摘要
为了优化玉米醇溶蛋白的成膜工艺,采用L9〔34〕正交实验对玉米粉中醇溶蛋白的提取条件以及玉米醇溶蛋白成膜的最佳配方和成膜工艺进行了研究。结果表明,以80%的乙醇为溶剂,最佳提取条件为:料液比1∶13,pH7.0,50℃,1h;成膜的最佳配方为:醇溶蛋白总量与80%乙醇溶液之比为1∶10(g mL),油酸0.2mL,虫胶0.3g,成膜的温度宜>70℃。
In order to optimize the film making of zein handiwrap,the zein extraction and film making were studied with orthogonal tests.Results showed that the best conditions of extracting zein were 1∶13(the ratio of material and 80% ethanol),pH 7.0,50℃,1h.The best conditions of making zein film were the ratio of zein and 80% ethanol 1∶10,oleic acid 0.2mL,shellac 0.3g and>70℃.
