摘要
Abstract
Edible packaging material is a special packaging materials due to its edible property. It is the most widely used and studied. Sweet potato starch films is a very typical film. Effectof different content of konjac glucomannan on sweet potato starch film performance, such as tensile strength, water vapor permeability, oxygen permeability and color differences were researched. Results showed that tensile strain at break ( % ) increased with konjac glucomannan concentration (g/100g starch) (3%～7%) and this improved the film flexibility. Both tensile stress (MPa) and tensile strain at break ( % ) were better at 4% starch content. In addition, konjac glucomannan decreased water vapor and oxygen permeability of sweet potato starch film, but had little effect on the membrane color.关键词
