Description

Contamination by aflatoxins B1 and B2 in shelled peanuts harvested from Shizuoka Prefecture, Japan, was investigated. The extraction with methano1-1% NaCl solution (55:45, v/v), followed by purification on a Sep-Pak silica cartridge column, and HPLC analysis revealed the contamination of 5.9mg/kg of aflatoxin B1 and 0.3mg/kg of aflatoxin B2 in the shelled peanuts. Aflatoxin B1 was confirmed by mass spectral analysis. Mycological survey detected aflatoxigenic strains of Aspergillus flavus on peanut kernels in the infested lot.
