Honey is a common sweetener in the Jordanian diet with an annual consumption of approximately one thousand tons, two-thirds of which are imported. It is believed that the elemental profile of honey is an indicator of safety and botanical and geographic origin. In the literature, there are a lack of studies concerning the levels of major and trace elements in honey in Jordan. A total of 46 elements, including 15 rare earth elements (REEs), were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) in 18 monofloral and multifloral imported honey samples and 12 multifloral local samples. Regarding monofloral samples, Black Forest samples had the highest total metal content, while acacia samples had the lowest total metal content. Local multifloral honey had the largest Sr and total REE levels, while it had the lowest Mn levels. Very low levels of toxic elements were found in all samples, indicating the safety of honey in Jordan for human consumption. The results of this study showed that a large number of samples (> 100) and the application of advanced statistical models are required to discriminate between multifloral imported and local honey.

约旦蜂蜜中微量元素和稀土元素的含量

蜂蜜是约旦饮食中常见的甜味剂,年消费量约为一千吨,其中三分之二是进口的。人们认为,蜂蜜的元素特征是安全性以及植物和地理来源的指标。在文献中,缺乏关于约旦蜂蜜中主要元素和微量元素水平的研究。采用电感耦合等离子体质谱仪(ICP-MS)对18个单花和多花进口蜂蜜样品和12个本地多花蜂蜜样品进行了共46种元素的分析,其中稀土元素(REEs)15种。对于单花样品,黑森林样品的总金属含量最高,而金合欢样品的总金属含量最低。当地杂花蜂蜜的 Sr 和总 REE 含量最高,而 Mn 含量最低。在所有样本中都发现了极低水平的有毒元素,表明约旦的蜂蜜可供人类食用是安全的。这项研究的结果表明,需要大量样本(> 100)和先进的统计模型的应用来区分进口多花蜂蜜和本地蜂蜜。
