ʻO ka waikawa Orthophosphoric (ʻApika phosphoric, ʻākena orthophosphoric, E338)
ʻO ka Orthophosphoric (phosphoric) kahi waikawa mai kahi mahele o ka inorganic, acid acid nāwaliwali. I ka ʻae ʻae ʻia o nā mea hoʻohui meaʻai, aia i ka orthophosphoric acid ka code E338, no ka hui o nā antioxidants (antioxidants), a hoʻohana ʻia ma ke ʻano he regulator acidity.
Kumumea kemikala H3PO4. I nā mahana ma luna o 213 ° C, hoʻohuli ʻia ia i ka waikawa pyrophosphoric H4P2O7. Hiki ke hoʻoheheʻe maikaʻi ʻia i ka wai.
Nā ʻano laulā o E338
Loaʻa i ka Orthophosphoric acid kahi mau ʻano o ke kino - kahi waiwai crystalline me ka ʻole o ke kala a me ka ʻaʻala, hiki ke hoʻoheheʻe maikaʻi ʻia i nā mea hoʻoheheʻe wai, hoʻohana pinepine ʻia ma ke ʻano o kahi wai syrupy (85% wai aqueous solution o ka orthophosphoric acid). Loaʻa ʻia ʻo Orthophosphoric acid i ka chemically mai phosphate a i ʻole e ka hydrolysis (calorizator). Hoʻohālikelike ʻia ka waikawa Orthophosphoric e kahi kumu kūʻai haʻahaʻa (inā hoʻohālikelike ʻia, e laʻa me ka waikawa citric), no laila hoʻohana pinepine ʻia i ka hana ʻana i nā meaʻai a me nā mea inu.
Ka hōʻino ʻana o ka waikawa Orthophosphoric
ʻO ka hopena maikaʻi ʻole o ka E338 i ke kino o ke kanaka, ʻo ia ka hoʻonui ʻana i ka acidity, a laila e hoʻopau ai i ke koena o ka acid-base, no laila e hoʻohana ʻia nā huahana i loaʻa iā E338 me ka akahele loa i ka poʻe me ka gastritis me ka acidity kiʻekiʻe, kūpono loa-e haʻalele iā lākou mai ka ʻai. . Wahi a nā kauka, ʻo Orthophosphoric acid ka waiwai o ka leaching calcium mai ke kino, kahi hopena maikaʻi ʻole i ke kūlana o ka enamel niho a me ka iwi iwi, e hoʻoulu ai i ka caries a me ka osteoporosis. ʻO ka hoʻohana nui ʻana i ka E338 ke kumu o ka maʻi ʻōpū, nausea a me ka luaʻi.
Noi o E338
Ma ke ʻano he mea hoʻoponopono o ka acidity, hoʻohana ʻia ka waika Orthophosphoric i ka ʻoihana meaʻai e hāʻawi i nā huahana i kahi ʻono ʻawaʻawa a ʻawaʻawa paha. Hoʻohana ʻia ia i ka hana ʻana i nā mea inu ʻoluʻolu carbonated, nā paʻakai i hana ʻia, kekahi ʻano huahana sausage a me ka pauka bakena.
Nā noi ʻē aʻe o ka Orthophosphoric acid: kahua niho, cosmetology, nā mokulele a me nā ʻoihana lāʻau lapaʻau, hana ʻana i nā mea holoi a me nā mea hoʻololi popo. I ka mahiʻai, ʻo ka Orthophosphoric acid kahi ʻāpana o nā ʻano nui o nā mea kanu.
Hoʻohana o E338
Ma ka panalāʻau o ko mākou ʻāina, ʻae ʻia ka hoʻohana ʻana i ka waikawa Orthophosphoric, pono ka mālama ʻana me nā pae i ʻae ʻia o ka hoʻohana.
