Kodi poto wamkati wa chophikira mpunga ndi chiyani?
Kodi zokutira ndizovulaza thupi la munthu?Choyamba, tiyenera kumvetsetsa kapangidwe ka mphika wamkati wa chophikira mpunga.Dr. Leung Ka Sing, Pulofesa Wachiwiri wa dipatimenti ya Food Science and Nutrition, ku Hong Kong Polytechnic University, adanena kuti miphika yamkati ya ophika mpunga pamsika nthawi zambiri imakhala yopangidwa ndi aluminiyumu ndipo imawapopera ndi zokutira kuti asamamatire. pansi.Ananenanso kuti zokutira ndi mtundu wa pulasitiki wotchedwa polytetrafluoroethylene (PTSE), womwe sugwiritsidwa ntchito popaka zophikira mpunga, komanso mu wok.
Kutentha kwakukulu kwa wophika mpunga kumangofika 100 ° C, yomwe ili kutali kwambiri ndi malo osungunuka.
Ngakhale kuti Dr. Leung adanena kuti chophimbacho chimapangidwa ndi pulasitiki, adavomereza kuti anthu sayenera kudandaula kwambiri, "PTSE sidzatengeka ndi thupi la munthu ndipo idzatulutsidwa mwachibadwa ikalowa m'thupi.
