摘　　要：以传统中高温大曲作为研究对象,重点探讨了曲药液化力在不同条件下的特征指标,再通过正交试验筛选出测定曲药液化力的最佳条件,并结合浓香型白酒生产工艺对试验条件进行修正,使所测液化力可最大限度反映实际生产中大曲参与的固态发酵效力,达到对曲药指标准确、快速测定的目的,并准确地结合曲药感官鉴定,判断出大曲液化能力优劣。Traditional high-temperature Daqu was the research object. The characteristic indexes of liquefying power of Daqu under different con- ditions were investigated and the best determination conditions of liquefying power of Daqu were screened out through orthogonal test. Besides, the experimental conditions were revised in consideration of the production techniques of Luzhou-flavor liquor. As a result, the measured liquefy- ing power could reflect the efficacy of solid fermentation involved by Daqu in practical production to the utmost extent. In combination with sen- sory judgment of Daqu, we could finally judge Daqu liquefying power accurately. （Tran. by YUE Yang）
