Manuka honey plays a significant role in modern medical applications as an antibacterial, antiviral, and antibiotic agent. However, although the importance of manuka honey is well documented in the literature, information regarding its physicochemical characteristics remains limited. Moreover, so far, only a few papers address this issue in conjunction with the examination of the pollen composition of manuka honey samples. Therefore, in this study, two parameters crucial for honey quality control-the diastase number (DN) and the hydroxymethylfurfural (HMF) content-as well as the melissopalynological analysis of manuka honey, were examined. The research found a large variation in the percentage of pollen in honeys labeled and sold as manuka honeys. Furthermore, a significant proportion of these honeys was characterized by a low DN. However, since low diastase activity was not associated with low HMF content, manuka honey should not be considered as a honey with naturally low enzymatic activity. Overall, the DN and HMF content results indicate that the quality of commercially available manuka honey is questionable.
麦卢卡蜂蜜作为一种抗菌、抗病毒和抗生素药物，在现代医学应用中发挥着重要作用。然而，尽管麦卢卡蜂蜜的重要性在文献中已有充分记载，但关于其物理化学特性的信息仍然有限。此外，到目前为止，只有少数论文在研究麦卢卡蜂蜜样本的花粉成分时涉及到这个问题。因此，在本研究中，对蜂蜜质量控制至关重要的两个参数——淀粉酶值（DN）和羟甲基糠醛（HMF）含量——以及麦卢卡蜂蜜的花粉分析进行了研究。研究发现，标为麦卢卡蜂蜜并出售的蜂蜜中花粉百分比差异很大。此外，这些蜂蜜中有很大一部分的特点是淀粉酶值较低。然而，由于低淀粉酶活性与低HMF含量无关，因此麦卢卡蜂蜜不应被视为天然酶活性低的蜂蜜。总体而言，淀粉酶值和HMF含量结果表明，市售麦卢卡蜂蜜的质量令人质疑。
