Evaluation and prediction of the biogenic amines in Chinese traditional broad bean paste.

ABSTRACT: Biogenic amines (BAs) are a threat to the safety of broad bean paste, and biosynthetic mechanism of BA and its regulation are unknown. This study aimed to assess microbial BA synthesis in Chinese traditional broad bean paste and determine favorable fermentation conditions for BA regulation. The BAs content in 27 pastes was within the safe range. 64 strains with potential decarboxylation were screened in Luria-Bertani Glycerol medium and identified as Bacillus spp. Although Bacillus amyloliquefaciens produced highest levels of BAs (70.14 ± 2.69 mg/L) in LBAA, Bacillus subtilis produced 6% more BAs than B. amyloliquefaciens. Meanwhile, temperature was the most remarkable factor affecting BAs production by B. amyloliquefaciens 1-13. Furthermore, the fermente
