要:文中研究了10x10"裁留分子量和20x10*截留分子量超滤膜处理生替油原液前后理化和微生物指标的变化,结果表明:利用 10x10*截留分子量或20x10*截留分子量超滤膜处理生酱油,总酸、氮基酸态鼠、全鼠、可游性固形物、食盐、无盐固形物等指标的保留率都在95%以上,而菌落总数和浊度指标下降非常显著,经10x10*截留分子量超滤膜处理,除菌率达99.9992%,浊度去除率达 98.84%:经20x10*截留分子量超滤膜处理,除荫率达99.9975%,浊度去除率达98.78%;经10x10*截留分子量超滤膜处理色度下降率达 44.7%;经20x10*截留分子量超滤膜处理色度下降率为16.3%。经过300d的室温储减,处理液未见明显浑浊,因此将膜处理技术应用于

Abstract: Changes of physiochemical and microbial properties of raw soy sauce before and afer respective treatment with membrane with molecular cut off by 10x10° or 20x10* molecular weight were studied. The results showed: more than 95% of total acid, salt, soluble solids, amino nitrogen, salt-free solids were kept and total number of colonies and turbidity of soy sauce decreased significantly when treatment with both membranes of 10x10 or 20x10* molecular cut off membrane. When filtrated with 10x10* molecular cut off membrane, 99.9992% of total bacteria were removed, the turbidity of soy sauce decreased by 98.84%, and the color degree decreased by 44.7%. When filtrated with 20x10* molecular cut off membrane, the three parameters were 99.9975%, 98.78%, and 16.3%, respectively. No significant feculence in filtrated products after storage of 300d under ro0m
