Abstract

 

Honey is a sweet flavourful product which has been consumed as a high nutritive value food. The present study aimed to characterize 12 samples of honeys collected from the North of Tunisia in respect to their floral origins. pH, hydroxyl methyl furfural, moisture content, ash, acidity, electrical conductivity, reducing sugars, apparent sucrose and total phenolic contents, were the parameters analysed in each sampleAll honey samples analyzed were found to meet European Legislation Ec Directive (2001/110) for all parameters studied. Antimicrobial assays showed that most honey samples tested inhibited the proliferation of Escherichia coli and Salmonella typhimuriumand altered theflagella driven motility of these two bacteria tested in swarming assay. We have also demonstrated that the most important antibacterial activity was observed for the honey originated from eucalyptus flower.
