窖池中乳酸盐凝析现象研究

Research on the Lactate Condensate in Cellular

窖泥是浓香型白酒功能菌的载体,窖泥老化时,会出现白色团块物质和结晶体,主要成分为乳酸钙和乳酸铁。通过扫描电子显微镜-能谱仪分析、钙离子的含量测定、有机酸HPLC分析及酸强化试验证明了上面的结论;窖泥中盐分的成因有土壤、酒醅、水质、失水,控制措施:保证黄淤泥的质量、调整适宜的出入池参数、加大池口保养力度、适当增加窖帽。

The cellular mud is carrier of functional microbes of Luzhou style liquor. The white cluster and crystal which components are ealci um lactate and ferric lactate appear in the aged cellular mud. The above deduction is confirmed using scanning electron microscopy -energy spectrometer analysis, calcium content measurement, organic acid analysis by HPLC and acid intensifying test. The causes of the formation of the salt in the cellular mud are soil, water quality, water lost. The controlling methods include the quality assurance of the yellow mud, parame ter adjustment in and out cellular, the maintaining of the cellular entrance and proper covers.
