Electrodialysis and ion exchange processes; the case of milk whey
Boer, R. de; Robbertsen, T.
Progress in food engineering: 393-403
Topics covered in this review are: manufacture of a demineralized whey by electrodialysis (process conditions and pre-treatment); recent developments in the demineralization of whey by ion exchange; processing of ultrafiltration permeate by ion exchange resins (manufacture of lactose and manufacture of a lactose-hydrolysed syrup); and whey protein recovery by ion exchange resins. Some new research is reported including: studies of the influence of process conditions and pretreatments on demineralization rate, 'power' efficiency and overall yield during electrodialysis of Gouda cheese whey; and studies on the decalcification and decolorization of the ultrafiltration permeate of Gouda whey during lactose manufacture.
