Acetylated double starch adipate, also known as double denatured glutinous rice powder, is a white to similar white powder, odorless, tasteless, insoluble in cold water and ethanol, and turns reddish brown in the presence of iodine. After the starch is co heated with water, it turns into translucent colloid under certain conditions. Compared with the original starch, its solubility, swelling power and transparency were significantly improved; The aging tendency was significantly reduced and the freezing stability was improved. Acetylated double starch adipate is a widely used chemical modified starch. The product not only has the inherent characteristics of glutinous rice, such as scent, glutinous, sticky, but also has the characteristics of good aging resistance and formability of modified starch, and can be applied to the processing of cakes such as sweet potato and green tea. Acetylated double starch adipate is a composite modified starch obtained by crosslinking and esterification of starch with the mixed anhydride of adipic acid and acetic anhydride and double denaturation of starch. The modified starch has excellent water breaking resistance, good transparency, low temperature stability and acid resistance.
