The study researchs on the hydrolysis process of food and feed samples using High PressureAsher (HPA-S) to determine several amino acids by high-performance liquidchromatography (HPLC). HPA-S equipment is mainly used for samples treatment in analysis ofmetals by spectroscopy. However, the study also found that HPA-S can be used in hydrolysis of foodand feed samples in order to analyze amino acids. The temperature of HPA-S equipment could reach300oC and maintain continuously at 130 bar pressure, completely digetsing the most complexsamples matrix within an hour. The successful study of the application of HPA-S to hydrolyzesamples in order to analyze amino acids makes the time of sample preparation significantly shorterbut still gave the equivalent stability, even higher than the common samples hydrolyzation. |
