The selective precipitation of ␣-lactalbumin (␣-LA) at a pH around its isoelectric point (4.2) under heat treatment is the basis for a fractionation process of whey proteins. In these conditions, ␤-lactoglobulin remains soluble, whereas bovine serum albumin and immunoglobulins co-precipitate. Knowle
