摘　　要：目的:建立一种方便、快速检测酱油中葡萄糖的方法。方法:用便携式血糖仪检测市售酱油中的葡萄糖,并进行重复性试验、回收试验、线性试验。结果:5种不同品牌酱油的葡萄糖浓度分别是25.38、8.28、31.86、8.82、12.06g/L,标准差SD为0.129,批内CV为2.9%,回收率99.9%～101%,平均回收率100.4%,线性方程为y=4.2608x+2.5929,相关系数R2=0.9991,在0.5～5g/L范围内线性关系良好。结论:便携式血糖仪能检测酱油中葡萄糖含量,为检测酱油中的葡萄糖提供了一种便捷的方法。Objective： Establish a convenient, rapid method for detection of glucose in the soy sauce. Methods： Detect the glucose in soy sauce by portable blood glucose meter and do the repeatability test, recovery test, linear test. Results： Glucose concentration of five different brands of soy sauce are 25.38, 8.28, 31.86, 8.82, 12.06 g/L. The SD=0.129, CV=2.9%, average recovery rate is 100.4%, the pertinence is y=4.2608x＋2.5929, R2=0.9991. The linearity studies shows that the method＇s linear range is 0.5-5 g/ L. Conclusion： Portable blood glucose meter can detect the glucose content in the soy sauce, could be a convenient method for the detection of glucose in soy sauce.
