Analysis of Microbiological Contamination and Biogenic Amines Content in Traditional and Commercial Doenjang

Abstract

This study was carried out to analyse the microbio\logical contamination and biogenic amines(BA) content in Korea traditional soybean paste and commercial soybean paste. The results of microbio\logical analysis through Korean traditional soybean pastes() were , commercial soybean pastes() were for APC (Aerobic Plate Count), and , H5, H6 soybean pastes were 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(trypramine), 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.
