Kawirikawiri zimakhala zowonjezera mavitamini a soya. Kulowa mu thupi laumunthu, limasanduka mtundu wa shuga, ndipo kugwiritsidwa ntchito kawirikawiri kumapangitsa kuti muwonjezeke kwambiri m'chiwindi, zomwe zimabweretsa kunenepa kwambiri. Zakudya zopangidwa pamwambazi zagwedezeka mu mtanda, zomwe zimapangidwira, ndipo zimatenthedwa ndi mafuta otentha pamtunda wa madigiri 250. Kawirikawiri mafuta amagwiritsa ntchito mafuta otsika mtengo, monga mafuta oyeretsa okwera mtengo kwambiri omwe amakhudza mtengo wamagetsi otsirizira, kupanga kupanga zopanda phindu. Tiyenera kuzindikira kuti teknoloji yopanga zipsera imapereka mpata woposa masekondi 30, koma lamuloli silikupezeka kawirikawiri m'mapangidwe amakono.
Kukoma kwa makapu opangidwa ndi teknolojia iyi ndi yosiyana kwambiri ndi ya mbatata, zovunditsa zosiyanasiyana ndi zowonjezera zimagwiritsidwa ntchito kusintha. Zowonjezera zowonjezera ndi sodium glutamate. Ponena za kuvulazidwa kwake kwalembedwa zambiri, zofunikira zofunika zitha kupezeka mosavuta. Tiyenera kukumbukira kuti chifukwa cha sodium glutamate, ngakhale zakudya zopanda pake zimakhala zomwe mumafuna kudya mobwerezabwereza, zomwe zimapangitsa kuti opanga chips amvetse.
Kuopsa kwa chips pa thupi

Pali opanga omwe amagwiritsa ntchito mbatata weniweni kupanga zipsu. Komabe, nthawi zambiri zimasinthidwa ndi majini, monga momwe zilili, zikuluzikulu ndi zowonongeka za tubers - sizidya ndi tizirombo. Kuphika mapepala a mbatata, mafuta otchipa amagwiritsidwanso ntchito.
Pogwiritsa ntchito njira yotentha ndi mbatata, zonse zomwe zimapindulitsa zimathetsedwa, ndipo zoterezi zimakhala zozizira. Pa kuwonongeka kwa mafuta, acrolein imapangidwa, yomwe imakhala ndi khansa komanso zamagetsi. Maphunziro ake amapezeka ngakhale ndi kusunga chipangizo chamakono kwambiri. Kuti muchepetse kuchuluka kwa kapangidwe ka mankhwalawa, muyenera kusintha nthawi zonse mafuta kuti mutenge.
Kansitrogina ina komanso yowopsa kwambiri ndi acrylamide, yomwe ingapangidwe ngakhale panyumba, ngati mafuta otuka kapena ozizira ndi otentha kwambiri.
Posachedwapa, pofufuza mu chips, chinthu chomwe chimatchedwa glycidamide, wachibale wapafupi kwambiri wa acrylamide, chapezeka kuti sichikhoza kuchititsa kansalu kansalu chabe, komanso kuwonongedwa kwa DNA. Nanga ndi poizoni angati omwe ali mu chips, mpaka atakhala ndi nthawi yophunzira?
Pali mtundu wa zipsu, monga mpweya, zomwe zili ndi poizoni pang'ono kuposa mitundu ina ya chips. Katswiri wamakono omwe amapanga amawathandiza kuti ayambe kudya mwachangu kwa mphindi 10, komabe, amapeza mavitamini ena. Kawirikawiri, opanga amakhala opindulitsa kwambiri pogwiritsa ntchito mitundu yonse ya zosakaniza kuti apange makapu, chifukwa apange makilogalamu imodzi a zinthu zomwe mukufunikira kuti mukhale ndi makilogalamu 5 a mbatata.
Tonse tamva za kuopsa kwa zipsinjo za umoyo waumunthu, komabe okonda mankhwalawa amagula izo, nthawi zambiri podziwa kuti kudya chips kumayambitsa gastritis, kupweteka kwa mtima, matumbo ndi chifuwa. Mchere wochuluka, womwe uli mu chips, umakopa ambiri okonda "mchere". Komabe, kupitirira kwake m'thupi kumabweretsa kulepheretsa kukula kwa mafupa, chitukuko cha matenda a mtima ndi matenda opatsirana.
