Raw Khoom Rau Cov Khob Khob Khob Khob

Cov khob ntawv tsis zoo siv cov polyethylene rov siv dua, uas yuav raug hloov pauv thaum rov ua dua, ua rau muaj ntau yam teeb meem, uas muaj feem ntau yuav tsiv mus rau dej thaum siv. Xibfwb Zhang Qinfa, tus kws tshaj lij ntawm cov khoom ntim khoom noj los ntawm Lub Tsev Kawm Ntawv ntawm Food Science ntawm South China Agricultural University, ib zaug tau taw qhia tias txhawm rau ua tiav cov dej thaiv dej hauv kev tsim cov khob ntawv, txheej txheej ntawm polyethylene dej barrier zaj duab xis yuav yog. coated rau ntawm phab ntsa sab hauv. Polyethylene yog cov tshuaj muaj kev nyab xeeb tshaj plaws hauv kev ua zaub mov. Txawm li cas los xij, yog tias cov khoom xaiv tsis zoo lossis cov txheej txheem kev ua haujlwm tsis zoo txaus, cov polyethylene yuav raug oxidized rau carbonyl compounds thaum lub sij hawm kub melting los yog siv rau cov khob ntawv. Carbonyl tebchaw tsis yooj yim volatile ntawm chav tsev kub, tab sis tej zaum yuav volatilize thaum cov dej kub yog nchuav rau hauv lub khob ntawv, yog li ntawd tib neeg yuav hnov qab txawv txawv. Los ntawm kev tsom xam dav dav, kev noj haus mus sij hawm ntev ntawm cov organic compound no yuav tsum muaj kev phom sij rau tib neeg lub cev.
