Ibiryo-Urwego rwa Titanium Dioxyde: Ibyiza, Porogaramu, hamwe nibitekerezo byumutekano

Iriburiro:

Dioxyde ya Titanium (TiO2) ni imyunyu ngugu isanzwe ibaho yakoreshejwe cyane nka pigment yera mubikorwa bitandukanye byinganda kugirango ibe nziza kandi nziza.Mu myaka yashize, dioxyde de titanium nayo yabonye inzira mu nganda z’ibiribwa nk'inyongeramusaruro, izwi ku izina rya dioxyde de titanium.Muri iyi nyandiko, tuzasesengura imiterere, ibisabwa, gutekereza ku mutekano, hamwe n’amabwiriza agenga ibiryo byo mu rwego rwa titanium dioxyde.

Ibyiza byibiryo-Urwego rwa Titanium Dioxyde:

Dioxyde de titanium yo mu rwego rwo hejuru isangira ibintu byinshi na mugenzi wayo mu nganda, ariko hamwe nibitekerezo byihariye byo kwihaza mu biribwa.Mubisanzwe ibaho muburyo bwa poro nziza, yera kandi izwiho indangagaciro yo hejuru cyane, itanga ububobere bwiza nubucyo.Ingano yubunini bwibiryo byo mu rwego rwa titanium dioxyde igenzurwa neza kugirango habeho gutatanya kimwe ningaruka nkeya kumiterere cyangwa uburyohe mubicuruzwa byibiribwa.Byongeye kandi, dioxyde de titanium yo mu rwego rwo hejuru ikunze gukorerwa uburyo bukomeye bwo kweza kugirango ikureho umwanda n’ibyanduye, byemeze ko bikoreshwa mu gukoresha ibiryo.

Uburyo bwo gukora:

Dioxyde de vitamine yo mu rwego rwo hejuru irashobora kubyazwa umusaruro hakoreshejwe uburyo karemano nubukorikori.Dioxyde de titanium isanzwe iboneka mumabuye y'agaciro, nka rutile na ilmenite, binyuze mubikorwa nko gukuramo no kweza.Ku rundi ruhande, dioxyde de sintetike ya sintetike, ikorwa hifashishijwe uburyo bwa shimi, ubusanzwe burimo reaction ya titanium tetrachloride hamwe na ogisijeni cyangwa dioxyde de sulfure ku bushyuhe bwinshi.Hatitawe ku buryo bwo kubyaza umusaruro, ingamba zo kugenzura ubuziranenge ni ngombwa kugira ngo dioxyde de titanium yo mu rwego rw’ibiribwa yujuje ubuziranenge bukomeye n’umutekano.

Ibisabwa mu nganda zibiribwa:

Dioxyde de titanium yo mu rwego rwo hejuru ikora cyane cyane nk'umuzungu no kwera mu bicuruzwa byinshi byibiribwa.Bikunze gukoreshwa mubirungo, amata, ibicuruzwa bitetse, nibindi byiciro byibiribwa kugirango byongere ubwiza bwibintu hamwe nibiribwa.Kurugero, dioxyde ya titanium yongewe kumyenda ya bombo kugirango igere kumabara meza ndetse no mubikomoka ku mata nka yogurt na ice cream kugirango bitezimbere ububobere bwabo.Mu bicuruzwa bitetse, dioxyde ya titanium ifasha gukora isura nziza, imwe mubicuruzwa nko gukonjesha no kuvanga cake.

Imiterere igenga n'ibitekerezo byumutekano:

Umutekano wa dioxyde de titanium yo mu rwego rwo hejuru ni ingingo ikomeje kugibwaho impaka no kugenzura.Inzego zishinzwe kugenzura isi ku isi, harimo n’ubuyobozi bushinzwe ibiryo n’ibiyobyabwenge (FDA) muri Amerika ndetse n’ikigo cy’Uburayi gishinzwe umutekano w’ibiribwa (EFSA) mu Burayi, basuzumye umutekano wa dioxyde de titanium nk'inyongeramusaruro.Mu gihe dioxyde ya titanium isanzwe izwi nk’umutekano (GRAS) iyo ikoreshejwe mu gihe cyagenwe, hagaragaye impungenge z’ingaruka z’ubuzima zishobora guterwa no kuyikoresha, cyane cyane mu buryo bwa nanoparticle.

Ingaruka zishobora kubaho ku buzima:

Ubushakashatsi bwagaragaje ko nanoparticles ya titanium dioxyde, iri munsi ya nanometero 100 mu bunini, ishobora kuba ifite ubushobozi bwo kwinjira mu nzitizi z’ibinyabuzima no kwirundanyiriza mu ngingo, bigatuma impungenge z’umutekano wabo.Ubushakashatsi bw’inyamaswa bwerekanye ko urugero rwinshi rwa titanium dioxyde de nanoparticles rushobora gutera ingaruka mbi ku mwijima, impyiko, n’izindi ngingo.Byongeye kandi, hari ibimenyetso byerekana ko titanium dioxyde de nanoparticles ishobora gutera okiside itera no gutwika mu ngirabuzimafatizo, bikaba byagira uruhare mu iterambere ry’indwara zidakira.

Ingamba zo Kugabanya Ubundi buryo:

Kugira ngo hakemurwe impungenge z’umutekano wa dioxyde de titanium yo mu rwego rw’ibiribwa, hakomeje gukorwa ingamba zo guteza imbere ubundi buryo bwo kwera hamwe na opacifiers zishobora kugera ku ngaruka nkizo nta ngaruka z’ubuzima zishobora kubaho.Bamwe mu bakora inganda barimo gushakisha ubundi buryo busanzwe, nka calcium karubone na krahisi yumuceri, nkibisimbuza dioxyde ya titanium mubiribwa bimwe na bimwe.Byongeye kandi, iterambere muri nanotehnologiya hamwe nubwubatsi bwa tekinike birashobora gutanga amahirwe yo kugabanya ingaruka ziterwa na titanium dioxyde de nanoparticles binyuze muburyo bunoze bwo gushushanya no guhindura ubuso.

Kumenya abaguzi no kuranga:

Kwandika neza no kwigisha abaguzi ni ngombwa mu kumenyesha abakiriya ko hari inyongeramusaruro y'ibiribwa nka dioxyde ya titanium mu bicuruzwa.Ibimenyetso bisobanutse kandi byukuri birashobora gufasha abakiriya guhitamo neza no kwirinda ibicuruzwa birimo inyongeramusaruro bashobora kuba bafite sensitivité cyangwa impungenge.Byongeye kandi, kongera ubumenyi bw’inyongeramusaruro n’ingaruka zishobora kugira ku buzima birashobora guha imbaraga abakiriya kunganira urunigi rw’ibiribwa rwizewe kandi rweruye.

Icyerekezo kizaza hamwe nubuyobozi bwubushakashatsi:

Ejo hazaza h'ibiryo byo mu rwego rwa titanium dioxyde ishingiye ku bikorwa bigamije ubushakashatsi kugira ngo dusobanukirwe neza imiterere y’umutekano n'ingaruka z’ubuzima.Iterambere rikomeje muri nanotoxicologie, gusuzuma imurikagurisha, no gusuzuma ingaruka bizaba ingenzi mu kumenyesha ibyemezo bifata ibyemezo no kwemeza ikoreshwa rya dioxyde de titanium mu gukoresha ibiryo.Byongeye kandi, ubushakashatsi bwibindi bikoresho byera hamwe na opacifiers bitanga amasezerano yo gukemura ibibazo by’abaguzi no guteza imbere udushya mu nganda z’ibiribwa.

Umwanzuro:

Dioxyde de titanium yo mu rwego rwo hejuru igira uruhare runini mu nganda z’ibiribwa nkumukozi wera na opacifier, byongera ubwiza bwibonekeje hamwe nuburyo butandukanye bwibicuruzwa byibiribwa.Nyamara, impungenge z'umutekano wacyo, cyane cyane muburyo bwa nanoparticle, zatumye hasuzumwa amabwiriza hamwe nubushakashatsi bukomeje.Mugihe dukomeje gushakisha umutekano ningirakamaro bya dioxyde de titanium yo mu rwego rwo hejuru, ni ngombwa gushyira imbere umutekano w’abaguzi, gukorera mu mucyo, no guhanga udushya mu gutanga ibiribwa.
