Food-Grade Titanium Dioxide: Katundu, Ntchito, ndi Chitetezo

Chiyambi:

Titanium dioxide (TiO2) ndi mchere wochitika mwachilengedwe womwe wakhala ukugwiritsidwa ntchito kwambiri ngati pigment yoyera m'mafakitale osiyanasiyana chifukwa cha kuwala kwake komanso kuwala kwake.M'zaka zaposachedwapa, titanium dioxide yayambanso kulowa m'makampani azakudya monga chowonjezera cha chakudya, chomwe chimatchedwa titanium dioxide.M'nkhaniyi, tifufuza za katundu, ntchito, malingaliro a chitetezo, ndi machitidwe a titanium dioxide wa chakudya.

Makhalidwe a Food-Grade Titanium Dioxide:

Titanium dioxide wamtundu wa chakudya amagawana katundu wambiri ndi mnzake wamakampani, koma ndi malingaliro apadera achitetezo cha chakudya.Nthawi zambiri imakhala ngati ufa wabwino, woyera ndipo imadziwika ndi index yake yowoneka bwino, yomwe imapangitsa kuti ikhale yowoneka bwino komanso yowala kwambiri.Kukula kwa tinthu ting'onoting'ono kwa titaniyamu woipa wa titaniyamu kumayendetsedwa mosamala kuti kuwonetsetse kuti kubalalitsidwa kofananako komanso kukhudzika kochepa pakupanga kapena kukoma kwazakudya.Kuphatikiza apo, titaniyamu woipa wamtundu wa chakudya nthawi zambiri amayeretsedwa mwamphamvu kuti achotse zonyansa ndi zowononga, ndikuwonetsetsa kuti ndizoyenera kugwiritsidwa ntchito pazakudya.

Njira Zopangira:

Titaniyamu woipa wamtundu wa chakudya amatha kupangidwa pogwiritsa ntchito njira zachilengedwe komanso zopangira.Titaniyamu woipa wachilengedwe umapezeka kuchokera ku mineral deposits, monga rutile ndi ilmenite, kupyolera mu njira monga kuchotsa ndi kuyeretsa.Komano, titaniyamu woipa wopangidwa ndi titaniyamu, amapangidwa kudzera m'machitidwe amankhwala, omwe amakhudza momwe titaniyamu tetrachloride imachitira ndi mpweya kapena sulfure dioxide pa kutentha kwambiri.Mosasamala kanthu za njira yopangira, njira zowongolera zabwino ndizofunikira kuti titanium dioxide ya chakudya ikwaniritse chiyero chokhazikika komanso chitetezo.

Mapulogalamu mu Food Industry:

Titaniyamu woipa wamtundu wa chakudya amagwira ntchito ngati chinthu choyera komanso opacifier muzakudya zambiri.Amagwiritsidwa ntchito kwambiri m'ma confectionery, mkaka, zowotcha, ndi zakudya zina kuti aziwoneka bwino komanso mawonekedwe azakudya.Mwachitsanzo, titaniyamu woipa amawonjezeredwa ku zokutira maswiti kuti apange mitundu yowoneka bwino komanso ku mkaka monga yogati ndi ayisikilimu kuti apangitse kuwala kwawo komanso kununkhira kwake.Muzowotcha, titaniyamu woipa amathandiza kupanga maonekedwe owala, ofanana muzinthu monga chisanu ndi zosakaniza za keke.

Mkhalidwe Wowongolera ndi Chitetezo:

Kutetezedwa kwa titaniyamu woipa wamtundu wa chakudya ndi nkhani yomwe ikukambidwa mosalekeza komanso kuunika koyang'anira.Mabungwe olamulira padziko lonse lapansi, kuphatikiza Food and Drug Administration (FDA) ku United States ndi European Food Safety Authority (EFSA) ku Europe, awunika chitetezo cha titanium dioxide ngati chowonjezera chakudya.Ngakhale titanium dioxide nthawi zambiri imadziwika kuti ndi yotetezeka (GRAS) ikagwiritsidwa ntchito m'malire otchulidwa, nkhawa zakhala zikukhudzidwa ndi kuopsa kwa thanzi lomwe lingakhalepo chifukwa chakumwa kwake, makamaka mu mawonekedwe a nanoparticle.

Zomwe Zingachitike Paumoyo Wanu:

Kafukufuku wasonyeza kuti titanium dioxide nanoparticles, yomwe ndi yaying'ono kuposa 100 nanometers mu kukula, ikhoza kukhala ndi mwayi wolowera zotchinga zamoyo ndi kudziunjikira mu minofu, kudzutsa nkhawa za chitetezo chawo.Kafukufuku wa zinyama awonetsa kuti mlingo waukulu wa titanium dioxide nanoparticles ungayambitse chiwindi, impso, ndi ziwalo zina.Kuphatikiza apo, pali umboni wosonyeza kuti titaniyamu woipa nanoparticles angayambitse kupsinjika kwa okosijeni ndi kutupa m'maselo, zomwe zingapangitse kukula kwa matenda osatha.

Njira Zochepetsera ndi Njira Zina:

Pofuna kuthana ndi nkhawa zokhudzana ndi chitetezo cha titanium dioxide wamtundu wa chakudya, kuyesetsa kupanga njira zina zoyeretsera zoyera ndi zowunikira zomwe zingathe kukwaniritsa zotsatira zofanana popanda kuopsa kwa thanzi.Opanga ena akufufuza njira zina zachilengedwe, monga calcium carbonate ndi rice starch, m'malo mwa titanium dioxide muzakudya zina.Kuphatikiza apo, kupita patsogolo kwa nanotechnology ndi uinjiniya wa tinthu kungapereke mwayi wochepetsera kuopsa kokhudzana ndi titanium dioxide nanoparticles kudzera mukupanga tinthu tating'ono komanso kusinthidwa kwapamwamba.

Kudziwitsa Anthu ndi Malembo:

Kulemba mosabisa mawu komanso kuphunzitsa ogula ndikofunikira pakudziwitsa ogula za kupezeka kwa zakudya monga titanium dioxide muzakudya.Zolemba zomveka bwino komanso zolondola zitha kuthandiza ogula kusankha mwanzeru ndikupewa zinthu zomwe zili ndi zowonjezera zomwe zingawakhumudwitse kapena kuwadetsa nkhawa.Kuphatikiza apo, kuzindikira kochulukira kwa zowonjezera zakudya ndi zomwe zingakhudze thanzi lawo zitha kupatsa mphamvu ogula kulimbikitsa njira zoperekera zakudya zotetezeka komanso zowonekera bwino.

Tsogolo la Outlook ndi Malangizo Ofufuza:

Tsogolo la titaniyamu wopatsa mphamvu wa chakudya limatengera khama lomwe likuchitika pofufuza kuti amvetsetse bwino zachitetezo chake komanso zotsatira zake paumoyo.Kupita patsogolo kwa nanotoxicology, kuunika kwachidziwitso, komanso kuunika kwachiwopsezo kudzakhala kofunika kwambiri pakudziwitsa anthu kupanga zisankho ndikuwonetsetsa kuti titaniyamu woipa wa titaniyamu amagwiritsidwa ntchito moyenera popanga chakudya.Kuphatikiza apo, kafukufuku wokhudzana ndi njira zina zoyeretsera zoyera ndi ma opacifiers ali ndi chiyembekezo chothana ndi zovuta za ogula ndikuyendetsa zatsopano m'makampani azakudya.

Pomaliza:

Titaniyamu woipa wamtundu wa chakudya amagwira ntchito yofunika kwambiri m'makampani azakudya ngati chinthu choyera komanso chosawoneka bwino, kumapangitsa kuti zakudya zamitundumitundu ziziwoneka bwino.Komabe, nkhawa zokhudzana ndi chitetezo chake, makamaka mu mawonekedwe a nanoparticle, zapangitsa kuunika koyang'anira ndikufufuza mosalekeza.Pamene tikupitiriza kufufuza za chitetezo ndi mphamvu ya titanium dioxide ya chakudya, ndikofunikira kuika patsogolo chitetezo cha ogula, kuwonekera, ndi luso lazogulitsa zakudya.
