海藻酸钠可食性膜对酱卤鸡腿的保鲜效果
Effect of sodium alginate-based edible coating on preservation of stewed chicken leg
-
摘要: 以抑菌率、失水率为评价指标,采用正交试验优化海藻酸钠可食性膜,并在15~20℃贮藏条件下对涂膜处理的酱卤鸡腿菌落总数、失水率进行了研究.结果表明,可食性膜最优配比为海藻酸钠20 g/L,氯化钙30 g/L,甘油30 g/L,涂膜处理对酱卤鸡腿的贮藏保鲜效果较好,能够降低失水率,延长货架期.Abstract: The sodium alginate-based coating was optimized by the orthogonal design method based on inhibition rate and moisture loss rate,and the changes of microbial count and moisture loss rate of stewed chicken leg dealt with sodium alginate-based coating during storage at 15~20℃ were investigated. The results showed the most optimal proportion of sodium alginate-based coating was sodium alginate 20 g/L,calcium chloride 30 g/L,glycerin 30 g/L.The sodium alginate-based coating had better preservation effect to stewed chicken leg.It could reduce moisture loss rate,prolong storage time and enhance hygiene quality of food.
