摘　　要：为了更快捷、更精确的测定大曲的糖化力,选用葡萄糖作为标准品,使用流动化学分析仪对已知样品进行了测定。在5.2mg/(mL.h)～31.2mg/(mL.h)浓度范围内,具有良好的线性关系(R=0.99997)和重现性(RSD范围为0.195%～0.328%),空白加标回收率较准确(99.68%～104.24%),并具有较低的检出限[4.996×10-2mg/(mL.h)]。因此该方法可作为一种快速、准确的检测方法应用于生产。To determine the saccharification ability of Daqu quickly and accurately, flow chemical analyzer was used for the detection of known samples with glucose as standard. The data showed good linear relation （R=0.99997） and repeatability （RSD range 0.195%-0.328%） when the saccharification ability ranged from 5.2mg/（mL · h） to 31.2mg/ （mL· h）. The recovery rate （99.68%-104.24%） of control was accurate. The detection limit [4.996×10^-2rng/（mL ·h）] was low. The method could be used in production for its rapid and accuracy.
