摘要
通过微生物鉴定和理化性质测定,对豆豉表面的颗粒状白色物进行分析。结果表明:豆豉返霜并非微生物污染所致,白色颗粒物大部分呈不规则块状结构,伴有少量杆状或针状,其溶解性差,主要成分为酪氨酸。500W功率微波处理120s,能有效抑制返霜现象的产生。
White granular substances on the surface of douchi were analyzed by means of microbiological identification and physio-chemical determination.Efflorescence on the surface of douchi was not caused by microbial contamination.Most white granular substances on the surface of douchi were massive in structure and small amounts of them had a rod-like or needle-like structure.They had poor solubility and the major composition was tyrosine.Efflorescence could be effectively inhibited by 500 W microwave treatment for 120 s.
