The melissopalynological analysis of Rtanj honey revealed many types of pollen, of which the most important belong to the Rosaceae family, especially the Sorbus group. A relatively low value of the colour parameter L* (22.7 ± 0.19–59.8 ± 1.75), the positive a* value of 1.55 ± 0.07–22.3 ± 1.36, and a high content of K (996 ± 376 mg/kg) can be used as markers for its geographical origin authentication, which was confirmed using principal component analysis (PCA). The phenolic profile was evaluated based on the quantification of epicatechin (0.077 ± 0.005 mg/kg), p-coumaric acid (0.316 ± 0.004 mg/kg), ferulic acid (0.524 ± 0.002 mg/kg), naringenin (3.386 ± 0.011 mg/kg), luteolin (0.022 ± 0.006 mg/kg), kaempferol (0.628 ± 0.010 mg/kg), and apigenin (0.120 ± 0.002 mg/kg) using high performance liquid chromatography. The colour of Rtanj honey samples varied from extra white to light amber. | URI: | https://open.uns.ac.rs/handle/123456789/32751 | ISSN: | 0889-1575 | DOI: | 10.1016/j.jfca.2024.106088 |
