2024年1月1日 · This study aimed to investigate the prevalence of aflatoxin B1 (AFB1) in four kinds of fermented soybean-related products used as traditional Chinese food: fermented soybean (FS), fermented qianzhang (FQ), fermented bean curd (FB) and fermented okara (FO).

Soybean trypsin inhibitors are thought to ward off pathogens. Studies with aflatoxigenic strains of Aspergillus flavus and A. parasiticus, frequent soybean contaminants, revealed that trypsin inhibitors do not affect the growth of these fungi and ...

The distribution of mycotoxins in soybean fractions, according to their commercial grading system, namely whole kernels (WK), split, broken and crushed kernels (SBCK), damaged kernels (DK), heat damaged and burned kernels (HDBK), moldy kernels (MK), greenish kernels (GK), foreign material + impurities (FMI), were analyzed using HPLC-FLD.

2015年12月15日 · The effects of chemical, physical, and cooking treatments on the reduction of aflatoxin B1 (AFB1), B2, G1, and G2 in soybean matrix were investigated. A HPLC-FLD with a Kobra cell system was used for the quantitative analysis of aflatoxins (AFs).

2021年12月1日 · Aflatoxins are group of naturally occurring mycotoxins that are mainly produced by fungus Aspergillus flavus and Aspergillus parasiticus. There are seven (7) major groups of mycotoxins reported,...

2018年9月1日 · Gamma irradiation could completely eliminate the fungi and greatly reduce the content of aflatoxin B 1 in soybeans with dose above 10 kGy. No significant change was found in the proximate composition of soybean and fatty acid composition of its oil even though the gamma irradiation dose was up to 30 kGy.

The concentration of total aflatoxin in individual soybean samples was tested by enzymelinked immunosorbent assay (ELISA) using a commercially-available kit. Other mycotoxins were analyzed using liquid chromatography-mass spectrometry (LCMS/MS) on 10 …

2016年10月3日 · Soybeans contain a small amount of zinc (0.01 μg/g) bound to phytic acid. Autoclaving soybeans at 15 pounds (6803.88 g) for 15 min increases the aflatoxin production, probably by making zinc available. Addition of zinc to both autoclaved and nonautoclaved soybeans promotes aflatoxin production.

2015年12月15日 · Cooking soybean milk (dehulling and boiling) reduced AFs effectively. The effects of chemical, physical, and cooking treatments on the reduction of aflatoxin B 1 (AFB 1), B 2, G 1, and G 2 in soybean matrix were investigated. A HPLC-FLD with a Kobra cell system was used for the quantitative analysis of aflatoxins (AFs).

Improper handling of soybeans (Glycine max L.) can lead to contamination by aflatoxins produced by Aspergillus flavus (A. flavus). This study investigated the ozonation technique in decontaminating aflatoxin, as well as the physical and microbiological quality of soybeans.
