Summary

Whey protein solutions of different chemical compositions were filtered through a large pore size ultrafiltration membrane (molecular mass cut-off 100 kDa). The influences of pH, ionic environment and Ca chelation on the performance characteristics of the membrane (filtration rate, total and individual whey protein permeability) were examined. Increase in pH in the range 5·0-10·0 resulted in a gradual increase in filtration rate and individual whey protein permeability. The presence of Ca in the whey protein solution had a negative effect on the performance characteristics of the membrane. Addition of EDTA to protein solution improved the filtration rate but had no effect on the protein permeation. Fractionation of the low molecular mass whey proteins (β-lactoglobulin and α-lactalbumin) from high molecular mass proteins (bovine serum albumin, lactoferrin and immunoglobulins) was best achieved at pH 8·0.
