|
This study was carried out to analyse the microbiological contamination and biogenic amines(BA) content in Korea traditional soybean paste and commercial soybean paste. The results of microbiological anaylsis through Korean traditional soybean pastes(L1~L4) were 7.8 ± 0.1 log CFU/g ~ 7.9 ± 0.1 log CFU/g, commercial soybean pastes(H1~H6) were 6.2 ± 0.1 log CFU/g ~ 7.4 ± 0.1 log CFU/g for APC (Aerobic Plate Count), and L1~L4, H5, H6 soybean pastes were 2.3 ± 0.4 log CFU/g ~ 2.6 ± 0.1 log CFU/g for Bacillus cereus. But other microorganism was not dectected. Among biogenic amines, PUT(putrescine), TYR(tyramine), HIS(histamine), PHE(2-Phenylethylamine) were dectected high level and CAD(cadaverine), TRY(tryptamine), AGM(agmatine) were dectected medium level and SPD(spermidine), SPM(spermine), NOR(noradrenaline), SER(serotonin) were dectected low level. Dectected contents of biogenic amines were higher in commercial soybean paste compared to the traditional soybean paste.
