Iphepha lokucoca ioyile yaseTshayina-Amaphepha okucoca ioyile alungele zonke iintlobo zokuhluza ioyile-Udonga olukhulu.

1. Iimpawu zokusetyenziswa kwephepha lokucoca ioyile etyiwayo:
• Ukumelana nobushushu obuphezulu.Inokuthi ifakwe kwi-oyile ye-200 ngaphezu kweentsuku ze-15.
• Unomndilili ophezulu weqhezu elingenanto.Ukungcola okukuko kunye ne-avareji yokungabikho kwee-microns ezingaphezu kwe-10.Yenza ioli yokuthosa icace kwaye ibonakale, kwaye ufezekise injongo yokucoca into emisiweyo kwioli.
• Unomoya omkhulu wokungena emoyeni, onokuvumela izinto zegrisi ezine-viscosity ephezulu ukuba zidlule kakuhle, kwaye isantya sokucoca sikhawuleza.
• Amandla aphezulu owomileyo kunye namanzi: xa amandla okuqhuma afikelela kwi-300KPa, amandla e-longitudinal kunye ne-transverse tensile yi-90N kunye ne-75N ngokulandelanayo.

2. Iinzuzo zokusetyenziswa kwephepha lokuhluza ioli etyiwayo:
• Unokuzisusa ngempumelelo izinto ezibangela umhlaza ezifana ne-aflatoxin kwioli yokuqhotsa.
• Inokususa amavumba kwioli yokuqhotsa.
• Inokususa iiasidi ezinamafutha asimahla, iiperoxide, iipholima eziphezulu zemolekyuli kunye nokungcola okusesantini ejingayo kwioli yokuqhotsa.
• Inokuphucula ngokufanelekileyo umbala weoli yokuthosa kwaye iyenze ifezekise umbala ocacileyo weoli yesaladi.
•Inokuthintela ukwenzeka kweoyile yokuqhotsa ioxidation kunye nerancidity reaction, iphucule umgangatho weoyile yokuqhotsa, iphucule umgangatho wococeko lokutya okuqhotsiweyo, kunye nokwandisa ixesha leshelufu lokutya okuqhotsiweyo.
• Unokusebenzisa ngokupheleleyo i-oyile yokuqhotsa phantsi kwesiseko sokuthobela imimiselo yococeko lokutya, ukuzisa inzuzo engcono yezoqoqosho kumashishini.Le mveliso isetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zokucoca ioli yokuqhotsa
Idatha yaselabhoratri ibonisa ukuba ukusetyenziswa kwephepha lokuhluza i-oyile etyiwayo kudlala indima ebalulekileyo ekuthinteleni ukwanda kwexabiso le-asidi ye-oyile yokuqhotsa, kwaye kubaluleke kakhulu ekuphuculeni indawo yokuqhotsa, ukuphucula umgangatho wemveliso, kunye nokwandisa ixesha leshelufu yemveliso.
