Starch (C6H10O5)n, the principal reserve poly Saccharide in plants constitutes substantial portion of human diet. It is the principal components of most seeds, tubers, and roots, and is produced commercially from Wheat, Rice, Tapioca, Potato, Sago, and other sources. Starch is a mixture of linear (amylase) and branches (amylopection) polymers of alpha D glucopyranosyl units. Natural starch occurs usually as granules composed of both linear and branch starch molecular. However, some starches are composed only of branched molecule and there are termed waxy starches because of the Vitreous sheen of a cut sheet surface. The roots of tapioca plant (Manihol uteillissima) forms one of the major sources of starch ranking next is potato in the consumption Undamaged starch granules are insoluble in cold water but impipe water reversibly and swell slightly. Hydrolysis of starch is an important industrial reaction which is accomplished by acid, enzymes or both. Starch gives a characteristic blue color with Iodine. This characteristic blue colour has burned both over qualitative and quantitative test for starch in various systems. Cassava has many advantages for starch production: High level of purity; Excellent thickening characteristics; A neutral (bland) taste; Desirable textural characteristics; A relatively cheap source of raw material containing a high concentration of starch (dry matter basis) that can equal or surpass the properties offered by other starches (maize, wheat, sweet potato and rice). Uses Unmodified starch is mainly is nonfood application in the naming adhesive and paper Industries. Unmodified starches are used for the manufacture of gun candies because they form hot concentrated pastes that gel firmly on cooling. Heat treated starches are used in food applications to bind and carry flavors and colors. Swelling agents are made from starch by enzymatic or acid ferment. Starch derivatives like cation starch, starch phosphate and starch acetate has numerous uses. ? Market Survey Global starch consumption is projected to reach 133.5 million metric tons. Rise in per capita consumption, and growing demand for starch products from developing nations translates into a bright outlook for the sector. Starch end use applications have grown in number over the years, and now include diverse applications ranging from food and beverages to medicine, cosmetics, pharmaceuticals and more. Usage of starch by the food industry is being fueled by the increasing number of government policies stipulating the usage of natural substances in food products. With the increasing demand for low fat and low calorie food, many food companies are replacing fats with gums and carbohydrates, such as starches and hydrocolloids. The major cassava starch and flour importers are, by order of importance, China, Japan, Malaysia, Indonesia, Singapore, the United States and the Philippines. In India also, production of starch from potatoes is limited due to availability of cheaper sources of starch such as maize and tapioca. Few Indian Major Players are as under:- Amaravati Agro Ltd.
