Abstract
The study examines the use of ultrafiltration and microfiltration membranes for concentrating isoelectric soya protein. Experiments with an unstirred batch cell indicate that the flux is limited by the protein which remains in solution after precipitation of the major proportion. The porosityof the precipitate cake formed is shown to be a second important factor. A significant improvement in flux can be obtained by using membranes which permit passage of the soluble protein and by increasing the precipitate particle size. The results are shown to be within the range predicted theoretically by the two limiting cases of a particulate model and a soluble protein model.This publication has 17 references indexed in Scilit:
