À propos des douleurs des enfants et adolescents : questions posées au Docteur Valérie Guillouf

Abstract

Grape juice is a product widely sold throughout the world. In juice, the volatile components are extremely important as they characterize the aroma of the product, but these compounds are quite complex and present in small amounts in the juice. This study is to compare the identification of volatile compounds of two brands of grape juice by liquid–liquid extraction (LLE), using two different solvents (dichloromethane and hexane) and was identified through mass spectra obtained by gas chromatography-mass spectrometry (GC-MS) and linear retention index (LRI). The results show that LLE dichloromethane solvent extracted using a greater number of volatile compounds in both grape juice and the column chromatography to the more efficient identification of these compounds was the DBWax column.
