Emaphaketheni e-nitrogen, ukwakheka komoya ngaphakathi kwesitsha kuyalungiswa, ngokuvamile ngokujova i-nitrogen esitsheni ukuze kushintshwe noma kuncishiswe ukugcwala komoyampilo.Inhloso yalokhu ukwehlisa ijubane ukusabela kwe-oxidation kanye nokukhula kwe-microbial, ngaleyo ndlela andise impilo yeshalofu yokudla.
Umgomo wokupakishwa kwe-nitrogen ukunciphisa ukugcwala komoyampilo ekudleni ngokususa noma ukunciphisa ukuba khona komoyampilo, ngaleyo ndlela kwehliswe inqubo yokubola kokudla.Inayitrojeni igesi engasebenzi ngokwekhemikhali engahlangani nokudla futhi ayithinti ukunambitheka nokuthungwa kokudla.
Ngokupakishwa kwe-nitrogen, ukudla kungagcinwa kukusha futhi kunambitheka kahle, futhi ukuwohloka kwezinga lokudla kungancipha.Lobu buchwepheshe bokupakisha busetshenziswa kakhulu emikhiqizweni yokudla ehlukahlukene njengenyama, izithelo, imifino, izibiliboco, imikhiqizo yobisi namakhekhe.
Kumele kuqashelwe ukuthi ukupakishwa kwe-nitrogen akubhubhisi amabhaktheriya noma ama-microorganisms asevele ekhona ekudleni, kubambezela ukukhula kwawo kanye nokonakala ngokulungisa umkhathi ozungezile.Ngakho-ke, lapho usebenzisa ukupakishwa kwe-nitrogen, kusadingeka ukunaka ukuphathwa okuhlanzekile kokudla kanye nezimo ezifanele zokugcina ukuze kuqinisekiswe ukuphepha kanye nekhwalithi yokudla.
Uyini umthelela othize wokupakishwa kwenitrogen eshalofini lempilo yokudla?
1. Vimbela ukusabela kwe-oxidation: ukupakishwa kwe-nitrogen kubambezela ukusabela kwe-oxidation ngokunciphisa ukugcwala komoyampilo ephaketheni nokunciphisa ukuthintana komoyampilo ekudleni.Ukusabela kwe-oxidation kungenye yezimbangela eziyinhloko zokonakala kokudla kanye nokuwohloka kwekhwalithi, njenge-fat oxidation kanye noshintsho lwe-pigment ekudleni.Ngokuvimbela ukusabela kwe-oxidation, ukupakishwa kwe-nitrogen kungandisa impilo yeshalofu yokudla.
2. Lawula ukukhula kwe-microbial: Ukupakishwa kwe-nitrogen kunganciphisa inani le-oksijini ngaphakathi kwephakheji, ngaleyo ndlela kunciphise ukukhula kwama-microorganisms afana namagciwane, isikhunta kanye nemvubelo.Lawa ma-microorganisms angenye yezinto eziyinhloko eziholela ekulimaleni nokudla.Ngokulawula ukukhula kwe-microbial, ukupakishwa kwe-nitrogen kusiza ukunweba impilo yeshalofu yokudla.
3. Gcina ukwakheka nokuthungwa kokudla: Ukupakishwa kwe-nitrogen kungagcina ukwakheka nokuthungwa kokudla, kuvimbele ukudla ukuthi kungacindezelwa, kugogeke noma kuthambe ngesikhathi sokupakisha.Lokhu kudlala indima ebalulekile ekugcineni ukubukeka, ukuthungwa kanye nekhwalithi yokudla okuthile okufana nokudla oku-crispy, amakhekhe, njll.
4. Vimbela ukuwohloka kwezinto ezizwela umoya-mpilo: Okunye ukudla kuqukethe izinto ezizwela umoya-mpilo, njengamavithamini, ama-anthocyanins, njll. Ukupakishwa kwe-nitrogen kunganciphisa ukugcwala komoyampilo ekudleni futhi kunciphise izinga le-oxidation lalezi zinto, ngaleyo ndlela kugcine imisoco. futhi umbala ekudleni.
Ukupakishwa kwe-nitrogen akususi ama-microorganisms akhona ngaphambili noma andise impilo yeshalofu yokudla ibe ingunaphakade.Ezinye izici, njengokusha kokudla, ukuphathwa kwenhlanzeko, izinga lokushisa lokugcina, njll., zisenomthelela obalulekile empilweni yeshalofu.Ngakho-ke, lapho usebenzisa ukupakishwa kwe-nitrogen, kusadingeka ukuhlanganisa ukuphatha ukudla okulungile nezindlela zokugcina ukuze kuqinisekiswe ukuphepha kanye nekhwalithi yokudla.
Yiziphi izinhlobo zokudla ezifanele ukupakishwa kwe-nitrogen?
1. Inyama entsha nezinkukhu: Ukupakishwa kwe-nitrogen kwandisa isikhathi seshelufu senyama nezinkukhu ezintsha, njengenyama yenkomo, ingulube, iwundlu, inkukhu, inhlanzi, njll. Kuvimbela ukukhishwa kwe-oxidation nokukhula kwamagciwane, ukugcina ukuthamba nokunambitha kwenyama.
2. Imikhiqizo yasolwandle nemikhiqizo yasemanzini: Ukupakishwa kwe-nitrogen kungandisa isikhathi seshelufu sokudla kwasolwandle kanye nemikhiqizo yasemanzini, njengezinhlanzi, izimfanzi, i-shellfish, inkalankala, njll. Kunciphisa inqubo yokona futhi kugcine ubusha kanye nokunambitheka kokudla kwasolwandle.
3. Izithelo nemifino: Ukupakishwa kwe-nitrogen kungandisa isikhathi seshalofu sezithelo nemifino, njengama-apula, amapheya, ama-strawberry, amagilebhisi, utamatisi, ulethisi, njll. Yehlisa i-oxidation nokukhula kwe-microbial, futhi igcina umbala, ukunambitheka kanye nokudla okunomsoco. wezithelo nemifino.
4. Ukudla okuphekiwe nokucutshungulwayo: I-nitrogen emaphaketheni ifanele zonke izinhlobo zokudla okuphekiwe nokugaywe, okufana nenyama, amasoseji, imikhiqizo yenyama ebili, imikhiqizo yobisi, isinkwa, amakhekhe, njll. Inganweba isikhathi seshalofu salokhu kudla futhi silondoloze ukuthungwa nokunambitha kwabo.
5. Amantongomane nezithelo ezomisiwe: Ukupakishwa kwe-nitrogen kwandisa impilo yeshalofu yamantongomane nezithelo ezomisiwe njengama-walnuts, ama-alimondi, ama-cashews, ama-raisin omisiwe, njll. Yehlisa i-oxidation kanye ne-rancidity, igcina ubusha kanye nokunambitheka kwamantongomane nezithelo ezomisiwe.
Ingabe ukupakishwa kwe-nitrogen kunawo umthelela enanini lokudla okunomsoco?
I-Modified Atmosphere Packaging (MAP) inomthelela omncane enanini lomsoco lokudla, ikakhulukazi ngokwelula isikhathi seshelufu sokudla ukuze kugcinwe ukuqina kwakho okulinganiselwe kwemisoco.
Nazi ezinye izinto ezibalulekile ezithathwayo mayelana nomthelela wokupakishwa kwe-nitrogen enanini lokudla okunomsoco:
1. Gcina izakhi: Ukupakishwa kwe-nitrogen kunganciphisa ukusabela kwe-oxidation ekudleni futhi kunciphise izinga le-oxidation lamavithamini nezinye izakhi.Lokhu kusiza ukugcina imisoco esekudleni izinzile futhi yandise isikhathi sakho seshelufu.
2. Gcina umbala nemibala yemvelo: Okunye ukudla kunemibala yemvelo, njengaleyo etholakala ezithelweni nasemifino.Ukupakishwa kwe-nitrogen kunganciphisa imiphumela yokusabela kwe-oxidation kulezi mibala, kugcinwe umbala nokubukeka kokudla.
3. Gcina ukunambitheka nokuthungwa kokudla: Ukupakishwa kwe-nitrogen kungagcina ukuthungwa kanye nokunambitheka kokudla, kuvimbele ukudla ukuthi kucindezelwe, ukonakala noma ukuthamba ngesikhathi sokupakisha.Lokhu kudlala indima ebalulekile ekugcineni ukunambitheka kanye nekhwalithi yokudla okuthile.
Uyini umphumela othize wokupakishwa kwe-nitrogen enambithekeni nasekuthuthweni kokudla?
1. Gcina ukucwazimula nokucwebezela: Kokunye ukudla okucwebezelayo okufana namashibhisi amazambane, amabhisikidi, inkukhu ethosiwe e-crispy, njll., ukupakishwa kwe-nitrogen kungakugcina kucwebile futhi kucwebile.Ngokunciphisa ukugcwala komoyampilo ngaphakathi kwephakeji, ukupakishwa kwe-nitrogen kunganciphisa ukusabela kwe-oxidation ekudleni, kuvimbele ukudla ukuthi kuthambe noma kulahlekelwe ukunambitheka kwakho okumuncu.
2. Gcina umswakama nokuthambile: Ngokudla okuthile okumanzi nokuthambile, njengemikhiqizo yenyama ephekiwe, imikhiqizo yobisi, amakhekhe, njll., ukupakishwa kwe-nitrogen kusiza ukukugcina kunomswakama futhi kuthambile.Ngokulawula umkhathi ngaphakathi kwephakeji, ukupakishwa kwe-nitrogen kunganciphisa ukuhwamuka nokusabela kwe-oxidation kwamanzi futhi kugcine ukunambitheka okumanzi kokudla.
3. Vimbela ukucindezelwa nokushintsha kwesimo: Ukupakishwa kwe-nitrogen kungavikela ukwakheka nokwakheka kokudla ngokwezinga elithile.Inganciphisa okuqukethwe komoyampilo ephaketheni futhi inciphise umthelela komoyampilo ekudleni, ngaleyo ndlela igweme ukudla ukucindezelwa, ukonakala noma ukuthambisa ngesikhathi sokupakisha.
4. Gcina ukuzinza kwe-mouthfeel: Ukufakwa kwe-nitrogen kusiza ukugcina ukuzinza kokunambitheka kokudla.Ngokunciphisa ukusabela kwe-oxidation kanye nokukhula kwe-microbial ekudleni, ukupakishwa kwe-nitrogen kungabambezela ukubola kanye nokuwohloka kwekhwalithi yokudla, ngaleyo ndlela kugcinwe ukungaguquguquki nokuzinza kokunambitha kokudla.
Pls ungazise izidingo zakho ezithile, ngizimisele ukukunikeza ulwazi olwengeziwe.
