摘要
卵清蛋白和壳聚糖共混制备可食和可生物降解膜。以壳聚糖浓度、卵清蛋白浓度、甘油浓度、TG用量、催化反应温度等为实验因素,以抗拉强度和断裂伸长率为评价指标,研究了卵清蛋白-壳聚糖共混成膜的工艺。结果表明:5%卵清蛋白溶液和1%壳聚糖的混合溶液加入2%甘油,加入TG酶0.08%,于40℃保温30 min,冷却后铺膜,制得的膜机械性能好。
Egg albumin was mixed with chitosan to prepare a kind of edible and biodegradable film.Filming technology of ovalbumin-chitosan was studied by chitosan,egg albumin,glycerol,TG and reaction temperature as experimental factors and tensile strength and breaking elongation as evaluating indicators.Results suggested that compound solution of 5% ovalbumin and 1% chitosan was mixed with 2% glycerol,then added TG 0.08% and kept for 30 min at 40 ℃,prepared film after solution cooling,by which mechanical properties of the film were good.
