为完善大曲质量评价体系与全机械化制曲工艺,对单层、双层大曲的理化指标、生化指标及微生物量进行测定,分析2种大曲的质量差异及大曲各指标间的相互关系,通过建立评价体系对单层、双层大曲质量进行直观分析。结果表明,单层、双层大曲的理化性能差异较小,单层大曲的发酵力、液化力、糖化力、酯化力、蛋白酶活力均高于双层大曲,贮存期单层大曲的微生物量高于双层大曲。单层大曲质量明显优于双层大曲,样品综合得分最高为S2M(0.89分),得分最低为D2M(0.21分),排名为S2M＞S1M＞D1M＞D2M。
In order to improve the quality evaluation system of Daqu and mechanical starter-making, the physicochemical, biochemical and microbial biomass of single-layer and double-layer Daqu were measured. The quality differences between two kinds of Daqus and the interrelationships between the Daqu′s indicators were analyzed. An evaluation system was established to directly analyze the quality of single-layer and double-layer Daqu. The results showed that the physicochemical properties of single-layer and double-layer Daqu were similar, but the fermentation force, liquefaction force, saccharification power, esterification power and protease activity of single-layer Daqu were higher than that of double-layer Daqu. The microbial biomass of single-layer Daqu was also higher than that of double-layer Daqu. The quality of single-layer Daqu was significantly better than that of double-layer Daqu. The products had the highest overall score of S2M (0.89 points) and the lowest score of the D2M (0.21 points) and the score size was S2M>S1M>D1M>D2M.
