Barometric membrane technologies

Proteins, hydrolysates and peptides from both animal and vegetable sources exhibit specific biological activities, which may have effect on functional or pro-health properties of food products. Among the available technologies, membrane filtration is one of the most sustainable and cost-effective technique for the recovery and purification of protein-based compounds. This chapter provides a comprehensive overview on the use of barometric membrane processes, also in integrated systems, for the recovery of protein-based compounds from different sources (cereals, oilseeds, microalgae, soy, agro-food by-products, among others) highlighting typical advantages and limitations over competitive techniques.
