一般描述：Starch is a natural storage carbohydrate polymer produced by plants and varies in its form and function. It is considered as a macroconstituent of food and serves as an energy source. It is renewable and can be biodegraded. Glucose polymers, amylose and amylopectin forms starch molecule. Starch influences the food structure and quality. It is a native high amylose corn starch. 应用：Starch from corn has been used:in the preparation of test diet pelletsto study the activity of recombinant β-amylase (BAM) proteinsto study the amylopectin molecular structures and functional properties
