(2013): Mycotoxins and fungal metabolites in groundnut- and maize-based snacks from Nigeria

Abstract:
This exploratory study was aimed at investigating the spectrum of fungal metabolites in the processed food and snacks. Twenty types of snacks made separately from groundnut (n=10), maize (n=8) and a combination of groundnut and maize (n=2) were analysed for naturally occurring mycotoxins and other fungal metabolites by a liquid chromatography-tandem mass spectrometric multi-mycotoxin method. A total of 18, 21 and 32 metabolites were detected and quantified in the groundnut-, groundnut/maize- and maize-based snacks, respectively. Aflatoxins contaminated 2, 3 and 5 of the groundnut/maize-, groundnut- and maize-based snacks at concentrations up to 14, 1041 and 74 mu gkg(-1), respectively. Thus, the National Agency for Food and Drug Administration and Control (NAFDAC) recommended limit of 20 mu gkg(-1) for aflatoxins was exceeded in 6 of the 20 snacks. Fumonisins contaminated all the maize- and groundnut/maize-based snacks with higher concentrations in the maize-based snacks (mean=218.7 mu gkg(-1)) compared with the groundnut/maize-based snacks (mean=178.5 mu gkg(-1)). Up to 26 different metabolites were found to co-occur in the same samples, thus posing an additional threat to the consumers due to possible additive and/or synergistic effects.
