Characteristics and uses of tricalcium phosphate
Jan 18, 2024Tricalcium phosphate is a safe nutritional fortifier, mainly added to foods to enhance calcium intake, and can also be used to prevent or treat symptoms of calcium deficiency. At the same time, tricalcium phosphate can also be used as an anti caking agent, pH regulator, buffering agent, etc. in food. Such as flour anti caking agent (dispersant), additive for milk powder, candy, pudding, seasoning, meat, animal oil refining agent, yeast feed, etc.
character
Tricalcium phosphate is a mixture of different types of calcium phosphate, with an approximate composition of 10CaO · 3P2O5 · H2O and a molecular weight of 1004.64. White amorphous powder. Odorless and tasteless. Stable in the air. Relative density 3.18. Melting point 1670 ℃. The refractive index is 1.63. Insoluble in ethanol and acetone. Almost insoluble in water (0.0025g/100ml). Easily soluble in dilute hydrochloric acid and nitric acid.
purpose
Tricalcium phosphate can be used as an acidity regulator, buffering agent, anti caking agent, acidity regulator, nutritional enhancer (fortified calcium), aroma enhancer, yeast feed, diluent for plant-based extracts, refining agent for animal oil, and stabilizer.
