A process for preparing stable anhydrous lactose products comprising the compound crystal form of the alpha form and the beta form of lactose. An unstable anhydrous lactose product is heated, at atmospheric or sub-atmospheric pressure, at low water vapor pressure, and while avoiding overheating, to a temperature in the range of from 100 DEG C. to 220 DEG C., and the product is kept at that temperature until crystallization of the compound crystal form of the alpha form and the beta form of lactose occurs. |
