Method for crystallizing anhydrous fructose from its aqueous solutions |
摘要 |
Methods of crystallizing anhydrous fructose from aqueous solutions using a large scale crystallizer are provided. The various crystallization methods include at least a cooling crystallization step wherein cooling is controlled so as to maintain a temperature difference between the solution and the cooling element of less than about 10° C., and maintain supersaturation of the aqueous solution with respect to the saturated fructose at a ratio between 1.1 and 1.25, whereby optimum heat transfer and a fructose crystal growth rate of at least 0.008 mm/hr is achieved with little or no spontaneous crystal nucleation.
