Qhov sib txawv tseem ceeb ntawm tyndallization thiab pasteurization yog tias tyndallization yog ib txoj kev ua kom tsis muaj menyuam uas muaj cua sov cov khoom ntawm 100 ° C rau 20 feeb ntawm 3 hnub sib law liag nrog incubation ntawm 37 ° C thaum pasteurization yog ib txoj hauv kev uas muaj feem xyuam nrog. cua sov ntawm cov mis nyuj kub ntawm 63 ° C rau 30 feeb los yog ntawm 72 ° C rau 15-20 vib nas this tom qab txias sai sai rau 13 ° C.
Kev ua kom tsis muaj menyuam yog kev puas tsuaj ntawm txhua hom kab mob microbial lub neej los ntawm cov ntaub ntawv thiab thaj chaw. Lub hom phiaj ntawm kev ua qhov no yog txhawm rau tiv thaiv kev sib kis ntawm qee yam kab mob nrog cov khoom, tes lossis tawv nqaij thiab tiv thaiv kev kis kab mob. Muaj cov txheej txheem ntawm lub cev thiab tshuaj sterilization. Kev siv cov cua sov yog qhov tseem ceeb hauv ntau txoj kev ua kom tsis muaj menyuam hauv lub cev xws li incineration, tyndallization, autoclaving, cua kub qhov cub, pasteurization, direct flaming, thiab lwm yam. Kab lus no qhia txog qhov txawv ntawm tyndallization thiab pasteurization.
Tyndallization yog dab tsi?
Tyndallization lossis fractional sterilization yog ib txoj kev ua kom tsis muaj menyuam. Qhov no suav nrog cua sov cov khoom ntawm 100 ° C rau 20 feeb ntawm peb hnub sib law liag, cuam tshuam nrog incubation ntawm 37 ° C. Tom qab raug tshav kub, cov noob qoob loo yuav raug rhuav tshem, thiab cov spores uas nyob twj ywm tsis muaj kev puas tsuaj yuav germinate thaum lub sij hawm incubation. Tom qab ntawd, thaum lub sij hawm thib ob cua sov, cov germinated spores yuav raug puas tsuaj dua. Rov ua cov txheej txheem rau peb hnub kom paub meej txog kev loj hlob ntawm tag nrho cov spores thiab kev puas tsuaj ntawm tag nrho cov vegetative cells.
Daim duab 01: Tyndallization
Tyndallization feem ntau yog siv los ua kom tsis muaj kab mob kab lis kev cai thiab cov tshuaj daws teeb meem uas tsis tuaj yeem ua kom sov siab tshaj 100 ° C. Txawm li cas los xij, tyndallization tsis yog ib txoj hauv kev tsim nyog los tua anaerobic spores thiab thermophiles.
YPasteurization yog dab tsi?
Y Pasteurization yog ib txoj kev ntawm cov cua sov uas tshem tawm cov kab mob kab mob hauv cov mis nyuj thiab dej haus. Fabkis tus kws tshawb fawb Louis Pasteur tau tsim cov qauv no. Cov dej haus tshiab xws li mis nyuj, kua txiv hmab txiv ntoo, npias vine yog cov kab mob yooj yim thaum sau thiab ua. Rau pasteurization ntawm mis nyuj, qhov kub thiab txias siv yog 63 ° C rau 30 feeb lossis 72 ° C rau 15-20 vib nas this, tom qab ntawd txias sai sai rau 13 ° C.
Daim duab 02: Pasteurization
Lub hom phiaj tseem ceeb ntawm pasteurization yog los tiv thaiv kev kis tus kab mob los ntawm mis nyuj. Pasteurization kuj muaj qhov zoo ntawm kev ncua sij hawm cia mis nyuj. Txawm li cas los xij, txij li pasteurization tsis tuaj yeem tua tag nrho cov spores, nws tsis yog txoj kev ua kom tsis muaj zog.
Dab tsi yog qhov zoo sib xws ntawm Tyndallization thiab Pasteurization?
- Tyndallization thiab pasteurization yog ob txoj hauv kev hauv lub cev uas cuam tshuam nrog kev tshem tawm cov ntaub ntawv microbial los ntawm tej yam.
- Ob leeg siv cua sov kom tshem tawm cov kab mob.
Qhov txawv ntawm Tyndallization thiab Pasteurization yog dab tsi?
Tyndallization yog cua sov ntawm cov khoom ntawm 100 0C rau peb hnub sib law liag nrog lub sij hawm incubation nyob nruab nrab ntawm thaum pasteurization yog cua sov ntawm cov mis nyuj tshwj xeeb tshaj yog nyob rau ntawm 63 oC rau 30 feeb los yog 72 oC rau 15-20 vib nas this tom qab txias sai sai thiab sealing.. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm tyndallization thiab pasteurization. Qhov tseem ceeb tshaj plaws, tyndallization destructs tag nrho cov spores thiab vegetative hlwb, thaum pasteurization tsis tua spores thiab tag nrho cov vegetative hlwb. Nws tsuas tua cov kab mob pathogenic microorganisms. Yog li ntawd, qhov no kuj yog qhov sib txawv ntawm tyndallization thiab pasteurization.
Cov hauv qab no qhia txog qhov sib txawv ntawm tyndallization thiab pasteurization.
Summary – Tyndallization vs Pasteurization
Tyndallization yog ib txoj kev ua kom tsis muaj menyuam uas tua txhua hom kab mob hauv lub neej, suav nrog cov spores. Ntawm qhov tod tes, pasteurization yog ib txoj hauv kev tshem tawm cov kab mob pathogenic feem ntau los ntawm cov mis nyuj thiab lwm yam dej haus. Tab sis, pasteurization tsis tua spores. Yog li ntawd, nws tsis yog ib txoj kev sterilization. Tyndallization, ntawm qhov tod tes, muaj cua sov cov khoom ntawm 100 ° C rau 20 feeb ntawm peb hnub sib law liag nrog incubation ntawm 37 ° C. Ntawm qhov tod tes, pasteurization muaj cua sov ntawm cov mis nyuj kub ntawm 63 ° C rau 30 feeb lossis ntawm 72 ° C rau 15-20 vib nas this, tom qab ntawd txias sai sai rau 13 ° C. Yog li, qhov no qhia txog qhov sib txawv ntawm tyndallization thiab pasteurization.
