Abstract
The invention is directed to a method for recovering lactose from an aqueous lactose solution comprising a concentration step, wherein water is removed from the aqueous lactose solution by freezing out water at a temperature below the eutectic temperature of the aqueous lactose solution and at a lactose concentration higher than the eutectic concentration of the aqueous lactose solution, thereby obtaining a concentrated lactose solution; and a crystallization step, wherein at least part of the concentrated lactose solution is subjected to crystallization at a temperature above the eutectic temperature of the concentrated lactose solution, thereby obtaining lactose crystals.
Claims15
A method for recovering lactose from an aqueous lactose solution, the method comprising:
- (a) concentrating the aqueous lactose solution, wherein water is removed from the aqueous lactose solution by freezing out water at a temperature below the eutectic temperature of the aqueous lactose solution and at a lactose concentration higher than the eutectic concentration of the aqueous lactose solution, thereby obtaining a concentrated lactose solution;
- and
- (b) crystallizing the lactose, wherein at least part of the concentrated lactose solution is subjected to crystallization at a temperature above the eutectic temperature of the concentrated lactose solution, thereby obtaining lactose crystals.
