Mukutakura nitrogen, kuumbwa kwemhepo mukati memudziyo kunogadziriswa, kazhinji nekupinza nitrogen mumudziyo kuti utsive kana kuderedza kuwanda kweokisijeni.Chinangwa cheizvi ndechekudzikisira kuita kweoxidation uye kukura kwehutachiona, nekudaro kuwedzera hupenyu hwesherufu yechikafu.
Nheyo yenitrogen kurongedza ndeyekudzikisa huwandu hweokisijeni muchikafu nekubvisa kana kudzikisa huvepo hweokisijeni, nekudaro ichidzikisira kuparara kwechikafu.Nitrogen igasi inert isingabatanidzi nemakemikari nechikafu uye isingakanganise kunaka nekunaka kwechikafu.
Nekurongedzerwa kwenitrogen, chikafu chinogona kuchengetwa chiri chitsva uye chinonaka, uye kuparara kwemhando yezvokudya kunogona kudzikiswa.Iyi tekinoroji yekurongedza inoshandiswa zvakanyanya mumhando dzakasiyana dzezvigadzirwa zvekudya zvakaita senyama, michero, miriwo, delicatessen, zvigadzirwa zvemukaka nemakeke.
Izvo zvinofanirwa kucherechedzwa kuti nitrogen packaging haiparadzi mabhakitiriya kana tupukanana turipo mune chikafu, inongononoka kukura kwayo uye kuparara nekugadzirisa ambient atmosphere.Naizvozvo, kana uchishandisa nitrogen kurongedza, zvichiri kudikanwa kuterera kune hutsanana kubata kwechikafu uye kwakakodzera kuchengetedza mamiriro kuti uve nechokwadi chekuchengetedza uye kunaka kwechikafu.
Ndeipi chaiyo kukanganisa kwenitrogen kurongedza pasherufu yehupenyu hwechikafu?
1. Inhibit oxidation reaction: nitrogen packaging inononoka kuita oxidation kuburikidza nekuderedza huwandu hweokisijeni mupakiti uye kuderedza kusangana kweokisijeni muchikafu.Oxidation reaction ndechimwe chezvikonzero zvikuru zvekuparara kwechikafu uye kuparara kwemhando, senge mafuta oxidation uye shanduko yepigment muchikafu.Nekudzivisa oxidation maitiro, nitrogen kurongedza inogona kuwedzera hupenyu hwesherufu yechikafu.
2. Kudzora kukura kwe microbial: Nitrogen packaging inogona kuderedza huwandu hweokisijeni mukati mehomwe, nokudaro kuderedza kukura kwehutachiona hwakadai sebhakitiriya, mold uye mbiriso.Aya ma microorganisms ndechimwe chezvinhu zvikuru zvinotungamira mukuparara kwechikafu uye kuparara.Nekudzora kukura kwehutachiona, nitrogen kurongedza kunobatsira kuwedzera hupenyu hwesherufu yechikafu.
3. Chengetedza chimiro chekudya uye chimiro: Nitrogen packaging inogona kuchengetedza chimiro uye chimiro chekudya, kudzivirira chikafu kubva pakumanikidzwa, kuremara kana kupfava panguva yekurongedza.Izvi zvinoita basa rakakosha mukuchengetedza chitarisiko, magadzirirwo uye mhando yezvimwe zvikafu zvakaita secrispy foods, pastries, etc.
4. Kudzivirira kuparara kwezvinhu zvinonzwa okisijeni: Zvimwe zvokudya zvine zvinhu zvinonzwa okisijeni, zvakadai sevhitamini, anthocyanins, nezvimwewo. Nitrogen packaging inogona kuderedza kuwanda kweokisijeni muzvokudya uye kuderedza kuwanda kweoxidation yezvinhu izvi, nokudaro kuchengetedza kudya. uye ruvara muzvokudya.
Nitrogen packaging haibvisi ma microorganisms aripo kana kuwedzera hupenyu hwesherufu yezvokudya kusvika kusingagumi.Zvimwe zvinhu, senge kutsva kwechikafu, kubata hutsanana, tembiricha yekuchengetera, nezvimwe, zvichine kukosha kwakakosha pahupenyu hwesherufu.Naizvozvo, kana uchishandisa nitrogen kurongedza, zvichiri kudikanwa kusanganisa kwakaringana mabatiro echikafu uye nzira dzekuchengetedza kuve nechokwadi chekuchengetedza uye kunaka kwechikafu.
Ndeapi marudzi echikafu akakodzera nitrogen kurongedza?
1. Nyama itsva nehuku: Nitrogen packaging inowedzera hupenyu hwesherufu yenyama itsva uye huku, zvakadai semombe, nyama yenguruve, gwayana, huku, hove, nezvimwewo Inodzivirira oxidation uye kukura kwebhakitiriya, kuchengetedza unyoro uye kuravira kwenyama.
2. Zvokudya zvegungwa uye zvigadzirwa zvemumvura: nitrogen packaging inogona kuwedzera hupenyu hwesherufu yezvokudya zvegungwa uye zvemumvura, zvakadai sehove, shrimp, shellfish, crab, nezvimwewo. Inoderedza kuparara uye inochengetedza kutsva uye kuravira kwezvokudya zvegungwa.
3. Zvibereko nemiriwo: Nitrogen packaging inogona kuwedzera hupenyu hwesherufu yemichero nemiriwo, semaapuro, mapeari, sitirobheri, mazambiringa, matomatisi, lettuce, nezvimwewo. Inoderedza oxidation uye kukura kwe microbial, uye inochengetedza ruvara, kuravira uye kukosha kwekudya. zvemichero nemiriwo.
4. Zvokudya zvakabikwa uye zvakagadziriswa: Nitrogen packaging inokodzera marudzi ose ezvokudya zvakabikwa uye zvakagadziriswa, zvakadai sehamu, soseji, zvigadzirwa zvenyama, zvigadzirwa zvemukaka, chingwa, mapeji, nezvimwewo. Inogona kuwedzera hupenyu hwesherufu yezvokudya izvi uye kuchengetedza. magadzirirwo avo uye kuravira.
5. Nzungu uye michero yakaomeswa: Nitrogen packaging inowedzera hupenyu hwesherufu yemiti nemichero yakaomeswa yakadai semarnuts, almonds, cashews, mazambiringa akaomeswa, etc. Inoderedza oxidation uye rancidity, kuchengetedza kutsva uye kunakidza kwemiti nemichero yakaomeswa.
Ko nitrogen kurongedza kune chero mhedzisiro paukoshi hwekudya kwechikafu?
Modified Atmosphere Packaging (MAP) ine zvishoma zvinokanganisa kukosha kwekudya kwekudya, kunyanya nekuwedzera hupenyu hwesherufu yechikafu kuchengetedza kugadzikana kwayo kwekudya.
Heano mamwe akakosha ekutora nezve kukanganisa kwe nitrogen packaging pane inovaka kukosha kwechikafu:
1. Chengetedza kudya: Nitrogen packaging inogona kuderedza kushandiswa kweoxidation muzvokudya uye kuderedza huwandu hwehutachiwana hwevhithamini nezvimwe zvinovaka muviri.Izvi zvinobatsira kuchengetedza chikafu chiri muchikafu chakagadzikana uye kuwedzera hupenyu hwacho hwesherufu.
2. Chengetedza pigment uye mavara echisikigo: Zvimwe zvekudya zvine mavara echisikigo, akadai seanowanikwa mumichero nemiriwo.Nitrogen packaging inogona kuderedza mhedzisiro yeoxidation maitiro pane aya pigment, kuchengetedza ruvara uye kutaridzika kwechikafu.
3. Chengetedza kuravira uye kugadzirwa kwechikafu: Nitrogen packaging inogona kuchengetedza magadzirirwo uye kuravira kwechikafu, kudzivirira chikafu kubva pakumanikidzwa, kuremara kana kupfava panguva yekurongedza.Izvi zvinoita basa rakakosha mukuchengetedza kunaka uye kunaka kwezvimwe zvekudya.
Ndeipi chaiyo mhedzisiro yekurongedza nitrogen pane kuravira uye kuumbwa kwechikafu?
1. Chengetedza crispiness uye crispiness: Kune zvimwe crispy chikafu chakadai sembatatisi machipisi, mabhisikiti, yakakangwa crispy huku, nezvimwewo, nitrogen packaging inogona kuzvichengeta crispy uye crispy.Nekudzikisa huwandu hweokisijeni mukati mepakeji, nitrogen kurongedza inogona kudzikamisa maitiro eiyo oxidation muchikafu, kudzivirira chikafu kuti chisapfava kana kurasikirwa nekuravira kwayo.
2. Chengetedza kunyorova uye kupfava: Kune zvimwe zvekudya zvakanyorova uye zvinyoro, zvakadai sezvigadzirwa zvenyama yakabikwa, zvigadzirwa zvemukaka, makeke, nezvimwewo, nitrogen packaging inobatsira kuti zvirambe zvakanyorova uye zvinyoro.Nekudzora mamiriro ekunze mukati mepakeji, nitrogen kurongedza inogona kuderedza kubuda uye oxidation maitiro emvura uye kuchengetedza kunyorova kuravira kwechikafu.
3. Kudzivirira kudzvinyirira uye kuchinja kwechimiro: Nitrogen packaging inogona kuchengetedza chimiro uye chimiro chekudya kune imwe nhanho.Inogona kuderedza iyo okisijeni yemukati mupakeji uye kuderedza kukanganiswa kweokisijeni pachikafu, nekudaro ichidzivirira chikafu kudzvinyirirwa, kuremara kana kupfaviswa panguva yekurongedza.
4. Chengetedza kugadzikana kwemuromo wemuromo: Nitrogen packaging inobatsira kuchengetedza kugadzikana kwekunaka kwezvokudya.Nekudzikamisa maitiro eiyo oxidation uye kukura kwemicrobial muchikafu, nitrogen kurongedza kunogona kunonoka kuparara uye kuparara kwemhando yechikafu, nekudaro kuchengetedza kuwirirana uye kugadzikana kwekuravira kwechikafu.
Pls ndizivise zvaunoda chaizvo, ndinoda kupa rumwe ruzivo.
