Qhov sib txawv tseem ceeb ntawm kev npau npau thiab pasteurization yog qhov npauj npaim tuaj yeem rhuav tshem tag nrho cov kab mob thiab deactivate enzymes hauv cov zaub mov ntawm qhov kub thiab txias, whereas pasteurization tuaj yeem rhuav tshem cov kab mob thiab deactivate enzymes hauv cov zaub mov ntawm qhov kub thiab txias.
Boiling yog txheej txheem kev lag luam uas siv qhov kub thiab txias los rhuav tshem tag nrho cov enzymes thiab yuav luag tag nrho cov kab mob hauv cov zaub mov. Pasteurization yog txheej txheem kev lag luam uas muaj txiaj ntsig zoo hauv kev khaws cov khoom ntim thiab tsis ntim khoom.
Boiling yog dab tsi?
Boiling yog txheej txheem kev lag luam uas siv qhov kub thiab txias los rhuav tshem tag nrho cov enzymes thiab yuav luag tag nrho cov kab mob hauv cov zaub mov. Yog li ntawd, nws yog ib txoj kev zoo heev ntawm kev khaws cov zaub mov. Peb tuaj yeem yooj yim rhuav tshem cov kab mob hauv cov zaub mov acidic, suav nrog txiv hmab txiv ntoo, siv cua sov. Tsis tas li ntawd, peb yuav tsum siv cov thawv ntim khoom ntim thiab airless rau boiled khaws cia kom ntev lub neej txee ntawm cov zaub mov.
Feem ntau, peb tuaj yeem siv txoj kev sib xyaw ua ke ntawm boiling thiab canning rau cov khoom noj xws li nqaij, ntses, syrup, dej qab zib, kua tshuaj, thiab lwm yam. Nyob rau hauv feem ntau industrial cov zaub mov preserving txoj kev, rhawv zeb ntawm cov zaub mov yog rhuab los ntawm kev ua. npog tag nrog dej npau.
YPasteurization yog dab tsi?
Pasteurization yog txheej txheem kev lag luam uas muaj txiaj ntsig zoo hauv kev khaws cov khoom ntim thiab tsis ntim khoom. Cov zaub mov no suav nrog mis nyuj thiab kua txiv hmab txiv ntoo. Hauv cov txheej txheem no, cov zaub mov raug kho nrog cov cua sov me me (feem ntau tsawg dua 100 degrees Celsius), uas yuav pab tau tshem tawm cov kab mob, yog li ncua lub txee lub neej ntawm cov zaub mov. Pasteurization tuaj yeem rhuav tshem lossis rhuav tshem cov kab mob (thiab qee zaum cov enzymes) uas yog lub luag haujlwm rau kev lwj ntawm cov zaub mov thiab tuaj yeem ua rau muaj kab mob thaum peb noj lawv. Txawm li cas los xij, cov txheej txheem no tsis tuaj yeem rhuav tshem cov kab mob spores.
Lub npe pasteurization los tom qab tus kws tshawb fawb Louis Pasteur. Nws yog ib tug Fabkis microbiologist uas qhia tau hais tias thermal ua ntawm cov zaub mov tuaj yeem deactivate cov kab mob uas tsis xav tau hauv cawv. Txawm li cas los xij, thaum qhov kev kho cua sov no, cov enzymes tsis xav tau kuj tau deactivated. Tam sim no, pasteurization yog pab tau tshwj xeeb hauv kev lag luam khoom noj siv mis thiab qee qhov kev lag luam khoom noj uas peb xav tau kev txuag zaub mov thiab kev nyab xeeb khoom noj.
Thaum lub sijhawm txheej txheem pasteurization, peb siv cov kev kho cua sov me me ntawm cov khoom noj ua kua. Qhov kub ntawm cov txheej txheem tseem nyob hauv qab 100 degrees Celsius txhawm rau tiv thaiv cov theem hloov ntawm cov kua hauv lub xeev ntawm cov zaub mov. Ntxiv mus, lub sij hawm thiab kub yuav tsum tau rau cov khoom noj yog nyob ntawm acidity ntawm cov zaub mov. Tsis tas li ntawd, peb yuav tsum xav txog cov khoom noj khoom haus thiab qhov zoo ntawm cov khoom noj thaum xaiv qhov kub thiab txias rau cov txheej txheem. Muaj ob txoj hauv kev loj ntawm pasteurizing zaub mov: ua ntej lossis tom qab ntim cov zaub mov rau hauv ntim.
Txawm hais tias pasteurization tsis tuaj yeem rhuav tshem cov kab mob spores, ob txoj kev pasteurization tuaj yeem rhuav tshem cov spores thiab. Nws suav nrog cov txheej txheem cua sov thib ob. Yog li ntawd, nws tuaj yeem txuas lub neej txee ntawm cov zaub mov.
Qhov txawv ntawm Boiling thiab Pasteurization yog dab tsi?
Boiling yog txheej txheem kev lag luam uas siv qhov kub thiab txias los rhuav tshem tag nrho cov enzyme kev ua haujlwm thiab yuav luag tag nrho cov kab mob hauv cov zaub mov. Pasteurization yog txheej txheem kev lag luam uas muaj txiaj ntsig zoo hauv kev khaws cov khoom ntim thiab tsis ntim khoom. Qhov sib txawv tseem ceeb ntawm kev ua kom sov thiab pasteurization yog tias boiling tuaj yeem rhuav tshem tag nrho cov kab mob thiab deactivate enzymes hauv cov zaub mov ntawm qhov kub thiab txias, thaum pasteurization tuaj yeem rhuav tshem cov kab mob thiab deactivate enzymes hauv cov zaub mov ntawm qhov kub thiab txias.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm kev npau taws thiab pasteurization rau ib sab ntawm kev sib piv.
Summary – Boiling vs Pasteurization
Boiling thiab pasteurization yog cov txheej txheem thermal tseem ceeb uas muaj txiaj ntsig zoo hauv kev lag luam khoom noj. Qhov sib txawv tseem ceeb ntawm kev npau npau thiab pasteurization yog tias kev npau taws tuaj yeem rhuav tshem tag nrho cov kab mob thiab deactivate enzymes hauv cov zaub mov ntawm qhov kub thiab txias, thaum pasteurization tuaj yeem rhuav tshem cov kab mob thiab deactivate enzymes hauv cov zaub mov ntawm qhov kub thiab txias.
