Abstract:
1. A method of producing a crystalline form of sucrose having a melting point of 150° C., comprising the steps of: (a) dissolving sucrose in water and heating the sucrose in a temperature controlled water bath at 60° C. to obtain a saturated sucrose solution, wherein the saturated sucrose solution contains 2.873 g of sucrose per 1 mL of water; (b) preheating methanol to be added into said saturated sucrose solution at 60° C. with stirring and adding the preheated methanol to said saturated sucrose solution to obtain a mother liquor in a ratio of 5:1 methanol/water while maintaining the reaction at 60° C.; (c) keeping said mother liquor motionless to obtain a crystal and filtering said mother solution after said crystallization to obtain a re-crystallized sucrose; and (d) hot-drying said re-crystallized sucrose in a vacuum oven at a temperature of between 30° C. and 40° C., wherein said re-crystallized sucrose has a melting point of 150° C.
