| Abstract: | This paper discusses a method for detecting benzoic acid sorbic and acid of cooked meat products with HPLC. We reform the way of pretreatments of our country's standard according to the samples containing high protein and high fat. As the result, we have achieved the goal of completely precipitating protein and easily filtering. The test result shows, the relative standard deviations of the method for benzoic and sorbic respectively are 3.0% and 3.9%, the adding recovery are 86.0%~87.5% and 85.0%~96.7% and the testing minimum quantities are 1.0ng and 0.5ng. |
