摘　　要：以玉米醇溶蛋白、纳他霉素、丁香酚、甘油、乙醇为原料,采用流延法制备成负载丁香酚/纳他霉素的玉米醇溶蛋白膜,通过单因素实验对成膜工艺进行优化。并将负载丁香酚/纳他霉素的玉米醇溶蛋白膜涂膜于柑橘表面进行保鲜。结果表明:当玉米醇溶蛋白和80%乙醇固液比1∶10(g/mL),纳他霉素含量0.05%,丁香酚含量10ug/0.05%纳他霉素,甘油浓度为玉米醇溶蛋白的20%时,膜的拉伸强度7.6MPa,红外光谱图和差热分析图表明添加物没有改变玉米醇溶蛋白的主要结构且具有良好的相容性。柑橘表面涂膜保鲜实验结果表明,负载丁香酚/纳他霉素的玉米醇溶蛋白膜涂膜处理保鲜显著。The geniamycin zein membrane was prepared by zein, mycin, eugenol, glycerol and ethanol, and the film forming process was optimized by single factor experiment. The film membrane was coated on citrus surface. The results showed that in the following conditions of ratio of zein to 80% ethanol 1 ＂ 10 （g/mL）, mycin 0.05%, eugenol 10ug/mL, glycerol 20% of zein, the tensile strength of the membrane was 7.6MPa. Infrared spectrum and the differential thermal analysis chart showed that the main structure of the corn gliadin was not changed, the compatibility was good. The results showed that corn zein film with eugenol / natamycin on citrus surface has significant fresh-keeping effects.
