A fast and simple anal. method was developed and characterized for the determination of aflatoxins (B1, B2, G1 and G2) in rice. The procedure is based on a simple solid-liquid extraction without further clean-up, and anal. by ultra-high performance liquid chromatog. coupled with fluorescence detection. Fluorescence emission of aflatoxins B1 and G1 was enhanced by post-column chem. derivatization using pyridinium bromide perbromide. The anal. method was satisfactorily characterized in white and brown rice. Under optimum conditions, external calibration in solvent could be used for quantification purposes and limits of quantification were below the maximum contents established by the European Union regulation for these contaminants/commodity group combination (0.07-0.14 μg/kg for white rice and 0.20-0.28 μg/kg for brown rice). Recovery studies carried out at three different concentration levels (0.5, 2 and 5 μg/kg) showed values in the range of 84.5-105.3%, and RSDs≤5%.
Food Chemistry published new progress about Extraction. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, SDS of cas: 112-63-0.
