Modified starch is based on natural starch, in order to improve the performance of starch, expand its application range, use physical and chemical treatment, introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules, thus changing starch natural characteristics to make it more suitable for the requirements of certain applications. As one of the important excipients of the industry, modified starch can be widely used in paper, food, textile, construction, medicine and other industries.

Modified starch can be divided into physical type, chemical type, enzymatic type and compound type. Extrusion modified starch and conventional pre-gelatinized starch original starch gelatinized by high temperature treatment are common types of physical modified starch

Modified starch (pregelatinized starch) production line selects Corn starch, cassava starch, Potato starch, etc. as the main raw materials according to different product needs. After adding appropriate amount of water, the starch will be modified through the high temperature and pressure in the extruder cavity and the shearing effect of twin-screw on the materials, introducing new functional groups on the starch molecules or changing the size of starch molecules and the properties of starch particles,

Modified starch ether is a white fine powder obtained from natural plants through highly modified etherification reaction and spray drying. It does not contain plasticizer and is completely different from domestic starch or modified starch

The purpose of starch modification is to meet the needs of various industrial applications. With the development of science and technology, the modified starch production equipment has also made great progress.
