Production and treatment process of purine-free fen-flavor liquor

The invention relates to the field of fen-flavor liquor, in particular to a production and treatment process of zero-purine fen-flavor liquor, which comprises the following steps: adsorbing and removing impurities and adsorbing purine substances by using activated carbon with the particle size of 200 meshes, the iodine value of 900mg/g and the pH value of 2.5; and filtering again by using an ultra-high molecular weight polyethylene microporous membrane in combination with diatomite. According to the method, the production of zero purine in the white spirit is realized by improving the process of the fen-flavor white spirit, and compared with the traditional process, the method not only realizes the zero purine level, but also keeps the taste and flavor of the white spirit, and meets the urgent demand of consumers on zero purine and healthy white spirit. 本发明涉及清香型白酒领域，特别涉及一种零嘌呤清香型白酒的生产处理工艺，采用粒度200目，碘值900mg/g，pH2.5的活性炭吸附除杂同时吸附嘌呤物质；使用超高分子量聚乙烯微孔膜结合硅藻土再次过滤。本发明通过针对清香型白酒的工艺改进，实现了白酒中零嘌呤的生产，相较于传统工艺，该方法不仅实现了零嘌呤水平，而且保持了白
