Abstract:

Gallic acid is an interesting natural compound because of its antioxidant, anti-inflammatory, antifungal and antitumor properties. It is present in relatively high concentrations in a number of biomass sources and in industrial wastes from where it could be extracted. Aiming at developing benign and efficient extraction and purification processes for gallic acid, aqueous two-phase systems (ATPS) composed of ionic liquids (ILs) and inorganic salts were investigated. The present investigation was focused on improving the feasibility of large scale applications of a solid phase extraction (SPE) procedure dedicated to the recovery of polyphenols. Adsorption of polyphenol (gallic acid) on an anion exchange resin, Amberlite IR-400 was studied for purification of polyphenols from the pomegranate peel. The work was carried out to understand how the processing parameters can be manipulated to optimize the purification of gallic acid for its further use in nutraceutical and functional foods. In this work the effect of pH, temperature, speed of agitation and concentration for gallic acid adsorption on anion exchange resin was studied.
