Raws li kev tshawb fawb, muaj ntau yam uas cuam tshuam rau kev ua kom tsis muaj menyuam ntawm cov kaus poom, xws li qib ntawm cov khoom noj kom tsis muaj menyuam ua ntej kom tsis muaj menyuam, cov khoom xyaw zaub mov, kev hloov hluav taws xob, thiab qhov pib kub ntawm cov kaus poom.
1. Qib ntawm kev kis kab mob ntawm cov zaub mov ua ntej kom tsis muaj menyuam
Los ntawm kev ua cov khoom siv raw mus rau cov kaus poom kom tsis muaj menyuam, cov zaub mov yuav raug sib txawv ntawm cov kab mob microbial. Qhov kev sib kis ntau dua, thiab lub sijhawm ntev dua rau kev ua kom tsis muaj menyuam nyob rau tib qhov kub thiab txias.
2. Cov khoom xyaw zaub mov
(1) Cov khoom noj hauv kaus poom muaj cov suab thaj, ntsev, cov protein, rog thiab lwm yam khoom noj uas tuaj yeem cuam tshuam cov cua sov ntawm cov kab mob.
(2) Cov khoom noj uas muaj acidity siab feem ntau yog sterilized ntawm qhov kub thiab txias thiab lub sij hawm luv.
3. Thaum tshav kub kub hloov
Thaum cua sov kom tsis muaj menyuam ntawm cov khoom hauv kaus poom, lub ntsiab ntawm kev hloov cov cua sov yog conduction thiab convection.
(1) Hom thiab cov duab ntawm cov thawv ntim khoom
Tinned nyias hlau cov kaus poom hloov kub sai dua cov kaus poom iav, thiab cov kaus poom me me hloov cov cua sov sai dua cov kaus poom loj. Tib lub ntim ntawm cov kaus poom, cov kaus poom tiaj tus dua li cov kaus poom luv luv kom sov sai dua
(2) Hom khoom noj
Cov kua zaub mov hloov pauv sai dua, tab sis cov kua qab zib, brine lossis flavoring kua kub hloov pauv nrog nws cov concentration nce thiab txo qis. Khoom noj khoom haus kub hloov pauv qeeb. Thaum tshav kub kub hloov ntawm qhov thaiv cov kaus poom loj thiab cov kaus poom nruj yog qeeb.
(3) Sterilization lauj kaub daim ntawv thiab cov kaus poom hauv lub lauj kaub kom tsis muaj menyuam
Rotary sterilization muaj txiaj ntsig zoo dua li kev ua kom tsis muaj menyuam, thiab lub sijhawm luv dua. Lub tshav kub hloov mus kuj qeeb vim tias cov kaus poom hauv lub lauj kaub kom tsis muaj menyuam kom deb ntawm lub raj xa dej thaum qhov kub hauv lub lauj kaub tsis ncav cuag qhov sib npaug.
(4) Thawj qhov kub ntawm lub kaus poom
Ua ntej kom tsis muaj menyuam, qhov pib kub ntawm cov zaub mov hauv lub kaus poom yuav tsum tau nce ntxiv, uas yog qhov tseem ceeb rau cov kaus poom uas tsis yooj yim rau convection thiab qeeb cua sov.
