A HPLC method for determination of sorbic acid,benzoic acid and sodium saccharin in dairy drink was studied.The comparison of five methods of precipitating protein showed that the solution of potassium ferrocyanide and zinc sulfate as protein's precipitant was appropriate.

探讨含乳饮料中山梨酸、苯甲酸、糖精钠的HPLC含量测定方法，在比较5种沉淀样品中蛋白质的方法后，确定以亚铁氰化钾与硫酸锌溶液为沉淀剂，采用C18反相柱，以甲醇：乙酸铵溶液(0.02 mol/L)=15∶85为流动相，紫外230 nm检测，结合保留时间及二极管阵列检测器光谱分析信息定性。

Methods: The protein and other impurity in the sample were precipitated by zinc acetate and potassium ferrocyanide after dipping of the sample. N,N-dichlorocyclohexylamine derived from sodium cyclamate by sodium hypochlorite in the filtrate was extracted by hexane. The HPLC separation was carried out with a phenomenex Gemini-C18 column using acetonitrile-water(7+3) or methanol-water (8+2) as mobile phase and detected by UV monitor at 314 nm. External standard method was used for quantification.

样品中甜蜜素浸提后，用乙酸锌和亚铁氰化钾试剂沉淀蛋白质等干扰杂质，过滤，用次氯酸钠将样品溶液中的甜蜜素转化为N，N-二氯环己胺经正己烷萃取后，在phenomenex Gemini-C18柱上，以乙腈－水(7+3)或甲醇－水(8+2)为流动相进行分离，HPLC-UV检测器在314 nm测定，外标法定量。
