白酒混浊的原因分析及解决措施

Analysis of the Causations of Precipitate in Liquor and Relative Solutions

白酒产生混浊沉淀是一普遍问题 ,常见的有絮状沉淀 ,主要由3种高级脂肪酸乙酯引起 ,可于低温贮存过滤 ;白色片状沉淀 ,由贮酒容器引起 ,铝罐贮酒 ,会产生氧化铝溶入沉淀 ,最好不用铝罐贮酒 ;酒海贮酒会溶入涂料 ,造成沉淀 ,酒海贮酒不宜过久 ;由劣质添加剂引起 ,最好使用CP级或AR级添加剂 ;水质引起 ,对水处理应严加管理 ;包装材料引起 ,新瓶应用酸性水洗 ,且须控干水后再灌酒。(晓)

The precipitate in liquor is a common problem in distilleries which have to tackle with and the frequent causations are as follows: floccule induced by three kinds of higher fatty acid ethyl ester and microthermal storage and filtration could prevent it; white flakes of precipitate induced by containers for liquor storage such as aluminous pots which produced alumina and mare nectaris which dissolved into coating and then caused precipitate; precipitate induced by undergrade additives and CP grade or AR grade additives could prevent it; precipitate induced by water quality and strict management of water quality could prevent it; precipitate induced by packing materials and the solution was acid water washing for new bottles and liquor filling after the inner of the bottles was completely dry.(Tran.by YUE Yang)
