Abstract
The Purpose of this study is to characterize the chemical and pollinical composition of French Guiana honeys to detect biological markers that can be used to justify origin of the product. For this, pollinical spectra have been established through determination and counting of pollen grains extracted from honey. Volatile fraction of each sample was characterized HS-SPME. Determination of phenolic compounds and the measurement of the antioxidant activity of the samples were also carried out.Study of pollen grains from honey, shows that there is an important pollinic diversity. This diversity is particularly explained by the significant presence of spontaneous species and a climate allowing multiple flowering. The main taxa of French Guiana repertoire as well as potential botanical markers of regional specificity were listed. This study provides French Guiana its first beekeeping pollen bank. An initial description of the botanical origin of Guianese honeys was formulated.Chemical study of the honeys’ fraction volatile shows that it is mainly dominated by compounds no terpenic oxygenated followed by monoterpènes oxygenated. A treatment statistical data permitted 87 honey samples to be allocated in 4 chemical groups. Finally, results from the dosage of phenolic compounds and antioxidant activity of honeys, reveal the presence of phenolic compounds. These data open the prospect of a study of these molecules of biological interest in French Guiana honeys.
