Muva nje, abanye abathengi baxoxisane ngendlela yokuthengai-vacuum ihlanganisiweukudla.Kuyaqondwa ukuthi okwamanje, kunezindlela ezintathu zokugcina ukudla kukusha: ukugcwalisa nge-nitrogen, ukuhlanza kanye nokwengeza izivimbelakuvunda.Ukugcinwa kwe-vacuum kulula, kungokwemvelo futhi kunempilo.
Ukufakwa kwe-vacuum kusho ukuthiisikhwama sokupakisha se-vacuumugcwalisa ifomu lokugcina lokuqukethwe okupakishiwe emshinini wokupakisha we-vacuum.Esinye sezixhumanisi ezibalulekile ukukhishwa komoya kanye ne-deoxidization, okuwukuvimbela ukudla ekukhunjeni nasekuboleni.Omunye umsebenzi obalulekile we-vacuum deoxidization ukuvimbela i-oxidation yokudla.Isibonelo, ukudla okunamafutha kuqukethe inani elikhulu lama-acids angama-unsaturated, okulula ukushintsha umbala nokunambitha nge-oxidation.Ukuvalwa kwe-vacuum kungahlukanisa kahle umoya ku-oxidation, futhi kugcine umbala, ukunambitheka kanye nenani lokudla okunomsoco.
Kuyaphawuleka ukuthiukufakwa kwe-vacuumyona ngokwayo ayinawo umphumela wokuvala inzalo.Ukuze ukwazi ukusizakala ngempela ngezinzuzo zobuchwepheshe bokupakisha be-vacuum, kuyadingeka futhi ukwenza inzalo edingekayo ngemva kokuphothulwa kokufakwa kwe-vacuum, njengokuvala izinga lokushisa eliphezulu, ukuvala inzalo nge-irradiation, njll. Noma yikuphi ukudla okonakalayo okudingeka kufakwe esiqandisini. kusafanele ifakwe esiqandisini noma iqandiswe ngemva kokufakwa kwevacuum.Ukupakisha i-vacuum akuyona enye indlela yesiqandisi noma ukulondolozwa kweqhwa.Ngaphezu kwalokho, isikhathi sokugcinwa kwe-vacuum yezinto zokudla ezigcinwe emazingeni okushisa ahlukene sihlukile.
Indlela yokukhetha ephephilei-vacuum ihlanganisiweukudla?
Okokuqala, bheka isikhwama sokuvuvukala
Ukuthi ukunweba isikhwama kuyindlela enembile futhi elula yokuthi abathengi bahlulele ukuthiukudla vacuum emaphaketheniiwohlokile.Ngokomqondo ojwayelekile wefiziksi, ngaphansi kwezimo ezijwayelekile, umfutho womoya osesikhwameni sokudla esipakishiwe kufanele uhambisane nezwe langaphandle noma ube ngaphansi kwezwe langaphandle ngemva kokuhlanza.Uma isikhwama sandiswa, kusho ukuthi ukucindezela komoya esikhwameni kuphakeme kunezwe langaphandle, okusho ukuthi amagesi amasha akhiqizwa esikhwameni esivaliwe.Lawa magesi angama-metabolites akhiqizwa ngemuva kokukhiqizwa okuningi kwama-microorganisms, ngoba inani elincane lama-metabolites amancane alanele ukwandisa isikhwama.Iningi lamagciwane noma isikhunta (amagciwane e-lactic acid, imvubelo, i-aerogenes, i-polymyxobacillus, i-Aspergillus, njll.) engase ibangele ukonakala kokudla izokhiqiza inani elikhulu lamagesi ohlelweni lokubola amaprotheni noshukela ekudleni, njenge-carbon dioxide, i-hydrogen sulfide, i-ammonia, i-alkane, njll., “evuthela” isikhwama sokupakisha sibe ibhaluni.Phakathi nenqubo yokuvala inzalo yokudla ngaphambi kokupakishwa, ama-microorganisms nama-buds awakabulawanga ngokuphelele.Ngemva kokupakishwa, ama-microorganisms ayanda ngobuningi, abangela ukonakala.Ngokwemvelo, inkinga yokuqhuma kwezikhwama zokufaka iyenzeka.
Okwesibili, iphunga
Lapho uthengai-vacuum ihlanganisiweukudla, ungathathi iphunga lokudla njengendinganiso yokwahlulela.Uma ukunambitheka kokudla kuphuma ephaketheni, kusho ukuthiukufakwa kwe-vacuumyona ngokwayo ayisekho i-vacuum, futhi kukhona ukuvuza komoya.Lokhu kusho ukuthi amagciwane angakwazi “ukugeleza” ngokukhululeka.
Okwesithathu, amamaki okuhlola
Ukuze uthole iphasela lokudla, qala uhlole ukuthi ilayisense yalo yokukhiqiza, ikhodi ye-SC, umkhiqizi kanye nohlu lwezithako luphelele yini.Lezi zitifiketi zifana “namakhadi omazisi” okudla.Ngemuva kwalezi zitifiketi kukhona “impilo yakudala neyamanje” yokudla, lapho bevela khona nalapho bebekhona.
Okwesine, qaphela kakhulu impilo yeshalofu yokudla
Ukudla okuseduze nempilo yayo yeshalofu akuyingozi, kodwa umbala wayo nokudla kuzokwehla.Ngemva kwei-vacuum ihlanganisiwekuvulwa ukudla, kufanele kudliwe ngokushesha ngangokunokwenzeka futhi akufanele kugcinwe esiqandisini.Uma uthenga "ukuthenga umuntu uthole ukudla okukodwa mahhala", naka usuku lokukhiqiza kanye nempilo yeshelufu yezimpahla eziboshiwe.
