Volatile Fraction Composition of Acacia (Robinia Pseudoacacia) Honey from Romania, Spain and Check Republic

Abstract

The aim of this work was to evaluate the volatile fraction profile of acacia raw honey from different countries: Romanian, Spain, and Czech Republic. A melissopalynological analysis was conducted on all the batches in order to verify them as belonging to this type of honey. A number of 35 volatile compounds, more specifically: 2 acids, 10 alcohols, 7 aldehydes, 3 ketonas, 2 esters, 5 hydrocarbons, 4 terpenes, 1 furanes and 1 sulfur compound were identified by Purge and Trap-Thermal Desorption-GC/MS. The overall volatile profile of this honey allowed its classification by geographical origin. The promising results proved its usefulness for the differentiation of honey according to their origin. However further research on a higher number of samples is required in order to confirm this expectation.
