Calcium lactate is often found in aged cheeses. Small crystals of it precipitate out when lactic acid is converted into a less soluble form by the bacteria active during the ripening process.
In medicine, calcium lactate is most commonly used as an antacid and also to treat calcium deficiencies. Calcium lactate can be absorbed at various pHs and does not need to be taken with food for absorption for these reasons.
Calcium Lactate is the calcium salt of lactic acid which is soluble in water. it has a solubility of 3.4 g/100 g of water at 20°c and is very soluble in hot water. it is available as a monohydrate, trihydrate, and pentahydrate. the trihydrate and pentahydrate have solubili- ties of 9 g in 100 ml of water at 25°c.
It contains About 14% calcium. It stabilizes and improves the texture of canned fruits and vegetables by converting unstable pectin into insoluble calcium pectate.Therefore, it prevents structural collapse during cooking. It is used in angel food cakes, whipped toppings and meringues to increase the stretchability of the protein, which in turn increases foam volume. It is also used in calcium-fortified foods such as baby food and to improve the properties of milk powder.
Calcium lactate is used in pharmaceutical formulations as bioavailability enhancers and nutritional supplements.
Calcium lactate has been used in preparations for the treatment of calcium deficiency.
Used as a calcium supplement for fish and birds;
as a feed additive.
