Research on Starch Modification
2022.02.14
Starch is a natural macromolecular compound of polysaccharide substances obtained by polycondensation of α-glucose. It is the most abundant renewable substance in nature. It can be degraded and will not pollute the environment. There are a large number of reactive hydroxyl groups in its molecular chain, which provides a structural basis for the modification of starch. Modified starch is based on the inherent characteristics of natural starch. In order to improve the properties of starch and expand its application range, physical and chemical treatments are used to introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules. , thereby changing the natural properties of starch to make it more suitable for certainapplication requirements. Nowadays, there are more and more varieties of modified starch, more and more uses, and are widely used in various fields, which brings great convenience to our life and work.
