Caracterización de muestras demieles de azahar mediante desorcióntérmica –cromatografía de gases–espectrometría de gases

Abstract

The quality of honey and the ability to ensure it is an issue thatworries both producers and consumers. The palynological analysisis the most used method to determine the quality of honeyin terms of botanical origin. However, this method may havesome problems if applied to some types of honeys, such as citrus.The development of new analytical methods, such as the determinationof volatile organic compounds by gas chromatography,is an alternative to evaluate the quality of honey. It also canprovide a better understanding of the specific chemical compositionrelated to the botanical origin. Since there are compoundscalled “flower markers” characteristic of the honeys of each originand that can be used for their differentiation.In this work, a characterization of orange blossom honeys wascarried out by Thermal Desorption - Gas Chromatography -Mass Spectrometry (TD - GC – MS). The new analytical methodallowed for the selection of some chemical compounds to beused as specific chemical markers for the orange blossom honey.The dihydroxylinaool oxides and the lilac aldehyde isomerswere specifically selected.
