Bayanin Samfura
Sodium tripolyphosphate (STP, wani lokacin STPP ko sodium triphosphate ko TPP) wani fili ne na inorganic tare da dabara Na5P3O10. Sodium triphosphate shine gishirin sodium na polyphosphate penta-anion, wanda shine tushen haɗin gwiwa na triPhosphoric Acid.Sodium tripolyphosphate an samar da shi ta hanyar dumama cakuda stoichiometric na Disodium phosphate, Na2HPO4, da Monosodium Phosphate, NaH2PO4, ƙarƙashin yanayin kulawa da hankali.
Abubuwan da ake amfani da su na sodium tripolyphosphate kuma sun haɗa da yin amfani da shi azaman abin kiyayewa. Ana iya amfani da sodium Tripolyphosphate STPP don adana abinci kamar jan nama, kaji, da abincin teku, yana taimaka musu su riƙe taushi da danshi. Abincin dabbobi da abincin dabbobi an san ana bi da su tare da sodium triphosphate, suna yin amfani da maƙasudi iri ɗaya kamar yadda ake yi a cikin abincin ɗan adam.
