Calcium malate is the calcium salt of malic acid (E 296) and a food additive .

Extraction and presentation

Calcium malate can be obtained by reacting malic acid with calcium carbonate .

{\ displaystyle \ mathrm {C_ {4} H_ {6} O_ {5} + CaCO_ {3} \ longrightarrow CaC_ {4} H_ {4} O_ {5} + CO_ {2} + H_ {2} O}}

use

Calcium malate is used in the food industry as an additive or acidity regulator E 352 (e.g. in potato chips). This makes use of the fact that malic acid is released in a controlled manner, depending on the environment, so that the acidity of the food remains relatively constant. As a natural cell component, malic acid and its salts (malates) are considered harmless. The amount ingested with food is incorporated into the metabolism. In chemistry it is used as a buffer reagent.
