Lub tshuab ua kua mis yog lub hauv paus ntawm cov mis nyuj, thiab kev nyab xeeb thiab kev huv yog qhov tseem ceeb ntawm cov khoom noj. Cov khoom noj khoom haus siab ntawm cov mis nyuj kuj yog lub vaj kaj siab rau kev ua haujlwm microbial, thiab kev ua kom tsis muaj menyuam ntawm cov khoom siv mis nyuj yog qhov txuas tseem ceeb heev. Cov txheej txheem ntawm cov khoom noj siv mis muaj xws li: kev tshuaj xyuas cov mis nyuj nyoos, cov mis nyuj huv, tub yees, preheating, homogeneous sterilization (los yog sterilization), txias, aseptic filling (los yog sterilization), fermentation, tiav cov khoom cia, thiab lwm yam, ntawm cov txheej txheem fermentation xws li Raws li tshuaj tua kab mob thiab ziab kom qhuav yuav tsum muaj chav, ntawm cov fermentation, tshuaj tua kab mob thiab ua kom tsis muaj menyuam hauv cov khoom siv mis nyuj yuav tsum muaj ntau tshaj plaws. high-temperature chav, thiab huv si thiab huv si khoom noj khoom haus-qib ntshiab chav tsev yog ib yam khoom tseem ceeb rau cov khoom siv mis nyuj.
Cov khoom noj mis fermentation yog hais txog kev fermentation ntawm cov mis nyuj nyoos los ntawm cov kab mob lactic acid los yog co-fermentation ntawm cov kab mob lactic acid thiab cov poov xab nyob rau hauv qhov kub thiab txias ib puag ncig nyob rau hauv qhov kev txiav txim ntawm cov kab mob tshwj xeeb los ua cov khoom noj mis acidic.
Cov khoom siv mis kom tsis muaj menyuam: pasteurize ntawm qhov kub tsis tshua muaj sijhawm ntev, khaws cov mis nyuj ntawm li 60 ° C rau 30 feeb; pasteurize ntawm qhov kub thiab txias thiab lub sij hawm luv luv, khaws cov mis nyuj ntawm 72 ~ 75 ° C rau 15 ~ 20S; Ultra-siab kub sterilization (UHT), khaws cov mis nyuj ntawm 135-140 ° C rau 3-6S; tom qab lub pob kom tsis muaj menyuam, khaws cov mis nyuj ntim ntawm 115-120 ° C rau 20-30 feeb.
Kev ua haujlwm tshwj xeeb ntawm cov pa ntshiab hauv kev ua kom tsis muaj menyuam hauv cov khoom noj siv mis, xws li ultra-high temperature sterilization (UHT), sib tov cov mis preheated nrog chav, ua kom sov rau 135 ° C tam sim, ua kom sov li ob peb feeb, thiab tom qab ntawd flashes rau txias sai sai thiab tshem tawm cov kua mis. Combined steam condenses dej. Nyob rau hauv txoj kev no, cov khoom siv mis nyuj tuaj yeem ua kom tsis muaj menyuam nyob rau hauv chav tsev kub thiab khaws cia rau lub sijhawm ntev, thaum tsis txhob cuam tshuam rau cov kua mis saj, thiab xyuas kom meej tias cov mis nyuj tsis cuam tshuam los ntawm cov khoom xws li dej rauv, hlau slag, tshuaj kho dej. , thiab tsw. Nqa los ntawm kev lag luam chav. Kev npam. Nobles chav generators ua raws li FDA thiab EN285 cov cai rau chav dej ntshiab. Nyob rau tib lub sijhawm, kev txawj ntse hloov pauv hloov tswj tau tuaj yeem paub txog cov khoom siv hluav taws xob tam sim thiab qhov xav tau ntawm cov khoom siv hluav taws xob, tsis txhob nkim lub zog ntawm cov chaw lag luam.
Nyob rau tib lub sijhawm, cov kab ntau lawm tsis siv neeg thiab ntse saib xyuas lub tshuab hluav taws xob hauv qhov chaw ua haujlwm ntawm cov khoom noj siv mis kom ntseeg tau tias lub zog siab nyob twj ywm tsis tu ncua thiab cov txheej txheem siab raug tshem tawm, kev tswj xyuas phau ntawv raug tshem tawm, thiab lub peev xwm ntawm kev tsim khoom. kab yog txhim kho.
