Description
Summary:Nowadays, membrane-based technologies (e.g. microfiltration, ultrafiltration, nanofiltration, membrane distillation, and pervaporation) have demonstrated to meet the requirements to be involved in different food and bioproduct processes. Several applications have been developed, including either separation, recovery or concentration of bioactive molecules from agro-food products and by-products, treatment of natural extracts, recovery of aromas from natural and processed products, production of non-alcoholic beverages, as the most popular ones. Therefore, the goal of this review is to give a comprehensive outlook of the latest developments focused on the separation, fractionation and concentration of several bioactive compounds contained in their original sources, as well as the food processes-assisted by membrane technologies. Throughout this review, ongoing literature has been analysed, discussing the relevant insights according to the type of membrane-based separation process, properties of molecules, membrane features and key factors influencing the separation performance of those technologies. Specific applications have been analysed and discussed, highlighting typical advantages and drawbacks over conventional technologies. •Membrane-based technologies as emerging tool to recovering functional molecules.•Tight UF and NF membranes as the high efficiency extraction of phenolic molecules.•Membrane distillation assists the concentration of valuable molecules.•Pervaporation meets the requirements for the selective extraction of aromas.
