Mukaganizira za titanium dioxide, mungaganizire ngati chinthu chopangira mafuta oteteza dzuwa kapena utoto. Komabe, gulu losunthikali limagwiritsidwanso ntchito m'makampani azakudya, makamaka pazinthu monga odzola ndikutafuna chingamu. Koma kodi titaniyamu dioxide ndi chiyani kwenikweni? Kodi muyenera kuda nkhawa ndi kupezeka kwa titanium dioxide m'zakudya zanu?
Titanium dioxide, yomwe imadziwikanso kutiTiO2, ndi mchere wachilengedwe womwe umagwiritsidwa ntchito ngati choyera komanso chowonjezera pamitundu yosiyanasiyana yazakudya, kuphatikiza chakudya. M’makampani azakudya, titaniyamu woipa amagwiritsidwa ntchito makamaka pofuna kupangitsa kuti zinthu zina monga odzola ndi kutafuna zingaoneke bwino. Zimayamikiridwa chifukwa cha kuthekera kwake kupanga mtundu woyera wonyezimira komanso mawonekedwe osalala, okoma, zomwe zimapangitsa kukhala chisankho chodziwika bwino kwa opanga omwe akuyang'ana kuti apititse patsogolo mawonekedwe azinthu zawo.
Komabe, kugwiritsa ntchitotitaniyamu woipa mu chakudyazadzetsa mikangano ndipo zadzetsa nkhaŵa pakati pa ogula ndi akatswiri a zaumoyo. Chimodzi mwa zifukwa zazikulu ndi chiwopsezo cha thanzi chotenga titanium dioxide nanoparticles, zomwe ndi tinthu ting'onoting'ono ta mankhwala omwe amatha kuyamwa ndi thupi.
Ngakhale chitetezo cha titaniyamu woipa m'zakudya chikadali nkhani yotsutsana, kafukufuku wina amasonyeza kuti kudya titaniyamu woipa wa nanoparticles kungakhale ndi zotsatira zoipa pa thanzi la munthu. Mwachitsanzo, kafukufuku wasonyeza kuti ma nanoparticleswa amatha kuyambitsa kutupa m'matumbo ndikusokoneza mabakiteriya opindulitsa, zomwe zingayambitse vuto la kugaya chakudya ndi zina zaumoyo.
Poyankha madandaulowa, mayiko ena akhazikitsa lamulo loletsa kugwiritsa ntchito titanium dioxide pazakudya. Mwachitsanzo, bungwe la European Union lati titanium dioxide ndi mankhwala ochititsa khansa akakoka mpweya, motero amaletsa kugwiritsidwa ntchito kwake monga chowonjezera cha chakudya. Komabe, chiletsocho sichimakhudza kugwiritsa ntchito titaniyamu woipa muzakudya zomwe zimalowetsedwa, mongaodzolandi kutafuna chingamu.
Ngakhale pali mkangano wozungulira titanium dioxide m'zakudya, ndikofunikira kudziwa kuti chigawochi chimadziwika kuti ndi chotetezeka (GRAS) ndi US Food and Drug Administration (FDA) chikagwiritsidwa ntchito motsatira njira zabwino zopangira. Opanga ayenera kutsatira malangizo okhwima okhudza kugwiritsa ntchito titaniyamu woipa mu chakudya, kuphatikizapo malire pa kuchuluka anawonjezera mankhwala ndi tinthu kukula pawiri.
Ndiye, izi zikutanthauza chiyani kwa ogula? Pomwe chitetezo chatitaniyamu dioxidemu chakudya akadali kuphunzira, m'pofunika kudziwa mankhwala inu kudya ndi kusankha mwanzeru zakudya zanu. Ngati mukuda nkhawa ndi kupezeka kwa titanium dioxide muzakudya zina, ganizirani kusankha zinthu zomwe zilibe zowonjezera izi kapena funsani dokotala kuti akutsogolereni.
Mwachidule, titanium dioxide ndi chinthu chodziwika bwino muzakudya monga ma jellies ndi chingamu, zomwe zimayamikiridwa chifukwa cha kuthekera kwake kukulitsa mawonekedwe ndi mawonekedwe azakudyazi. Komabe, ziwopsezo zomwe zingachitike paumoyo wokhudzana ndi kudya titanium dioxide nanoparticles zadzetsa nkhawa pakati pa ogula ndi akatswiri azaumoyo. Pamene kafukufuku akupitilira pamutuwu, ndikofunikira kuti ogula azikhala odziwa zambiri ndikusankha bwino zakudya zomwe amadya. Kaya mumasankha kupewa zinthu zomwe zili ndi titanium dioxide kapena ayi, kumvetsetsa kupezeka kwa titaniyamu woipa m'zakudya zanu ndi sitepe yoyamba yoyang'anira thanzi lanu ndi thanzi lanu.
