Abstract
Dry food quality protein and lactose powders are produced from cheese whey by sequential ultrafiltration processes, each of which removes as permeate substantial amounts of water and dissolved solids from the respective concentrates. In the initial protein recovery process, the concentrated protein fraction is pasteurized to inhibit bacterial growth and is evaporated to produce a protein substance which is palatable, highly soluble in water and rich in essential amino acids. The lactose concentration step produces a fine quality sweetner of excellent solubility and food value. Temperatures and pressures are carefully controlled in the first two processing operations. A third operation removes additional solid material which can be easily disposed of and a fourth operation reduces the BOD of the remaining liquid fraction to the point that it can be discharged into rivers or streams. The overall process is highly energy efficient when compared to other processes of treating whey to recover nutrients and reduce pollution.
