**3. Results and Discussion**

The findings of Serbian sunflower honey's physicochemical analysis obtained immediately after sampling are shown in Tables 1 and 2.

The results of the initial test indicated that Serbian sunflower honey is known for its good quality since the criteria that were closely correlated with the honey's quality were measured, and their levels complied with the limits established by international and national regulation. Analyses of water content, pH, free acidity, HMF, and diastase activity were performed to determine the effects of 18 months of room-temperature storage on the quality of honey. The findings of the selected physicochemical examination of Serbian sunflower honey, obtained after storage for 18 months, are shown in Table 3. The influence of the duration of storage on selected honey parameters is shown in Figures 1–5.
