Health benefits of honey have been reported in a variety of conditions including microbial infections, wound healing, inflammation, glucose tolerance and analgesia. Honey is a supersaturated sugar solution mainly comprised of D-fructose, D-glucose, sucrose, maltose and higher sugars (-80% of solid mass). While other natural products i.e. alkaloids, flavonoids/ isoflavones, glycosides, phenolics, peptides/ proteins are present in minor quantities. A number of enzymes such as invertase, amylase and glucose oxidase have been found in honey. Antibacterial and antifungal activities of honey are well documented and characterized. These antimicrobial properties have been related to oligosaccharides, glycopeptides and peptides present in honey. Honey glucose oxidase provides a continuous and slow release of hydrogen peroxide at a level which is antibacterial but not tissue-damaging. Hydrogen peroxide produced by glucose oxidase plays important roles in inflammation, wound healing etc. The antimicrobial properties of honey have great potential for application in medicine as well as in food industry.
