增加乳糖产量的方法（二）

Method for increasing the yield in lactose production (II)
Abstract:
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.
Abstract(Chinese):

提高结晶α-乳糖制备中的产率包括：（a1）将乳糖水溶液逐渐冷却至10℃; （a2）从母液中分离出第一量沉淀的α-乳糖晶体; （a3）将母液与一定数量的碳水化合物混合，使得溶液中仍存在剩余量的乳糖的溶解度积超过; （a4）从母液中分离出第二量的沉淀的α-乳糖晶体; 和（a5）组合两个水平的α-乳糖晶体。 包括用于制备结晶性α-乳糖的独立权利要求，包括使乳清进行分离过程，其中获得富含蛋白质的级分和富含乳糖的级分，任选地在浓缩后使富含乳糖的级分进行去矿化过程 沉淀微溶盐，任选地在进一步浓缩之后冷却去矿质残留物，直到乳糖以结晶形式沉淀，步骤（a1） - （a4），将乳糖水溶液与一定数量的碳水化合物混合，使得 超过乳糖在溶液中的溶解度积，逐渐将乳糖溶液冷却至10℃，并从母液中分离出沉淀的α-乳糖晶体的量。
