Optimization of Processing Technology of Acetylated Corn Starch Films

Abstract:

Abstract. In this experiment acetylated corn starch was taken as the raw material and its filming property was studied through single-factor experiments and orthogonal experiment. The results showed that the different concentrations of acetylated corn starch, glycerol, polyvinyl alcohol (PVA) and glutaraldehyde had significant effects on the properties of the acetylated corn starch/PVA films. And the optimum film-forming conditions were 4.5% acetylated corn starch, 4.5% PVA, 4.0% glycerol and 0.4% glutaraldehyde for the coating liquid of film-forming, among which the most important factor was the glycerol concentration; the following factors were the acetylated corn starch concentration, the polyvinyl alcohol concentration and the glutaraldehyde concentration.
