Embodiment 1

[0130] Example 1: Preparation of Granular Compositions and Formulations

[0131] 64.816 parts of white sugar, 0.4 parts of DL-malic acid, 0.4 parts of dibutyl hydroxytoluene, 24 parts of trehalose hydrate, 1 part of olopatadine hydrochloride, 5 parts of acesulfame potassium, 2 parts of dextrin, light 0.25 parts of quality anhydrous silicic acid, 0.44 parts of edetate sodium hydrate, and 1.06 parts of hydroxypropyl cellulose (HPC) were put into the stirring granulator. A granulation solution prepared by separately dissolving 0.44 parts of HPC and 0.004 part of thaumatin in 5 parts of purified water was put thereinto, and granulated. After the granulation, wet mass sizing was carried out with a crushing and sizing machine, and drying was carried out at 45° C. to obtain a granulated dry product 1 . The granulated dry product 1 was charged into a crushing and sizing machine with a mesh of 1000 μm, and the granules were sized to obtain the sized product 1 . The granulated product...
