成品白酒中白色针状沉淀物的剖析

Analysis on the white needle-like sediment in the liquor

通过对成品酒中白色针状沉淀物的测定、试验和去除沉淀前后酒样分析,确定白色沉淀物为硫酸钙,产生原因主要因为加浆未软化处理和储藏温度较低。依据白酒国家标准要求,该种沉淀造成酒样感官和固形物超标,对其他理化指标没有影响。

By determination, experiments, and qualitatively analyzed produced precipitation＇s samples and sediment in liquor,experiments results showed that the main ingredient of sediments was calcium sulfate. The reason for the precipitation was the unsoften process and low temperature in storage. This condiment, which made sensory quality and solids in liquor over and above the national liquor standard, had no influence on other physical and chemical index.
