Kwiphakheji ye-nitrogen, ukwakhiwa komoya ngaphakathi kwesikhongozeli kuhlengahlengiswa, ngokufuthi ngokufaka i-nitrogen kwisitya sokutshintsha okanye ukunciphisa uxinzelelo lweoksijini. Injongo yoku kukuphinda kwenziwe kancinci i-oxidation kunye nokukhula kwe-rolitial, ngaloo ndlela kudlulise ubomi bokutya.
Umgaqo-nkqubo we-Nitrojeni ukupakisha kukunciphisa uxinzelelo lweoksijini ekutyeni ngokususa okanye ukunciphisa ubukho beoksijini, ngaloo ndlela kukucotha inkqubo yokutya. I-nitrogen yirhasi ye-intert engasasebenzi kakuhle ngokutya kunye nokutya kwaye ayichaphazeli incasa kunye nokuthathwa kokutya.
Ngephangisi e-nitrogen, ukutya kunokugcinwa intsha kwaye inambitha elungileyo, kunye nokupheliswa komgangatho wokutya kunokuncitshiswa. Le teksti yokupakisha isetyenziswa ngokubanzi kwiintlobo ngeentlobo zeemveliso zokutya ezinje ngenyama, iziqhamo, imifuno, i-decrictsen, iimveliso zobisi kunye ne-pastries.
Kuya kufuneka kuqatshelwe ukuba ukupakisha i-nitrogen ayitshabalali intsholongwane okanye i-microorganisms esele ikho ekutyeni, ilibazisa kuphela ukukhula kwayo kunye nexhoba ngokuhlengahlengiswa kwemozulu yomhlaba. Ke ngoko, xa usebenzisa ukupakisha i-nitrogen, kuseyimfuneko ukunikela ingqalelo ekuphathweni okucocekileyo kokutya kunye neemeko ezifanelekileyo zokugcina ukuqinisekisa ukhuseleko kunye nomgangatho wokutya.
Yintoni ifuthe elithile lephakheji ye-nitrogen kubomi bokutya?
I-1. Ukuthintela ukuphendula okuphezulu: Ukupakisha i-nitrogen kuyacotha kwimpendulo ye-oxidation ngokunciphisa uxinzelelo lweoksijini kwiphakheji kunye nokunciphisa unxibelelwano lweoksijini ekutyeni. Ukuphendula kwe-oxidation yenye yezona zinto zibangela ukonakala kokutya kunye nokonakaliswa komgangatho, ezinje nge-oxidation kunye ne-pigment ukutshintsha kokutya. Ngokuthintela ukuphendula kwe-Oxidication, ukupakisha i-nitrogen kunokwandisa ubomi beshelfu yokutya.
2. Lawula ukukhula kwe-rolial: Ukupakisha i-nitrogen kunokunciphisa isixa seoksijini ngaphakathi kwephakheji, ngaloo ndlela kunqunyulwe ukukhula kweentsholongwane, kubumbani kunye negwele. Le microorganisms yenye yezona zinto ziphambili ezikhokelela ekutyani kweSporelage kunye neSpoilage. Ngokulawula ukukhula intsholongwane, ukupakisha i-nitrojeni kunceda ukwandisa ubomi bokutya.
3. Gcina ubume bokutya kunye nokuhlengahlengiswa kwe-nitrojel kunokugcina isakhiwo kunye nokuhlengahlengiswa kokutya, ukuthintela ukutya ekucinezelweni, kuthathelwe ingqalelo okanye kuthathwe ngexesha lenkqubo yokupakisha. Oku kudlala indima ebalulekileyo ekugcineni inkangeleko, ukuthungwa kunye nomgangatho wokutya okuthile njengokutya okuphekiweyo, amadlelo, njl njl.
4. Thintela ukonakaliswa kwezinto ezibuthathaka zeoksijini: Ezinye izinto ezinokutya ezibuthathaka zeoksijini, ezinjengeevithani, njl njl. Njl.
Ukupakisha i-nitrogen akupheliseki i-microorganisms ekhoyo okanye yandise ubomi beshelufu yokutya kwi-Famiffine. Ezinye izinto, ezinjengokutya okutsha kokutya, ukuphatha ngokucocekileyo, ubushushu bokugcina, njl njl. Ke ngoko, xa usebenzisa ukupakisha i-nitrogen, kusafuneka ukudibanisa ukuphathwa ngokutya okuchanekileyo kunye neendlela zokugcina ukuqinisekisa ukhuseleko kunye nomgangatho wokutya.
Zeziphi iintlobo zokutya ezikwiphakheji ye-nitrogen ezifanelekileyo?
1. Inyama entsha kunye nenkukhu: Ukupakisha i-nitrojeni kwandisa ubomi benyama entsha kunye nenkukhu, njengenyama yenkomo, intlanzi, intlanzi, ilondoloze inyama kunye nokuncamathela inyama.
I-2. Iimveliso zaselwandle kunye neemveliso ze-aquitic: Ukupakisha i-nitrogen kunokwandisa ubomi beshelfokazi kunye neemveliso ze-aquatic, ezinje ngentlanzi, i-shrimp, njl. Njl.
I-3. Iziqhamo kunye nemifuno: Ukupakisha i-nitrogen kunokwandisa ubomi beshelpi kunye nemifuno, i-fures, i-tematis, i-times, i-times, i-temputer, i-fues kunye nexabiso lesondlo leziqhamo kunye nemifuno.
4. Ukutya okuphekiweyo kunye nokuqhutywa kwenkqubo kulungele zonke iintlobo zokutya okuphekiweyo kunye nokusetyenziswa kwenkqubo, iimveliso zenyama, iimveliso zenyama ye-Deli, inyamakazi, njl njl.
I-5. Amantongomane kunye neziqhamo ezomileyo: Ukupakisha i-nitrojeni kwandisa ubomi beshelufa kunye neziqhamo ezomileyo ezinjengee-walncion, iidiliya, ukugcina isarha, ukugcina isiqhamo esitsha kunye neziqhamo ezomileyo.
Ngaba ukupakisha i-nitrogen Ngaba nayiphi na ifuthe kwixabiso lesondlo lokutya?
Ukupakishwa kwemozulu yemozulu (imephu) ayinampembelelo encinci kwixabiso lesondlo, ikakhulu ngokudlulisela ubomi beshelufa yokutya ukugcina uzinzo luhlobo lwayo lwezakha-mzimba.
Nazi ezinye iindlela zeqhosha malunga nefuthe lokupakisha i-nitrojeni kwixabiso lesondlo:
1. Gcina izondlo: Ukupakisha i-nitrogen kunokucothisa indlela yokuphendula kwe-oxidation ekutyeni nasekunciphiseni inqanaba le-vitamins kunye nezinye izondlo. Oku kunceda ukugcina izondlo ekufumaneni ukutya okuzinzileyo kwaye kwandise ubomi beshels yayo.
2. Gcina ii-pigments kunye nemibala yendalo: Ezinye izinto zokutya zinemibala yendalo, njengaleyo ifunyenwe kwiziqhamo kunye nemifuno. Ukupakisha i-nitrojeni kunokunciphisa iziphumo zokuphendula kwe-oxidation kwezi pigments, ukugcina umbala kunye nokubonakala kokutya.
3. Gcina ingcambi kunye nokuthungwa kokutya: Ukupakisha i-nitrogen kunokugcina ukuthungwa kunye nokuncamathisela ukutya, ukuthintela ukutya kuko, ukuthathwa kwenkqubo yokupakisha. Oku kudlala indima ebalulekileyo ekugcineni incasa kunye nomgangatho wokutya okuthile.
Ithini isiphumo esithile sephakheji ye-nitrogen kwintanda kunye nokuthungwa kokutya?
1. Gcina ubugqwirha kunye nengqumbo: kwezinye zeepispy ezinje ngee-chips zetapile, iibhisi zenkukhu, inkukhu ethosiweyo, njl. Njl. Ngokunciphisa uxinzelelo lweoksijini ngaphakathi kwephakheji, ukupakisha i-nitrogen kunokucothisa indlela yokuphendula i-oxidation ngokutya, ukuthintela ukutya ekuthambekeni okanye ukuphulukana nentanda ye-crunnedy.
2. Gcina ubugwenxa kunye nesisa: Ukutya okuthile kwaye kukutya okuphekiweyo, njengokutya, iimveliso zobisi, iipali ze-nitrojeni zinceda ukuba zibaleke kwaye zithambekele. Ngokulawula iatmosfera ngaphakathi kwephakheji, ukupakisha i-nitrojeni kunokunciphisa ukwenziwa kwamanzi kunye nokuphendula kwe-oxidation yamanzi kwaye bagcine incasa yokutya.
3. Thintela uxinzelelo kunye notshintsho lwemilo: Ukupakisha i-nitrogen kunokukhusela ubume kunye nolwakhiwo lokutya ukuya kwinqanaba elithile. Ingawunciphisa umxholo weoksijini kwiphakheji kwaye unciphise impembelelo yeoksijini ekutyeni, ngokuthi ngokuthi kukuthintela ukutya okunyanzelwa, kuthathelwe phantsi kwinkqubo yokupakisha.
4. Gcina uzinzo lweSomlomo: Ukupakisha i-nitrojeni kunceda ukugcina uzinzo lokungcamla okutya. Ngokucothisa ukuphendula kwe-oxidation kunye nokukhula kwe-rabial ekutyeni, ukupakisha i-nitrogen kunokulibazisa i-spoilage kunye nokupheliswa komgangatho wokutya, ngaloo ndlela kugcinwa ngokungqinelana kunye nokuzinza kwencasa yokutya.
Pls mandazise imfuneko yakho, ndikulungele ukubonelela ngolwazi oluthe kratya.
