摘　　要：采用回酒蒸馏技术,通过对浓香型大曲酒粮食、糟醅在发酵过程中取样,跟踪分析比较糟醅在发酵过程中常规理化指标的动态变化规律。结果表明,回酒蒸馏后糟醅淀粉利用率高,酒精发酵代谢活跃,生香发酵效果明显,原酒感官品质高。The technology of reflux liquor distillation was adopted in the experiments. The dynamic change rules of routine physiochemical index-es of fermented grains during the fermentation process were summed up through tracing analysis of fermented grains samples. The results showed that reflux liquor distillation could improve the utilization ratio of starch in fermented grains, stimulate alcoholic metabolism, enhance aroma-pro-ducing effects, and improve sensory quality of base liquor.
