摘  要:
以大豆分离蛋白(SPI)和甘蔗木聚糖(Xylan)为成膜材料,研究成膜材料配比、增塑剂种类和浓度、溶液pH以及干燥温度等因素对膜的抗张强度(TS)、抗氧化性(POP)、水溶性、透光率、伸长率(E)以及水蒸气转移速率(WVTR)等特性的影响,以确定可食性复合膜的最佳制备工艺。结果表明:大豆分离蛋白∶木聚糖=8∶2、5%甘油、pH9.0、干燥温度60℃是制膜的最优条件。

摘  要:
Soy protein isolated( SPI) and sugar cane xylan( Xylan) were made to form edible packaging film. The effects of proportion of soy protein and xylan,the sort and concentration of plasticizer,the pH of solution and the drying temperature of membrane on tensile strength( TS),prevent oxygen permeability( POP),water soluble rate,light transmittance,elongation( E) and water vapour transfer rate( WVTR) of the film were studied to determine the best technology of edible composite films. Experimental results showed soybean protein∶ xylan = 8∶ 2,5% glycerol,pH9. 0 and drying temperature 60℃ were the optimal condition for preparation of membrane.
