식용 가능한 펙틴/전분 블렌드 필름의 기계적 물성 및 가스 투과도 = Mechanical Properties and Gas Permeabilities of Pectin/Starch Edible Films

다국어 초록 (Multilingual Abstract)

Mechanical properties and gas permeabilities of edible films based on the blends of pectin with starch plasticized with glycerol were investigated. Tensile properties of pectin/starch blend films were changed significantly by the amount of glycerol and the ratio of pectin/starch. Tensile strength and modulus decreased as the content of glycerol increasing. With increasing glycerol content, elongation at break increased. Water absorption of pectin/starch blend films was changed by amount of glycerol but it was relatively little changed by the ratio of pectin/starch. Oxygen permeability of pectin/starch blend films was generally lower than of plastic films.
