[Methods of detecting and determining nitrogen-containing mycotoxins].

The influence of various nitrogen functional groups used for extraction cleanup and determination of N-containing mycotoxins (NM) in feeds and foodstuffs have been considered. TLC and LC are the most common techniques for detection and determination of nitrogen-containing mycotoxins. Gas chromatography has been used for determination (with or without derivatization) of several nitrogen-containing mycotoxins and/or their degradation products. Immunochemical techniques, in particular ELISA are available for only a very limited number of NM (e.g. ochratoxin A). Numerous methods for determination of ochratoxin A in feeds, grains, animal products and other foodstuffs have been developed. Methods for which recoveries have been carried out on spiked samples are also available for several other NM.
