Izithiyo zepulasitiki ezikwazi ukumelana nokushisa okuphezulu kwe-microwave zibuyisela emuva isikhwama sesikhwama sokudla okuphekwe kuqala

Okubizwa ngokuthi ukupakishwa kwesikhwama se-retort kuwuhlobo lwesikhwama sokupakisha se-vacuum, kodwa uma kuqhathaniswa nezikhwama zokupakisha ze-vacuum ezijwayelekile, isikhwama se-retort ngokuvamile senziwe ngefilimu ye-polyester, ifilimu ye-polypropylene kanye ne-aluminium foil, enezinto ezihlukahlukene kanye nesakhiwo se-multi-layer, okwenza isikhwama se-retort sinezici zokumelana nezinga lokushisa eliphezulu, ukukhanya nokumelana nomswakama.....Funda kabanzi
