Hazelnuts of three different categories, mouldy, hidden mould and sound (undamaged), were investigated for their contents of aflatoxins (B1, B2, G1 and G2), patulin, and ergosterol. Samples were obtained from five hazelnut processing plants located in a major hazelnut producing area in the Black Sea region in Turkey. All aflatoxins, patulin and ergosterol were determined by high performance liquid chromatography (HPLC). Sound hazelnuts were contaminated with trace or zero amounts of aflatoxins, patulin and ergosterol, so they posed no risk for the consumer when national and/or international regulatory limits were considered. Mouldy and hidden mould hazelnuts were contaminated with high (246-510ppb; 141-422ppb) aflatoxin levels, respectively. Aflatoxin B1 content was significantly correlated with the patulin and ergosterol contents in mouldy and hidden mould hazelnuts. However, there was no significant correlation between patulin and ergosterol contents of mouldy and hidden mould hazelnuts.
研究了三种不同类别（霉变、隐蔽霉变和完好无损）的榛子，检测其黄曲霉毒素（B1、B2、G1 和 G2）、棒曲霉素和麦角固醇含量。这些样品是从土耳其黑海地区一个主要榛子产区的五个榛子加工厂获得的。所有的黄曲霉毒素、棒曲霉素和麦角固醇都通过高效液相色谱法（HPLC）进行了测定。完好无损的榛子中仅含有痕量或零量的黄曲霉毒素、棒曲霉素和麦角固醇，因此，当考虑国家和/或国际监管限制时，这些榛子不会对消费者构成风险。霉变和隐蔽霉变的榛子分别受到高浓度（246-510ppb；141-422ppb）的黄曲霉毒素污染。霉变和隐蔽霉变榛子中的黄曲霉毒素 B1 含量与棒曲霉素和麦角固醇含量呈显著正相关。然而，霉变和隐蔽霉变榛子中的棒曲霉素和麦角固醇含量之间没有显著相关性。
