The invention consists of the following procedures: (1) Prepare the supersaturated erythritol solution (2) Add the high sweetener to the supersaturated erythritol solution (3) Co-crystallize the erythritol: continue to cool the supersaturated erythritol solution mixed with the high sweetener and thus obtain the co-crystalline product of the erythritol and the high sweetener (4) Co-crystallized erythritol is dried by the heat of crystallization in the crystallization process and under normal circumstances requires no further drying. If necessary, the product may be dried in the range of 40-60 . The erythritol cocrystalline of different sizes may be obtained by sieving. The present invention takes advantage of the excellent crystallinity of the erythritol and binds the high sweetener and the erythritol together through co-crystallization. The invention improves the sweetness of the erythritol and featuers stable sweetness, uniform content and simple process.
