以竹叶提取物作为功能性添加剂,通过流延法制备了壳聚糖/竹叶提取物复合膜,研究了复合膜的力学性能、透光率、颜色、溶胀度、溶解性、氧气透过率和抗氧化等性能。结果表明:随着竹叶提取物含量的增加,复合膜颜色加深,透光率降低;拉伸强度增加,断裂伸长率降低;溶胀度与溶解度都降低,耐水性增强;自由基清除率升高,抗氧化性增强;复合膜阻氧性较好。 The bamboo leaves extract as a functional additive, prepared by casting chitosan / bamboo extract composite membrane, the mechanical properties of the composite film, transmittance, color, swelling, solubility, oxygen transmission Rate and anti-oxidation properties. The results showed that with the increase of bamboo extract content, the color of the composite film deepened, the light transmittance decreased, the tensile strength increased, the elongation at break decreased, the swelling degree and solubility decreased, the water resistance increased, the free radical scavenging rate High, anti-oxidation enhanced; oxygen barrier film better.
