Effect of Ultrasonic Treatment on Acid Hydrolysis and Oxidation of Corn Starch

Abstract:

In this article, ultrasound was applied to the acid hydrolysis and oxidation of corn starch. The carboxyl content, viscosity of the starch prepared by the reaction under ultrasound and no ultrasound were studied through viscosimeter and titration method separately. The results showed that its carboxyl content of acid-thinned and oxidized corn starch with ultrasound was higher remarkably and increased by 14.81% at least, and its viscosity with ultrasound was evidently lower and decreased by not less than 37.78%, So ultrasound has a good performance in accelerating acid hydrolysis and oxidation of corn starch.
