Tepi ya PTFE Yokhudzana ndi Chakudya: Kutentha & Kutalika Kwanthawi Zomwe Muyenera Kudziwa

Ngati mumagwiritsa ntchito chosindikizira kutentha popaka chakudya, sungani thireyi yophikira, kapena phimbani lamba wotumizira chakudya. Tepi ya PTFE yotentha kwambiri , muyenera kudziwa: imatha kutentha bwanji? Kwa nthawi yayitali bwanji? Ndipo zimakhala zosatetezeka liti?

PTFE imadziwika ndi kukana kutentha kwambiri, koma 'kusamva kutentha' sikutanthauza 'zopanda malire'. Kupitilira malire a kutentha kungayambitse kuwonongeka kwa zinthu - ndipo zikavuta kwambiri, kutulutsa utsi wapoizoni womwe suyenera kukhudzana ndi chakudya.

Aokai PTFE yapereka matepi amtundu wa PTFE wazaka zambiri. Bukuli likufotokoza za madera otetezeka a kutentha, malire a nthawi, ndi zofunikira zoyendetsera (FDA, EU) pazakudya.

Malire a Kutentha - Magawo Atatu Ovuta

Aokai PTFE imapanga tepi ya zakudya zoyesedwa kuti zipirire 260 ° C mosalekeza. Timalangiza makasitomala omwe ali ndi malire (mwachitsanzo, 270-280 ° C intermittent) kuti apange mapu a kutentha pamwamba pa malo ndi kulingalira kalasi ya tepi yowonjezereka, yomwe imapereka kutentha kwambiri komanso kuchepa pang'onopang'ono.

Malire a Nthawi - Kodi 'Safe' Ndi Nthawi Yaitali Bwanji?

Pakadali pano, malamulo akuluakulu achitetezo apadziko lonse lapansi kuphatikiza FDA 21 CFR 177.1550 (USA) ndi EU Regulation No 10/2011 sananene nthawi yolumikizana yotetezeka ya matepi a PTFE. Malire a nthawi amatsimikiziridwa ndi kutentha kwa ntchito.

Zitsanzo zothandiza:

• Kuphika mkate pa 200 ° C kwa mphindi 30 - otetezeka kwathunthu, kugwiritsidwa ntchito mobwerezabwereza kwa miyezi kuli bwino.

• Kutenthetsa kusindikiza matumba a polyethylene pa 180 ° C kwa 1 sekondi - otetezeka, mamiliyoni ambiri ozungulira.

• Kuyeretsa chosindikizira kutentha pothamanga pa 280 ° C kwa mphindi 10 - zovomerezeka nthawi zina, koma osati tsiku lililonse.

• Kugwiritsa ntchito tepi ya PTFE ngati chowotcha pa 300 ° C kwa maola 2 - osatetezeka; tepi idzawononga.

Kutsata Malamulo - FDA & Miyezo ya EU

FDA 21 CFR 177.1550 - Lamuloli limakhudza utomoni wa PTFE wobwereza kukhudzana ndi chakudya. Sichimatchula nthawi yeniyeni koma imafuna kuti nkhani yomalizidwa (tepiyo) ipangidwe mogwirizana ndi Good Manufacturing Practices (GMP) ndipo sayenera kuchititsa kuti chakudya chiipitsidwe.

EU Regulation 10/2011 - Lamuloli limakhudza zinthu zapulasitiki zomwe zimafuna kukumana ndi chakudya. PTFE yalembedwa ngati chinthu chovomerezeka. Malire akusamuka onse amagwira ntchito (nthawi zambiri ≤10 mg/dm²).

Momwe kutsatiridwa kumatsimikizidwira: Kutsatira kumasiyana malinga ndi momwe kumvera kumayendera ndipo kuyenera kutsimikiziridwa ndi mayeso osamukira . Mayesero oterowo amapangidwa potengera kusakanikirana koopsa kwambiri kwa kutentha ndi nthawi yolumikizana m'malo enieni ogwira ntchito.

Malangizo Othandiza Pamapulogalamu Okhudzana ndi Chakudya

Zoyenera kuchita:

• ✓ Gwiritsani ntchito tepi ya PTFE mkati mwa 260°C mosalekeza pophika, kusindikiza, ndi kutumiza

• ✓ Pakuyeretsa kwakanthawi kochepa pa 280-300 ° C , chepetsani nthawi mpaka mphindi 5-10 ndikulola kuziziritsa.

• ✓ Bwezerani tepi pamene pamwamba pakhala khwimbi, kusinthika, kapena kusagwira ntchito kwatsika

• ✓ Sungani tepi pamalo aukhondo, owuma malinga ndi momwe wopanga amafotokozera

Osachita:

• ✗ Osapitirira 327 ° C - PTFE imawola ndikutulutsa utsi wapoizoni

• ✗ Osayika moto wolunjika pa tepi ya PTFE

• ✗ Osagwiritsa ntchito tepi ya PTFE yopitilira 260 ° C polumikizana ndi chakudya nthawi yayitali (mwachitsanzo, kuphika tsiku lonse pa 270 ° C)

• ✗ Musanyalanyaze zizindikiro za ukalamba - kukhala wachikasu, kuphulika, kapena ming'alu ya pamwamba

Mukakayikira: Yesani kuyesa kusamuka pa kutentha kwanu koipitsitsa komanso nthawi yayitali, kapena funsani wopanga matepi kuti mudziwe zambiri za pulogalamuyo.

Mwachidule , tepi ya PTFE yotentha kwambiri imakhala yotetezeka kukhudzana ndi chakudya ikagwiritsidwa ntchito mkati mwa malire ake: ≤260 ° C kuti mugwiritse ntchito mosalekeza, ≤300 ° C pamapiri aafupi (mphindi zokha) , ndipo osapitirira 327 ° C . Malamulo a FDA ndi EU samayika malire anthawi zonse - nthawi yolumikizana yotetezeka imadalira kutentha ndipo iyenera kutsimikiziridwa ndi mayeso osamukira kutengera momwe zinthu ziliri.

Pazakudya zodziwika bwino - kuphika, kusindikiza kutentha, ndi zomangira zopanda ndodo - tepi ya PTFE ili bwino mkati mwa magawo otetezeka. Koma nthawi zonse muziyezera kutentha kwenikweni, sinthani tepi yokalamba mwachangu, ndipo fufuzani zolembedwa zamalamulo kuti zigwiritsidwe ntchito.

Mukufuna tepi ya PTFE ya chakudya cha kutentha komanso nthawi yayitali? Aokai PTFE imapereka matepi ogwirizana ndi FDA okhala ndi magawo otetezedwa olembedwa. Lumikizanani nafe kuti mupeze mapepala aukadaulo komanso thandizo loyesa kusamuka.
