I-Tripotassium phosphate K3PO4 CAS 7778-53-2 izinga lokudla
Incazelo Yomkhiqizo
I-Potassium phosphate iyi-reagent enamandla aphezulu okuvimba, Isebenza njenge-ejenti yokuvimba ukulawula i-pH, Ngokuvamile isetshenziswa njengengxenye yezinhlobo eziningi zemidiya ezisetshenziswa ekukhuleni kwama-microorganisms, njengengxenye ku-phosphate buffered saline (PBS). Kwenzeka ngezindlela eziningana: i-monobasic, i-dibasic, kanye ne-tribasic (K3PO4). Iningi lezixazululo ze-potassium phosphate buffer ezingathathi hlangothi ze-pH ziqukethe izingxube zezinhlobo ze-monobasic neze-dibasic ngamazinga ahlukahlukene, kuye nge-pH oyifunayo. Ama-Gomori buffers, ama-phosphate buffers asetshenziswa kakhulu, aqukethe ingxube ye-monobasic dihydrogen phosphate kanye ne-dibasic monohydrogen phosphate. Ngokushintsha inani likasawoti ngamunye, uhla lwe-buffers lungalungiswa ukuthi lubambe kahle phakathi kwe-pH 5.8 kanye ne-pH 8.0 (sicela ubheke amathebula angezansi). Ama-phosphates anamandla aphezulu okuvimba futhi ancibilika kakhulu emanzini.

Isicelo
1) I-Potassium phosphate iwumlawuli we-acidity kanye ne-chelating agent (esetshenziselwa ukubopha ama-ion ensimbi). Ivimbela ukubola futhi isetshenziswa njengesiqinisi se-acid kuma-powder kanye nokuvimbela ukwakheka kwama-clumps. Yandisa umsebenzi wama-antioxidants.
2) Embonini yokudla (izithasiselo zokudla), isetshenziswa njenge-emulsifier, i-potassium fortifier, i-flavouring agent, i-meat binder. I-Potassium phosphate isiza ekuqiniseni, ekujiyiseni nasekulawuleni i-acidity kanye nomswakama ekudleni. Ngokusho kwe-FAO (1984), ukusetshenziswa kwayo kanye nenani elilinganiselwe kunjengoba kungezansi: umhluzi osheshayo; usawoti we-phosphate ophelele: 1000 mg/kg (kubalwa ngokusekelwe ku-P2O5); imilenze yangaphambili yengulube ephekiwe, i-ham, inyama egayiwe ephekiwe 3g/kg (inani lokusetshenziswa okukodwa noma inani elihlanganisiwe nenye i-phosphate, ebalwa ku-P2O5); ubisi oluyimpuphu oluqinile oluphansi, ubisi oluhlanganisiwe, ukhilimu oncibilikisiwe: 2 g/kg (inani lokusetshenziswa okukodwa); inani lokuhlanganiswa nenye i-stabilizer: 3 (kubalwa ngento engenamanzi); ubisi oluyimpuphu, ushizi ocutshunguliwe: 5g/kg; ushizi ocutshunguliwe, inani eliphelele le-phosphate 9g/kg (kubalwa njenge-phosphorus); isiphuzo esibandayo: 2g/kg (inani lokusetshenziswa okukodwa noma inani elihlanganisiwe nenye i-phosphate, ebalwa ku-P2O5).
3) Ingasetshenziswa ekulungiseleleni imikhiqizo ye-pasta ngamanzi ane-alkaline. Ingasetshenziswa ekwenzeni insipho ewuketshezi, iphepha elisezingeni eliphezulu, uphethiloli ocolisisiwe, iphepha elisezingeni eliphezulu, njenge-phosphorus kanye nomanyolo we-potassium. Ingasetshenziswa njengesithambisi samanzi ebhoyila. Isetshenziswa futhi kwezokwelapha. I-Potassium phosphate ngezinye izikhathi isetshenziswa njengomuthi. Ingaba nomphumela wokukhipha isisu futhi isebenze njengesiqeda ukuvuvukala uma isetshenziswa ngamanani emithi. Kodwa-ke, i-phosphorus ingasebenzisana neminye imithi, okuhlanganisa ama-corticosteroids kanye nama-potassium-sparing diuretics, okwandisa ingozi yemiphumela emibi; yisebenzise kuphela uma welulekwa udokotela.
4) Ingasetshenziswa njenge-reagent yokuhlaziya, i-buffer kanye ne-softener.
