Modern Methods in the Analysis and Structural Elucidation of Mycotoxins presents available methods of analysis and structural elucidation of mycotoxins by recognized experts in the various disciplines. The approach in each chapter of the book is to present each method initially in theoretical terms and then to review the method as it specifically applies to the analysis and/or structural elucidation of mycotoxins. Comprised of 15 chapters, the book's opening chapters deal with screening, sampling, and survey methods for mycotoxins and toxigenic fungi. This is followed by chapters dealing mostly with methods for structural elucidation, such as NMR and X-ray crystallography and IR and UV spectroscopy, as well as biosynthetic techniques. Significant chapters consider the analytical methods for mycotoxin analyses, including enzyme-linked immunosorbent assay system and tandem mass spectrometry. The concluding chapter examines the mycotoxin analytical problem in taxonomic or ecological terms. This book is of value to food and feed researchers, scientists, and manufacturers who are interested in product contamination control.
