摘要
本试验研究了玉米醇溶蛋白（Zein）溶液的浓度、pH值、干燥温度及增塑剂种类与数量等条件对Zein包衣抗张强度（TS）和透气性（Ap）的影响。结果发现，当Zein浓度为10%、pH=5、干燥温度为45℃、添加2%的甘油时所制得的包衣具有良好的外观、TS与Ap，其中TS达1.47kN/m，Ap为1.54μm/Pa·s。为Zein包衣的实际应用提供了基础依据。
Tensile strength (TS) and Air permeability (Ap) were investigated in the zein Coating prepared by different processing parameters,such as zein concentration,pH,dried temperature and amount of plasticizing agents added.The optimum results of the best zein coating appearanse TS and Ap were 10% zein,pH=5,drying temperature 45℃ and 2% glycerine.Ts was 1.47kN/m,Ap was 1.54μm/Pa.s.
