Mafuta opangidwa kwa nthawi yayitali, ma polyphenols ndi mafuta ofunikira omwe ali mu tiyi, amayamba kukhala oxidize, omwe amakhudza kukoma, mtundu ndi kukoma kwa chakumwa ndikuchepetsa kufunikira kwake kwa zakudya ndikuwononga mavitamini.
Ndipo tsopano asayansi atchula nthawiyo, yomwe ndi yabwino kwambiri popangira tiyi. Ndi 3 mphindi ndendende.
Tiyi woikidwa m'madzi otentha nthawi yayitali adafufuzidwa ndi akatswiri a toxicologists. Ndipo anapeza mu zitsanzo za zitsulo zolemera, makamaka lead, aluminiyamu, arsenic ndi cadmium. Ofufuza akukhulupirira kuti zitsulozo zinabwera m'masamba chifukwa cha kuipitsidwa kwa nthaka, nthawi zambiri chifukwa minda ili pafupi ndi malo owononga magetsi oyaka ndi malasha.
Momwe zinthu zovulaza zimatha kulowa mu chakumwa chanu, zimatengera nthawi yopangira tiyi. Chifukwa chake ngati thumba lili m'madzi kwa mphindi 15-17, kuchuluka kwa zinthu zapoizoni kumakwera kukhala kosatetezeka (mwachitsanzo, mu zitsanzo zina kuchuluka kwa aluminiyamu kumafika 11 449 µg/l pamene chololedwa tsiku lililonse 7 000 mg/ l).
Chifukwa chake simuyenera kupangira tiyi pa mfundo ya "kupanga ndi kuiwala", chifukwa mphindi zitatu ndizokwanira chakumwa chokoma, ndipo mphindi iliyonse mopitilira izi, zinthu zambiri zosafunikira zimalowa mu Cup yanu.
Zambiri zokomera tiyi penyani mu kanema pansipa:
