Basic principles of membrane technology  Advantages of membrane technologies in the food and beverage industry  Membrane types used in the food and beverage industry and industrial scale applications Membrane technologies are widely used in the food and beverage industry, especially in the production and processing of milk and dairy products, fruit juices and alcoholic beverages.Figure A. Basic scheme of a membrane process.Purpose: This review article includes detailed information about the advantages of membrane technologies used in the food and beverage industry compared to traditional methods, the basic principles of membrane technologies, membrane types, common application areas, and studies reported in the literature. Theory and Methods:The uses of (i) membrane separation, (ii) evaporation and (iii) freeze-concentration techniques are investigated for purification, separation and concentrated product preparation in the food and beverage industry. Results:Membrane processes are a more advantageous method than traditional methods to obtain high quality and cost-effective products in the food and beverage industry. Conclusion:The application of membrane processes as an alternative to traditional separation, purification, and concentrated product methods for "sustainable production" and "zero waste approach" in the food and beverage industry is a very popular and growing subject. Pressure-driven membrane processes, namely MF, UF, NF, and RO, lead to effective separation of components with a large range of particle sizes. Hence, this paves the way to find a wide range of membrane applications in the food and beverage industry. In addition, since membrane processes are more economical in terms of energy consumption compared to traditional techniques, it is predicted that their use will have an increasing trend.

“…The use of pressure‐driven membrane processes has the advantage of less energy consumption, less extraction time, and high separation efficiency depending of the type of membrane . As previously mentioned, the separation efficiency also depends on the physicochemical composition of the extract (e.g., the molecular weight and the concentration of the solutes), characteristics of the membrane (e.g., the material, the configuration, the porosity, and the nature) and the operating conditions of the filtration process (e.g., transmembrane pressure and feed flow) …”

“…Typically, MF has been used to remove organic matter and recover carbohydrates and proteins; UF has been applied to obtain specific compounds such as inulin and several high‐added value compounds (see Table ), whereas the NF has allowed to extract organic compounds with low molecular weight polyphenols (e.g., polyphenols), which are of interest in cosmetic and food industries. Table reports some of the compounds extracted from vegetables sources in the last decade, in which can be seen that UF process has been most used for this purpose.…”

The production of specific metabolites using microorganism has been promoted and enhanced by two different approaches, such as modification of the metabolic pathways of microorganism and optimization of culture medium conditions to synthesize specific compounds. However, research community is today focused on the development of processes and techniques for a suitable recovery of metabolites from different stages of fermentation. For this purpose, the use of organic solvents has been the most common approach for the recovery of specific target compounds according to the solvent affinity. Additionally, these techniques also require the implementation of unit processes to obtain better recovery rates; it means that solvent extraction methods need the implementation of additional steps to recover the solvents used, which may involve the increase of final costs in the production process. For this reason, researchers have started to consider membrane-based technologies (e.g. microfiltration [MF], ultrafiltration [UF], and nanofiltration [NF]), as an alternative for the recovery of metabolites from fermentation broths. Therefore, the objective of this paper is to provide an overview of the current findings of the recovery of metabolites from fermentation broths by means of pressuredriven membrane processes. Particular attention will be paid to relevant data, analyzing and discussing according to the membrane features, metabolite properties, and some other phenomena that influence in the separation.Moreover, a framework of the application of the MF, UF, and NF processes in solutes recovery is addressed. Finally, some fundamentals of these processes are also given.
