High rate ultrafiltration of soymilk

Abstract Permeation rates were higher by approximately 650% and 350% for the 500 000 and 100 000 hollow fibre membranes respectively when compared with those achieved using the 50 000 molecular weight cut-off membrane. The final products after diafiltration assayed: 52.7%, 51.3% and 51.7% protein for the 50 000, 100 000 and 500 000 membranes respectively and 29.2%, 28.4% and 33.4% fat for the same membranes.
