Honey has been used in the treatment of bacterial infections and inflammations since ancient times. However, the antibacterial effect and the active compounds and mechanisms of actions responsible for the antibacterial activity are less known in case of Hungarian unifloral honeys. The applicant’s task will be the wide-scale analysis of the antibacterial activity of Hungarian honey types, determining the antibacterial effect of honeys of diverse botanical origin with state-of-the-art microbiological methodology. Further aims of the research include detecting the active compounds (e.g. phenolic substances) in different honey types with suitable analytical techniques, and clarifying the mechanisms of action contributing to the antibacterial activity of honeys.
