Starch can be regarded as a high polymer of glucose. Starch in addition to food, the industrial system for dextrin, maltose, glucose, alcohol lamps, but also for the preparation of printing pulp, textile sizing, paper, plastic, tablet compression drugs. May be corn, sweet potato, wild acorns and puerarin and other starch-derived material derived.
Starch is stored in the plant nutrients, stored in seeds and tubers, various types of plants in the starch content is high, 62% ~ 86% of the starch in rice, wheat starch 57% ~ 75%, corn Starch 65% to 72%, potato starch is more than 90%. Starch is an important part of food, chewed rice and so feel a little sweet, it is because the amylase in saliva hydrolysis of starch into a disaccharide - maltose. Food into the gastrointestinal tract, but also by pancreatic secretion of saliva amylase hydrolysis, the formation of glucose is absorbed by the small intestine wall, a human tissue nutrients. Partial hydrolysis of amylopectin produces a mixture called dextrin. Dextrin is mainly used as food additives, glue, paste, and for paper and textile manufacturing (finishing) and so on.
Potato starch is commonly used in the family of starch, the potato is ground, rub wash, precipitation made of. Features: sticky feet, delicate texture, color white, shiny than mung bean starch, but the poor water absorption.
