Calcium lactate CAS 814-80-2

Specification

Application

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 approximately 14% calcium. it is used to stabilize and improve the texture of canned fruits and vegetables by converting the labile pectin to the less solu- ble calcium pectate. it thereby prevents structural collapse during cooking. it is used in angel food cake, whipped toppings, and meringues to increase protein extensibility which results in an increase of foam volume. it is also used in calcium fortified foods such as infant foods and is used to improve the properties of dry milk powder.

Storage

Calcium lactate can exist in a number of hydration states, which are characterized as anhydrous, monohydrate, trihydrate, and pentahydrate. Dehydration of the pentahydrate form is rapid at temperatures of 558℃ and above. Dehydration is reported to be accompanied by some loss of crystallinity. Tablet crushing strength was reported to be reduced following dehydration of calcium lactate pentahydrate.
