Abstract

In this study, oxidized starch was taken as raw material to prepare filming. Single factor and orthogonal experiments were conducted to investigate its properties. The results showed that the different concentrations of oxidized starch, glycerol, polyvinyl alcohol (PVA) and glutaraldehyde had significant effects on the properties of the oxidized starch/PVA films, among which the most important factor was glycerol, followed by the oxidized starch, PVA and glutaraldehyde. The optimum film-forming conditions were 6.0% oxidized starch, 6.0% PVA, 2.5% glycerol and 0.6% glutaraldehyde.
