Abstract
The benzoic acid, sorbic acid and sodium saccharine in milk beverage were determined with high performance liquidchromatography.This method is simple in pre-treating samples, and is fast which is suitable to test the samples in batches. The recovery rates of benzoic acid ,sorbic acid and sodium saccharine were 97.8%,98.1% and 98.7% respectively, the variation coefficients of benzoic acid, sorbic acid and sodium sacchrine were 2.2%,1.9%and 1.4%respectively.
