Mycotoxins are toxic secondary metabolites produced by fungi, which can exist in food as a result of fungal infection of crops. Their strong resistance to decomposition and digestion cause mycotoxins to remain in the food chain in meat and dairy products. The analysis of mycotoxins in food and animal feed has been a challenge mainly due to the complexity of food matrices and desired low detection limits. Immunoaffinity SPE cartridges have high selectivity for mycotoxins, but they are expensive and the procedure involves multiple steps during cleanup.  In this study, we investigate a line of new materials that are designed for sample preparation of mycotoxins in complex food matrices, such as grains and grain products. The materials are stable and rugged under common laboratory conditions. The proposed methods require only a single step cleanup. The performance and results achieved with these new methods will be discussed.
