Ko te Phosphate tetahi o nga kai taiao o te nuinga o nga kai katoa, ka whakamahia nuitia ki te tukatuka kai hei whakauru kai nui me te taapiri mahi. Ko te toka phosphate te toka phosphate (kei roto te calcium phosphate). Ka tauhohe te waikawa sulfuric ki te toka phosphate ki te whakaputa i te konupūmā dihydrogen phosphate me te konupūmā pūkawa ngāwha ka taea e te tipu ki te hanga phosphate. Ka taea te wehea te Phosphates ki te orthophosphates me te polycondensed phosphates: ko nga phosphates e whakamahia ana ki te tukatuka kai ko te nuinga o te konutai, te konupūmā, te pāhare pāporo, me te rino me te tote zinc hei whakapakari matūkai. Ko nga momo phosphates e whakamahia ana i te nuinga o te waa Neke atu i te 30 nga momo. Ko te konutai phosphate te momo kai nui o te kai phosphate o te kainga. Na te whanaketanga o te hangarau tukatuka kai, kei te piki haere te kai o te konupora phosphate i ia tau.
