Cov hauv qab no yog hais txog lub hauv paus ntsiab lus ntawm kev khaws cia ntawm lub tshuab nqus tsev, txhawm rau nkag siab txog qhov teeb meem ntawm lub neej txee: lub tshuab nqus tsev siv cov pa oxygen yog cov haujlwm tseem ceeb ntawm lub tshuab nqus tsev ntim khoom, txhawm rau tiv thaiv cov khoom noj kom tsis txhob lwj, lub hauv paus ntsiab lus yog qhov yooj yim heev. Vim tias cov pwm zaub mov puas tsuaj feem ntau yog los ntawm kev ua haujlwm ntawm cov kab mob me me, thiab feem ntau cov kab mob me me (xws li pwm thiab poov xab) Cov kev xav tau kev ciaj sia ntawm cov pa oxygen, thiab lub tshuab nqus tsev ntim khoom yog siv lub hauv paus ntsiab lus no. Lub hnab zaub mov thiab cov pa oxygen hauv cov hlwb tau raug tshem tawm, cov kab mob me me poob nws & lwm yam Ib puag ncig & thoob plaws; 。 Cov txiaj ntsig qhia tau tias thaum cov pa oxygen concentration hauv lub hnab tsawg dua 1%, kev loj hlob ntawm cov kab mob me me rov tshwm sim poob qis, cov pa oxygen concentration & le; Txog xoom. 5%, feem ntau cov kab mob me me raug txwv, tsis txhob yug me nyuam. Nco ntsoov: lub tshuab nqus tsev ntim khoom tuaj yeem tiv thaiv cov kab mob anaerobic yug me nyuam thiab cov tshuaj tiv thaiv enzyme los ntawm kev puas tsuaj ntawm cov khoom noj, nrog rau kev khov, khov, qhuav, kub siab sterilization, irradiation sterilization, microwave sterilization, ntsev thiab lwm yam kev pab. Kev siv lub tshuab nqus tsev deaerating tsis yog tsuas yog tiv thaiv kev loj hlob ntawm cov kab mob me me xwb, tab sis lwm yam tseem ceeb yog tiv thaiv kev oxidation ntawm cov khoom noj, vim tias cov khoom noj uas muaj roj ntau ntau cov roj fatty acids uas tsis tau saturated, oxidation los ntawm oxygen ua rau cov khoom noj hloov pauv cov saj. Tsis tas li ntawd, oxidation kuj ua rau cov vitamin A thiab vitamin C poob, cov xim zaub mov tsis ruaj khov nyob rau hauv kev cuam tshuam ntawm oxygen, ua rau cov xim tsaus dua. Oxygen tuaj yeem tiv thaiv kev puas tsuaj ntawm cov khoom noj, yog li ntawd, nws khaws nws cov xim, aroma, saj thiab cov txiaj ntsig zoo. Tsuav nws tuaj yeem ncav cuag qee qib nqus tsev, cov nyhuv yog tib yam.

Kev tau txais tsis tas yuav kim, siv sijhawm ntau, lossis nyuaj. Txhua yam nws yog nyob ntawm txoj kev zoo thiab lub tshuab ntsuas qhov hnyav.

Txhua lub tswv yim mus sij hawm ntev thiab cov haujlwm luv luv ntawm Smart Weigh yuav raug tsim los ntawm cov qauv tseem ceeb uas txhua tus neeg koom tes sib koom.

Lub tshuab ntsuas qhov hnyav muag hauv kev ua lag luam saib xyuas thiab muaj lub koob npe nrov. Dhau li ntawm qhov ntawd, peb cov khoom muag nrog tus nqi tsim nyog.
