Sodium nitrite (E-250) - incazelo, ukusetshenziswa, umphumela emzimbeni

Sodium nitrite (eyayivame, kwesokudla -. Sodium nitrate noma sodium nitrite) isetshenziswa embonini njengoba a okufakiwe ukudla (njengoba uyakulondoloza). umphumela umdlavuza (ngokuvumelana abanye abameleli imithi okwaziyo avuse umdlavuza). sodium nitrite e isoseji nezinye (mhlawumbe inyama) imikhiqizo is njengoba E-250 ezaziwayo.

Nezivimbelakuvunda yalolu hlobo anezikhombo E-200 kanye no-E-229. Bona ukuvimbela (noma kunalokho, kakhulu ukubambezela) kabusha isikhunta namagciwane ahlukahlukene. Ingqikithi is hhayi kuphela asetshenziswe emikhiqizweni inyama, kodwa iwayini - njengendlela yokuthola kokuma nokuvuthwa iwayini (magciwane).

Sodium nitrite - crystal- (kusuka ophuzi ukukhanya powder emhlophe). Hygroscopic, kahle oncibilikayo emanzini. Lapho wadalula mpilo (hhayi enqwabelene) kancane kancane oxidized ukuba NaNO3 (sodium nitrate). ejenti enamandla kakhulu ekunciphiseni. Cha.

Lezi zifundo wembula lokhu: nitrite sodium, uxhumana amino acid phezu Ukushisa unika umdlavuza lapho iyakhona ingqondo ukuthuthukiswa zomdlavuza, kuhlanganise umdlavuza wamathumbu and obstructive isifo samaphaphu.

Kungani, ngokuba yingozi ngakho, i-sodium nitrite elikhona imikhiqizo ngokufaka izimakethe ezitolo? Ngo umkhakha isetshenziswa ngezinhloso ezilandelayo:

- njengoba i antioxidant enikeza umbala "kungokwemvelo" inyama nenhlanzi;
- ukushintsha izimo ukwelashwa ukushisa (esikhundleni 100 ° C iba ukwelashwa eyanele at 72 ° C - ukulondoloza etholwe ephoqelela);
- njengenhlangano izidakamizwa elwa namagciwane ngokumelene Clostridium botulinum (agent causative of botulism). Phela, lo yokugcina iba imbangela lokudakwa ezinzima, okuholela kulimaze ukuze isimiso sezinzwa.

Ukungabikho izithasiselo ukunikeza imikhiqizo shades ugly kusuka eluhlaza kuya ensundu grey - umbala, ngokusobala azibangelwa iphango. Kusukela ezinjalo "ubuhle" hhayi wonke umuntu wayefuna ukwenza narezochka futhi ikakhulukazi n redlozhit izivakashi zayo. Nokho, ngisho lokhu ukuthi ayibalulekile. Ayikho enye izidakamizwa akunakwenzeka ukuyeka ukukhula kwamagciwane ayingozi. It kuvela ukuthi ngesikhathi kungekho E-250 ayikwazi akhishwa. Yini okumelwe uyenze? Zilungiselele! Iqiniso lokuthi uzilungiselela kube yizinhlamvu futhi ngokunembile fresh ngaphandle izithasiselo. A ezihlongozwayo ifektri izibiliboco ungakwazi pamper ngokwakho ngezikhathi imiqulu nesizotha. Kulokhu, awukwazi ukhathazeke ukuthi impilo sodium nitrite umonakalo.

Sodium nitrite (GOST 19906-74, m osch 4-7-3) sengezwe isakhiwo ukhonkolo njengenhlangano inhibitor ka AK (ukugqwala asemkhathini); lisetshenziswe zamagama organic; ukufunwa uginindela nephepha, yokusansimbi, imithi, amakhemikhali umkhakha.

NaNO2 ekhona diazo udayi asetshenziswe ukudaya imicu yemvelo (kuhlanganise ukuphupha) ekukhiqizeni rubbers ngoba phosphating (zensimbi) ukususa ithini. ajwayelekile kakhulu naye bezithombe usebenzisa Antioxidants ngesikhathi ukubonakaliswa isibhamu. Nge ezinengqondo indlela sodium nitrite kuba izidakamizwa kakhulu Uphakamisa zibe emathunjini, esakaza bronchi (vasodilator, bronchodilator), uba laxative, futhi ngesikhathi esifanayo kuba alikaziwa ikhambi lobuthi bama-cyanide ubuthi icala.
