Raws li txoj kev tshawb fawb, muaj ntau yam uas cuam tshuam rau cov txiaj ntsig kom tsis muaj menyuam, xws li cov khoom noj ua ntej, cov khoom xyaw, thiab thaum pib kub ntawm cov kaus poom.
1. Cov qib ntawm cov khoom noj ua ntej ua ntej tsis muaj menyuam
Los ntawm cov khoom siv raw ua rau muaj peev xwm ua tau kom tsis muaj menyuam, yuav raug cov zaub mov sib txawv ntawm kev sib kis microbial. Qhov ntau dua cov nqi tsis huv, thiab lub sijhawm ntev dua yuav tsum muaj rau kom tsis muaj menyuam ntawm qhov kub tib yam.
2. Khoom noj khoom haus khoom noj
(1) Cov zaub mov kaus poom muaj qab zib, ntsev, protein, rog thiab lwm yam zaub mov uas tuaj yeem cuam tshuam cov microrganism tsis kam ntawm cov microrganism.
(2) Cov khoom noj uas muaj cov ntsiab lus siab acidity feem ntau yog sterilized ntawm qis dua kub thiab rau lub sijhawm luv luv.
3. Thaum Tshav Kub Hloov
Thaum cua sov kom tsis muaj menyuam hauv cov kaus poom khoom, lub ntsiab hom ntawm cov cua sov hloov yog conduction thiab convection.
(1) Hom thiab cov duab ntawm Canning ntim
Tinned nyias hlau hlau hloov chaw sov dua li cov iav iav nrawm dua cov kaus poom iav, thiab cov kaus poom me me hloov thaum nrawm dua cov kaus poom loj dua. Tib lub ntim ntawm cov kaus poom, cov kaus poom ntau dua li luv tau cov tuaj yeem hloov pauv kub sai dua
(2) hom khoom noj
Hloov cov dej ua kua dej nrawm dua, kua qab zib, cov dej qab zib kua kub hloov nrog nws cov kev xav nce thiab txo qis. Cov khoom noj khoom haus cua kub hloov tau qeeb. Thaum tshav kub hloov ntawm thaiv cov poom loj thiab kaus poom nruj qeeb qeeb.
(3) Kev ua kua mis kom tsis muaj menyuam thiab cov kaus poom hauv cov lauj kaub kom tsis muaj menyuam
Teb kom tsis muaj menyuam tsis muaj txiaj ntsig zoo dua li qub ua kom tsis muaj menyuam, thiab lub sijhawm luv luv. Cov kub hloov yog qeeb vim tias cov kaus poom hauv lub lauj kaub kom tsis muaj menyuam thaum ntsuas kub hauv lub lauj kaub tsis tau mus txog.
(4) Thaum pib kub ntawm lub tau
Ua ntej kom tsis muaj menyuam, qhov pib kub ntawm cov zaub mov hauv lub tuaj yeem nce, uas yog qhov tseem ceeb rau cov consts yooj yim thiab kev hloov pauv qeeb.
