After modified starch is processed by an extruder, its physical, chemical and structural properties will change significantly, which is mainly related to the high temperature, high pressure, high shear force and mechanical action during the extrusion process. The following are the main changes and effects of modified starch during extrusion processing: Structural changes
The difference between pregelatinized starch and modified starch Generally speaking, pregelatinized starch is a kind of modified starch with relatively simple processing and wide application, that is to say, pregelatinized starch is also a kind of modified starch. The modified starch we usually refer to refers to the changes in some of the original properties

Modified starch is based on the inherent properties of natural starch. In order to improve the performance of starch and expand its application range, it adopts physical, chemical or enzymatic treatment to introduce new functional groups on starch molecules or change the size of starch molecules and starch particles. This changes the natural properties of
