玉米醇溶蛋白复合膜在草莓保鲜中的应用研究

Applied Research of Zein Composite Film in Strawberry Preservation

玉米醇溶蛋白有极强的疏水性和良好的成膜性,可用做果蔬等农产品的保鲜膜,绿色无毒。采用正交实验方法筛选最佳涂被剂配方的结果表明,玉米醇溶蛋白2.5%,甘油0.10%,柠檬酸0.15%,浸泡时间1 min保鲜效果最佳。

Zein has strong hydrophobic,good film-forming,green and non-toxic properties,and can be used as fresh- preservation films for fruits,vegetables and other agricultural products.The orthogonal experiment results showed the best conditions of the film solution:zein 2.5%,glycerin 0.10%,citric acid 0.15%and the soaking time 1 min.
