Claim Text:
1. 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 then cooled down to between 20 and 30° C., (c) the solution is held at this temperature for a period of from 0.5 to 5 h, (d) subsequently, the solution is re-heated to between 35 and 40° C., (e) the solution is held at this temperature for a period of from 0.5 to 5 h, (f) subsequently, the solution is cooled down to about 10° C. to form precipitated alpha-lactose crystals, and (g) optionally, the precipitated alpha-lactose crystals are separated from the solution.
