Kwipakethe ye-nitrogen, ukubunjwa komoya ngaphakathi kwesikhongozeli kulungelelaniswa, ngokuqhelekileyo ngokufaka i-nitrogen kwi-container ukuze ithathe indawo okanye inciphise ukuxinwa kwe-oksijini.Injongo yoku kukucothisa ukusabela kwe-oxidation kunye nokukhula kwe-microbial, ngokwandisa ubomi beshelufu yokutya.
Umgaqo wokupakishwa kwenitrogen kukunciphisa ukuxinana kweoksijini ekutyeni ngokususa okanye ukunciphisa ubukho beoksijini, ngaloo ndlela kuthomalalisa inkqubo yokonakala kokutya.I-nitrojeni yigesi engasebenziyo ngokwekhemikhali ekutyeni kwaye ayichaphazeli incasa kunye nokubunjwa kokutya.
Ngokupakishwa kwenitrogen, ukutya kunokugcinwa kukutsha kwaye kunencasa entle, kwaye ukuhla komgangatho wokutya kunokuncipha.Le teknoloji yokupakisha isetyenziswa ngokubanzi kwiimveliso zokutya ezahlukeneyo ezifana nenyama, iziqhamo, imifuno, i-delicatessen, iimveliso zobisi kunye neepastries.
Kufuneka kuqatshelwe ukuba ukupakishwa kwe-nitrogen akubhubhisi ibhaktheriya okanye i-microorganisms esele ikhona ekudleni, ibambezela ukukhula kwayo kunye nokonakala ngokulungelelanisa umoya ojikelezayo.Ngoko ke, xa usebenzisa ukupakishwa kwe-nitrogen, kusafuneka ukuba ubeke ingqalelo ekuphatheni okucocekileyo kokutya kunye neemeko ezifanelekileyo zokugcina ukuqinisekisa ukhuseleko kunye nomgangatho wokutya.
Lithini ifuthe elithile lokupakishwa kwenitrogen kwishelufu yobomi bokutya?

3. Gcina isakhiwo sokutya kunye nokuthungwa: Ukupakishwa kwe-nitrogen kunokugcina ukwakheka kunye nokuthungwa kokutya, ukuthintela ukutya ekuxininiseni, ukukhubazeka okanye ukuthambisa ngexesha lokupakisha.Oku kudlala indima ebalulekileyo ekugcineni inkangeleko, ukuthungwa kunye nomgangatho wokutya okuthile okunjengokutya okune-crispy, ama-pastries, njl.
4. Ukuthintela ukuthotywa kwezinto ezinobuthathaka be-oksijini: Okunye ukutya kuqulethe izinto ezingenayo i-oxygen, ezifana neevithamini, i-anthocyanins, njl. kunye nombala ekutyeni.
Ukupakishwa kwe-nitrojeni akupheli ii-microorganisms esele zikhona okanye zandise ubomi beshelufu yokutya ngokungenasiphelo.Ezinye izinto, ezifana nokutsha kokutya, ukuphathwa ngokucoceka, ubushushu bokugcina, njl., zisenempembelelo ebalulekileyo kubomi beshelufu.Ngoko ke, xa usebenzisa ukupakishwa kwe-nitrogen, kuseyimfuneko ukudibanisa ukuphatha ukutya okuchanekileyo kunye neendlela zokugcina ukuqinisekisa ukhuseleko kunye nomgangatho wokutya.
Zeziphi iintlobo zokutya ezilungele ukupakishwa kwenitrogen?
1. Inyama entsha kunye neenkukhu: Ukupakishwa kwe-nitrogen kwandisa ubomi beshelufu yenyama entsha kunye neenkukhu, ezifana nenyama yenkomo, ihagu, imvana, inkukhu, intlanzi, njl.
2. Ukutya kwaselwandle kunye neemveliso zasemanzini: ukupakishwa kwenitrogen kunokwandisa ubomi beshelufu yezilwanyana zaselwandle kunye neemveliso zasemanzini, njengentlanzi, i-shrimp, i-shellfish, i-crab, njl.
3. Iziqhamo kunye nemifuno: Ukupakishwa kwe-nitrogen kunokwandisa ubomi beshelufu yeziqhamo kunye nemifuno, njengama-apile, amapere, amaqunube, iidiliya, iitumato, i-lettuce, njl. yeziqhamo nemifuno.
4. Ukutya okuphekiweyo kunye nokucutshungulwayo: I-nitrogen yokupakisha ifanelekile kuzo zonke iintlobo zokutya okuphekiweyo kunye nokucutshungulwa, njenge-ham, i-sausage, iimveliso zenyama, iimveliso zobisi, isonka, i-pastries, njl. ukwakheka kunye nencasa yazo.
5. Amantongomane kunye neziqhamo ezomileyo: Ukupakishwa kwe-nitrogen kwandisa ubomi beshelufu yamandongomane kunye neziqhamo ezomisiweyo ezifana ne-walnuts, i-almonds, i-cashews, iirasentyisi, njl.
Ngaba ukupakishwa kwenitrogen kunalo naliphi na ifuthe kwixabiso lesondlo sokutya?
I-Modified Atmosphere Packaging (MAP) inempembelelo encinci kwixabiso lesondlo sokutya, ngakumbi ngokwandisa ubomi beshelufu yokutya ukuze kugcinwe uzinzo lwezondlo.
Nazi ezinye izinto eziphambili ezithathwayo malunga nempembelelo yokupakishwa kwenitrogen kwixabiso lesondlo sokutya:
