| 摘 要： | 将原花青素(PC)添加到醋酸纤维素(CA)制膜溶液中,制得具有抗氧化性的可降解包装薄膜。通过红外光谱、X射线衍射和原子力显微镜对薄膜表面形貌、膜结构和结晶情况进行表征。以新鲜猪油为内装物、采用油脂氧化稳定性的检测方法Schaal烤箱法,测试薄膜在不同PC添加量时的抗氧化性。结果表明:当添加质量分数为2%PC时,薄膜的抗氧化性最佳,其对油脂的抑制率达到了37.65%,可在常温下延长油脂保质期两个多月。

| Abstract: | Cellulose acetate/procyanidins antioxidaitive packaging membranes are prepared by co-solution method.The structure properties of the membranes are characterized by FT-IR,XRD and AFM.In order to evaluate the antioxidation properties of membranes with different PC contents,the peroxide values(POV) of fresh lard packaged by membranes are measured in Schaal method.The results are that the membrane with 2% PC content has the most powerful antioxidation,its percentage inhibition of oxidation is 37.65%,and the she... |
