Iyo utekereje kuri dioxyde ya titanium, urashobora kuyishushanya nkibigize ibara ryizuba cyangwa irangi. Nyamara, iyi mvange itandukanye ikoreshwa no mubikorwa byibiribwa, cyane cyane mubicuruzwa nka jelly naguhekenya. Ariko dioxyde ya titanium ni iki? Wakagombye guhangayikishwa no kubona dioxyde ya titanium mu biryo byawe?
Dioxyde ya Titanium, izwi kandi nkaTiO2, ni imyunyu ngugu isanzwe ikoreshwa nkibintu byera kandi byongera amabara mubicuruzwa bitandukanye byabaguzi, harimo ibiryo. Mu nganda zibiribwa, dioxyde de titanium ikoreshwa cyane cyane mukuzamura isura nuburyo bwibicuruzwa bimwe na bimwe, nka jelly na chewine. Ihabwa agaciro kubushobozi bwayo bwo gukora ibara ryera ryera kandi ryoroshye, ryuzuye amavuta, bigatuma ihitamo gukundwa nababikora bashaka kureba neza ibicuruzwa byabo byibiribwa.
Ariko, ikoreshwa ryadioxyde ya titanium mu biryobyakuruye impaka kandi bitera impungenge mubaguzi ninzobere mubuzima. Imwe mumpamvu nyamukuru ningaruka zishobora gutera ubuzima bwo gufata titanium dioxide nanoparticles, ni uduce duto duto twimiti ishobora kwinjizwa numubiri.
Mu gihe umutekano wa dioxyde de titanium mu biribwa ukomeje kuba impaka, ubushakashatsi bumwe bwerekana ko kunywa titanium dioxyde de nanoparticles bishobora kugira ingaruka mbi ku buzima bw’abantu. Kurugero, ubushakashatsi bwerekanye ko nanoparticles ishobora gutera amara no guhungabanya uburinganire bwa bagiteri zifite akamaro, zishobora gutera ibibazo byigifu nibindi bibazo byubuzima.
Mu rwego rwo gukemura ibyo bibazo, ibihugu bimwe byashyize mu bikorwa amategeko abuza ikoreshwa rya dioxyde ya titanium mu biribwa. Kurugero, Umuryango w’ubumwe bw’ibihugu by’i Burayi washyize mu majwi dioxyde ya titanium nka kanseri ishobora gutera iyo ihumeka, bityo ikabuza kuyikoresha nk'inyongeramusaruro. Ariko, kubuzwa ntibikoreshwa mugukoresha dioxyde ya titanium mubiribwa byinjiye, nkajellyguhekenya amenyo.
N’ubwo impaka zishingiye kuri dioxyde de titanium mu biribwa, birakwiye ko tumenya ko muri rusange uruganda ruzwi nk’umutekano (GRAS) n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) iyo rukoreshejwe hakurikijwe uburyo bwiza bwo gukora. Ababikora bagomba kubahiriza amabwiriza akomeye yerekeranye no gukoresha dioxyde ya titanium mu biryo, harimo imipaka ku mubare wongeyeho ibicuruzwa n’ubunini bw’ibicuruzwa.
None, ibi bivuze iki kubakoresha? Mugihe umutekano wadioxyde de titaniummubiryo biracyigwa, ni ngombwa kumenya ibicuruzwa ukoresha kandi ugahitamo ubwenge kubijyanye nimirire yawe. Niba uhangayikishijwe no kuba hari dioxyde de titanium mu biribwa bimwe na bimwe, tekereza guhitamo ibicuruzwa bitarimo iyi nyongeramusaruro cyangwa ubaze inzobere mu by'ubuzima kugira ngo ikuyobore.
Muri make, dioxyde ya titanium nikintu gikunze kuboneka mubiribwa nka jellies na chewine, bihabwa agaciro kubushobozi bwacyo bwo kuzamura isura nuburyo bwibiryo. Nubwo bimeze bityo ariko, ingaruka z’ubuzima ziterwa no kunywa titanium dioxyde de nanoparticles yateje impungenge abakiriya n’inzobere mu buzima. Mugihe ubushakashatsi bukomeje kuriyi nsanganyamatsiko, ni ngombwa ko abaguzi bakomeza kumenyeshwa no gufata ibyemezo bijyanye nibiryo barya. Waba wahisemo kwirinda ibicuruzwa birimo dioxyde ya titanium cyangwa utabikora, gusobanukirwa ko dioxyde de titanium iri mu biryo byawe nintambwe yambere yo kugenzura ubuzima bwawe n'imibereho myiza.
