Abstract
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.
