What is Trisodium citrate dihydrate？
Sodium citrate, also known as sodium citrate, sodium citrate, and trisodium citrate, has the molecular formula Na3C6H5O7·2H2O and a molecular weight of 294.1. It is a colorless crystal or white crystalline powder product, odorless, salty, and cool. It loses crystal water at 150℃ and decomposes at higher temperatures. It is slightly deliquescent in humid air and weatherable in hot air. It is easily soluble in water and glycerin, insoluble in ethanol, and insoluble in alcohols and other organic solvents. Sodium citrate is non-toxic, has pH adjustment properties and good stability, so it can be used in the food industry. Sodium citrate is used as a food additive with the largest demand. It is mainly used as a flavoring agent, buffer, emulsifier, swelling agent, stabilizer and preservative. In addition, sodium citrate is compatible with citric acid and is used in various jams, Gelling agents, nutritional supplements and flavors for jelly, juice, beverages, cold drinks, dairy products and cakes.
