Abstract
Lactose having reproducible pH and a lowered ash level can be produced from lactose rich permeate resulting from the ultrafiltration of whey, by adding a small amount of a chelating agent such as a salt of ethylenediaminetetraacetic acid as, for instance, the disodium salt, the calcium disodium salt, or an alkali metal polyphosphate, as sodium hexametaphosphate to the lactose containing permeate prior to crystallization of the lactose.
