乳品中乳酸及乳酸盐的测定

The determination of lactic acid and its salts in dairy products

采用高效液相色谱法测定乳品中的乳酸及乳酸盐。应用有机酸专用色谱柱，折光检测器定量检测，本方法最低检测限为1.53×10^(－10)kg，变异系数CV(％)=1.72，回收率为97.5％～103．0％。

This is a method for determination of lactic acid and its salts in dairy products by HPLC.The ORH－801 column and refractometer were applied to determination.The minimum detectable values is 1.53×10^(-10)kg,variation coefficient CV(％) is 1.72,recovery is 97.5％～103．0％。
