In Isfahan province of Iran, pistachio and almond are used specifically as ingredients to produce Gaz sweets, which are a typical product of Isfahan and exported to many countries. In this survey, 112 samples were gathered from different corresponding Gaz producers from 2007 to 2012 to evaluate the occurrence of aflatoxins (AF) in these products. Samples were analysed for AFB1, AFB2, AFG1 and AFG2 using immunoaffinity column clean-up (IC) and quantified by high-performance liquid chromatography (HPLC) with fluorescence detection. Among the samples analysed, AFB1 was detected in 13.4% of the samples above the maximum limit (ML) as set in Iran (5 µg/kg). Total AF (AFT) was above the ML in 9.8% of the samples. This study showed that full consideration is equally essential for nuts used as ingredients in special food products such as the Gaz sweets as for nuts for direct human consumption. It suggests a need for modifying the current trend of supervision.
在伊朗的伊斯法罕省，开心果和杏仁专门用作生产 Gaz 糖的原料，这是伊斯法罕的一种典型产品，并出口到许多国家。在这项调查中，从 2007 年到 2012 年，从不同的 Gaz 生产商收集了 112 个样本，以评估这些产品中黄曲霉毒素（AF）的发生情况。使用免疫亲和柱净化（IC）对样品进行 AFB1、AFB2、AFG1 和 AFG2 的分析，并通过高效液相色谱（HPLC）与荧光检测进行定量。在所分析的样品中，13.4%的样品中 AFB1 超过了伊朗设定的最大限量（ML）（5 µg/kg）。9.8%的样品中总 AF（AFT）超过了 ML。本研究表明，对于用作特殊食品（如 Gaz 糖）原料的坚果，以及直接供人类食用的坚果，同样需要充分考虑。这表明需要修改当前的监督趋势。
