Abstract

Honey is appreciated, but still poorly investigated nutritional ingredient. The aim of this study was to contribute to the knowledge about honeys from Northwestern Croatia. The study was conducted on 25 samples of honeys and includes palynological and chemical analysis. Pollen analysis was performed by counting and determination of pollen extracted from honey samples. Chemical analysis included the spectrometric determination of 17 selected chemical elements in honey samples using ICP-AES (Inductively Coupled Plasma Atomic Emission Spectrometry) method. In addition, ATR (Attenuated Total Reflection) spectra were recorded to all samples. It turned out that only palynological analysis is insufficient to determine the botanical origin of honey, although it is good for determining the geographic origin. Elements content analysis proved to be more precise for classification of the honeys, but for the final confirmation of botanical origin it is still necessary to implement palynological analysis. ATR spectra can’t be used to classify honey samples just based on the assignment of prominent bands, ie without detailed assignment.
