Saccharin sodium, also called soluble saccharin, is the sodium salt of saccharin and it is a dihydrate matter. It is colorless crystal or slight white crystal powder, and it is easy to lose crystallization water into waterless saccharin, white powder, odorless or little aroma, thick taste and sweet with bitter. The sugariness is about 500 times as cane sugar. The heat resistance and the alkali resistance are weak, and the sweet taste will be lost under the thermal acid condition. When the content of it is more than 0. 026%, the solution is bitter. The present granule condition of domestic manufacturer: 4-6mesh, 5-8 mesh, 8-12mesh, 8-16mesh, 10-20mesh, 20-40mesh, 40-80mesh, 80-100mesh. The usages: 1, food: general drinking, jelly, fruit jelly, egg white and sugar, etc. 2, feed additives: feed for pig, fragrant and sweet agent, etc. 3, daily chemical industry: tooth paste, mouthwash, eyedrop, etc. 4, galvanization industry: galvanized brightener. Instruction: the chemical name of saccharin is 1,2-benzisothiazol-3-one 1,1-dioxide. It is a kind of artificial synthesis sweetener widely used in global market with the advantages of low cost and high sugariness, and the sugariness is 300-500 times as cane sugar. Owing to the solubility of saccharin in water is low, the saccharin sodium was chosen in the national additive standard, and when the amount is large, it is bitter.
