The Essentials and Many Uses of Starch

Important uses of starch as food and its significant industrial usages.

Starch is the food material that is stored in plants and can be found in seeds, in roots, in tubers or in stems. It provides food for growing seeds and for plants during their resting period. Starch is an important food for people, too. It is the most important carbohydrate in the human diet. Starch, scientifically known as amylum, is the common name for a white, granular or powdery, odorless, tasteless carbohydrate. One notable characteristic of starch is – it does not dissolve in cold water, alcohol or ether. It does dissolve in hot water.
