摘要
对魔芋葡甘聚糖及其与大豆分离蛋白、分子蒸馏单甘酯、硬脂酸复配成膜的工艺条件和对迷你黄瓜的保鲜性能进行了研究.实验确定的最佳配比及工艺条件为w(魔芋葡甘聚糖)=2 0%,w(单甘酯)=0 5%,w(硬脂酸)=0 5%,m(魔芋葡甘聚糖)∶m(大豆蛋白粉)=1∶1,pH=9,溶胀温度为35℃.该复配膜对减少迷你黄瓜的失重率、抑制呼吸强度效果理想.
The film-forming characters of the mixture of konjac glucomannan (KGM), glycerol monostearate (GMS) ,stearic acid (SA) and soy protein isolated (SPI) were studied.The optimum conditions are w(KGM) =2.0%, w(GMS) = 0.5%, w(SA) = 0.5%, m(KGM): m(SPI) = 1: 1,pH = 9,swelling temperature is 35℃.The results showed that the edible compound film effectively inhibited the weight loss and respiratory quotient of the coating mini-cucumber.
