Hauv kev ntim cov nitrogen, qhov sib xyaw ntawm huab cua hauv lub thawv yog hloov kho, feem ntau yog los ntawm kev txhaj tshuaj nitrogen rau hauv lub thawv los hloov lossis txo qhov concentration ntawm oxygen.Lub hom phiaj ntawm qhov no yog kom qeeb oxidation cov tshuaj tiv thaiv thiab microbial kev loj hlob, yog li ncua lub txee lub neej ntawm cov zaub mov.
Lub hauv paus ntsiab lus ntawm nitrogen ntim yog txo cov pa oxygen hauv cov zaub mov los ntawm kev tshem tawm lossis txo qhov muaj cov pa oxygen, yog li ua kom qeeb ntawm cov khoom noj khoom haus.Nitrogen yog cov roj inert uas tsis muaj tshuaj lom nrog cov zaub mov thiab tsis cuam tshuam rau qhov tsw thiab kev ntxhib los mos ntawm cov khoom noj.
Nrog cov ntim nitrogen, cov zaub mov tuaj yeem khaws cia tshiab thiab saj zoo, thiab cov zaub mov tsis zoo tuaj yeem txo qis.Lub tshuab ntim khoom no tau siv dav hauv ntau yam khoom noj xws li nqaij, txiv hmab txiv ntoo, zaub, delicatessen, khoom noj siv mis thiab pastries.
Nws yuav tsum tau muab sau tseg tias nitrogen ntim tsis rhuav tshem cov kab mob los yog kab mob uas twb muaj nyob rau hauv cov zaub mov, nws tsuas yog ncua nws txoj kev loj hlob thiab spoilage los ntawm kev kho lub ambient cua.Yog li ntawd, thaum siv cov ntim ntim nitrogen, nws tseem yuav tsum tau ua tib zoo saib xyuas kev noj qab haus huv ntawm cov zaub mov thiab kev cia khoom kom zoo kom muaj kev nyab xeeb thiab zoo ntawm cov zaub mov.
Dab tsi yog qhov cuam tshuam tshwj xeeb ntawm ntim nitrogen rau lub txee lub neej ntawm cov zaub mov?
1. Inhibit oxidation cov tshuaj tiv thaiv: nitrogen ntim qeeb cov tshuaj tiv thaiv oxidation los ntawm kev txo cov pa oxygen concentration hauv pob thiab txo cov pa oxygen hauv cov zaub mov.Oxidation cov tshuaj tiv thaiv yog ib qho tseem ceeb ua rau cov zaub mov lwj thiab degradation zoo, xws li roj oxidation thiab pigment hloov hauv cov zaub mov.Los ntawm inhibiting oxidation cov tshuaj tiv thaiv, nitrogen ntim tuaj yeem txuas lub txee lub neej ntawm cov zaub mov.
2. Tswj kev loj hlob ntawm microbial: ntim nitrogen tuaj yeem txo cov pa oxygen hauv pob, yog li txwv kev loj hlob ntawm cov kab mob xws li kab mob, pwm thiab cov poov xab.Cov kab mob no yog ib qho ntawm cov khoom tseem ceeb uas ua rau cov zaub mov tsis zoo thiab lwj.Los ntawm kev tswj hwm microbial kev loj hlob, ntim nitrogen pab txuas ntxiv lub txee lub neej ntawm cov zaub mov.
3. Khaws cov qauv khoom noj thiab kev ntxhib los mos: ntim nitrogen tuaj yeem tswj cov qauv thiab kev ntxhib los mos ntawm cov khoom noj, tiv thaiv cov khoom noj los ntawm compressed, deformed lossis softened thaum lub sij hawm ntim khoom.Qhov no ua lub luag haujlwm tseem ceeb hauv kev saib xyuas cov tsos, kev ntxhib los mos thiab zoo ntawm qee yam khoom noj xws li cov khoom noj crispy, pastries, thiab lwm yam.
4. Tiv thaiv kom tsis txhob degradation ntawm cov pa oxygen rhiab heev: Qee cov khoom noj muaj cov pa oxygen, xws li cov vitamins, anthocyanins, thiab lwm yam. Nitrogen ntim tuaj yeem txo qhov concentration ntawm oxygen hauv cov zaub mov thiab txo cov oxidation ntawm cov khoom no, yog li tswj cov as-ham. thiab xim hauv cov zaub mov.
Nitrogen ntim tsis tshem tawm cov kab mob uas twb muaj lawm ua ntej lossis txuas lub txee lub neej ntawm cov zaub mov mus rau qhov kawg.Lwm yam, xws li cov khoom noj tshiab, kev tu cev, kev khaws cia kub, thiab lwm yam, tseem muaj feem cuam tshuam rau lub neej txee.Yog li ntawd, thaum siv cov ntim ntim nitrogen, nws tseem yuav tsum tau muab cov khoom noj kom raug thiab kev khaws cia kom muaj kev nyab xeeb thiab zoo ntawm cov zaub mov.
Cov khoom noj dab tsi yog cov ntim ntim nitrogen haum rau?
1. Cov nqaij tshiab thiab nqaij qaib: Cov khoom ntim nitrogen txuas ntxiv lub neej ntawm cov nqaij tshiab thiab nqaij qaib, xws li nqaij nyug, nqaij npuas, yaj, nqaij qaib, ntses, thiab lwm yam. Nws tiv thaiv oxidation thiab kab mob loj hlob, tswj qhov muag thiab saj ntawm cov nqaij.
2. Cov khoom noj nqaij nruab deg thiab cov dej hauv dej: ntim cov nitrogen tuaj yeem txuas ntxiv lub neej ntawm cov nqaij nruab deg thiab cov khoom hauv dej, xws li ntses, cws, shellfish, roob ris, thiab lwm yam. Nws ua rau cov txheej txheem lwj thiab ua kom cov nqaij nruab deg tshiab thiab saj.
3. Txiv hmab txiv ntoo thiab zaub: ntim nitrogen tuaj yeem txuas lub neej txee ntawm cov txiv hmab txiv ntoo thiab zaub, xws li txiv apples, pears, strawberries, txiv hmab txiv ntoo, txiv lws suav, lettuce, thiab lwm yam. Nws txo cov oxidation thiab microbial kev loj hlob, thiab tswj cov xim, saj thiab khoom noj muaj txiaj ntsig. ntawm txiv hmab txiv ntoo thiab zaub.
4. Cov khoom noj ua noj thiab ua tiav: Cov ntim ntim nitrogen yog tsim rau txhua yam khoom noj uas siav thiab ua tiav, xws li nqaij npua, hnyuv ntxwm, deli nqaij, cov khoom noj siv mis, qhob cij, pastries, thiab lwm yam. Nws tuaj yeem txuas lub txee lub neej ntawm cov khoom noj no thiab tswj tau. lawv kev ntxhib los mos thiab saj.
5. Cov txiv ntoo thiab txiv hmab txiv ntoo qhuav: Cov ntim ntim nitrogen txuas ntxiv lub neej txee ntawm cov txiv ntoo thiab cov txiv hmab txiv ntoo qhuav xws li walnuts, almonds, cashews, raisins, thiab lwm yam. Nws slows oxidation thiab rancidity, tswj lub freshness thiab tsw ntawm txiv ntseej thiab txiv hmab txiv ntoo qhuav.
Lub ntim nitrogen puas muaj kev cuam tshuam rau cov khoom noj muaj txiaj ntsig?
Modified Atmosphere Packaging (MAP) muaj kev cuam tshuam me ntsis rau cov khoom noj muaj txiaj ntsig ntawm cov zaub mov, feem ntau yog los ntawm kev ncua lub txee lub neej ntawm cov zaub mov kom tswj tau nws cov txheeb ze ruaj khov ntawm cov as-ham.
Nov yog qee cov lus qhia tseem ceeb txog qhov cuam tshuam ntawm cov ntim nitrogen ntawm cov khoom noj muaj txiaj ntsig zoo:
1. Tswj cov as-ham: ntim nitrogen tuaj yeem ua rau cov tshuaj tiv thaiv oxidation hauv cov zaub mov thiab txo cov oxidation ntawm cov vitamins thiab lwm cov as-ham.Qhov no pab ua kom cov as-ham hauv cov zaub mov ruaj khov thiab txuas ntxiv nws lub txee lub neej.
2. Khaws cov pigments thiab cov xim ntuj: Qee cov khoom noj muaj xim ntuj, xws li cov txiv hmab txiv ntoo thiab zaub.Nitrogen ntim tuaj yeem txo cov teebmeem oxidation ntawm cov pigments, tswj cov xim thiab cov tsos ntawm cov zaub mov.
3. Khaws cov saj thiab kev ntxhib los mos ntawm cov khoom noj: Nitrogen ntim tuaj yeem tswj qhov kev ntxhib los mos thiab saj ntawm cov khoom noj, tiv thaiv cov khoom noj los ntawm compressed, deformed lossis softened thaum lub sij hawm ntim khoom.Qhov no ua lub luag haujlwm tseem ceeb hauv kev tswj qhov tsw thiab zoo ntawm qee yam khoom noj.
Dab tsi yog qhov tshwj xeeb ntawm cov ntim nitrogen rau ntawm saj thiab kev ntxhib los mos ntawm cov khoom noj?
1. Ua kom lub ntsej muag ci thiab crispiness: Rau qee cov khoom noj crispy xws li qos yaj ywm chips, biscuits, kib crispy nqaij qaib, thiab lwm yam., nitrogen ntim yuav ua kom lawv nkig thiab crispy.Los ntawm kev txo cov pa oxygen nyob rau hauv lub pob, ntim nitrogen tuaj yeem ua rau cov tshuaj tiv thaiv oxidation hauv cov zaub mov, tiv thaiv cov zaub mov los ntawm softening los yog poob nws crunchy saj.
2. Khaws cov dej noo thiab rhiab: Rau qee yam khoom noj uas ntub thiab sib tw, xws li cov nqaij siav, cov khoom noj siv mis, pastries, thiab lwm yam, cov ntim nitrogen pab kom lawv ntub thiab sib tw.Los ntawm kev tswj cov huab cua hauv lub pob, ntim nitrogen tuaj yeem txo cov evaporation thiab oxidation cov tshuaj tiv thaiv ntawm cov dej thiab tswj cov khoom noj khoom haus.
3. Tiv thaiv compression thiab cov duab hloov pauv: ntim nitrogen tuaj yeem tiv thaiv cov duab thiab qauv ntawm cov khoom noj rau qee yam.Nws tuaj yeem txo cov ntsiab lus ntawm cov pa oxygen hauv pob thiab txo qhov cuam tshuam ntawm cov pa oxygen ntawm cov khoom noj, yog li zam kom tsis txhob cov zaub mov raug compressed, deformed lossis softened thaum lub sij hawm ntim khoom.
4. Ua kom ruaj khov ntawm qhov ncauj qhov ntswg: ntim nitrogen pab tswj kev ruaj ntseg ntawm cov khoom noj.Los ntawm kev ua kom qeeb ntawm cov tshuaj tiv thaiv oxidation thiab kev loj hlob ntawm microbial hauv cov zaub mov, ntim nitrogen tuaj yeem ncua kev lwj thiab degradation zoo ntawm cov zaub mov, yog li tswj qhov sib xws thiab ruaj khov ntawm cov khoom noj.
Pls qhia rau kuv paub koj qhov kev xav tau tshwj xeeb, Kuv txaus siab muab cov ntaub ntawv ntxiv.
