Gas Transmission and Water Vapor Transmission Properties of High-Amylose Corn Starch/Chitosan Edible Film
摘要
Abstract
In this experiment, edible films from high-amylose com starch (HACS) and chitosan (CS) were developed by casting film-solution on leveled trays. The effects of ratio of starch to chitosan, glycerol dosage and methylcellulose (MC) dosage on CO2 and O2 transmission, water vapor transmission (WVT) of edible films were investigated. The result showed that the edible composite fihns had the lowest CO2 and O2 transmission and lower WVT when the ratio of chitosan and content of glycerol reach 2:1. The value of CO2 and O2 transmission increase to the highest and then decrease, and WVT increased while the ratio of chitosan and content of glycerol continued decrease. The increase of content of glycerol improved the CO2, O2 transmission and WVT of edible films first, and then decreased gradually. The addition of 2% methylcellulose decreased the gas permeability properties of the edible film to the lowest When the content of methylcellulose was between 4% and 6%, WVT of the edible film reached the lowest.关键词
