从伏伊伏丁那自治省（塞尔维亚共和国）采集了三种蜂蜜（两种单花蜜（洋槐蜜和向日葵蜜）和一种多花蜜（草地蜜））的45个蜂蜜样本，并对其理化参数（水分、酸度、pH值、灰分、电导率、葡萄糖、果糖、羟甲基糠醛（HMF）、CIE L*a*b*颜色和矿物质含量）进行了分析。除了水分（4个样本）和HMF含量（1个样本）外，所有测试的理化参数均符合欧盟法规。主成分分析（PCA）用于评估三种蜂蜜类型对所有所研究的理化参数的影响。根据PCA，洋槐蜜样本可以清晰地分离出来并形成一个聚类，而对于其他蜂蜜类型，PCA可以根据所检测的理化参数和矿物质含量提供区分向日葵蜜和草地蜜样本的可能性。
Forty-five honey samples of three honey types - two monofloral (acacia and sunflower) and one polyfloral (meadow) were collected from the Autonomous Province of Vojvodina (Republic of Serbia) and analysed for their physicochemical parameters (moisture, acidity, pH, ash, electrical conductivity, glucose, fructose, hydroxymethylfurfural (HMF), CIE L*a*b* colour and mineral content). All tested physicochemical parameters were in agreement with the EU regulation except for moisture (4 samples) and HMF content (1 sample).Principal component analysis (PCA) was used for assessing the effects of three honey types on all investigated physicochemical parameters. According to PCA, acacia honey samples can be clearly isolated and form a cluster, while, regarding other honey types, PCA can offer the possibility to distinguish sunflower and meadow honey samples regarding examined physicochemical parameters and mineral content.
