Fabrication and Performance of Low-Fouling UF Membranes for the Treatment of Isolated Soy Protein Solutions

Consumers are becoming more conscious about the need to include functional and nutritional foods in their diet. This has increased demand for food extracts rich proteins peptides with physiological effects that used within pharmaceutical industries. Among these protein extracts, soy its derivatives highlighted. Isolated (ISP) presents a content of at least 90%. Wastewaters generated during production process contain small (8–50 kDa), it would be desirable find recovery treatment compounds. Ultrafiltration membranes (UF) fractionation concentration solutions. By appropriate selection membrane pore size, larger retained concentrated while carbohydrates minerals mostly recovered permeate. The accumulation macromolecules proximity surface generates one most important limitations inherent technologies. In this work, three UF based on polyethersulfone (PES) were fabricated. two them, polyethylene glycol (PEG) was added formulation as fouling prevention. evaluated by study flux decline models Hermia’s mechanisms.
