Preparation Method
Sodium malate is generally prepared by reacting malic acid with sodium hydroxide or sodium carbonate, and then further processing to obtain the finished product. For example, malic acid is first dissolved in water, and then sodium carbonate is added, and the reaction generates sodium malate which precipitates out.
