Holistic valorization of rapeseed meal utilizing green solvents extraction and biopolymer production with Pseudomonas putida

A rapeseed meal (RSM) valorization scheme was developed to utilize valuable fractions including phenolics (mainly sinapic acid), proteins and polysaccharides. This involved solvent extraction of phenolics, alkali extraction of proteins and fermentation of residual polysaccharide using Pseudomonas putida. For the first time, sustainable Deep eutectic solvents (DESs) were used in the extraction of rapeseed meal phenolics. With yields up to 85.69 %...
