Summary: A simple approach combining ultrahigh-performance liquid chromatography-quadrupole-Orbitrap high-resolution mass spectrometry with customized accurate-mass database and mass spectral library was developed for screening and identifying 63 mycotoxins in grain products. The proposed method showed a limit of detection of 0.001-20 µg/kg, recovery rates ranging from 61% to 109%, and a relative standard deviation below 9%. It was successfully used to investigate the presence of 63 mycotoxins in 398 samples, indicating its suitability for rapid screening and identification of mycotoxins in grain products.

Summary: In this study, cereal-based foods sold in temporary open-air markets were analyzed for the presence of various mycotoxins using LC-MS/MS. The results showed high levels of contamination, including aflatoxins, ochratoxin, zearalenone, deoxynivalenol, fumonisin, and T-2 toxins. The presence of multiple mycotoxins in grain-based foods poses a significant health risk that needs to be addressed through appropriate regulations and monitoring.

Summary: This review provides an overview of the latest developments in aflatoxins analysis in the past decade, with a focus on nuts and nuts-related products. Aflatoxins, produced by certain strains of Aspergillus fungi, pose a serious health threat and are considered carcinogenic to humans. The control of aflatoxins in food commodities is a significant challenge in terms of quality control and economic losses. This review discusses crucial steps in aflatoxins analysis, including sampling, sample preparation, separation, and detection, and highlights the challenges associated with these steps.
