India is the largest producer of guar and contributes about 80% of total guar and guar gum production in the world.Guar Gum is an important ingredient in producing food emulsifier, food additive, food thickener and other guar Gum products.
Guar or cluster bean (Cyamopsis tetragonoloba) is believed to have originate from Africa but it's been grown throughout southern Asia. India and Pakistan have distinct advantage of agro-climatic conditions for the cultivation of guar though it is also successfully grown in U.S.A., South Africa,Australia, Brazil, Zaire and Sudan. Guar is a drought-tolerant, multi-purpose annual arid legume crop cultivated mainly during Kharif season and used for extracting gum from seeds, animal fodder from vegetative part, and also used as green manure. In India the major guar producing areas are Rajasthan, Gujarat and Haryana. The major producing areas are also important processing areas of guar and its derivatives.
Guar is the source of a natural hydrocolloid, which is cold water soluble and form thick solution at low concentrations. The guar seed consists of three parts: the seed coat (14-17%), the endosperm (35-42%), and the germ (43-47%). It is from the endosperm that guar gum is derived, which is the prime marketable product of the plant. This spherical shaped endosperm contains significant amounts of galactomannan gum (19 to 43% of the whole seed), which forms a viscous gel in cold water. Like other legumes, guar is an excellent soil-building crop with respect to availability of nitrogen. Root nodules contain nitrogen-fixing bacteria and crop residues, when ploughed under, improves yields of succeeding crops
The Guar Industry has evolved from being a used for domestic and ruminant feed purpose to finding used in industry. Owing to new technology, research and development the natural gum property of guar had varied applications from food, pharma industry to oil Industry. The guar industry is poised to grow and develop owing to high focus on research in Universities and technical institutes of the world. The keen interest of industry, government and community will result in cohesive partnership to foster profitable global value chain of guar gum
The processing of guar gives three products mainly viz. guar splits, churi and Korma. Guar split is used as a main products for different industrial uses while Churi and Korma are used as cattle feed.
