Method Reference:
Ion Exchange Chromatography of amino acid profile based on AOAC Official Method 994.12. Internally developed method for sample hydrolysis and extraction.
Method Description:
The peptide linkages in the food sample’s proteins are broken by acid hydrolysis. After the acid is removed, the sample is diluted with a buffer solution and filtered. The sample is then injected on an HPLC. Repsonses are compared to a known calibration standard.
