Recovery technologies for water-soluble bioactives: advances in membrane-based processes

In this chapter, an overview of membrane separation systems in the food industry is provided. Basic principles of pressure-driven membrane operations are described, together with some key advantages and shortcomings compared to conventional technologies. Selected applications of membrane unit operations and integrated membrane systems in specific areas of agro-food production (dairy, soybean, fish processing, olive oil) are also reviewed and discussed, highlighting their potential with respect to the separation, concentration and purification of high-added-value compounds, improvement in food quality and the reduction of environmental pollution.
