Date Dec. 21, 1995A process for fractionation of dairy whey is described which enables various whey constituents, in particular, alpha-lactalbumin and beta-lactoglobulin, to be recovered in substantially pure form. Lactose may also be recovered. The mineral content of raw whey is reduced so that the calcium content is less than 120 parts per million. Thereafter, the whey is treated to allow the lactose to crystallize out for removal and selectively to flocculate the alpha-lactalbumin, leaving a liquor containing substantially pure beta-lactoglobulin.
