Tripotassium phosphate K3PO4 CAS 7778-53-2 matakin abinci
Bayanin Samfurin
Potassium phosphate wani abu ne mai aiki da ƙarfin buffering mai yawa, Yana aiki a matsayin wakili mai buffering don daidaita pH, Ana amfani da shi azaman sashi don nau'ikan hanyoyin sadarwa iri-iri da ake amfani da su a cikin al'adun ƙananan halittu, a matsayin wani ɓangare a cikin phosphate buffered saline (PBS). Yana faruwa a cikin siffofi da yawa: monobasic, dibasic, da tribasic (K3PO4). Yawancin mafita na potassium phosphate buffer na pH sun ƙunshi cakuda nau'ikan monobasic da dibasic zuwa matakai daban-daban, ya danganta da pH da ake so. Gomori buffers, waɗanda aka fi amfani da su a cikin phosphate buffers, sun ƙunshi cakuda monobasic dihydrogen phosphate da dibasic monohydrogen phosphate. Ta hanyar bambanta adadin kowane gishiri, ana iya shirya nau'ikan buffers waɗanda ke buffering sosai tsakanin pH 5.8 da pH 8.0 (da fatan za a duba teburin da ke ƙasa). Phosphates suna da ƙarfin buffering mai yawa kuma suna narkewa sosai a cikin ruwa.

1) Potassium phosphate wani sinadari ne mai daidaita acidity da kuma chelating (wanda ake amfani da shi wajen ɗaure ƙarfe ions). Yana hana bushewa kuma ana amfani da shi azaman mai daidaita acid a cikin foda da kuma hana samuwar dunƙulewar abubuwa. Yana ƙara yawan aikin antioxidants.
2) A masana'antar abinci (ƙara abinci), ana amfani da shi azaman emulsifier, mai ƙarfafa potassium, mai ƙara dandano, mai ɗaure nama. Potassium phosphate yana taimakawa wajen daidaita, kauri da daidaita acidity da danshi a cikin abinci. Dangane da tanadin FAO (1984), amfani da shi da iyakataccen adadin shine kamar haka: broth nan take; jimlar gishirin phosphate: 1000 mg/kg (an ƙididdige shi bisa ga P2O5); ƙafafuwan alade da aka dafa, naman alade, nama da aka niƙa da aka dafa 3g/kg (adadin amfani ɗaya ko adadin haɗin tare da sauran phosphate, an ƙididdige shi bisa ga P2O5); ƙarancin foda madara mai yawa, madara mai tauri, kirim mai narkewa: 2 g/kg (adadin amfani ɗaya); adadin haɗin tare da sauran mai daidaita: 3 (an ƙididdige shi akan abu mai ruwa); foda madara, cuku mai sarrafawa: 5g/kg; cuku mai sarrafawa, jimlar adadin phosphate 9g/kg (an ƙididdige shi azaman phosphorus); abin sha mai sanyi: 2g/kg (adadin amfani ɗaya ko adadin haɗin tare da sauran phosphate, an ƙididdige shi bisa ga P2O5).
3) Ana iya amfani da shi wajen shirya kayayyakin taliya da ruwan alkaline. Ana iya amfani da shi wajen ƙera sabulun ruwa, takarda mai inganci, man fetur mai inganci, takarda mai inganci, kasancewar takin phosphorus da potassium. Ana iya amfani da shi azaman mai laushin ruwa a cikin tukunya. Hakanan ana amfani da shi a magani. Ana amfani da potassium phosphate wani lokacin azaman magani. Yana iya samun tasirin diuretic kuma yana aiki azaman maganin laxative idan aka yi amfani da shi a adadi mai yawa na magani. Duk da haka, phosphorus na iya hulɗa da wasu magunguna, gami da corticosteroids da magungunan diuretics masu adana potassium, wanda ke ƙara haɗarin illa; yi amfani da shi kawai lokacin da likita ya ba da shawarar yin hakan.
4) Ana iya amfani da shi azaman reagent na nazari, buffer da kuma mai laushi.
