Tripotassium phosphate K3PO4 CAS 7778-53-2 kalasi ya chakudya
Mafotokozedwe Akatundu
Potaziyamu phosphate ndi reagent yokhala ndi mphamvu yayikulu yotetezera, Imagwira ntchito ngati chotetezera kuti ilamulire pH, Nthawi zambiri imagwiritsidwa ntchito ngati gawo la mitundu yosiyanasiyana ya zinthu zomwe zimagwiritsidwa ntchito popanga tizilombo toyambitsa matenda, monga gawo la phosphate buffered saline (PBS). Imapezeka m'njira zosiyanasiyana: monobasic, dibasic, ndi tribasic (K3PO4). Ma solution ambiri a pH osalowerera ndale a potassium phosphate amakhala ndi zosakaniza za mitundu ya monobasic ndi dibasic mpaka madigiri osiyanasiyana, kutengera pH yomwe mukufuna. Ma Gomori buffers, omwe amagwiritsidwa ntchito kwambiri ndi phosphate buffers, amakhala ndi chisakanizo cha monobasic dihydrogen phosphate ndi dibasic monohydrogen phosphate. Mwa kusintha kuchuluka kwa mchere uliwonse, mitundu yosiyanasiyana ya ma buffers imatha kukonzedwa bwino pakati pa pH 5.8 ndi pH 8.0 (chonde onani matebulo omwe ali pansipa). Ma phosphates ali ndi mphamvu yayikulu yotetezera ndipo amasungunuka kwambiri m'madzi.

Kugwiritsa ntchito
1) Potaziyamu phosphate ndi mankhwala owongolera acidity ndi chelating agent (omwe amagwiritsidwa ntchito pomangirira ayoni achitsulo). Amaletsa kuumitsa ndipo amagwiritsidwa ntchito ngati acid stabilizer mu ufa komanso kupewa kupanga ma clumps. Amawonjezera ntchito ya antioxidants.
2) Mu makampani azakudya (zowonjezera zakudya), imagwiritsidwa ntchito ngati emulsifier, potassium fortifier, flavouring, ndi meat binder. Potassium phosphate imathandiza kukhazikika, kukhuthala ndikuwongolera acidity ndi chinyezi muzakudya. Malinga ndi zomwe FAO (1984) ikupereka, momwe imagwiritsidwira ntchito komanso kuchuluka kwake kochepa ndi motere: msuzi wachangu; mchere wonse wa phosphate: 1000 mg/kg (wowerengedwa kutengera P2O5); miyendo yakutsogolo ya nkhumba yophikidwa, nyama yankhumba, nyama yodulidwa yophikidwa 3g/kg (kuchuluka kogwiritsidwa ntchito kamodzi kapena kuchuluka kosakanikirana ndi phosphate ina, yowerengedwa pa P2O5); ufa wochepa wa mkaka, mkaka wokometsedwa, kirimu wosungunuka: 2 g/kg (kuchuluka kogwiritsidwa ntchito kamodzi); kuchuluka kophatikizana ndi chokhazikika china: 3 (chowerengedwa pa chinthu chopanda madzi); ufa wa mkaka, tchizi chokonzedwa: 5g/kg; tchizi chokonzedwa, kuchuluka konse kwa phosphate 9g/kg (chowerengedwa ngati phosphorous); chakumwa chozizira: 2g/kg (kuchuluka kogwiritsidwa ntchito kamodzi kapena kuchuluka kosakanikirana ndi phosphate ina, yowerengedwa pa P2O5).
3) Ingagwiritsidwe ntchito pokonza zinthu za pasitala ndi madzi amchere. Ingagwiritsidwe ntchito popanga sopo wamadzimadzi, mapepala apamwamba, mafuta oyeretsedwa, mapepala apamwamba, monga phosphorous ndi feteleza wa potaziyamu. Ingagwiritsidwenso ntchito ngati chofewetsa madzi a boiler. Imagwiritsidwanso ntchito mu zamankhwala. Potassium phosphate nthawi zina imagwiritsidwa ntchito ngati mankhwala. Imatha kukhala ndi mphamvu yokoka komanso kugwira ntchito ngati mankhwala ofewetsa thupi ikagwiritsidwa ntchito ngati mankhwala. Komabe, phosphorous imatha kuyanjana ndi mankhwala ena, kuphatikizapo corticosteroids ndi potassium-sparing diuretics, zomwe zimawonjezera chiopsezo cha zotsatirapo zoyipa; igwiritseni ntchito pokhapokha ngati dokotala akulangizani kutero.
4) Ingagwiritsidwe ntchito ngati chothandizira kusanthula, chosungira ndi chofewetsa.
