Dicalcium Phosphate, Dihydrate yog ib qhov chaw ntawm calcium thiab phosphorus uas tseem ua haujlwm ua lub khob noom cookie txias thiab tshuaj dawb.Nws ua haujlwm raws li lub khob noom cookie txias hauv cov khoom bakery, ua cov tshuaj dawb huv hauv cov hmoov nplej, ua cov calcium thiab phosphorus hauv cov khoom noj, thiab ua cov calcium rau alginate gels.Nws muaj kwv yees li 23% calcium.Nws yog xyaum insoluble nyob rau hauv dej.Nws tseem hu ua dibasic calcium phosphate, dihydrate thiab calcium phosphate dibasic, hydrous.Nws yog siv nyob rau hauv cov khoom qab zib gels, ci khoom, cereals, thiab noj tshais cereals.
Dicalcium phosphate dihydrate tsuas yog me ntsis soluble ntawm qhov kub thiab txias ntawm kev sib xyaw thiab tuav cov khob noom cookie thiab batters.Yog li ntawd, nws tsis tso acidity rau cov tshuaj tiv thaiv nrog dej qab zib kom txog thaum lig rau theem ci, thaum kub nce mus txog 135 txog 140 ° F.Txij li thaum DCP·2H20 tsis pib hnov mob hauv qab 135 ° F, thiab cov qauv sab hauv ntawm cov khoom ci pib khov ntawm li 160 ° F, cov khoom uas ci sai yuav tsis muab sijhawm txaus rau kev tso tawm tag nrho C02.DCP·2H2 0, yog li ntawd, tsis tuaj yeem siv rau hauv biscuits, pancakes lossis ib yam khoom ci uas tau ci tag nrho hauv tsawg dua 20 min.
Dicalcium phosphate dihydrate tsis tshua siv los ntawm nws tus kheej hauv cov txheej txheem leavening tab sis feem ntau yog ua ke nrog cov tshuaj acidic phosphates sai dua.Nws cov ntawv thov loj yog nyob rau hauv cov khoom qab zib sib tov, cov khob cij khov khov, thiab lwm yam khoom uas xav tau ib nrab teev lossis ntau dua los ua kom tiav ci.Nws muaj tus nqi nruab nrab qis, thiab yog li ntawd ntau DCP·2H20 yuav tsum ua kom tsis txhob muaj cov dej qab zib ntau dua li lwm cov phosphate-leavening acids.
