摘要
通过对国标GB／T23495．2009食品中山梨酸钾含量方法的改进，建立一种简单稳定性好的方法，用于检测葡萄酒中山梨酸钾含量。结果表明，山梨酸浓度与液相色谱仪出峰峰面积呈线性回归，相关系数r为0．9998，回收率为91％～115．8％；检测葡萄酒样品时，RSD为2．08，稳定性和重复性好。
The study established a simple method of determination potassium sorbate in wine by modifying the GB/T 23495-2009. The results showed that the concentration of potassium sorbate and peak area were conforming to linear regression, and correlation index was 0.9998, the recoveries were 91% to 115.8%. The Relative standard deviation （RSD） was 2.08 when detect wine sample and the results were stable and repeatable.
