Notes:
Ion exchange whey protein concentrate (IEWPC) was produced from acid whey using Spherosil-S, a microporous silica bead cation exchange medium. About 80% of the total whey proteins were recovered by the ion exchange process. The composition of IEWPC was 63 - 66% protein, 1 - 2% lactose, 7 - 9% milkfat and 20 - 22% ash. Solubility, PAGE, reverse phase HPLC and Sephadex gel frltration results confirmed that the proteins in IEWPC had undergone substantial denaturation during their isolation. Several major problems encountered during the study were: generation of large volumes of column effluent, the need for concentration of column protein elutate fractions by ultrafiltration, column fouling and loss of protein solubility and functionality.
