摘要 大曲酒是以大曲作为糖化发酵剂,以高粱、小麦为主要原料,经蒸煮、糖化、发酵、蒸馏、贮存、勾兑而制成的蒸馏酒。大曲酒生产过程产生的副产物黄水中含有大量的乳酸。本研究采用大孔弱碱性阴离子交换树脂对黄水中的乳酸进行提取,得到了较好的提取效果。经实验分析,树脂对乳酸的动态吸附过程的最佳条件为:样品上柱流速为1.5 BV/h、洗脱液为5 %(v/v)的硫酸溶液、洗脱流速为3.5 BV/h,乳酸回收率可达75 %以上。

英文摘要 Daqu used as the saccharifying and fermenting agent, sorghum and wheat used as main raw materials, after cooking, saccharifying, fermentation, distillation, storage and blending, product Daqu Baijiu was finally produced. Yellow water, the by-product in the production of Daqu Baijiu, contained large amount of lactic acid. In this study, lactic acid was extracted from yellow water by macroporous weakly basic anion exchange resin, and the extraction effects were satisfactory. Through the analysis of the experimental data, the best extraction conditions were summed up as follows: the flowing rate of yellow water into the column was 1.5 BV/h, the eluent was 5 % (v/v) H2SO4, and the flowing rate of elution was 3.5 BV/h. As a result, the recovery rate of lactic acid could reach up to above 75 %.
英文关键词 Daqu Baijiu; yellow water; macroporous weakly basic anion exchange resin; lactic acid
