摘要(Abstract):

目的:建立紫外分光光度法测定6种市售酒中糠醛的含量。方法:利用紫外分光光度法对6种市售酒中的糠醛含量进行测定。结果:糠醛在10.01~50.05 mg/L浓度范围内线性良好,r=0.988 3,平均回收率为101.8%,RSD为2.89%(n=6),6种市售酒中糠醛的平均含量为24.09~49.75 mg/L。结论:紫外分光光度法简便准确,可靠,重现性好,专属性强,可用于市售酒中糠醛的含量测定。
Objective: To establish a method for content determination of furfural in wine with ultraviolet spectrophotometry.Methods: Ultraviolet spectrophotometry method was used to test furfural content in 6 kinds of wine.Results: Furfural content presented a good linear relationship in the range of 10.01~50.05 mg/L,r=0.988 3.The average recovery was 101.8%,RSD was 2.89%(n=6).The average contents of furfural in these six kinds of wine were 24.09~49.75 mg/L.Conclusions: The method is simple,reliable with good reproducibility and strong specificity for determining the content of furfural in wine.
