Description
Technical field
The present invention designs a kind of production technique of tricalcium phosphate, particularly relates to a kind of production method of the tricalcium phosphate that uses as foodstuff additive.
Background technology
Tricalcium phosphate (TCP/ Tricalcium phosphate) is white unformed powder, and the mixture by different calcium phosphate are formed roughly consists of 10CaO3P
2O
5H
2O, molecular weight 1004.64.The white amorphous powder, odorless, tasteless.Relative density 3.18.Be insoluble in water, be soluble in dilute hydrochloric acid and nitric acid.Stable in the air.
In foodstuffs industry, make raising agent, dough conditioning agent, anti-caking agent, buffer reagent, pH regulator agent, texturizers, solidifying agent, accessory substance, sequestrant etc.As make roasting product, cake raising agent.The fermentation-assisting agent that bread, cake are opened, buffer reagent, pectin solidifying agent (gelation), yeast food meat product texturizers etc.Be used for brewageing, can increase saccharogenic power, improve fermentation capacity.As a kind of safe nutritional reinforcer, mainly be added on the absorption of strengthening calcium in the food, also can be used for preventing or treating the symptom of calcium deficiency.
