Feem ntau siv cov deoxidizers siv cov qauv tshuaj tiv thaiv xws li hlau hmoov oxidation (hlau-raws li), enzyme oxidation (enzyme-raws li), ascorbic acid oxidation, thiab photosensitive dye oxidation. Feem ntau deoxidizers siv yog raws li hlau hmoov oxidation. Cov hlau no-raws li deoxidizers tuaj yeem ntim rau hauv hnab kom txo cov pa oxygen mus rau 0.01%. Feem ntau, 1g ntawm cov hmoov hlau yuav tsum hnov mob nrog 300mL ntawm oxygen. Cov koob tshuaj uas tsim nyog yuav tsum raug xaiv raws li tus nqi ntawm cov pa seem tom qab ntim thiab cov pa permeability ntawm lub ntim zaj duab xis. Cov ntawv thov suav nrog cov khoom qab zib, cov khoom noj txom ncauj qhuav, cov khoom noj nqaij, cov ncuav mov, pasta, cheese, thiab zaub qhuav. Ntxiv rau cov hnab ntim deoxidizers, cov ntawv yas lossis ntau daim npav uas muaj cov hmoov hlau ua haujlwm kuj tau muab tso rau hauv lub ntim.
Dhau li hlau-raws li deoxidizers, enzyme-raws li deoxidizers kuj tau siv dav. Enzyme-raws li deoxidizers rhiab heev rau kev hloov pauv hauv pH, Aw, ntsev cov ntsiab lus, kub, thiab lwm yam, thiab xav tau dej thaum lub sij hawm cov tshuaj tiv thaiv. Yog li ntawd, lawv tsis muaj txiaj ntsig zoo hauv cov khoom noj uas muaj cov dej noo tsawg. Txawm li cas los xij, hauv lub raj mis npias lossis dab, qhov deoxidizer no tuaj yeem ua ncaj qha rau hauv pob ntawv me me thiab muab tso rau hauv lub raj mis. Xwb, cov tshuab enzyme tuaj yeem raug immobilized ntawm polypropylene lossis polyethylene films. Lwm hom deoxidizer yog photosensitive dye deoxidizer. Lub tshuab deoxidation no suav nrog kev sib khi ib daim ntawv me me ntawm ethyl cellulose zaj duab xis (muaj cov xim zoo nkauj thiab cov pa oxygen txais ib leeg nyob hauv) nyob rau sab saum toj hauv lub hnab ntim pob tshab. Thaum cov zaj duab xis ntim tau raug rau lub teeb ntawm lub teeb uas tsim nyog, cov xim zoo nkauj molecules sensitize oxygen molecules uas tau permeated rau hauv lub ntim zaj duab xis rau hauv singlet oxygen. Cov singlet oxygen molecules tom qab ntawd hnov mob nrog cov neeg txais khoom molecules thiab tau noj. O2TM los ntawm Australia yog tsim los rau ntau yam khoom ntim yas. Cov reactive Cheebtsam nyob rau hauv cov ntaub ntawv no tsuas yog ua kom nquag plias tom qab ua kom lub teeb ultraviolet los yog lub zog siab, ua rau nws tsim nyog rau kev ua films, nplooj ntawv, thiab coatings. Kev ntsuam xyuas ntawm O2TM muaj nyob rau hauv cov khaubncaws sab nraud povtseg tau pom tias pwm tuaj yeem cuam tshuam thaum tsis muaj cov pa roj carbon dioxide, thiab nws tuaj yeem tiv thaiv cov nqaij npua los ntawm fading nyob rau hauv lub teeb pom kev.
