Sodium benzoate

Into sodium benzoate ngaphezulu njengoba ukudla eyaziwa okufakiwe (E211), okuyinto libhekwa iqembu nezivimbelakuvunda. Lokhu - sodium benzoate. Ngaphandle, kwakwakhe kuyinto powder emhlophe okuyinto ayinaphunga, noma kungaba iphunga kancane benzaldehyde.

ejenti Okokuqala etholwe ngo-1875 yi-isazi American futhi Hyugo Flekom liphinde aphakanyisiwe njengendlela esikhundleni salicylic acid. Kakade ngo-1908, i-sodium benzoate e-United States wayevunyelwe ukusebenzisa njengoba uyalondoloza. uyalondoloza isenzo sayo sisekelwe iqiniso lokuthi benzoate sodium uyakwazi kakhulu wehlise umsebenzi enzyme ukuthi zikhona kuseli, okunikeza ukusabela redox, futhi ngaleyo ndlela kakhulu ukunciphisa ukusebenza imvubelo kanye isikhunta isikhunta. Lezo kuyinto nezivimbelakuvunda eyinqaba potassium sorbate kanye sodium benzoate. Kukhona inani elincane lokhu kwakwakhe ukudla yemvelo. Phakathi kwalezi, ungacacisa apula, omisiwe, lwesinaphi, kanye nabanye.

Ifomula amakhemikhali izidakamizwa - C6H5COONa, kodwa kuyinto kwesibalo empirically etholakala.

Njengoba ibhekwa wezokudla, ezibhaliswe ngaphansi inombolo okuyingxenye (E211), i-sodium benzoate ivunyelwe ukusetshenziswa emazweni amaningi emhlabeni wonke, kuhlanganise eRussia. Ongoti isikhathi esinikeziwe nengxoxo asebenzayo phezu eziyingozi kakhulu empilweni izidakamizwa kuhlangene, okuhlanganisa i-sodium benzoate, futhi abanye odayi kanyekanye. Iqiniso liwukuthi banikezwe ubufakazi besayensi ngomonakalo kungadalwa nokuxhumana udayi E110 benzoate, E104, nabanye.

Kabanzi asetshenziswa ekukhiqizeni izinto zezimboni, ikakhulukazi embonini yezokudla. Lapha isetshenziswa lokulondolozwa inyama kanye nenhlanzi imikhiqizo, imajarini, izinhlobo ezehlukene imayonnaise isoso. Uma ukusetshenziswa sodium benzoate e nokudla okune ukubunjwa Vitamin yayo C, ukuxhumana nabo kungaholela lokuhlala esiyingozi eziphakeme benzene umdlavuza.

Njengoba uyakulondoloza, i-sodium benzoate asetshenziswe ekukhiqizeni kwezimonyo ezithaka imithi amalungiselelo. Kulo mBhalo, kuba ingxenye expectorants nezinye izidakamizwa elihlangene ngenjongo ezinjalo.

Sabalalisa ukusetshenziswa sodium benzoate nangezinjongo lobuchwepheshe. Ngokwesibonelo, e zezindiza ke asetshenziselwa njengoba Isakhi esiyinhloko ezinengilazi ukuba asivikele emiphumeleni elimazayo ahlukahlukene izindiza airframe izingxenye ezenziwe aluminium. Ngaphezu kwalokho, isicelo njengoba Plating kulezo zimboni ezihlobene nale nqubo.

Pyrotechnic izinto injongo itholakala ikhono layo ukulingisa umsindo rocket kokuthatha off.

Ngo-1999, isazi sezinto eziphilayo P. Piper kwelinye imisebenzi wakhe esikisela ukuba benzoate, ngaphansi isenzo kwamaseli imvubelo, kungabangela okuthiwa "ukucindezeleka oxidative". Kwathiwa kushiwo mayelana nokuba khona izidakamizwa umsebenzi mutagenic, elithengiswa ngokuyinhloko kuyi-DNA yomuntu. Lapha kubalulekile ukwenza ukubhuka ukuthi Piper uhlole hhayi kuphela njengoba izenzo sodium benzoate, kodwa futhi nezinye acid organic, ezisetshenziswa njengoba nezivimbelakuvunda.

Kamuva, isazi sesayensi wathi umonakalo kungenzeka ukuthi umataniswe nokuba khona benzoate, elihlobene ne ingozi Parkinson.

Ngokuhambisana nezidingo UBANI ebekwe CICAD26 ka 2000, izifundo ezihlukahlukene uhlobo ithonya sodium benzoate abantu yabonisa ukuphepha eyisihlobo kwakwakhe. Nokho, lo mbhalo uveza ukuthi izimo kungenzeka aleji (dermatitis), kanye babhebhethekisa somoya.
