- Abstract:
- Honey as a food product with plant origin that nearly ninety percent of its dry weight is composed of sugars (mostly fructose and glucose) which has many food and pharmaceutical properties. So honey quality strongly depends on bees feeding practices. For this reason common indexes is defined generally are on the basis of hony composition, for example fructose and reducing sugar portion must be at least thirty and sixty-five percent respectively of total weight or sucrose percent must be utmost five and otherwise puts into question honey quality. To check the quality of five honey samples taken from the market, indexes such as water content, sugar composition(fructose, reducing and total sugars), ash, HMF, acidity, pH and(diastase & invertase) units were measured. The only two samples for the sake of large amounts of sucrose identified low quality. In order to complete the investigation and to see the new indexes, biochemical method was used to mean that all honey samples are used as antibacterial material on the two bacterial species (S. aureus & E. coli) until antibacterial power of samples show their quality. Finally by common indexes only two samples identified poor while, by antibacterial index at least three of the samples due to high sugar syrup feeding showed low quality, and the other two also didn’t show suitable quality
