  • Title: Determination of aflatoxins in vegetable oils.

    Abstract:
    A simple method is proposed for determination of aflatoxins in vegetable oils. The method was successfully applied to both crude and degummed oils. The oil sample, dissolved in hexane, was applied to a silica column and washed with ether, toluene, and chloroform; aflatoxins were eluted from the column with chloroform-methanol (97 + 3). As quantitated by thin layer chromatography and liquid chromatography, the oils analyzed contained aflatoxin B1 at levels of 5-200 micrograms/kg. Recoveries of aflatoxin B1 standards added to aflatoxin-free oils were between 89.5 and 93.5%, with coefficients of variation of 6.3-8.0%.
