Orthophosphoric acid (Phosphoric acid, orthophosphoric acid, E338)
Orthophosphoric (phosphoric) asidi ndi pawiri kuchokera m'gulu la inorganic, asidi ofooka. M'magulu ovomerezeka a zakudya zowonjezera, orthophosphoric acid ili ndi code E338, ndi ya gulu la antioxidants (antioxidants), ndipo imagwiritsidwa ntchito ngati chowongolera acidity.
Chemical formula H3PO4. Pa kutentha pamwamba pa 213 ° C, imasinthidwa kukhala pyrophosphoric acid H4P2O7. Bwino kwambiri sungunuka m'madzi.
Makhalidwe ambiri a E338
Orthophosphoric acid ali ndi zotsatirazi thupi katundu - crystalline mankhwala popanda mtundu ndi fungo, bwino sungunuka mu zosungunulira madzi, nthawi zambiri ntchito mu mawonekedwe a madzimadzi (85% amadzimadzi njira ya orthophosphoric acid). Orthophosphoric acid imapezeka mwamankhwala kuchokera ku phosphate kapena hydrolysis (calorizator). Orthophosphoric acid imadziwika ndi mtengo wotsika (ngati ikuyerekeza, mwachitsanzo, ndi citric acid), choncho imagwiritsidwa ntchito nthawi zambiri popanga zakudya ndi zakumwa.
Kuopsa kwa Orthophosphoric acid
Choyipa chachikulu cha E338 pathupi la munthu ndikuwonjezera acidity, potero kusokoneza kuchuluka kwa acid-base, chifukwa chake, zinthu zomwe zili ndi E338 ziyenera kugwiritsidwa ntchito mosamala kwambiri kwa anthu omwe ali ndi gastritis yokhala ndi acidity yayikulu, makamaka - kuwapatula pazakudya. . Malinga ndi madokotala, Orthophosphoric asidi ali ndi katundu leaching kashiamu m'thupi, amene ali kwambiri zoipa kwambiri chikhalidwe cha dzino enamel ndi fupa minofu, kuchititsa caries ndi osteoporosis. Kugwiritsa ntchito kwambiri E338 kumayambitsa matenda am'mimba, nseru komanso kusanza.
Kugwiritsa ntchito E338
Monga chowongolera cha acidity, Orthophosphoric acid imagwiritsidwa ntchito m'makampani azakudya kuti apatse zinthu zowawa kapena zowawa pang'ono. Amagwiritsidwa ntchito popanga zakumwa zoziziritsa kukhosi, tchizi zophikidwa, mitundu ina ya soseji ndi ufa wophika.
Ntchito zina za Orthophosphoric acid: mano, cosmetology, ndege ndi mafakitale opanga mankhwala, kupanga zotsukira ndi otembenuza dzimbiri. Mu ulimi, Orthophosphoric acid ndi gawo la mitundu yambiri ya feteleza.
Ntchito E338
Pa gawo la dziko lathu, kugwiritsa ntchito Orthophosphoric acid kumaloledwa, kutsatira miyezo yovomerezeka yovomerezeka ndiyovomerezeka.
