Dab tsi yog qhov tshiab-ua haujlwm ntawm lub tshuab nqus tsev ntim khoom?

Raws li peb txhua tus paub, deoxidization yog ib feem tseem ceeb ntawm lub tshuab nqus tsev ntim khoom. Lub luag haujlwm tseem ceeb ntawm lub tshuab nqus tsev yog tshem tawm cov pa oxygen kom pab tiv thaiv cov zaub mov tsis zoo. Lub hauv paus ntsiab lus kuj tseem yooj yim. Vim tias cov zaub mov mildew thiab lwj feem ntau yog tshwm sim los ntawm cov dej num ntawm cov kab mob, thiab feem ntau cov kab mob (xws li pwm thiab cov poov xab) xav tau oxygen kom ciaj sia. Lub tshuab nqus tsev ntim yog siv lub hauv paus ntsiab lus no txhawm rau rho tawm cov pa oxygen los ntawm lub hnab ntim khoom thiab cov khoom noj khoom haus, kom cov kab mob plam lawv "nyob ib puag ncig". (Faj seeb: Lub tshuab nqus tsev ntim tsis tuaj yeem cuam tshuam qhov kev loj hlob ntawm cov kab mob anaerobic thiab cov khoom noj khoom haus tsis zoo los ntawm cov tshuaj tiv thaiv enzyme, yog li nws kuj yuav tsum tau ua ke nrog lwm cov kev pabcuam, xws li kev cia txias, khov ceev, lub cev qhuav dej, kub kub. sterilization, irradiation sterilization, microwave sterilization, ntsev pickling, thiab lwm yam).
Ntxiv nrog rau inhibiting kev loj hlob thiab kev loj hlob ntawm cov kab mob, lwm yam tseem ceeb ntawm lub tshuab nqus tsev deoxidization yog los tiv thaiv cov zaub mov oxidation. Vim tias cov khoom noj muaj roj muaj ntau cov roj fatty acids tsis txaus, lawv raug oxidized los ntawm cov pa oxygen, ua rau cov zaub mov tsis zoo. Tsis tas li ntawd, oxidation kuj ua rau poob ntawm cov vitamin A thiab vitamin C, thiab cov khoom tsis ruaj khov hauv cov zaub mov pigments raug cuam tshuam los ntawm oxygen, ua rau cov xim tsaus dua. Yog li, deoxidization tuaj yeem tiv thaiv cov zaub mov tsis zoo thiab tswj nws cov xim, ntxhiab, saj thiab khoom noj muaj txiaj ntsig. Ntev npaum li lub tshuab nqus tsev me me tuaj yeem ua tiav ib qho kev nqus ntawm lub tshuab nqus tsev, nws kuj yog tib yam.
Lwm qhov tseem ceeb ntawm lub tshuab nqus tsev ntim khoom yog kev nce nqi. Ntxiv nrog rau qhov deoxygenation thiab kev ruaj ntseg zoo ntawm lub tshuab nqus tsev ntim, lub luag haujlwm tseem ceeb ntawm lub tshuab nqus tsev nqus tau ntim yog compression tsis kam, roj tsis kam thiab khaws cia, uas tuaj yeem ua tau zoo dua qub xim, tsw qab, saj, zoo li thiab khoom noj muaj txiaj ntsig ntawm zaub mov. ntev. Tsis tas li ntawd, lub tshuab nqus tsev ntim tsis haum rau ntau yam khoom noj, tab sis lub tshuab nqus tsev nqus tsev vacuum yuav tsum tau siv. Xws li cov khoom noj uas tsis muaj zog, cov zaub mov yooj yim rau agglomerate, cov khoom noj yooj yim rau deform thiab roj, cov khoom noj uas muaj cov npoo ntse lossis cov tawv tawv siab uas yuav puncture lub hnab ntim khoom, thiab lwm yam. huab cua siab nyob rau hauv lub hnab ntim khoom muaj zog tshaj qhov siab ntawm atmospheric sab nraum lub hnab ntim khoom, uas tuaj yeem tiv thaiv cov zaub mov kom tsis txhob raug crushed thiab deformed nyob rau hauv lub siab, tsis muaj kev cuam tshuam rau cov tsos ntawm lub hnab ntim khoom thiab luam ntawv thiab kho kom zoo nkauj.
Lub tshuab nqus tsev ntim ntim yog ntim nrog nitrogen, carbon dioxide, oxygen ib qho roj lossis sib tov ntawm 2-3 gases tom qab nqus tsev. Nitrogen yog ib qho roj inert, uas ua lub luag haujlwm puv thiab ua kom lub siab zoo hauv lub hnab kom tsis txhob muaj cua sab nraum lub hnab nkag mus rau hauv lub hnab, yog li tiv thaiv cov khoom noj. Cov pa roj carbon oxide tuaj yeem yaj hauv ntau hom roj lossis dej los tsim cov pa roj carbonic acid tsis muaj zog, thiab muaj cov haujlwm ntawm inhibiting microorganisms xws li pwm thiab cov kab mob lwj. Oxygen tuaj yeem cuam tshuam kev loj hlob thiab kev loj hlob ntawm cov kab mob anaerobic, tswj qhov tshiab thiab xim ntawm cov txiv hmab txiv ntoo thiab zaub, thiab cov pa oxygen siab tuaj yeem ua kom cov nqaij tshiab ci.
