摘要
以菊粉作为羰基供体,与玉米醇溶蛋白的氨基进行糖基化反应,探讨改性成膜的最佳工艺,并对膜的各种性能进行了检测。结果表明:当物料比(蛋白/糖)101(g/g),反应溶液pH6,反应时间48h制得的玉米醇溶蛋白—菊粉共价交联膜达到最佳状态,该条件下膜的抗拉强度为10.12MPa,接枝度为37.5%。改性后的玉米醇溶蛋白膜的透光率、阻水、阻油、阻氧性均优于原玉米醇溶蛋白膜。
The modification conditions of the film were optimized using zein and inulin as raw materials, and the properties of them were measured. The results showed that the optimum conditions were material ratio 10 1 (g/g), pH 6 with reacting for 48 hours . Under these conditions, the tensile strength of the zein-inulin film was 10.12 MPa, with 37.5% of the graft. the light transmittance, water resistance, oil absorption, and oxygen barrier of inulin-modified zein films were better than those in the original ones.
