Acetylated Distarch Glycerol is prepared by treating starch with acetic acid anhydride and glycerol. This results in a starch that is resistant against stirring and high temperatures and with a high stability after cooling. They are prepared by physically, enzymatically, or chemically treating native starch, thereby changing the properties of the starch. 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.
