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 examined the extraction of mycotoxins from walnuts using solid-liquid extraction (SLE) and explored various clean-up methods. The main limitation in analyzing mycotoxins in fatty matrices was the strong matrix effect encountered. However, dilution and injection proved to be effective in reducing the matrix effect, and a viable dilute-and-shoot method was proposed.

Summary: This study develops a simple, cost-effective, and reliable method for determining secondary volatile degradation products in drying oil extracts. The method involves the use of QuEChERS-based extraction, metal oxide-based dispersive solid-phase extraction (d-SPE) clean-up, and high-performance liquid chromatography with diode array detector (HPLC-DAD) analysis. After three months of storage, it was found that methanol was most likely oxidized to formaldehyde and formic acid, with the highest concentrations of formaldehyde and formic acid observed in linseed oil.

Summary: A robust and sensitive UHPLC-MS/MS method was developed for the simultaneous determination of 9 mycotoxins, AA, and 5-HMF. EMR-lipid d-SPE was used for clean-up of the extracts, and a new column phase (C18-PFP) was selected for HPLC separation. The method showed good linear relations and high recovery rates, making it a potential tool for cookies quality control.

Summary: The study evaluated the efficiency of different clean-up sorbents for analyzing dithiocarbamates in soybeans, finding that silica was an effective and inexpensive sorbent for removing matrix components without losing CS2. The method had a limit of quantification of 0.05 mg CS2 kg(-1) and both GC-ITD-MS and GC-PFPD systems were suitable for determining dithiocarbamate residues in soybean extracts.

Summary: Growing evidence of the importance of vitamin K in human health beyond blood coagulation and bone health necessitates further research. A method for extraction, lipase treatment, clean-up, and detection and quantification of various forms of vitamin K was developed and validated in a single laboratory. Deuterium labelled MK-7 can be used as an internal standard for MK-9, showing the potential for accurate quantification.

Summary: A robust and rapid HPLC method was developed for analyzing beta-carotene and beta-apo-8'-carotenal in processed foods. The method was validated for different fat content food matrices and identified the two carotenoids using LC-MS/MS. The method had low detection limits and met the accuracy and precision guidelines. It was applied to 57 processed food samples in Korea, revealing varying levels of beta-carotene and beta-apo-8'-carotenal, with chocolate and cheese having the highest levels. The method was also able to detect beta-carotene in samples without labeled carotenoid additives, and it was compatible with different processed food matrices.

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.
