Abstract:
     The process of this invention is: alkali solution is added dropwise into lactose solution after it is heated and dissolved, and it is isomerized. Then its pH value is adjusted with hydrochloric acid, decolourized, desalted with resin, concentrated by vacuum, cooled, separated, and disinfected. By this invention, the conversion rate of lactose into lactofructose may be as high as over 40 percent. Its technology is simplified, it does not pollute environment.
