摘要
分别用亚铁氰化钾滴定法、硫酸苯酚法、3,5-二硝基水杨酸比色法(DNS法)测定清爽型黄酒中的总糖,并对测定结果及精确度进行分析。结果表明,3种方法中3,5-二硝基水杨酸比色法与亚铁氰化钾滴定法的测定结果无显著差异,而且其精确度最高。
Total sugar in light yellow rice wine was determined by potassium ferricyanide titration, phenol-sulfuric acid method and 3,5-dinitros- alicylic acid colorimetry （DNS colorimetry） respectively and the determination results and the determination accuracy of the three methods were analyzed. The experimental results showed that there was no significant difference in the determination results between DNS colorimetry and potassium ferricyanide titration and the accuracy ofDNS colorimetry was the highest among the three methods.
