A process for producing whey derived products suitable for use in infant food formulas from edible cheese whey. The cheese whey is subjected to ultrafiltration to produce a protein-rich retentate and a lactose-rich permeate. The permeate is then partially demineralized as by electrodialysis, and blended with the protein-rich retentate. Also products produced by the process.

Modified whey product and process including ultrafiltration and

A high yield of relatively pure lactose and salt products are produced from a permeate resulting from ultrafiltration of whey by precipitating calcium and citrate salts from the permeate without substantial precipitation of phosphate salts by concentrating the permeate to a solids content of about 40 to 45% and holding at about 180.degree. to 200.degree. F. for 30 to 90 minutes, removing precipitated solids from the permeate and then further concentrating the permeate and crystallizing and removing lactose.
