Title:
SEMI-INTEGRATED METHOD FOR ENZYME-ASSISTED EXTRACTION AND PURIFICATION OF P-HYDROXYCINNAMIC ACIDS
Document Type and Number:
WIPO Patent Application WO/2023/135259
Kind Code:
A1
Abstract:
The invention relates to the field of the production of p-hydroxycinnamic acids. More particularly, the invention relates to a semi-integrated method comprising a first step of enzymatic hydrolysis and a second step of purification of the p-hydroxycinnamic acids, thus released, by liquid/liquid extraction using a membrane contactor. This method enables the purification of p-hydroxycinnamic acids from a plant biomass and the recovery thereof in the organic phase. It is conceivable to recover the p-hydroxycinnamic acids in the aqueous phase after a back-extraction step.
