Orthophosphoric acid (phosphoric acid, orthophosphoric acid, E338)
Orthophosphoric (phosphoric) acid haɗuwa ce daga nau'in inorganic, acid mai rauni. A cikin karɓaɓɓun kayan abinci, orthophosphoric acid yana da lambar E338, yana cikin ƙungiyar antioxidants (antioxidants), kuma ana amfani dashi azaman mai sarrafa acid.
Kayan sunadarai H3PO4. A yanayin zafi sama da 213 ° C, an canza shi zuwa pyrophosphoric acid H4P2O7. Mai narkewa sosai cikin ruwa.
Janar halaye na E338
Orthophosphoric acid yana da abubuwa masu amfani na zahiri - abu mai ƙyalƙyali ba tare da launi da ƙanshi ba, mai narkewa a cikin abubuwan ƙanshin ruwa, galibi ana amfani da shi a cikin ruwa mai yaƙinsa (kashi 85% na ruwa na orthophosphoric acid). Orthophosphoric acid ana samun sa ne ta hanyar sinadarai daga sinadarin phosphate ko kuma na hydrolysis (calorizator). Orthophosphoric acid yana da halin ƙarancin kuɗi (idan an kwatanta shi, misali, tare da citric acid), saboda haka ana yawan amfani dashi wajen samar da abinci da abubuwan sha.
