摘　　要：实验利用60%无水乙醇作为溶剂,用紫外分光光度计在273nm处测定白酒中的糠醛,该方法线性相关系数R^(2)值为0.99987,回收率为95.0%~97.8%,相对偏差(RSD)为0.18%。结果证明该方法可用于准确测定白酒中的糠醛含量。The furfural in baijiu was quantitatively analyzed by UV spectrophotometry at 273nm,with 60%anhydrous ethanol as solvent.The method showed that the linear correlation coefficient R^(2) was 0.99987,the recovery was 95.0%~97.8%,and the relative deviation(RSD)of the parallel sample detection results was 0.18%,which showed thatthe method could be accurately used to detect furfural in baijiu.
