Abstract

Suggested is a method for improving the yield during the production of crystalline alpha lactose, wherein

(a) an aqueous lactose solution is adjusted to a temperature of between about 62 and 67° C.,(b) the solution is cooled down to between about 20 and 30° C.,(c) the solution is held at this temperature for 0 to 5 h,(d) subsequently, the solution is re-heated to between about 30 and 35° C.,(e) the solution is held at this temperature for 0 to 5 h,(f) then the solution is cooled down to about 10° C. and(g) subsequently, the precipitated alpha lactose crystals are separated from the second mother liquor,(h) an amount of a carbohydrate compound is added to the second mother liquor such that the solubility product of the residual amount of lactose that is still soluble is exceeded,(i) the second amount of precipitated alpha lactose crystals is separated from the mother liquor, dried, and(j) both amounts of alpha lactose crystals are combined.
