AB Phenolic compounds are of considerable interest due mainly to their antioxidantactivity. They constitute a large family of compounds that can be found in cereals, fruitsor vegetables, and present potential commercial applications in the food, health andcosmetic industries. By extracting them from waste materials, we are contributing notonly to reduce but also to revalorize the residues.Wheat bran is an abundant and underused byproduct from the milling industry,whose main phenolic compound is ferulic acid (FA). It can be found in three forms:soluble free (F-FA), soluble conjugated (C-FA) and insoluble bound form (B-FA), beingthe major part in the insoluble bound form, esterified to the arabinoxylans (AX) andother cell wall structural components (≈92%). Hence, new processes are required tobreak these bonds in order to recover it in high quantities.In this study, two different techniques have been applied and compared with theaim of maximizing the extraction of FA from wheat bran: in the first one pressurizedwater (PW) is used as solvent and in the second one supercritical water (SCW) hasbeen tested.
