摘要: 本实验研究了用乳酸链球菌素、甘氨酸、溶菌酶、抗坏血酸四种复合保鲜剂对原料乳进行保鲜。结果表明,在鲜乳中添加300mg/kg乳酸链球菌素、1g/kg甘氨酸、900U/ml溶菌酶、150mg/kg抗坏血酸后,于4℃条件下贮藏,贮藏期可达9d,贮藏期比单一的保鲜剂延长一倍以上,而且各项指标都符合原料乳的国家标准。

Abstract: Fresh-keeping effects of four kinds of composite preservatives such as nisin,glycine,lysozyme and ascorbic acid on raw milk were studied. Results showed that the storage period of raw milk reaches 9 d at 4 ℃,which is added with nisin 300 mg/kg,Glycin 1g/kg,lysozyme 900 U/ml and ascorbic acid 150 mg/kg. The storage period is more than two times of that of raw milk added with single preservative,and the related indexes accord with national standard.

Key words: fresh-keeping of raw milk, nisin, glycin, lysozyme, ascorbic acid
