WebIn this research, oxidized sucrose, a novel aldehyde-based green cross-linker, endowed starch films with substantial improvement in both tensile strength and elongation, whereas many other cross-linkers did not. Starch films are usually weak, brittle, and highly moisture sensitive, and thus have restricted industrial applications. Cross-linking is one of the … Webcrystallinity, also influenced by processing parameters, is caused by the fast recrystallization of amylose into single-helical structures. Increasing the screw speed during extrusion or increasing residence time during kneading causes an increase in single helical type crystallinity.
