Investigation of various extractants of the analysis of aflatoxin B1 in different food and feed matrices
Various extractants were investigated concerning their suitability of aflatoxin B determination in spices, infant formula and animal feed employing an immunoaffinity clean up procedure. It was shown that the use of aqueous acetonitrile extractants was limited due to the fact that dry sample material can absorb significant amounts of water from the extractant. This can result in false recoveries and in incorrect values for the aflatoxin. Therefore it is recommended to use aqueous methanol extractants, since no significant interaction with matrix constituents was observed. In addition, aqueous acetone extractants are a useful alternative with some limitations.
