It is used in conjunction with ascorbate or erythorbate derivs. as a cure accelerator in processed meat products Trisodium citrate, sometimes referred to simply as sodium citrate, possesses a saline, mildly tart flavor. Sodium citrate is chiefly used as a food additive E331, usually for flavor or as a preservative. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. Sodium citrate is common as an ingredient in Bratwurst, lemon-lime and citrus soft drinks, such as Ting, Chinotto, and some Ocean Spray juices, contributing to their tart tastes, and can also be found in such energy drinks as Rockstar and Red Bull. 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, trisodium salt 2-Hydroxy-1,2,3-propanetricarboxylic acid, trisodium salt Citnatin Citreme Citric acid trisodium salt Citrosodine E331 FEMA 3026 Natrocitral Sodium citrate Trisodium citrate Trisodium citrate hydrate C6H8Na3O7 261.0928 260.996311635 trisodium 2-hydroxypropane-1,2,3-tricarboxylic acid trisodium citric acid 68-04-2 [Na+].[Na+].[Na+].OC(=O)CC(O)(CC(O)=O)C(O)=O InChI=1S/C6H8O7.3Na/c7-3(8)1-6(13,5(11)12)2-4(9)10;;;/h13H,1-2H2,(H,7,8)(H,9,10)(H,11,12);;;/q;3*+1 HRXKRNGNAMMEHJ-UHFFFAOYSA-N belongs to the class of organic compounds known as tricarboxylic acids and derivatives.
