Summary: An economic and simple analytical method for detecting Zearalenone in maize oil was developed, showing good recovery rates and low relative standard deviations. Among refined maize oil samples from different brands collected in Tehran market, 55% were found to contain Zearalenone, but all results were below the maximum limits set by Iranian national standard and the EU.

Summary: This study detected ochratoxin A (OTA) in coffee using high-performance liquid chromatography with fluorescence detectors and calculated the OTA content, Margin of exposure (MOEs), and Hazard quotient (HQ) in different types of coffee. The results showed that the OTA concentration in classic and instant coffee was below the maximum limit defined by the European Union legislation. The daily intakes of OTA through classic and instant coffee were also lower than the proposed tolerance daily intake. However, consumers of instant coffee are at a cancer risk based on neoplastic effects.

Summary: The importance of food and beverage safety is crucial due to globalization and consumer demands. This review critically analyzes the presence of hazards and potential formation of toxic compounds in fruit-based fermented beverages. Techniques such as microbial fermentation and mycotoxin oxidation can help reduce or eliminate contaminants and ensure the safety of these beverages.

Summary: Global production of dried fruits has greatly increased in recent years due to the growing acceptance of packaged nutritious food and the use of dried fruits in confectionery and bakery goods. However, outbreaks and recalls caused by contamination and the presence of mycotoxins highlight the need for better approaches to ensure the safety of dried fruits. Drying processes alone are not sufficient to control these hazards, and pre-and post-drying treatments offer promising opportunities for efficient hazard control.

Summary: Mycotoxins are bioaccumulative contaminants that affect animals and humans. There is a need for dedicated, sensitive, reliable, and practical assays to detect and quantify the accumulated mycotoxin levels. In this study, we successfully developed and modified assays, such as high-performance liquid chromatography with fluorescence detection, enzyme-linked immunosorbent assay, and flow cytometry assays, to measure the accumulated mycotoxin levels in mice exposed to Ochratoxin A. The results showed positive correlations between the exposure doses and accumulated mycotoxin levels. Among the assays, high-performance liquid chromatography had the highest sensitivity. Blood samples contained higher levels of mycotoxins than liver and kidney samples.

Summary: This study aimed to simplify the conventional aflatoxin analysis method by utilizing the immunoaffinity column and normal-phase chromatography to detect aflatoxins B1, B2, G1, and G2. The optimized mobile phase enhanced fluorescence signal and improved sample cleanup method significantly increased recovery and repeatability. The proposed method outperformed the official method and met the US FDA's standards for examining human food, with a prolonged shelf-life of the mobile phase under room temperature.

Summary: Recent studies suggest that environmental toxins like mycotoxins may be risk factors for neurodegenerative diseases. However, the neurotoxic effects of mycotoxins such as ochratoxin A depend on their ability to penetrate or affect the integrity of the blood-brain barrier.

Summary: In this study, a modified HPLC analysis method was established for the detection of ochratoxin A (OTA) in licorice and its derivatives. The method achieved effective clean-up efficiency and selectivity without tedious procedures and specialized instrumentation. Analysis of licorice extract samples revealed a high contamination frequency and broad concentration range of OTA, indicating a potential acute risk. Improved supervision and regulation for OTA contamination in licorice samples are needed.

Summary: This study aimed to estimate the content of 13 mycotoxins in products from the eastern part of Poland. Mycotoxins were found in 27% of the 92 samples tested, with cereals showing the highest contamination rate at 56%. Deoxynivalenol was the most frequently identified mycotoxin, followed by zearalenone, toxin HT-2, ochratoxin A, and toxin T-2. Exceeding the maximum allowable concentration was observed in two samples.

Summary: A novel stationary phase for affinity separations based on sintered borosilicate glass is presented, showing fast binding kinetics and long-term stability. The material can be easily modified for selective binding, and columns and holders can be manufactured by 3D printing. High separation speed and pressure resistance allow for high productivity and purity of IgG purification with standard HPLC systems.
