Title:
METHOD FOR PRODUCING HYDROXYCINNAMIC ACID
Document Type and Number:
WIPO Patent Application WO/2017/170549
Kind Code:
A1
Abstract:
The present invention relates to a method for efficiently producing high-quality hydroxycinnamic acids from a cellulose-containing biomass. More specifically, the present invention relates to a method for producing hydroxycinnamic acids, which comprises: a step for obtaining an alkaline filtrate by causing an alkaline aqueous medium to permeate through a cellulose-containing biomass; a step for obtaining an extract solution of hydroxycinnamic acids by repeatedly causing the alkaline filtrate to permeate through the cellulose-containing biomass; and a step for separating the hydroxycinnamic acids from the extract solution of the hydroxycinnamic acids.
