Title
(EN) PROCESS FOR SELECTIVELY EXTRACTING PROCYANIDINS
(FR) PROCEDE D'EXTRACTION SELECTIVE DE PROCYANIDINES
Abstract
(EN)
A process is described for selectively extracting cocoa procyanidins from an aqueous mixture of cocoa polyphenols by using a particular sequence of solvents to extract selected procyanidin monomers and/or oligomers. The solvents are n-butyl acetate, ethyl acetate, methyl acetate, diethyl ether or mixtures of methyl acetate and diethyl ether. Preferably, the aqueous mixture of cocoa polyphenols is first extracted with n-butyl acetate. The mixtures of methyl acetate and diethyl ether are between 25:75 and 75:25 (v/v).

L'invention concerne un procédé qui permet d'extraire sélectivement des procyanidines de cacao d'un mélange aqueux de polyphénols de cacao en utilisant une séquence particulière de solvants pour extraire les monomères et/ou oligomères de procyanidine choisis. Les solvants sont l'acétate de n-butyle, l'acétate d'éthyle, l'acétate de méthyle, l'éther de diéthyle ou des mélanges d'acétate de méthyle et d'éther de diéthyle.
