Kukho amathuba okukhula kwimakethi yokutya okomisiwe ngumkhenkce nokuba ungumenzi omiselweyo owandisa ipotfoliyo yakho, okanye umtsha kwimarike.Yenza imveliso yakho igqame ngokupakisha ukutya okomileyo okukhenkcezayo okuthengisa imveliso yakho eyomisiweyo kwaye ikhusela imveliso.
Ukupakishwa kwethu lolona khetho lulungileyo lokukhenkceza-yomileyo, iigesi, ezinjenge-CO2, kunye ne-Oxygen inokuthintelwa ngokupheleleyo ukuba ingangeni kwiphakheji.Ukutya okunamafutha ukuncipha kokufuduka kweoksijini kubalulekile ukunciphisa nokunciphisa ukusabela kwe-oxidative.Okunye ukutya okomileyo okuphefumlayo (okufana neziqhamo kunye nemifuno) kufuna i-polyethylene, okanye i-polyvinylidene chloride ene-permeability ephantsi yomswakama kunye nokunyuka kwegesi ephezulu.
