摘要
分析廉价成膜材料大豆分离蛋白-阿魏酸与天然抗菌抗氧化物质茶多酚联合对冷鲜猪肉进行涂膜保鲜的可行性。本实验通过将茶多酚与廉价成膜剂混和后,测定保鲜过程中的冷鲜猪肉的pH值、颜色、烹饪损失、嫩度、脂肪氧化度TBA值、肉品中过氧化物酶活性,以及保鲜过程中细菌总数各项指标的变化,对冷鲜猪肉保鲜作用进行研究。结果表明,廉价成膜剂和茶多酚联合涂膜保鲜具有可行性,大豆分离蛋白-阿魏酸膜中添加茶多酚量为0.2%保鲜效果最佳。
In order to explore the feasibility of using cheaper preservative coating mixed with natural antibacterial or antioxidant materials for fresh-keeping of chilled pork, a cheaper preservative coating with tea polyphenols were prepared to use for the fresh-keeping of chilled pork. pH, color, cooking loss, tenderness, thiobarbituric acid （TBA） value for fat oxidation degree, peroxidase activity and total bacterial counts in treated chilled pork were determined. Results indicated that tea polyphenols could improve the fresh-keeping function of the cheaper preservative coating. Meanwhile, 0.2% tea polyphenols in the coating of soybean protein isolate and ferulic acid exhibited the best fresh-keeping effect on chilled pork.
