Modified Starch Machinery

Modified Starch Machinery

Modified starch, also called starch derivatives, is prepared by physically, enzymatically, or chemically treating native starch to change its properties. Modified starches are used in practically all starch applications, such as in food products as a thickening agent, stabilizer or emulsifier; in pharmaceuticals as a disintegrant; as binder in coated paper. They are also used in many other applications.

Starches are modified to enhance their performance in different applications. Starches may be modified to increase their stability against excessive heat, acid, shear, time, cooling, or freezing; to change their texture; to decrease or increase their viscosity; to lengthen or shorten gelatinization time; or to increase their visco-stability.

Modified starch variety:

Oxidized starch

Cross-linked starch

Phosphate starch

Acetate starch

hydroxypropylated starch

acetylated distarch phosphate
