- A method for preparation of magnesium-malic acid
-
The invention discloses a method for preparing magnesium malate. The method comprises the following steps: dissolving L-malic acid with deionized water, heating to 75-85 DEG C, adding magnesium carbonate or magnesium oxide step by step in batches, then heating to 105-120 DEG C, and stirring until magnesium carbonate or magnesium oxide is completely dissolved; decolorizing and filtering a reaction solution, carrying out concentration and crystallization on the filtrate at reduced pressure, and thus obtaining magnesium malate crystals. The rate of chelation of the magnesium malate prepared by the method is significantly increased, and the quality of the magnesium malate can be remarkably improved.
