I-PFOA ne-PTFE Cookware - Mayelana Nempilo Yakho

Inkulumo-mpikiswano mayelana ne-nonstick cookware ayiphikisani nokutholakala kwayo kalula noma ukusebenziseka kalula.Iyazikhathaza ngokuthi izinhlanganisela ezimbili: PFOA ne-PTFE ziphephile yini, ikakhulukazi uma zisetshenziswa njengendawo yokupheka.Kunezimpendulo eziningi kule nkinga, kuye ngokuthi kucatshangelwa kabanzi kangakanani umonakalo ongaba khona walezi zinto.

Abanye abapheki bakhathazeke ngokuyinhloko ngemiphumela emibi engaba khona empilweni yabo.Abanye kufanele bacabangele ukuphila kahle kwezingane ezincane abaziphekelayo.Futhi-ke kukhona abafuna ukuqonda imiphumela izinqumo zabo ekhishini zibe nazo endaweni yonke.

I-PFOA, i-PTFE kanye Nomehluko Phakathi Kwalokhu Okubili

I-PFOA, emfushane nge-perfluorooctanoic acid, iyinhlanganisela yokwenziwa enezinhlelo eziningi zokusebenza.Kwaziwa ngokuxosha amanzi namafutha futhi isetshenziswa ekukhiqizeni ezinye ze-PTFE cookware.PTFE, into ehlukile, i-polymer yokwenziwa.Laziwa kakhulu ngegama lomkhiqizo we-polymer, okuwuphawu lokuhweba lweNkampani ye-DuPont.I-DuPont ingumkhiqizi wamakhemikhali ozinze e-US lapho, ngeminyaka yo-1930, isisebenzi sakhiqiza iqoqo lokuqala le-PTFE singaqondile ngenkathi sisebenza kuphrojekthi ehlukile.I-DuPont yaqala ngokushesha ukukhiqiza i-PTFE yezinhlelo zokusebenza zezimboni.I-PTFE yayidume ngokusetshenziswa njengevalvu kanye nesivali sepayipi phakathi neMpi Yezwe II yokuhlolwa kwenuzi eyaziwa nge-The Manhattan Project.Iqine ngokwedlulele futhi iqinile kodwa futhi iyavumelana nezimo, okuyenze yaba inketho enhle.

Izingozi ezingaba khona ze-PFOA ne-PTFE Cookware

I-cookware ehlanganiswe ne-PTFE isigunyazwe yi-FDA kusukela ngo-1960. Nokho, ulwazi olunganembile lubangele abantu abaningi besabe ukuthi ukupheka nge-polymer noma amanye amapani angagxili kungabangela umdlavuza noma ukugula. kuyingozi empilweni yabantu.Nakuba izingcezu ze-nonstick coating zingaphephuka zibe ukudla, lena akuyona ingozi yokuqala ehlotshaniswa namapani angagxili.Ngisho ne-American Cancer Society iyavuma ukuthi i-polymer/PTFE ayiyona i-carcinogen.I-PFOA esetshenziswa enqubweni yokukhiqiza engaba yingozi.I-PFOA yaziwa njenge-ejenti enobuthi, ebanga umdlavuza ezilwaneni.Isetshenziswa ekukhiqizeni ezinye, kodwa akuzona zonke izitsha zokupheka ze-PTFE ukuze zibophe i-PTFE kumkhumbi wokupheka.Ukuchayeka kwePFOA kuxhunyaniswa nomdlavuza wezinso kanye nomdlavuza wamasende, ukuqunjelwa, izinkinga zegilo, i-cholesterol ephezulu, nomfutho wegazi ophakeme ekukhulelweni.Kodwa, ukupheka ngamapani okuthosa angagxili akubhekwa njengomthombo ofanele noma okhathazayo wokuchayeka ku-PFOA.

Kungani ucabangela ezinye izindlela ze-PFOA-Free?

Kunezizathu ezimbili ezinkulu zokucabangela ezinye izindlela ze-PFOA-Free.Okokuqala, amapani amaningi angaqinile akufanele asetshenziselwe ukupheka ukushisa okuphezulu.Nakuba ukuchayeka kwe-PFOA nge-PTFE cookware kungeyona into ekhathaza kakhulu, cishe wonke amapani angagxili aqukethe i-fluorine, ikhemikhali esha lapho ishiselwe ngokweqile.Ukuchayeka kwe-fluorine kungaba yingozi kubantu nasezifuyweni ezifuywayo–ikakhulukazi izinyoni, ezinezinhlelo zokuphefumula ezizwela kakhulu.Nakuba amathuba okuchayeka okuphawulekayo engavamile, ukushisa ngokweqile kwe-nonstick cookware kungaholela esimweni esibizwa ngokuthi i-polymer-fume fever.Izimpawu zihlanganisa ikhanda elibuhlungu, imfiva nokugodola.Izinyoni ezifuywayo zingase zife ngenxa yokuchayeka ngokweqile.Ukuvimbela kuhilela ukungalokothi ushisise i-PTFE cookware ngaphezu kwamadigri angu-500.Lokhu kusho ukuthi uzodinga ukukhetha isitsha sokupheka esihlukile, njengama-cast iron skillet noma amapani ensimbi engagqwali okushisa izinyama noma yini enye edinga ukushisa okuphezulu.Kubalulekile futhi ukukhumbula ukuthi amapani angathosi akumele ashiswe ngaphambili–ngawoyela noma ngaphandle kwawo.Ngaphezu kwalokho, ngenkathi upheka nge-PTFE kungase kungalimazi wena nanoma ubani omphekayo, uma ekhiqizwa kusetshenziswa i-PFOA, kungase kulimaze omunye umuntu.

Ezinye izindlela ze-PTFE

Yize i-PTFE kusewuhlobo oludume kakhulu lwezitsha zokupheka ezingaqediwe, kukhona ezinye izindlela.I-Ceramic cookware iyindlela enhle etholakala ezindaweni zamanani ahlukahlukene.Ekuphenduleni ukukhathazeka nge-PFOA ne-PTFE, i-T-fal, umkhiqizi we-polymer wasekuqaleni wepani uze enze ulayini we-ceramic we-cookware.Njengamapani angagxili, abapheki kufanele bagweme ukunwaya izitsha zokubhaka zobumba futhi akufanele bazigcine zipakishwe ndawonye.Ukukhetha izitsha ezifanele namathuluzi okuhlanza kubalulekile uma kuziwa ekunakekeleni noma iyiphi i-nonstick pan: i-ceramic noma i-PTFE.
