High-temperature sterilization tso cai rau cov zaub mov khaws cia nyob rau hauv chav tsev kub rau lub hlis los yog txawm xyoo tsis siv tshuaj preservatives. Txawm li cas los xij, yog tias kev ua kom tsis muaj menyuam tsis ua raws li cov txheej txheem kev tu cev thiab raws li kev ua kom tsis muaj menyuam, nws yuav ua rau muaj teeb meem kev nyab xeeb ntawm zaub mov.
Qee cov kab mob microbial tuaj yeem tiv taus qhov kub thiab txias thiab tsim cov co toxins uas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv. Qhov no yog cov kab mob botulism, ib qho mob hnyav tshwm sim los ntawm botulinum toxin tsim los ntawm cov kab mob Clostridium botulinum.
Kev lom botulism feem ntau muaj qhov tshwm sim loj heev.2021 Ib tsev neeg tau yuav lub tshuab nqus tsev ham sausage, nqaij qaib taw, ntses me me, thiab lwm yam khoom noj txom ncauj ntawm lub khw me thiab noj rau noj hmo, thiab hnub tom qab ib tsev neeg ntawm plaub tus neeg mob ntuav, raws plab, thiab tsis muaj zog ntawm cov ceg tawv, ua rau muaj qhov tshwm sim loj ntawm ib tus neeg tuag thiab peb tus neeg nyob hauv kev soj ntsuam hauv chav saib xyuas mob hnyav. Yog li vim li cas thiaj tseem muaj cov khoom noj muaj botulinum toxin lom hauv cov khoom noj uas nqus tau?
Clostridium botulinum yog cov kab mob anaerobic, uas feem ntau tshwm sim hauv cov khoom noj nqaij, cov khoom noj kaus poom thiab cov khoom noj uas nqus tau. Feem ntau cov neeg yuav siv cov txheej txheem kub kom tsis muaj menyuam kom tsis muaj menyuam cov khoom noj, cov khoom lag luam hauv kev ua kom tsis muaj menyuam, txhawm rau ua kom tsis muaj menyuam yuav tsum tau ua kom tsis muaj menyuam hauv lub retort rau lub sijhawm ntev txaus los tua cov kab mob phem thiab lawv cov spores hauv cov zaub mov. .
Txhawm rau zam botulism, muaj ob peb yam uas yuav tsum tau saib xyuas ntxiv:
1.Siv cov ntaub ntawv tshiab uas ua tau raws li cov qauv kev huv rau kev npaj.
2. Ua tib zoo ntxuav tag nrho cov tais diav thiab ntim khoom siv.
3. Xyuas kom meej tias cov khoom ntim tau kaw nruj nreem.
4.Ua raws li qhov tsim nyog kom tsis muaj menyuam kub thiab lub sijhawm ntev.
5.Sterilization kev kho tsis yog nyob ntawm seb hom zaub mov yuav khaws cia.
Rau cov khoom noj uas muaj kua qaub (pH tsawg dua 4.5), xws li txiv hmab txiv ntoo, lawv muaj peev xwm tiv taus botulism ntau dua. Sterilization los ntawm boiling dej (100 ° C) rau ib lub sij hawm yoog mus rau lub ntim hom thiab cov khoom muaj kev txhawj xeeb yog txaus.
Rau cov khoom noj uas tsis muaj kua qaub (pH ntau dua 4.5), xws li nqaij, ntses, thiab zaub siav, nws yuav tsum tau ua kom tsis muaj qhov kub thiab txias kom tua Clostridium botulinum spores. Sterilization nyob rau hauv siab nrog kub siab tshaj 100 ° C yog pom zoo. Cov txheej txheem yuav tsum tau nyob ntawm cov khoom thiab nws cov hom, nrog rau qhov nruab nrab kub nyob ib ncig ntawm 120 ° C.
Clostridium botulinum: sterilization los ntawm industrial autoclave
Industrial autoclave sterilization yog txoj kev ua kom tsis muaj menyuam zoo tshaj plaws rau kev tua Clostridium botulinum, cov kab mob uas ua rau botulism. Kev lag luam autoclaves tuaj yeem ncav cuag qhov kub ntau dua li cov autoclaves hauv tsev, ua kom muaj kev puas tsuaj ntawm cov kab mob.
DTS autoclave retort ua kom muaj qhov kub thiab txias thiab rov ua dua tshiab hauv lub nkoj, uas yog kev ruaj ntseg lav rau kev ua kom tsis muaj menyuam.
DTS retort: Sterilization nrog kev ntseeg siab
DTS muaj ntau hom autoclaves rau kev lag luam zaub mov. Tus qauv tsim ntawm cov retorts no ua kom zoo zoo sib xws ntawm cov khoom siv hluav taws xob thaum lub sij hawm ua zaub mov kom tsis muaj menyuam, lav kom muaj homogeneous sterilizing nyhuv rau tag nrho cov khoom thauj khoom. Cov txheej txheem tswj ntawm lub autoclave ua kom muaj kev nyab xeeb ntawm cov txheej txheem zaub mov thiab lav zoo meej lub voj voog rov ua dua.
Tsis tas li ntawd, peb pab pawg kws tshaj lij yuav muab kev txhawb nqa rau koj ntawm kev siv autoclaves kom muaj kev nyab xeeb thiab txhim khu kev qha khoom kom tsis muaj menyuam.
