Honey is a variegate matrix depending significantly on the floral origin, and it could become an important agri-food product to valorise specific territories. Being so diverse, different analytical techniques are necessary for its description. Herein we characterized the honey produced in one of the Italian sand dunes systems hosting beekeeping activities. In terms of floristic origin, phytochemical characterization, and sensory and colour analysis, honey collected in 2021 and 2022 was comparable. Honey was polyfloral, with several pollens from dune habitat plants classified as minor. The presence of the allochthonous Amorpha fruticosa L. and the ruderal Rubus fruticosus L. pollens in the category of the secondary pollens testifies the alteration of the park vegetation. The phytochemical profile was rich in polyphenols. Other interesting compounds were coumarine derivatives, likely attributable to resin-laden plants as rockroses, long chain hydroxyacids typical of royal jelly and nicotinic acid and its analogues (2-hydroxynicotinic acid and 2-hydroxyquinoline). The above-mentioned honey showed interesting features and was a good representation of the vegetation of this area. Our study pointed out the importance of relying on multiple analytical techniques for the characterization of honey and the advisability of a technical support toward beekeepers to correctly describe and valorise their product.
蜂蜜是一种杂色基质,其显著取决于花卉的起源,并且可以成为一个重要的农业食品产品,以提升特定地区的价值。由于其多样性,需要不同的分析技术来描述它。本文对意大利沙丘系统之一的养蜂活动中产生的蜂蜜进行了特征描述。在花卉起源、植物化学特性、感官和颜色分析方面,2021 年和 2022 年采集的蜂蜜具有可比性。蜂蜜是多花种的,有几种来自沙丘栖息地植物的花粉被归类为次要花粉。外来植物 Amorpha fruticosa L. 和杂草 Rubus fruticosus L. 的花粉出现在次要花粉测试中,证明了公园植被发生了变化。植物化学特征富含多酚。其他有趣的化合物是香豆素衍生物,可能归因于富含树脂的植物,如岩玫瑰,长链羟基酸是蜂王浆的典型成分,以及烟酸及其类似物(2-羟基烟酸和 2-羟基喹啉)。上述蜂蜜具有有趣的特性,是该地区植被的良好代表。我们的研究表明,依靠多种分析技术来描述蜂蜜的特性非常重要,并且建议向养蜂人提供技术支持,以正确描述和提升他们的产品。
