1. Txheej txheem cej luam ntawm cov ntawv ntim khoom ntse
Nyob rau hauv cov txheej txheem ntim khoom, chav ua haujlwm huv huv yog tsawg kawg ib txhiab-theem chav huv. Txawm li cas los xij, thaum xaiv cov khoom ntim thiab kev ua haujlwm, peb kuj yuav tsum tau them sai sai rau cov teebmeem ntawm kev tiv thaiv corrosion thiab ya raws.
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev ntim khoom noj ntse (qhov ntsuas qhov ntsuas, ntim cov khoom ntim, lub xov tooj cua zaus txheeb xyuas lub ntim) yog ntau thiab siv dav hauv kev ntim khoom noj. Kev siv cov thev naus laus zis ntim khoom no ua rau tib neeg tuaj yeem saib ncaj qha txog kev hloov pauv ntawm cov zaub mov hauv lub ntim. Piv txwv li, qhov ntsuas qhov ntim tuaj yeem cuam tshuam cov ntaub ntawv sab hauv ntawm lub ntim rau cov neeg siv khoom raws sijhawm raws li qhov kev hloov pauv ntawm qhov kub, acidity, huab cua to thiab lwm yam ntsuas hauv lub ntim, kom cov neeg siv khoom nkag siab txog cov khoom noj tshiab.
Lub ntim sensor yog cog cov khoom siv hluav taws xob hauv cov khoom ntim rau kev kuaj pom, thiab hloov ib daim ntawv ntawm cov teeb liab mus rau lwm daim ntawv. Cov thev naus laus zis no tuaj yeem siv rau kev saib xyuas cov kab mob microbial spoilage hauv cov zaub mov, thiab tuaj yeem saib xyuas cov kev hloov pauv ntawm cov kab mob hauv ntim hauv lub sijhawm. Nws muaj feem xyuam rau lub neej txee ntawm cov khoom noj prepackaged.
2. Txheej txheem cej luam ntawm daim ntawv thov ntim tshuaj tua kab mob
Khoom noj khoom haus yog nplua nuj nyob rau hauv cov as-ham, thiab nws yog ib qho yooj yim rau tu cov kab mob, ua rau cov zaub mov spoilage. Kev ntim tshuaj tua kab mob tuaj yeem ntxiv cov tshuaj tua kab mob tsis muaj tshuaj tua kab mob rau cov khoom ntim, thiab maj mam tso cov tshuaj tua kab mob hauv cov khoom ntim khoom thaum lub sijhawm khaws cia, yog li ua kom muaj cov kab mob tua kab mob.
Tam sim no, cov ntim tshuaj tua kab mob feem ntau suav nrog cov ntim tshuaj tua kab mob inorganic, cov ntim tshuaj tua kab mob organic thiab cov ntim tshuaj tua kab mob ntuj. Ntawm lawv, inorganic antibacterial ntim xws li nano-silver thiab nano-oxide yog dav siv vim nws cov kab mob dav dav, cov nyhuv antibacterial zoo, thiab lub sijhawm siv tau ntev.
Organic antibacterial ntim sawv cev los ntawm qhov hnyav molecular antibacterial quaternary ammonium ntsev thiab siab molecular hnyav organic antibacterial tus neeg sawv cev tuaj yeem cuam tshuam cov synthesis ntawm cov kab mob protein / cell phab ntsa, lossis cuam tshuam nrog cov kab mob tsis zoo thiab cov cell membranes.
Natural antibacterial agent yog ib hom tshuaj tua kab mob ntuj, uas feem ntau suav nrog cov roj tseem ceeb, tshuaj tua kab mob peptides, terpenes, polysaccharides, alkaloids, chitosan, amino acids, polypeptides, thiab qee cov microbial metabolites thiab endophytes. Cov tshuaj tua kab mob no tuaj yeem tiv thaiv cov protein, thaiv lub zog synthesis, cuam tshuam nrog cov metabolism hauv cell, thiab siv cov tshuaj tua kab mob.
Kev ntim tshuaj tua kab mob ntuj tau nyiam ntau thiab ntau dua vim nws txoj kev nyab xeeb, tsis muaj tshuaj lom, thiab muaj cov kab mob tua kab mob siab.
3. Daim ntawv thov kev ntim khoom thaiv
Barrier yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm kev ntim khoom noj, tshwj xeeb tshaj yog nyob rau hauv cov khoom noj khoom haus. Nws ua raws li cov txheej txheem tiv thaiv lossis qee yam kev thaiv. Nws tuaj yeem tiv thaiv cov khoom noj los ntawm kev lwj los ntawm kev thaiv cov kab mob sab nraud, gases, lub teeb thiab noo noo.
Hauv lub neej tiag tiag, cov ntaub ntawv ntim cov khoom siv dav siv hauv cov ntim khoom noj muaj xws li cov khoom siv oxygen barrier, cov khoom siv teeb pom kev zoo, cov ntaub ntawv pov thawj noo noo thiab cov ntaub ntawv antistatic. Txhawm rau muab kev ua si tag nrho rau qhov cuam tshuam zoo heev ntawm cov khoom ntim, ntau cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab tau siv rau hauv kev tsim cov khoom thaiv kev ntim khoom nyob rau xyoo tas los no, xws li ntxiv cov ntaub ntawv nano rau cov ntim khoom matrix thiab txau nano coatings ntawm lub ntim nto los txhim kho cov nyhuv barrier.
Nyob rau hauv cov txheej txheem ntim, cov khoom ntim ua ntej ntim cov noodles tshiab thiab ntub dej tuaj yeem raug thaiv, thiab cov yam ntxwv tshwj xeeb ntawm cov khoom siv tuaj yeem siv los tiv thaiv kev khiav tawm ntawm lub teeb thiab ntau cov dej sab nraud (sab hauv). Tib lub sijhawm, nws tuaj yeem tiv thaiv lub teeb ncaj qha (lossis ultraviolet lub teeb hauv lub teeb) los ntawm kev ua kom muaj qee yam enzymes hauv cov noodles tshiab thiab ntub dej, ua rau cov duab xim av; Tsis tas li ntawd, kev siv cov txheej txheem ntim khoom thaiv thaiv lub teeb tuaj yeem txo qhov degeneration ntawm qee cov chromophores hauv cov protein, txhawm rau muab qee yam kev txhawb nqa rau txuas lub txee lub neej ntawm cov noodles tshiab thiab ntub dej.
4. Daim ntawv thov kev hloov pauv huab cua ntim
Kev hloov pauv huab cua ntim feem ntau yog siv cov roj inert lossis lwm cov pa roj uas tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob kom txo tau cov ntsiab lus oxygen, yog li ncua lub txee lub neej. Hauv kev thov tiag tiag, N2, CO2 thiab O3 tau siv dav. Feem ntau, ob lossis peb ntawm peb cov roj no tau muab sib xyaw rau hauv pob hauv ib qho kev faib ua feem kom ua tiav cov nyhuv tiv thaiv corrosion.
Cov kws tshawb fawb hauv tsev thiab txawv teb chaws kuj tau ua tiav ntau qhov txiaj ntsig zoo hauv qhov no. Piv txwv li, cov kws tshawb fawb tau pom tias ntxiv cov pa roj carbon dioxide rau hauv ntim tuaj yeem cuam tshuam kev tsim cov kab mob. Qee cov kws tshawb fawb tau pom tias lub txee lub neej ntawm cov noodles tshiab thiab ntub dej tuaj yeem ncav cuag li ob lub hlis ntawm 4 o' moos. Thaum qhov sib xyaw ntawm O2 thiab CO2 yog 3: 7, qhov hloov pauv huab cua ntim yog sib xyaw nrog chitosan. Tsis tas li ntawd, lawv kuj pom tau hais tias kev siv cov pa roj carbon dioxide nyob rau hauv kev hloov pauv huab cua ntim tsis tau tsuas yog ua kom lub txee lub neej ntawm cov noodles tshiab thiab ntub dej, tab sis kuj tseem muaj txiaj ntsig zoo rau kev tiv thaiv cov xim ntawm cov noodles thiab tiv thaiv cov browning ntawm cov noodles. .
Guangzhou Biaoji tsom mus rau kev tshawb fawb thiab kev txhim kho cov khoom ntsuas ntim, thiab muab cov kev pabcuam thib peb hauv kev sim, muab cov neeg siv khoom ntim khoom, khoom noj, tshuaj thiab lwm yam lag luam nrog cov dej vapor kis tus nqi testers, roj kis tus nqi testers, thiab oxygen kis tus nqi testers , Mask Lim Detector thiab lwm yam khoom siv kuaj, Guangzhou Biaoji, koj ntseeg siab ntim khoom kuaj cov chaw tsim khoom.
