Starch is a carbohydrate consisting of a large number of glucose units joined together by glycoside bonds. This polysaccharide is produced by all green plants as an energy store. It is the most important carbohydrate in the human diet. Starch occurs in nature in many ways. It is contained in such staple foods as potatoes, wheat, maize (corn), rice, and cassava. Potato Starch is one starch derived from potatoes in the process of mechanical separation of starch grains from other parts of potato, washing out, purification, drying and sieving. This starch is intended both to food and technical applications.
