Chikafu-Giredhi Titanium Dioxide: Zvivakwa, Zvishandiso, uye Chengetedzo Kufunga

Nhanganyaya:

Titanium dioxide (TiO2) iminerari inongoitika yechisikigo yakashandiswa zvakanyanya sepigment chena mumaindasitiri akasiyana siyana ekuvheneka kwayo nekupenya kwayo. Mumakore achangopfuura, titanium dioxide yakawanawo nzira yayo kupinda muindasitiri yezvekudya sechinhu chinowedzera chikafu, chinozivikanwa sefood-grade titanium dioxide. Muchinyorwa ichi, tichaongorora zvivakwa, mashandisirwo, kufunga nezvekuchengetedza, uye zvimiro zvechikafu-giredhi titanium dioxide.

Zvimiro zveChikafu-Giredhi Titanium Dioxide:

Chikafu-giredhi titanium dioxide inogovera akawanda zvivakwa pamwe neayo maindasitiri, asi ine tarisiro chaiyo yekuchengetedza chikafu. Iyo inowanzovapo muchimiro chehupfu, chena uye inozivikanwa neiyo yakakwira refractive index, iyo inopa kupenya kwakanyanya uye kupenya. Saizi yechikamu chechikafu-giredhi titanium dioxide inodzorwa nekuchenjera kuti ive nechokwadi chekupararira kwakafanana uye kushomeka kunokanganisa magadzirirwo kana kuravira muzvigadzirwa zvekudya. Pamusoro pezvo, chikafu-giredhi titanium dioxide inowanzoiswa kune yakasimba yekucheneswa maitiro ekubvisa tsvina uye zvinosvibisa, kuve nechokwadi kuti yakakodzera kushandiswa mukushandisa kwechikafu.

Nzira dzekugadzira:

Chikafu-giredhi titanium dioxide inogona kugadzirwa uchishandisa ese ari maviri echisikigo uye ekugadzira nzira. Natural titanium dioxide inowanikwa kubva mumamineral deposits, senge rutile uye ilmenite, kuburikidza nematanho akaita sekubvisa uye kucheneswa. Synthetic titanium dioxide, kune rumwe rutivi, inogadzirwa kuburikidza nemakemikari maitiro, anowanzo sanganisira kuita kwetitanium tetrachloride neokisijeni kana sulfur dioxide pakupisa kwakanyanya. Kunyangwe iyo nzira yekugadzira, matanho ekudzora emhando akakosha kuve nechokwadi chekuti chikafu-giredhi titanium dioxide inosangana nekuchena kwakasimba uye kuchengetedza zviyero.

Zvishandiso muIndasitiri Yezvekudya:

Chikafu-giredhi titanium dioxide inoshanda zvakanyanya seyakachena mumiriri uye opacifier mune dzakasiyana siyana zvigadzirwa zvekudya. Inowanzo shandiswa mune confectionery, dairy, zvakabikwa, uye mamwe mapoka echikafu kuwedzera kukwezva kwekuona uye kuumbwa kwezvinhu zvekudya. Semuenzaniso, titanium dioxide inowedzerwa kune zvihwitsi zvekupfeka kuti zviwane mavara ane simba uye kune zvigadzirwa zvemukaka seyogati neaizikirimu kuti vavandudze kupenya kwavo uye kuchena. Muzvinhu zvakabikwa, titanium dioxide inobatsira kugadzira kujeka, kutaridzika kweyunifomu muzvigadzirwa zvakaita sechando nemisanganiswa yekeke.

Regulatory Status uye Chengetedzo Yekufunga:

Kuchengetedzwa kwechikafu-giredhi titanium dioxide inyaya yegakava rinoramba riripo uye kuongororwa kwemitemo. Masangano anodzora pasi rese, anosanganisira Food and Drug Administration (FDA) muUnited States neEuropean Food Safety Authority (EFSA) muEurope, vakaongorora kuchengetedzeka kwetitanium dioxide sekuwedzera kwechikafu. Nepo titanium dioxide ichiwanzo zivikanwa seyakachengeteka (GRAS) kana ichishandiswa mukati memiganhu yakatarwa, zvinonetsa zvakasimudzwa pamusoro penjodzi dzinogona kuitika dzehutano dzine chekuita nekushandiswa kwayo, kunyanya mune nanoparticle form.

Zvinogona Kukonzera Utano:

Zvidzidzo zvakaratidza kuti titanium dioxide nanoparticles, idiki pane 100 nanometers muhukuru, inogona kunge iine mukana wekupinda mubiological zvipingamupinyi uye kuungana mumatissue, zvichimutsa kunetseka nezve kuchengeteka kwavo. Zvidzidzo zvemhuka zvakaratidza kuti madhasi akakwira etitanium dioxide nanoparticles anogona kukonzera mhedzisiro pachiropa, itsvo, uye dzimwe nhengo. Uyezve, pane humbowo hunoratidza kuti titanium dioxide nanoparticles inogona kukonzera oxidative kusagadzikana uye kuzvimba mumaseru, zvichikonzera kukura kwezvirwere zvisingaperi.

Maitiro ekuderedza uye dzimwe nzira:

Kugadzirisa zvinonetsa nezve kuchengetedzeka kwechikafu-giredhi titanium dioxide, kuyedza kuri kuenderera mberi kugadzira mamwe maajenti ekuchena uye maopacifiers anogona kuzadzisa zvakafanana pasina njodzi dzinogona kuitika pahutano. Vamwe vagadziri vari kutsvaga dzimwe nzira dzechisikigo, dzakadai se calcium carbonate uye mupunga starch, sekutsiva titanium dioxide mune zvimwe zvekudya. Pamusoro pezvo, kufambira mberi mune nanotechnology uye particle engineering inogona kupa mikana yekudzikamisa njodzi dzine chekuita netitanium dioxide nanoparticles kuburikidza nekuvandudza chidimbu dhizaini uye kugadziridzwa kwepasi.

Kuzivisa Kwevatengi uye Kuisa Mazita:

Kunyora kwakajeka uye kudzidzisa kwevatengi kwakakosha pakuzivisa vatengi nezve kuvapo kwezvinowedzera zvekudya senge titanium dioxide muzvigadzirwa zvekudya. Kunyora kwakajeka uye kwakaringana kunogona kubatsira vatengi kuita sarudzo dzine ruzivo uye kudzivirira zvigadzirwa zvine zvekuwedzera izvo zvavangave nekunzwa kana kunetseka nazvo. Zvakare, kuwedzera kuziva kwezvekuwedzera kwechikafu uye zvazvingaite pahutano zvinogona kupa vatengi simba rekureverera kune yakachengeteka uye yakajeka macheni ekupa chikafu.

Ramangwana Outlook uye Tsananguro dzekutsvagisa:

Remangwana rechikafu-giredhi titanium dioxide rinotsamira pakuedza kuri kuramba kuchienderera mberi kwekutsvagisa kuti unzwisise zviri nani chimiro chayo chekuchengetedza uye mhedzisiro yehutano. Kuenderera mberi kufambira mberi mune nanotoxicology, kuongororwa kwenjodzi, uye kuongororwa kwenjodzi kuchave kwakakosha pakuzivisa hurongwa hwekuita sarudzo uye kuona kushandiswa kwakachengeteka kwetitanium dioxide mukushandisa chikafu. Pamusoro pezvo, kutsvagisa kune mamwe maajenti ekuchena uye opacifiers ane vimbiso yekugadzirisa zvinonetsa mutengi uye kutyaira hunyanzvi muindasitiri yechikafu.

Mhedziso:

Chikafu-giredhi titanium dioxide inoita basa rakakosha muindasitiri yechikafu sechinhu chinochenesa uye opacifier, ichiwedzera kukwezva kwekuona uye magadzirirwo emhando dzakasiyana dzezvigadzirwa zvekudya. Nekudaro, kushushikana nezve kuchengetedzeka kwayo, kunyanya mune nanoparticle fomu, kwakurudzira kuongororwa kwemitemo uye kuenderera mberi kwekutsvaga. Sezvo isu tichienderera mberi nekuongorora kuchengetedzeka uye kushanda kwechikafu-giredhi titanium dioxide, zvakakosha kuti titarise kuchengetedzeka kwevatengi, kujeka, uye hunyanzvi mumaketani ekupa chikafu.
