Sodium benzoate ndi mankhwala otetezedwa omwe amagwiritsidwa ntchito mobwerezabwereza mu zipatso zam'mimba, mapiritsi , zakumwa, saladi, zolembedwanso, ndi zakudya zopatsa thanzi - zakudya zomwe zili ndi pH yochuluka. Zakudya zamakono, monga sodium benzoate zimagwiritsidwa ntchito mobwerezabwereza mu zakudya zowonongeka kuti zisawononge kukula kwa mabakiteriya, yisiti kapena tizilombo tina tizilombo towononga chakudya chanu.
Pamene sodium benzoate ikuphatikizidwa ndi madzi, benzoic acid imapangidwa.
Benzoic acid ndi mawonekedwe otetezera - mawonekedwe omwe amateteza zakudya. Mankhwala a benzoic amapezedwanso mwachibadwa mu zipatso zina monga cranberries, plums, ndi maapulo.
Bungwe la United States Chakudya ndi Drug Administration laphunzira kwambiri benzoate ya sodium ndipo inapeza kuti ndi yotetezeka pamene idya mu ndalama zomwe zimapezeka mu zakudya zowonongeka. Malingana ndi FDA, zimatengera pafupifupi 180 kuchuluka kwa sodium benzoate yomwe imakhalapo pamadyedwe amodzi asanakhale ndi mavuto ndipo nthawi makumi asanu ndi limodzi (90) kuchuluka kwa sodium benzoate yomwe ingapezeke pa zakudya zomwe zakudya zomwe mumadya zimakhala ndi mankhwala ochuluka kwambiri a sodium benzoate omwe akugwiritsidwa ntchito tsopano. Inde, izo zikumveka zovuta, koma zikutanthawuza kuti zotetezera ndi zotetezeka. Malingana ndi komiti ya FDA Select in General idaona ngati zinthu zotetezedwa s:
Palibe umboni uliwonse umene ulipo kuti asonyeze kuti benzoic acid ndi sodium benzoate monga zakudya zowonjezera zimayambitsa ngozi kwa anthu onse pakagwiritsidwe ntchito pamagulu omwe alipo tsopano kapena omwe angathe kuyembekezera m'tsogolomu.
Koma Nanga Bwanji Zamagulu?
Maina angamveke ngati ofanana, koma benzeni sali ofanana ndi sodium benzoate kapena benzoic asidi, kotero ngati mukudya chinthu chomwe chili ndi sodium benzoate chawonjezeredwa, simukupezeka ku benzene. Ndikofunika kumvetsa zimenezo. Pali tiyi pakati pa benzoic acid ndi benzene zomwe zinayambitsa zakumwa zakumwa zofewa kumayambiriro kwa zaka za 2000.
Kalelo, ena opanga zakumwa zofewa amagwiritsa ntchito sodium benzoate ndi acorbic acid (vitamini C) mwa njira zawo. Mafakitala awiriwa ali otetezeka pansi pa chikhalidwe, koma ndi kutentha kwambiri, akhoza kuthandizana kuti apange benzene. Kuwonetsekera ku zambiri za benzene kumadziwika kuti zimayambitsa khansara.
Popeza kuti mphamvu ya benzeni inalipo, FDA inayesanso zakumwa zakumwa zoziziritsa kukhosi zoposa 200 mu 2005. Ambiri analibe benzene kapena anali ndi magawo ochepera asanu pa biliyoni, omwe amawoneka kuti ali otetezeka kwa anthu.
Ndikofunika kuzindikira kuti kuwonetsa kawirikawiri kumachokera ku mafuta a malasha komanso mafuta, osati zakudya kapena zakumwa - ngakhale sodium benzoate ndi asidi ascorbic kutembenukira ku benzene, magulu omwe amapezeka mu botolo la soda anali ochepa, kotero ogulitsa sanali pangozi . Komabe, opanga zakumwa zoziziritsa kukhosi amasintha zinthu zawo, ndipo mapangidwe a benzeni sichikuvutanso.
Kodi Gwero la Sodium?
Sodium benzoate ndi imodzi mwa zowonjezera zomwe zingakuthandizeni kuti mukhale ndi sodium - chinthu choyenera kuganizira ngati mukuyenera kuyang'ana kuti mukhale ndi sodium. Fufuzani Zolemba Zowona Chakudya kuti mupeze momwe sodium iliri mukutumikira chakudya chomwe mukudya.
