摘　　要：糖化力为大曲质量控制的主要指标,准确快速的测定糖化力对大曲生产质量的控制具有重要意义。该文用还原糖测定仪建立了大曲糖化力快速测定方法,并与常规手工滴定方法进行比较。测定结果显示,还原糖测定仪法变异系数较手工方法小,回收率也优于手工方法。此法可作为酒曲中糖化力快速测定方法。Saccharifying power is a key index to measure the Daqu quality. It is very important to analyze saccharifying power of Daqu quickly and rapidly in controlling Daqu quality. A new rapid method for detecting the saccharifying power was established by reducing sugar analyzer. The results showed that the variable coefficient and recovery of saccharifying power were better than manual titration method. It can be used for rapid determina- tion of saccharifying power.
