spot or it may extend over large areas of the body. The condition may even develop in infants. It may disappear after the age of two and return in the early teens of later. The condition is more often seen in those who suffer from fever, hives and asthma. True cause is not known for most of the people are allergic to many things. Many of them are tense and restless and are troubled with a dry skin. They are hypersensitive and are often given to itching, especially in the bend of elbow or behind the knee. The constant scratching leaves deep scratch marks and causes thickening and furrowing of the skin.

Morphological characteristics

The plant is a monoecious undershrub that grows up to 3.5 metres tall and has serrated leaves and stiff branches that emerge from the root. Lower branches feature big, typically broad, elliptical, three- to five-lobed leaves with rounded bases, while above branches have small, lanceolate leaves. Petioles range in length from 5 to 15 cm.

Floral characteristics

The flowers are unisexual. The calyx of male flowers is globose, 2.5 mm long, four to five partite, glabrous or slightly pubescent, membranous, finely mottled with a disc of six glands, and glabrous or slightly pubescent. There are approximately 20 stamens in each flower. Sepals are ovate-lanceolate and glabrous, and the disc is roughly 2.5 mm in diameter in female flowers. Fruit is a three-lobed capsule that is around 8–13 mm long and hairy. Seeds contain an oily endosperm and are speckled and smooth. Flowers bloom in January–February, followed by fruit that mature a month later.

Distribution

The species grows in tropical and subtropical places with rainfall of around 1000 mm, such as the Himalayan foothills, Kashmir to the Khasi hills, and especially in the Vindhyas southward. In North and East Bengal, Chhota Nagpur, and peninsular India, it is fairly frequent.

Date-palm (Phoenix dactylifera L.). belongs to family Palmae and is the most common tree of desert and dry areas. Date palm is one of the oldest trees known to man kind. Date-palm is believed to have originated in the countries around Persian Gulf. It is extensively grown in Iraq, Iran, UAE, Saudi Arabia, Algeria, Egypt, Libya, Yemen, Mauritiana, Morrocco, Tunisia, Baharin, Sudan, USA, Spain, Australia, Pakistan, South Africa, Somalia, Oman and some parts of the South America. Date is a staple food of the people of the Western Iraq and North Africa. In India, it has been believed to be introduced by soldiers of Alexander the Great in 4^th century B.C. In India it is commercially cultivated in Rajasthan, Punjab, Hariyana and Gujarat.

Cultivars: Deglet Noor, Halawy, Khadhrawi, Hayani, Majhul, Zahidi, Khalaeh.

Uses

Date palms produce many products that are useful to human beings. The primary product is the date fruit, which can be eaten fresh, dried, or in various processed forms. In North Africa and the Middle East, some dates are harvested and consumed during the Khalal stage, when the fruit are still very astringent with a high tannin content (Dowson and Aten, 1962 ; Glasner et al., 2002; Kader,1992). Dates can be used in cereal, pudding, bread, pressed cakes, cookies, candy bars, ice cream, and date shakes (a California specialty). Date fruit also can be made into juice, vinegar, wine, beer, sugar, syrup, honey, chutney, pickle, paste, dip, and food flavoring (Barreveld, 1993; Glasner et al., 2002).

It is said that there are as many uses of dates as there are days in a year. The trunk and wood of date palms can be used as timber, wood, or fuel. Fiber from the trunk and leaves can be made into bags, baskets, camel saddles, cords, crates, fans, food covers, furniture, mats, paper, ropes, trays, and twine. Dried bundles of leaves (‘‘Barusti’’) can be made into shades, roofs, separating walls, and enclosures. Ribs of the leaves can be used to build boats (small fishing boats called ‘‘Shasha’’) or fishing traps. The base of the leaves and fruit stalks can be used for fuel. The pith of the palms can be made into date palm flour. Terminal buds (palm heart) can be eaten as a salad or as a cooked vegetable. Date seeds can be used as feed for livestock or strung as beads for decoration. Oil from date seeds can be manufactured into soap (Chao and Krueger, 2007). Dates are considered a balanced and healthy diet and have several medicinal uses. Leaves are source of fibre used for making ropes baskets and cordage. Walking sticks are made from leafstalk.

Introduction
Davana (Artemisia pallens Wall.) is one of the important aromatic herb found abundantly in humid habitats in the plains all over India. It is popularly known as sage brush, worm wood and mug word. The davana (Artemisia pallens) is a small to medium height; annual and herbaceous aromatic plant. This herb is erect, and grow up to 60 cm height. Its leaves are highly divided and bears small size yellow coloured flower. Its leaves and stem found protected with greyish-white tomentum. The leaves are lobed, alternate, and petiolate.
Origin & Distribution
It is native to southern India, where it is traditionally grown in Karnataka, Maharashtra, Kerala, T.N., and A.P, growing widely in tropical to subtropical
plains as Rabi season crop. It also found growing in wild form in the Himalayan region in the Simla, Kashmir valley, and Nainital hills. It is widely used by Ayurvedic healers to balance the three energies. It is an erect growing
plant up to 60 cm height. It does not grow wild, but grown as a garden plant in South India. It is a crop of irrigated conditions; and do well when planted in November-December, yielding significantly higher oil yield in comparison to crop planting in July-August. The crop should be harvested 2-3 inches above ground level during bright sunny days at 50 percent flowering stage to have high oil content and oil yield.

Semilooper: Thysanoplusia(Plusia) orichalcea : Noctuidae

Bluish green or grey coloured eggs are laid singly on lower surface of leaves.The larvae are semi loopers and feed voraciously on leaves and cause defoliation of the plants.

6.1. Origin and distribution

• Common in Kashmir Valley, Shimla and Nainital Hills.

• Commercially cultivated in Karnataka, Maharashtra, Kerala, Tamil Nadu and Andhra Pradesh

6.2. Economic importance

• Sweet worm wood or annual worm wood

• Chemical constituents - Artimisinin

• Commonly used in garlands, bouquets and religious offerings in most part of the country.

• Leaves and flowers contain essential oil valued for its exquisite and delicate aroma and is used in high grade perfumes and cosmetics.

48.1. Aim

To conduct practical on drying of fruits

48.2. Theory

Drying generally refers to the method of removal of moisture from the food under natural condition such as sunlight and wind for example open sun drying, shade drying etc. Dehydration refers to a process of removal of moisture by application of artificial heat under controlled conditions of temperatures humidity and air flow. It also represents drying of agricultural commodity to dry state. For drying, single thin layer of fruit and vegetables, either whole or sliced after primary pre-treatments is spread on the trays which are then placed inside the dehydrator or in the open sun for drying. In the dehydrator initial temperature is generally kept at 43oC which is then gradually increased to 66-71oC for fruits.
