Properties of Enzymatic Hydrolysis Corn Starch Sizing Agent Modified in Supercritical Carbon Dioxide

Abstract:

This paper describes an experiment of Corn starch treatment with α-amylase under the condition of supercritical CO2 at 50°C, 11MPa, and investigates the effects of different water content on supercritical CO2 treatment of corn starch. The results demonstrate that the viscosity of the treated starch is much lower than that of untreated starch, as well as the variance ratio of the viscosity is up to 96%. The optimum water content for the degradation of the enzymatic reaction is 2%;when water content is up to 3%, the viscosity of the serosity is 5Mpa•s, and the sizing performance reaches the best.
