Kaya tipita kumalo odyera chakudya cham'mawa kapena kuyitanitsa kutenga, nthawi zambiri timawona chodabwitsa ichi: bwanayo adang'amba mwaluso thumba la pulasitiki, kenako ndikuliyika m'mbale, ndikuyikamo mwachangu chakudyacho.Ndipotu pali chifukwa chake.: Chakudya nthawi zambiri chimadetsedwa ndi mafuta.Ngati ikufunika kutsukidwa, zikutanthauza ntchito yowonjezera.Kwa mtundu wa bizinesi wa "voliyumu yayikulu ndi chidwi chochepa" monga malo odyetsera kadzutsa, thumba lapulasitiki lotsika mtengo limatha kuwabweretsera Kusavuta Kwambiri.
Koma palinso anthu ambiri omwe amatsutsa kwambiri izi, poganiza kuti matumba apulasitiki ndi "mankhwala".Poyerekeza ndi mbale zadothi zadothi, zimawoneka ngati zathanzi pamtunda, koma kwenikweni, zimakhala ndi chiopsezo chachikulu ku thanzi.Makamaka poika "zakudya zotentha kwambiri" monga Zakudyazi ndi supu zomwe zangotuluka kumene mumphika, mumamva bwino kununkhiza kwa fungo la pulasitiki, lomwe lingathe kuvomerezedwa monyinyirika pa kuwala, kapena kubwezeretsa ndi zovuta kumeza kwambiri, kuchititsa “mikangano” ina yosafunikira.
Ndiye kodi matumba apulasitiki alidi poizoni atadzazidwa ndi chakudya chotentha?
Choyamba, ndikofunika kumvetsetsa kuti matumba apulasitiki amapangidwa ndi "polyethylene", "polypropylene", "polyvinyl kolorayidi" ndi zina zotero.Malinga ndi akatswiri, polyethylene imakhala ndi chiwopsezo cha mvula ya "toxic monomer ethylene", koma kuthekera kwa mvula ya "polyethylene yachakudya" ndiyotsika kwambiri.Matumba apulasitiki omwe adafalikira kale nthawi zambiri amakhala opangidwa ndi "polypropylene", chifukwa amakhala ndi kutentha kwamphamvu kwambiri (160 ° -170 °), ndipo ngakhale atatenthedwa ndi microwave, sizitulutsa fungo lachilendo.Malinga ndi kutentha kwakukulu kwa chakudya pa 100 °, palibe pafupifupi "poizoni monomers" mu "matumba apulasitiki a polypropylene", koma mfundo ndi yakuti matumba apulasitiki omwe amagwiritsidwa ntchito ayenera kukhala "kalasi ya chakudya".
Kunena zowona: zomwe zimatchedwa "chinthu" mu "polypropylene" sizitanthauza kuti ndi mankhwala oopsa.Ndi bwino kuti musadye, koma simuyenera kudandaula kwambiri ngati mwadya.
