Njira yoyeretsera chakudya yomwe imafunika popanga chakudya chosiyanasiyana ndi yosiyana. Opanga chakudya ayenera kugula miphika yoyeretsera chakudya kuti awonjezere nthawi yogwiritsira ntchito chakudya. Ayenera kuyeretsa chakudya pa kutentha kwakukulu kwa kanthawi kochepa, zomwe sizimangopha mabakiteriya omwe angadwale chakudyacho, komanso zimasunga zakudya zofunika komanso mtundu, fungo, ndi kukoma kwa chakudya kuti zisawonongeke.
Zakudya za nyama ziyenera kusungidwa mufiriji pa -40 digiri Celsius pambuyo poti zapakidwa mu vacuum ndi makina opakizira vacuum, kenako nkusungidwa pa -18 digiri Celsius kwa miyezi itatu. Ngati zosungira ziwonjezedwa ku zakudya zophikidwa, nthawi zambiri zimatha kusungidwa kwa masiku 15 pogwiritsa ntchito vacuum packaging. Ngati zasungidwa kutentha kochepa, zitha kusungidwa kwa masiku 30. Komabe, ngati zosungira siziwonjezedwa, ngakhale phukusi la vacuum litagwiritsidwa ntchito ndikusungidwa kutentha kochepa, zitha kusungidwa kwa masiku atatu okha. Patatha masiku atatu, kukoma ndi kukoma zidzakhala zoyipa kwambiri. Zinthu zina zitha kusungidwa kwa masiku 45 kapena 60 pamatumba awo opakizira, koma kwenikweni ndi zolowera m'masitolo akuluakulu. Chifukwa cha malamulo m'masitolo akuluakulu, ngati nthawi yosungira zinthu ipitilira gawo limodzi mwa magawo atatu a zonse, katunduyo sangalandire, ngati nthawi yosungira zinthu ipitilira theka, ayenera kuchotsedwa, ndipo ngati nthawi yosungira zinthu ipitirira magawo awiri mwa atatu, ayenera kubwezedwa.
Ngati chakudya sichinayeretsedwe pambuyo poyika vacuum cleaner, sichidzawonjezera nthawi yogwiritsira ntchito chakudya chophikidwa. Chifukwa cha chinyezi chambiri komanso zakudya zambiri zomwe zimadyedwa, chimatha kufalikira mosavuta ndi mabakiteriya. Nthawi zina, kuyika vacuum cleaner kumathandizira kuti zakudya zina ziwole. Komabe, ngati njira zoyeretsera zitengedwa pambuyo poyika vacuum cleaner, nthawi yogwiritsira ntchito vacuum cleaner imasiyana kuyambira masiku 15 mpaka masiku 360 kutengera zofunikira zosiyanasiyana zoyeretsera. Mwachitsanzo, mkaka ukhoza kusungidwa bwino kutentha kwa chipinda mkati mwa masiku 15 pambuyo poyika vacuum cleaner ndi kuipitsa mu microwave, pomwe nkhuku yosuta imatha kusungidwa kwa miyezi 6-12 kapena kupitirira apo pambuyo poyika vacuum cleaner ndi kuipitsa kutentha kwambiri. Mukagwiritsa ntchito makina oyika vacuum cleaner poyika vacuum cleaner, mabakiteriya amachulukirabe mkati mwa chinthucho, kotero kuipitsa kuyenera kuchitika. Pali mitundu ingapo ya kuipitsa, ndipo ndiwo zamasamba zina zophikidwa sizifunika kutentha kopitirira madigiri 100 Celsius. Mutha kusankha mzere woyika pasteurization. Ngati kutentha kukupitirira madigiri 100 Celsius, mungasankhe ketulo yoyeretsera yotenthetsera yotenthetsera yotenthetsera kwambiri kuti muyeretse.
