The invention relates to an edible table sweetening material, in particular to a sugar-free low-calorie table sweetening material. The sugar-free low-calorie table sweetening material is prepared from the following composition ingredients in percentage by weight: 10 to 25 percent of erythritol, 52 to 68 percent of isomalt, 12 to 32 percent of maltitol, 0.3 to 1.6 percent of high-rate sweetening agents, 1.2 to 3.5 percent of bonding agents and 0.3 to 1.2 percent of sweet taste modification materials. The sugar-free low-calorie table sweetening material is prepared through the following process steps of preparing a mixed solution of a bonding agent and a sweetening material; performing homogenizing; taking and crushing the erythritol, the isomalt and the maltitol; putting the materials into a fluidized bed; sequentially spraying the mixed solution of the bonding agent and the sweetening material; obtaining a crude product of a fluffy particular sugar-free low-calorie table sweetening material; sequentially passing the sugar-free low-calorie table sweetening material through a sieve being 40 meshes and a sieve being 50 meshes; taking the materials between 40 and 50 meshes for bulk density detection; taking the materials with the bulk density between 400 and 500g/L to obtain the sugar-free low-calorie table sweetening material. The sugar-free low-calorie table sweetening material has the advantages that the preparation is simple and convenient; the operation is easy; the sweet degree is 2 to 10 times of that of the ordinary cane sugar.
