Pasteurization yog txheej txheem uas cov khoom lag luam tau rhaub rau lub sijhawm luv luv mus rau qhov kub thiab txias, yog li cov kab mob me me thiab lawv cov khoom noj tsis raug puas tsuaj tag nrho, tab sis tsuas yog nres lawv txoj kev txhim kho, cia cov khoom lag luam khaws cia ntev.

Cov kws tshaj lij feem ntau siv cov txheej txheem pasteurization nyob rau hauv qhov cua sov dhau 1 feeb ntawm qhov kub ntawm 60-80 degrees Celsius.

Piv txwv li, cov mis tshiab zoo uas tau muab tso ua ke yuav tsum muab rhaub kom ntev li 1 feeb ntawm qhov kub txog 95 degrees Celsius. Yog li, nrov UHT pasteurization tshuab tsis kam los ntawm ntau.

Hauv nws, cov tshuaj pasteurization ntawm cov mis tshiab yog nqa tawm ntev li 2 feeb ntawm qhov kub ntawm 140 degrees Celsius. Qhov no yeej ua rau txhua yam muaj sia, tab sis kuj muaj txiaj ntsig.

Cov mis uas npaj rau hauv txoj hauv kev no tuav nws qab qab thiab tuaj yeem khaws cia tsis qhib rau lub xyoo, tab sis ntau ntawm nws cov khoom xyaw tseem ceeb kuj ploj.

Feem ntau cov khoom yog pasteurized ua ntej lub rhaub taw siab dhau thiab txias dua tam sim ntawd. Nov yog qhov cov mis tshiab peb tau npaj.

Nws yog ib qho tseem ceeb uas yuav tsum hais tias cov casein muaj txiaj ntsig, uas yog cov mis muaj protein, ploj lawm txawm muaj kev kho cua sov tshaj 50 degrees Celsius.

Ntawm qhov tod tes, cov kua mis peb haus tsis tuaj yeem ua kom tshiab thiab nplua nuj nyob hauv casein, vim tias nws tuaj yeem muaj ntau cov kab mob phem nyob rau tib lub sijhawm.
