Kutshanje, abanye abathengi baye babonisana ngendlela yokuthengavacuum ipakishweukutya.Kuyaqondwa ukuba okwangoku, kukho iindlela ezintathu zokugcina ukutya kutsha: ukuzaliswa nge-nitrogen, ukucoca kunye nokongeza izilondolozo.Ukugcinwa kwevacuum kulula, kuyindalo kwaye kusempilweni.
Ukupakishwa kweVacuum kuthetha ukubaibhegi yokupakisha ivacuumugqibezela ifom yokugqibela yeziqulatho ezipakishiweyo kumatshini wokupakisha wevacuum.Olunye unxulumano olubalulekileyo kukutsalwa komoya kunye ne-deoxidization, oko kukuthintela ukutya kwi-mildew kunye nokubola.Omnye umsebenzi obalulekileyo we-vacuum deoxidization kukuthintela i-oxidation yokutya.Ngokomzekelo, ukutya okunamafutha kuqulethe inani elikhulu le-unsaturated fatty acids, ekulula ukutshintsha umbala kunye nokunambitha nge-oxidation.Ukutywinwa kwevacuum kunokwahlula ngokufanelekileyo umoya kwi-oxidation, kwaye kugcine umbala, incasa kunye nexabiso lesondlo sokutya.
Kufanelekile ukuphawula okoukupakishwa kwevacuumyona ngokwayo ayinasiphumo sokuvala inzala.Ukuze usebenzise ngokwenene inzuzo yetekhnoloji yokupakisha i-vacuum, kuyafuneka ukuba kwenziwe inzala eyimfuneko emva kokugqitywa kokufakwa kwe-vacuum, efana ne-high-temperature sterilization, i-irradiation inzalo, njl. Kusafuneka ifakwe efrijini okanye ibekwe emkhenkceni emva kokupakishwa kwevacuum.Ukupakishwa kwevacuum akuyona enye indlela yokubeka efrijini okanye ukugcinwa komkhenkce.Ngaphezu koko, ixesha lokugcinwa kwevacuum yezinto zokutya ezigcinwe kumaqondo obushushu ahlukeneyo lahlukile.
Indlela yokukhetha ekhuselekileyovacuum ipakishweukutya?
Okokuqala, jonga ingxowa yokudumba
Nokuba ukwandisa ibhegi yeyona ndlela ilula kwaye iluncedo kubathengi ukuba bagwebe ukubaukupakishwa kwevacuum yokutyaiye yaba mandundu.Ngokwengqondo eqhelekileyo yefiziksi, phantsi kweemeko eziqhelekileyo, uxinzelelo lomoya kwingxowa yokutya epakishweyo kufuneka ihambelane nelizwe langaphandle okanye ngaphantsi kwelizwe langaphandle emva kokucoca.Ukuba isikhwama sandiswa, kuthetha ukuba uxinzelelo lomoya kwisikhwama luphezulu kunehlabathi langaphandle, oku kuthetha ukuba iigesi ezintsha ziveliswa kwisikhwama esitywiniweyo.Ezi gesi ziyi-metabolites ezenziwe emva kokuveliswa kobuninzi be-microorganisms, kuba inani elincinci le-metabolites ye-microbial alanele ukwandisa isikhwama.Uninzi lweebhaktheriya okanye i-molds (i-lactic acid bacteria, igwele, i-aerogenes, i-polymyxobacillus, i-Aspergillus, njl.) enokubangela ukonakala kokutya kuya kuvelisa inani elikhulu leegesi kwinkqubo yokubola iprotheni kunye neswekile ekudleni, njenge-carbon dioxide, i-hydrogen sulfide, i-ammonia, i-alkane, njl., "evuthela" isikhwama sokupakisha kwibhaluni.Ngexesha lenkqubo yokutyala inzala ngaphambi kokupakishwa, ii-microorganisms kunye ne-buds azizange zibulawe ngokupheleleyo.Emva kokupakisha, ii-microorganisms zikhula ngamanani amakhulu, zibangela urhwaphilizo.Ngokwemvelo, ingxaki yokukhutshwa kweengxowa zokupakisha kwenzeka.
Okwesibini, ivumba
Xa uthengavacuum ipakishweukutya, musa ukuthatha ivumba lokutya njengomgangatho wesigwebo.Ukuba incasa yokutya ichitheka ngaphandle kokupakishwa, oko kuthetha ukubaukupakishwa kwevacuumngokwayo ayisekho ivacuum, kwaye kukho ukuvuza komoya.Oku kuthetha ukuba iibhaktheriya ziyakwazi "ukuhamba" ngokukhululekileyo.
Okwesithathu, amanqaku okuhlolwa
Ukufumana iphakheji yokutya, qala ujonge ukuba ingaba ilayisenisi yayo yokuvelisa, ikhowudi ye-SC, umenzi kunye noluhlu lwezithako lugqityiwe.Ezi zatifikethi zifana “namakhadi esazisi” okutya.Emva kwezi ziqinisekiso kukho “ubomi bangaphambili nobangoku” bokutya, apho babevela khona nalapho bebekhe bahlala khona.
Okwesine, nikela ingqalelo engqongqo kwishelufu yobomi bokutya
Ukutya okukufutshane kwishelufu yayo akuyingozi, kodwa umbala wayo kunye nesondlo siya kuncipha.Emva kwevacuum ipakishweukutya kuvulwa, kufuneka kudliwe ngokukhawuleza kwaye akufanele kugcinwe efrijini.Xa uthenga "ukuthenga umntu ufumane enye yasimahla" ukutya, nikela ingqalelo kumhla wokuvelisa kunye nobomi beshelufu bempahla ebotshiweyo.
