Manufacturing Process
Citric acid is neutralised with a controlled amount of sodium hydroxide or sodium carbonate to form trisodium citrate solution. The solution is decolourised, filtered and crystallised under vacuum, then dried and screened to obtain Trisodium Citrate Dihydrate with consistent assay and particle size. Each batch is tested for assay, pH, water content and heavy metals.
