Study on Fresh-keeping Technology for Raw Milk

Abstract

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
