ferulic acid extraction process, use of ferulic acid obtained through the extraction process, and process to produce natural vanillin

摘要

process for extracting ferulic acid, use of ferulic acid obtained through the extraction process, and process for producing natural vanillin a process for extracting ferulic acid present in an aqueous phase, obtained by treating at least one plant material, and also containing polysaccharides, wherein said process comprises at least the following steps: 1) treating said plant material succeeded by a solid / liquid separation to recover a solid phase and an aqueous liquid phase comprising the ferulic acid and said polysaccharides, 2) treating said liquid phase to selectively separate, on the one hand, polysaccharides and, on the other hand, ferulic acid present in an aqueous fraction, 3) the concentration of said aqueous fraction containing ferulic acid to recover a stream with concentrated ferulic acid, 4) solid ferulic acid recovery gone 1/1
