I-Tripotassium phosphate K3PO4 CAS 7778-53-2 uhlobo lokutya
Ingcaciso yeMveliso
I-Potassium phosphate yi-reagent enekhono eliphezulu lokukhusela, Isebenza njenge-arhente yokukhusela ukulawula i-pH, Isetyenziswa njengenxalenye yeentlobo ngeentlobo zemidiya esetyenziswa kwinkcubeko yee-microorganisms, njengenxalenye kwi-phosphate buffered saline (PBS). Ivela kwiindlela ezahlukeneyo: i-monobasic, i-dibasic, kunye ne-tribasic (K3PO4). Uninzi lwezisombululo ze-potassium phosphate buffer ze-pH ezingenayo i-pH ziquka imixube ye-monobasic kunye ne-dibasic ukuya kumanqanaba ahlukeneyo, kuxhomekeke kwi-pH efunekayo. Ii-Gomori buffers, ii-phosphate buffers ezisetyenziswa kakhulu, ziquka umxube we-monobasic dihydrogen phosphate kunye ne-dibasic monohydrogen phosphate. Ngokutshintsha ubungakanani betyuwa nganye, uluhlu lwee-buffers lungalungiswa kakuhle phakathi kwe-pH 5.8 kunye ne-pH 8.0 (nceda ubone iitheyibhile ezingezantsi). Ii-Phosphates zinamandla aphezulu okukhusela kwaye zinyibilika kakhulu emanzini.

Isicelo
1) I-Potassium phosphate yi-acidity regulator kunye ne-chelating agent (esetyenziselwa ukubopha ii-ion zesinyithi). Ithintela ukubola kwaye isetyenziswa njenge-acid stabilizer kwimigubo kunye nokuthintela ukwakheka kwamaqoqo. Yonyusa umsebenzi wee-antioxidants.
2) Kwishishini lokutya (izongezo zokutya), isetyenziswa njenge-emulsifier, i-potassium fortifier, i-flavouring agent, i-meat binder. I-potassium phosphate inceda ukuzinzisa, ukutyeba kunye nokulawula i-acidity kunye nokufuma ekutyeni. Ngokwesibonelelo se-FAO (1984), ukusetyenziswa kwayo kunye nomlinganiselo olinganiselweyo ngolu hlobo lulandelayo: umhluzi okhawulezileyo; ityuwa ye-phosphate iyonke: 1000 mg/kg (ibalwa ngokusekelwe kwi-P2O5); imilenze yangaphambili yengulube ephekiweyo, iham, inyama egayiweyo ephekiweyo 3g/kg (ubungakanani bokusetyenziswa okukodwa okanye ubuninzi bokudibanisa kunye nenye i-phosphate, ebalwa kwi-P2O5); ubisi oluxutyiweyo oluphantsi, ubisi oluqunqiweyo, i-dilute cream: 2 g/kg (ubungakanani bokusetyenziswa okukodwa); ubuninzi bokudibanisa kunye nezinye iziqinisi: 3 (zibalwa kwi-anhydrous substance); ubisi oluyimpuphu, itshizi ecutshungulweyo: 5g/kg; itshizi ecutshungulweyo, ubuninzi be-phosphate buyi-9g/kg (zibalwa njenge-phosphorus); isiselo esibandayo: 2g/kg (ubungakanani bokusetyenziswa okukodwa okanye ubuninzi bokudibanisa kunye nenye i-phosphate, ebalwa kwi-P2O5).
3) Ingasetyenziselwa ukulungisa iimveliso zepasta ngamanzi ane-alkaline. Ingasetyenziselwa ukwenza isepha elulwelo, iphepha elikumgangatho ophezulu, ipetroli ecociweyo, iphepha elikumgangatho ophezulu, njenge-phosphorus kunye nezichumisi ze-potassium. Ingasetyenziselwa ukuthambisa amanzi ebhoyila. Ikwasetyenziswa nakwizonyango. I-potassium phosphate ngamanye amaxesha isetyenziswa njengeyeza. Inokuba nefuthe lokudambisa kwaye isebenze njengeyeza lokukhulula isisu xa isetyenziswa ngobuninzi bezonyango. Nangona kunjalo, i-phosphorus inokunxibelelana namanye amayeza, kuquka ii-corticosteroids kunye ne-potassium-sparing diuretics, nto leyo eyonyusa umngcipheko wemiphumo emibi; yisebenzise kuphela xa ucetyiswe ngugqirha.
4) Ingasetyenziswa njenge-analytical reagent, i-buffer kunye ne-softener.
