摘要
本文以豌豆淀粉/ε-聚赖氨酸为主要基材,以甘油、海藻酸钠等为增塑剂制备复合膜包装材料。采用单因素、正交实验等方法,在设定的工艺条件下流延成膜,进行复合膜的配方研究和最佳条件下膜性能研究。结果表明:最佳配方为100 m L水中加入10.5 g豌豆淀粉、1.5 g聚赖氨酸(调p H9)、1.80%甘油、0.50%海藻酸钠;产品性能检测表明,抗拉强度约为18.35 MPa,断裂延伸率约为34.79%,水蒸气透过率为12.10 g/(m^2·h),透油率为0.682 g·m/(m^2·h),对大肠杆菌具有较好的抑制性。本研究表明豌豆淀粉/ε-聚赖氨酸复合膜具有功能性包装应用的基础。
Pea starch/ε-Poly Lysine composite films were prepared by adding pea starch, with ε-Poly Lysine as matrix, glycerol and sodium alginate as plasticizer.Using single factor and orthogonal experiment, the formulation of the composite films was studied under the set process conditions.The films under the optimum conditions were characterized.The results showed that the best formulation was to add 12 g principal component（ pea starch/ε-poly lysine 7：1 ） , glycerol 1.80% , sodium alginate 0.50% in 100 mL aqueous solution. The product performance test showed that the tensile strength was about 18.35 MPa, the elongation was about 34.79%, the water vapor transmission rate was 12.10 g/（ m2 · h）, and the oil penetration rate was 0.682 g·m/（ m2·h） ,which had a good inhibitory effect on E.coli.This study showed that the pea starch/e-poly lysine composite film has the basis of functional packaging.
