Aflatoxin levels in hazelnut samples obtained from exporter companies were monitored over a 3-year period. A total of 3188 samples of raw and processed hazelnuts were analysed using an HPLC method. The total aflatoxin content of the contaminated samples was in the range of 0.02-78.98 µg kg(-1) for hazelnut kernels, 0.07-43.59 µg kg(-1) for roasted hazelnut kernels, 0.02-39.17 µg kg(-1) for roasted sliced hazelnut kernels, and 0.02-11.20 µg kg(-1) for hazelnut purees, respectively, showing that the variations of aflatoxin contamination were very high. The results of aflatoxin analysis revealed that the aflatoxin contamination in the hazelnut samples was at a tolerable level. A total of 3147 samples were contaminated with aflatoxins, although below the legal limits. However, the aflatoxin contents of 41 samples exceeded the legal limits. Therefore, aflatoxin contents of hazelnuts should be monitored regularly to minimise the risk of aflatoxin hazard, and pre- and post-harvest strategies should be developed to prevent aflatoxin formation.
在三年的时间里，监测了出口商公司获得的榛子样本中的黄曲霉毒素水平。使用 HPLC 方法分析了总共 3188 份生榛子和加工榛子样品。污染样品的总黄曲霉毒素含量范围为榛子仁 0.02-78.98µg/kg、烤榛子仁 0.07-43.59µg/kg、烤切片榛子仁 0.02-39.17µg/kg 和榛子酱 0.02-11.20µg/kg，表明黄曲霉毒素污染的变化非常高。黄曲霉毒素分析的结果表明，榛子样品中的黄曲霉毒素污染处于可接受的水平。尽管低于法定限量，但共有 3147 个样本受到黄曲霉毒素的污染。然而，41 个样本的黄曲霉毒素含量超过了法定限量。因此，应定期监测榛子中的黄曲霉毒素含量，以将黄曲霉毒素危害的风险降至最低，并应制定收获前后的策略以防止黄曲霉毒素的形成。
