Abstract:
The amino acid analysis direct system was used to test the free-glycin in dairy drinks, and the methods for sample pretreatment and chromatographic parameters were studied in this paper. The test results were to analysis whether the dairy drinks had free-glycin added. The method is convenient, accurate and practical, the recovery rate was 98.8%~101.7%, RSD was 0.53%.
