Abstract: In this paper, protein and fat in the milk were mostly eliminated by the precipitators. Benzoic acid, sorbic acid and saccharin sodium were determined in the same time by HPLC with UV detector. The results were that the recovery was 93.1%~103.0%, the relative standard deviations are 0.78%, 1.15% and 1.51% respectively. The conclusion can be reached that the method is feasible, rapid and reliable.

Key words: benzoic acid, sorbic acid, saccharin sodium, HPLC, milk and dairy produce
