Technical Document

Brief Overview
Calcium citrate is a calcium salt of citric acid. The physical appearance of calcium citrate is a white powder easily soluble in water. Calcium citrate consists of 24.1% calcium citrate anhydrous and 21.1% calcium citrate tetrahydrate by mass. Generally, this compound is found in canned cheeses, biscuits, waffles, pancakes, etc. It is used as a food additive, a preservative, and a flavor. Furthermore, calcium citrate can also be taken as a supplement because of its high content of calcium.

Manufacturing Process

The production process starts with the fermentation process in which a carbohydrate source is used, such as corn-based starch. The fermentation was then purified using a precipitation process that involved lime in producing a calcium citrate solid. Then, the mixture was treated with sulfuric acid to produce partial purified soluble citric acid. The final step was to separate the mixture to obtain calcium citrate.
