Abstract
- The occurrence of free and hidden fumonisins in raw maize and maize-based products from China was investigated. A total of 58 samples were analyzed using high-performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Among all the samples, 66% were contaminated with free fumonisins above limits of quantitation, and a higher percentage of 86% was found for total fumonisins (free + hidden). The highest contamination levels were observed in dried maize kernels which appeared mouldy, with mean levels of 15,737 and 30,785 µg/kg for free and total fumonisins, respectively. Frozen maize kernels, fresh maize kernels, and maize starch samples exhibited the lowest contamination levels, with no more than 200 µg/kg of total fumonisins. Except for one sample, the concentrations of total fumonisins were greater than those of free fumonisins with all the samples, the ratios of total-to-free fumonisins varied between 1.1 and 5.2, with an average ratio of 2.0.
