Focus on the release of the world's first high-throughput test standard for mycotoxins in feed

On the 11th, it was learned from the Chinese Academy of Agricultural Sciences that the latest agricultural industry standard "Liquid Chromatography Tandem Mass Spectrometry for the Determination of 37 Mycotoxins in Feed" was released and will be implemented

Su Xiaoou, chief of the team and researcher of the Institute of Quality Standards of the Chinese Academy of Agricultural Sciences, introduced that mycotoxin pollution in feed and agricultural products is a global problem, which brings serious challenges

The team focused on the practical problem of simultaneous pollution of a variety of mycotoxins in the feed, starting from the basic theory, which lasted 5 years of research, on the basis of a large number of experimental data, proposed the principle of impurity adsorption of multiple mechanisms, and developed an impurity adsorption purification column suitable for the simultaneous purification of 37 kinds of mycotoxins in the feed matrix, which solved the two key technical problems such as serious interference with the sample matrix, taking into account the huge differences in the structure and physical and chemical properties of different types of hazards, and the sample purification time was shortened from more than 40 minutes to less than

The study authorized 1 national invention patent and published 3 research papers in domestic and foreign journals; The formation of multiple mechanism impurity adsorption and purification technology has been transferred to relevant biotechnology enterprises, realizing the deep integration
