Sodium benzoate

Ukusetyenziswa Sodium benzoate ngakumbi yaziwa ngokuba ukutya additive (E211), nto leyo zicacisa kwiqela kwisigcinakaliso. Oku - sodium benzoate. Ngaphandle, umchiza yi ngumgubo emhlophe leyo ayinavumba, okanye inokuba ngevumba encinci benzaldehyde.

arhente Okokuqala Kwafunyanwa 1875 yi umphengululi waseMerika Hyugo Flekom ke kwakhona ezicetyisiweyo indawo salicylic acid. Sele ngowe-1908, sodium benzoate eUnited States wavunyelwa ukuba usebenzise njenge ukubola. wesenzo ukubola isekelwe kwinto yokuba benzoate sodium uyakwazi ukunciphisa kakhulu umsebenzi enqanda anokufumaneka esiseleni, nebonelela reactions redox, yaye ngaloo ndlela ziyakwehlisa ngokubonakalayo impumelelo igwele kunye ukungunda fungi. amanyathelo olunjalo kwisigcinakaliso abayinqobo potassium sorbate kunye sodium benzoate. Kukho imali encinane yale compound ekutyeni zendalo. Phakathi kwezi, ungakhankanya ama-apile, zeerasintyisi, lwemostade, kunye nabanye.

Ifomula chemical ukwimo - C6H5COONa, kodwa yinto inxaki empirically lithathwe.

Njengoko isongezelelo ukungondleki, libhaliswe phantsi inombolo inxalenye (E211), sodium benzoate sivunyelwe ukusetyenziswa kumazwe amaninzi ehlabathini jikelele, kuquka eRashiya. Abaziingcali ngexesha elinikiweyo ingxoxo esebenzayo kwi iingozi zempilo kwezinto zidityanisiwe, eziquka sodium benzoate, kunye nedayi ngaxeshanye. Inyaniso kukuba unike ubungqina yenzululwazi ngomonakalo ezinokubangelwa yi yokusebenzisana iidayi benzoate E110, E104, kunye nabanye.

Sisetyenziswa ngokubanzi imveliso mveliso, ingakumbi yokudla. Apha asisetyenziswa lokulondolozwa inyama kunye neemveliso zentlanzi, imajarini, iintlobo ezahlukeneyo mayonnaise kunye isoso. Ukuba ukusebenzisa sodium benzoate ekutyeni eziqulathe ukwakheka uVithamin C, intsebenziswano kunye nabo kungakhokelela ekubeni zoqhaphelo eyingozi ophezulu benzene carcinogen.

Njengoko ukubola, sodium benzoate ezisetyenziswa xa kusenziwa izithambiso kunye amalungiselelo amayeza. Kwimeko yokugqibela, iba yinxalenye expectorants kunye nezinye iziyobisi idityanisiwe injongo enjalo.

Gcobisa ukusetyenziswa sodium benzoate kunye iinjongo zobugcisa. Ngokomzekelo, xa eyama kulo asetyenziswa component engundoqo Ipeyinti ukukhuselwa kwimiphumo eziyingozi kwiindawo ezahlukeneyo airframe moya eyenziwe aluminium. Ukongeza, ukuba isicelo njengokuba nesingxobo -mveliso eyahlukeneyo enxulumene nale nkqubo.

Pyrotechnic izinto injongo kwezopolitiko ngamandla ayo asekelwe isandi rocket wayisusa.

Ngowe-1999, sebhayoloji P. Piper kwenye yemisebenzi yakhe wacebisa ukuba benzoate, phantsi yintshukumo iiseli igwele, kunokubangela ebizwa ngokuba "uxinezeleko oxidative". Kwakhona kwathiwa malunga ubukho kweziyobisi umsebenzi mutagenic, nto leyo isasazwa kakhulu kwi-DNA yomntu. Apha kuyimfuneko ukwenza isicelo sokuba Piper iphicothwe kungekuphela nje izenzo sodium benzoate, kodwa nezinye ii-asidi eziphilayo, ezithi zisetyenziswe kwisigcinakaliso.

Kamva, le nzulu uthi umonakalo esinxulunyaniswa ne phambi benzoate, ezinxulumene ingozi yesifo Parkinson kaThixo.

Ngokungqinelana neemfuno WHO ebekwe CICAD26 ka-2000, uphononongo olwahlukahlukeneyo kufuziselo uhlobo yempembelelo sodium benzoate kwi abantu yabonisa ngokhuseleko olubonakalayo lwe ezimbaxa. Noko ke, olu xwebhu ubonisa ukuba iimeko kwenzeka ulusu allergies (dermatitis), kwakunye andzise isifuba.
