Recovery, concentration and purification of phenolic compounds by adsorption: A review

Processing of solutions containing phenolics by adsorption-desorption enables the recovery and purification of bioactive compounds or fractions from plant. This work reviews the equilibrium and kinetic principles of adsorption, as well as the adsorption/desorption processing of solutions containing phenolic compounds. The description of relevant applications such as food-oriented processes, detoxification of fermentation media, color removal, and purification of sugar solutions and microbial metabolites is included.
