Reduction of aflatoxins by Korean soybean paste and its effect on cytotoxicity and reproductive toxicity--part 1. Inhibition of growth and aflatoxin production of Aspergillus parasiticus by Korean soybean paste (Doen-jang) and identification of the active component.

摘要: The inhibitory effect of methanol extract Korean soybean paste on the mold growth and aflatoxin production a toxigenic strain Aspergillus parasiticus ATCC 15517 was studied using different concentrations in yeast-extract sucrose broth. While inhibition due to increasing concentration observed, more remarkable production. Reduction mycelial weight as result addition observed range between 1.5 12.9% while reduction quantified by high-performance liquid chromatography ranged from 14.3 41.7%. Five percent significantly reduced at end incubation period (P < 0.05), although less pronounced. This study indicates that could also be an effective inhibitor even though may permitted. main active component identified gas chromatography-mass spectroscopy linoleic acid.
