    摘要: A method for improving the yield of the production of crystalline alpha-lactose is suggested, wherein (a) an aqueous lactose solution is gradually cooled down to about 10° C., (b) a first amount of precipitated alpha-lactose crystals is separated from the mother liquor, (c) an amount of a carbohydrate compound is added to the mother liquor such that the solubility product of the lactose is exceeded at the given temperature, (d) a second amount of precipitated alpha-lactose crystals is separated from the mother liquor, and (e) both amounts of alpha-lactose crystals are combined.
