Aflatoxin B1 in post-harvest peanuts and dietary risk in China

To monitor the aflatoxin contamination status in raw peanuts and evaluate the effect on public health; 1040 samples were collected from four agro-ecological zones throughout 12 provinces from 2009 to 2010 in China and then analyzed for aflatoxin B1 (AFB1) levels using High Pressure Liquid Chromatography (HPLC) and immunoaffinity columns. The results revealed that AFB1 […]

Aflatoxin B1 Degradation by Bacillus subtilis UTBSP1 isolated from pistachio nuts of Iran

Pistachio nuts are among the commodities with the highest risk of aflatoxin contamination in Iran. Aflatoxin B1 (AFB1) is one of the most hazardous mycotoxins for humans and livestock. In nature; there are microorganisms which are capable of reducing aflatoxins contamination in food and feed products. In this study; Bacillus subtilis strain UTBSP1 was isolated […]

Contamination of Cyclopiazonic Acid in Dried Figs and Co-occurrence of Aflatoxin

Natural cyclopiazonic acid (CPA) and aflatoxin (AF) contamination were investigated in Aspergillus section Flavi positive dried fig samples collected from orchards after harvesting. Cyclopiazonic acid and AF were determined by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC); respectively. Cyclopiazonic acid was found in all samples of dried figs that contain AF. Cyclopiazonic acid […]

Studies on contamination level of aflatoxins in some dried fruits and nuts of Pakistan

The occurrence of aflatoxins in dried fruits and nuts was surveyed in this study. One hundred and eighty samples of dried fruits and nuts were purchased from retail shops and local markets of different locations of NWFP and Northern areas of Pakistan. The samples were analyzed for total aflatoxins by immune affinity (IAC) clean-up with […]
