EXTRACTION OF NATURAL FERULATE AND COUMARATE FROM BIOMASS
20220033341 · 2022-02-03 ·

A process for a reactive separation of organic molecules from biomass includes a reaction step for the biomass, a simultaneous extraction step using a solvent, and a filtration step to recover products, wherein the products comprise ferulic acid and/or coumaric acid. The products are extracted from the biomass in a pressurized stirred batch reactor using a liquid extraction solvent and a base in which the ferulate and the coumarate remain.

Method for extracting ferulic acid and/or its salts

Method for extracting ferulic acid and/or its salts from a previously conditioned source rich in ferulic acid and its salts which comprises adsorbing the ferulic acid and/or its salts on a column packed with synthetic resin, desorbing the ferulic acid and/or its salts using an organic solvent, separating the liquor rich in ferulic acid into two fractions according to their water content, separately concentrating the two liquor fractions, mixing and concentrating said fractions, adding 2 volumes of water to them, concentrating the mixture obtained, separating out the insoluble impurities by sedimentation, pre-crystallizing the ferulic acid and/or its salts with a synthetic purification resin, crystallizing out the ferulic acid and/or its salts, separating the ferulic acid and/or its salts from the crystallization mother liquors and drying it and screening it.
