Determination of Amino Acids and Biogenic Amines in Soybean Paste by Pre-Column Derivatization High Performance Liquid Chromatography
Abstract: In this article, histidine, tyrosine, histamine, and tyramine in soybean paste were derivatized using OPA, followed by separation and determination using high-performance liquid chromatography. The results showed that the RSD of the method was 0.04%~1.16%, the recovery was 93.4%~101.2%, and the detection limit was 6~9 mg·kg-1. The method can meet the requirements of detection of histidine, tyrosine, histamine and tyramine during soybean paste fermentation.
