Ingabe izinto zokumboza ezingamelana namafutha zingavuselelwa kanye nezikhwama zokudla zepulasitiki?

Ukubuyiselwa kwemikhombi yebhantshu ephakanyisiweyo yokudla kuyaphendula kumkhombi wokuphakanyisa, ubude bakho, nokuhambisana nesikhundla sokubuyiselwa esihlomile, noma kunezinhloso zokuphakanyisa ezinamandla amancane kanye nezinhloso ezingafaniyo ezinamandla amakhulu ekuthintana nokuprosesa kwemikhombi ngendlela yokuqondisa. Izinkhombi zokuvimbela okusetyenziswa kuzo amanzi nezinkhombi zezinkweli ezithile zihlukana ngokuphakamisa kanye nezinkhombi zokufinyelela emakhaya okubuyiselwa, kusiza ukuthi ipolimeya yesibopho isabuyiselwe kanye isaprocesiswe futhi ngokungabi nentsingiselo enkulu yendlela yokusebenza. Kepha, izinkhombi zokuphakanyisa eziphakanyiswa kakhulu okanye izinsimbi zokugcina zizoba zihlala zihlanganise ne-polimeya ngokuprosesa kwemikhombi, kungakhathali ukuthi kubuyekeze izinkinga zokusebenza kwemikhombi esabuyiselwe kanye kuzama ukuthinteka ukusetshenziswa kwawo kwezindawo zokugcina. Abasemthwakayo bakhetha kakhulu izinkhombi zokuphakanyisa ezinamandla okubuyiselwa ngokujabulisana nokunika ukuthi kungabi nempilo yekhaki, bakhumbula ukuthi izikhanda zokuphakanyisa ezinamandla kumele zihambisane nokusebenza okuhle kanye nokuziphatha kokugcina kwezindawo zokugcina ngokwesiqondiso sesikhundla sokubuyiselwa.

Izindlela zokuzilungisa ziziphi eziqondisa ukuthi iphakethi yamahlelo ayisiphambano nesithuthi nezinkukhu?

Ukuhlolwa okujwayelekile komkhakha kokumelana namafutha namafutha ezitsheni zepulasitiki zokudla kuhlanganisa ukuhlolwa kwe-kit kusetshenziswa amafutha ajwayelekile, ukukala isikhathi sokungena kwamafutha, nokuhlolwa kwezakhiwo zomshini ngemuva kokuchayeka kwama-lipid ngaphansi kwezimo ezilawulwayo. Ukuhlolwa kwe-kit kusetshenziswa amafutha anokucindezelwa okuhlukahlukene komhlaba ukuze kutholakale izinga eliphakeme lokumelana namafutha elingatholwa yindaba, kuyilapho ukuhlolwa kokungena kulinganisa isikhathi esidingekayo ukuze amafutha angene ngokucacile ezindongeni zesitsha lapho evezwa izinto ezithile zokuhlola emazingeni okushisa afanele. Amaphrothokholi okuhlola aphelele abuye ahlole izinguquko zezakhiwo zomshini kuhlanganise nokwehla kwamandla okudonsa, ukuguqulwa kokwelulwa, nokulahlekelwa kokuqina ngemva kwezinkathi ezibekelwe ukuchayeka kuma-simulants amafutha okudla, anikeze idatha eningi ebikezela ukusebenza kwezwe langempela
