Iukupakisha isitoreji esibandayokanye ne-cryopreservation yokudla kunganciphisa ukuphefumula kwamangqamuzana okudla ahlukahlukene futhi kuvimbele ukukhula nokuthuthukiswa kwamangqamuzana okudla amasha ekuvuthweni nasekuvuthweni, okuholela ekuboleni nasekuwohlokeni kokudla, imifino emisha nezithelo ezintsha;Ngakolunye uhlangothi, ukudla okuqandisiwe kanye neqhwa futhi kuvimbela ikhono lomsebenzi we-microorganisms, okuyisici esiyinhloko esibangela ukonakala kokudla, futhi kukhiqiza lokho okubizwa ngokuthi umphumela wokuhlanza amabhaktheriya, ongandisa isikhathi seshelufu sokudla.Ngakho-ke, indlela yokugcina amavidiyo emaphaketheni afakwe efrijini naseqandisiwe isetshenziswa kakhulu.
Ukudla okuqandisiwe okuqandisiwe kungahlukaniswa kube isiqandisi esinqunu kanye nesiqandisi sokupakisha.Isiqandisi esinqunu sifanelekile ukudla okuningi okukhulu, njengengulube, inyama yenkomo, inkukhu, idada, inani elikhulu lezithelo nemifino.Njengoba umswakama ubuye uphansi kakhulu ekushiseni okuphansi, ukwelashwa kokulawula umswakama kufanele kwenziwe endaweni yokugcina impahla, ngaphandle kwalokho ukulahlekelwa kwenani elikhulu lomswakama kuzomisa ukudla futhi kulahlekelwe ukunambitheka kokuqala okusha.Indlela elula ukumboza ubuso.Ukusetshenziswa kwefilimu yepulasitiki enomoya ophansi kanye nokungena komswakama kungavimbela ukulahleka kwamanzi, futhi kulula nokusebenza ngomshini efrijini.
Isitoreji esibandayo ngaphansi kokupakishwangokuvamile ihlanganiswa nokupakishwa kwe-aseptic, ukupakishwa kwe-deaeration, ukupakisha esikhundleni segesi nezinye izindlela zokupakisha, ezingandisa kakhulu impilo yesevisi yokudla.Izinto zokupakisha eziqandisiwe zingakhethwa.Kumelwe babe namandla amahle okudweba, amandla omthelela, ukumelana nokubhoboza, amandla okuvala ukushisa kanye nokuguquguquka ezingeni lokushisa eliphansi, ukuze balondoloze amandla amahle kanye nokuqina.
At lokushisa low, umswakama permeability ofifilimu yepulasitikikuyehla futhi ukumelana nomswakama kuyathuthuka.Ngokukhula kwesikhathi, ukugcwala komoyampilo esikhwameni sokudla esipakishiwe kuzokwanda, kodwa ukwanda kokuhlushwa komoyampilo ekushiseni okuphansi kuncipha.Yiqiniso, uma ukudla okupakishwe esikhwameni kunomsebenzi wokuphefumula kwamangqamuzana, khona-ke umoya-mpilo uzoncishiswa futhi i-carbon dioxide izokwanda.Ngenxa yokuthi amangqamuzana aphefumula futhi amunca umoya-mpilo futhi akhiphe igesi ye-carbon dioxide, ngcono umgoqo wefilimu, kuba lula ukufeza isimo sokulondolozwa kwamangqamuzana, okungukuthi, lapho okuqukethwe komoyampilo kungaphansi kuka-2% futhi i-carbon dioxide ingaphezulu. ngaphezu kuka-8%, amaseli asesimweni sokulala, ukuze andise isikhathi sokulondoloza.
Ukupakisha ukudla okuqandisiweingasetshenziselwa isitoreji esiqandisiwe sokudla okulandelayo: iyogathi, isiphuzo se-lactobacillus, ukhilimu, ushizi, ubisi lwesoya, ama-noodle amasha, i-tofu, i-ham, isoseji, inhlanzi efakwe emanzini anosawoti, inhlanzi ebhenywayo, imikhiqizo yasemanzini, ukhukhamba, ukupheka okuhlukahlukene, ukupheka okujwayelekile, i-hamburger, i-pizza eluhlaza njll.
