浅析白酒中铅含量超标原因及解决措施

Causes of Lead Content in Liquor Above Standards and the Solutions

白酒铅含量超标主要是由蒸馏器、冷凝器、导管和贮酒容器中的铅经溶蚀而带入,设备的铅含量越高,酒的酒度越高,则设备的铅溶蚀越大。改进蒸馏器、冷凝器、导管和贮酒容器等生产设备,采取低温入池发酵、定温蒸馏、保持适宜冷凝温度,定期刷洗蒸馏器、冷却器等方法可有效预防铅含量超标。白酒铅含量超标的解决方法有化学药物和生物技术法。(孙悟)

Lead content in liquor above standards was mainly induced by lead corrossion of distillator, condenser, piping line and liquor container. Higher lead content in those apparatus and higher liquor alcohol content would result in more serious lead corrossion. Accordingly, the improvement of those apparatus and the application of the techniques such as low temperature pit entry fermentation, fixed-temperature distillation, maintenance of adequate condensation temperature, and periodic washing of distillator and condenser etc. could effectively prevent lead content above standards. The solutions to lead content above standards in liquor included chemical drug method and biotechs. （Tran. by YUE Yang）
