Mumakore achangopfuura, titanium dioxide yave nyaya inopisa munhaurirano nezvekuchengetedza kwechikafu uye kubuda pachena. Sezvo vatengi vachiwedzera kuziva zviri muchikafu chavo, kuvepo kwetitanium dioxide kuri kukonzera kunetseka. Nhau idzi dzine chinangwa chekujekesa nezvekuchengetedza, kushandiswa, uye kukakavara kwakatenderedza komboni iyi uku ichiratidzira basa revatungamiriri veindasitiri vakaita seCoolway mukugadzira yemhando yepamusoro titanium dioxide.
Chii chinonzi titanium dioxide?
Titanium dioxide TiO2chicherwa chechisikigo chinoshandiswa zvakanyanya mumaindasitiri akasiyana sechikafu, zvizorwa uye pendi. Muindasitiri yechikafu, inonyanya kushandiswa seyakachena mumiriri uye inowanzowanikwa mune zvigadzirwa zvakaita senge confectionery, zvakabikwa, uye zvigadzirwa zvemukaka. Kugona kwayo kuwedzera kukwezva kwechikafu kwezvigadzirwa kunoita kuti ive sarudzo yakakurumbira pakati pevagadziri.
Chekuchengetedza Mubvunzo
Kuchengeteka kwetitanium dioxide muchikafu kwave kuchinetsa. Masangano anodzora akadai seUS Food and Drug Administration (FDA) neEuropean Food Safety Authority (EFSA) anoona kuti titanium dioxide yakachengeteka kana ikadyiwa mushoma. Nekudaro, zvidzidzo zvenguva pfupi yapfuura zvakasimudza kushushikana pamusoro penjodzi dzayo dzehutano, kunyanya kana dzakapinzwa mune nanoparticle fomu. Vamwe vaongorori vanotenda kuti nanoparticles idzi dzinogona kuungana mumuviri uye kukonzera hutano husina kunaka.
Pasinei nezvinetso izvi, vagadziri vezvokudya vakawanda vanoramba vachidarokushandisa titanium dioxide, ichidudza kushanda kwayo uye kushaikwa kweuchapupu hwakasimba hunoibatanidza nezvinetso zvakakomba zvoutano. Nekuda kweizvozvo, vatengi vanofanirwa kufambisa ruzivo rwakaoma uye maonero.
Shandisa muindasitiri yezvekudya
Titanium dioxide inopfuura kungowedzera zvokudya; ine akawanda maapplication munzvimbo dzakasiyana. Muindasitiri yezvekudya inonyanya kushandiswa kuchena kwayo asi inoshandiswawo seyakagadzikana uye anti-caking agent. Mukuwedzera kune zvokudya, titanium dioxide inokosha mukugadzirwa kwepende, machira uye mapurasitiki, uko inopa opacity uye kupenya.
Yakakosha fomu yetitanium dioxide ikemikari fiber giredhi titanium dioxide yakagadziridzwa uchishandisa advanced kugadzirwa tekinoroji. Makambani akaita saKewei akapayona maitiro aya, achive nechokwadi chekuti zvigadzirwa zvawo zvinosangana nezvinodiwa zvevagadziri vemakemikari emumba. Nezvigadzirwa zvemazuva ano zvekugadzira uye kuzvipira kuhutano, Kewei ave mutungamiri wemabhizimisi, kunyanya mukugadzirwa kwetitanium dioxide sulfate.
Kukakavadzana uye Kuziva Kwevatengi
Kukakavadzana kwakapoteredzatitanium dioxidekazhinji kunobva pakurongwa kwayo sechikafu chekuwedzera. Kunyange vamwe vachitenda kuti inovandudza kunaka kwekudya, vamwe vanotenda kuti kushandiswa kwayo kunofanirwa kudzikiswa kana kubviswa zvachose. Kukura kwemaitiro ekudya kwakachena uye zvimiro zvechisikigo zvaita kuti vatengi vazhinji vatsvage dzimwe nzira dzekuwedzera, zvichiita kuti vagadziri vezvekudya vafunge zvakare zvinyorwa zvavo zvemukati.
Sezvo vatengi vanova neruzivo rwakawanda, ndizvo zvinoitawo zvinoda kubuda pachena mumalebhu echikafu. Vakawanda vanotsigira mitemo yakajeka pamusoro pekushandiswa kwetitanium dioxide nezvimwe zvinowedzera, vachisundira kutsvakurudza kwakawanda kuti vanzwisise maitiro avo ehutano kwenguva refu.
mukupedzisa
Chokwadi nezvetitanium dioxide muzvokudyayakaoma, kusanganisira kuchengetedzwa kwayo, kushandiswa uye kukakavara kunoenderera. Nepo maregulator achizviona zvakachengeteka kudyiwa, kuwedzera kwekuziva kwevatengi uye kudiwa kwekubuda pachena kuri kumutsa nhaurirano dzakakosha nezve basa rayo mukugovera kwedu chikafu. Makambani akaita seCowe ari pamberi pehurukuro iyi, achigadzira yemhando yepamusoro titanium dioxide asi achiisa pamberi pekuchengetedzwa kwezvakatipoteredza uye kuvimbika kwechigadzirwa. Sezvo isu tichifamba nemamiriro ezvinhu aya ari kusimukira, vatengi vanofanirwa kugara vaine ruzivo uye kuita sarudzo dzinoenderana nehunhu hwavo uye zvinetswa zvehutano.
