Koj tus dev noj tus cwj pwm yuav ua rau koj ntseeg tias lawv muaj plab hlau. Nruab nrab ntawm kev khawb hauv lub thoob khib nyiab, noj lwm tus dev cov quav, thiab hnia cov tsiaj tuag, dev ua rau peb xav tias lawv tuaj yeem noj dab tsi. Tab sis dev tuaj yeem tau txais zaub mov lom los ntawm kev noj cov khoom uas muaj cov kab mob phem, suav nrog cov nqaij nyoos.
High-pressure processing (HPP) is a non-thermal method that reduces bacteria in food. Nws tau siv ntau xyoo rau tib neeg cov zaub mov uas tsis tuaj yeem ua noj. Qee qhov ua ntej ua guacamole thiab kua txiv hmab txiv ntoo siv HPP los tua cov kab mob, salmonella, thiab E. coli.
Kev siv HPP hauv cov khoom noj dev ua lag luam yog qhov tshiab thiab khi rau qhov kev thov loj hlob rau cov khoom noj nyoos thiab khoom noj. Nyeem ntxiv txog yuav ua li cas kev ua haujlwm siab rau cov khoom noj dev ua haujlwm, suav nrog nws qhov zoo thiab qhov tsis zoo.
Nws Ua Haujlwm Li Cas?
Cov kab mob phem uas muaj nyob hauv qee cov zaub mov nyoos tuaj yeem ua rau peb cov tsiaj muaj mob. Listeria, salmonella, thiab E. coli tsis tuaj yeem nyob hauv qhov chaw kub lossis kub siab. Cov tuam txhab lag luam dev tuaj yeem siv cov txheej txheem thermal (piv txwv li, ua noj) lossis kev ua haujlwm siab kom tshem tawm cov kab mob no.
Raws li nws lub npe qhia, HPP siv qhov chaw muaj kev kub ntxhov los tua cov kab mob. Cov kauj ruam dav dav ntawm HPP tau teev tseg hauv qab no.
- Cov zaub mov dev muab tso rau hauv lub thawv hloov tau yooj yim uas tuaj yeem nthuav dav, xws li yas. Cov iav thiab hlau tsis haum rau kev ua haujlwm siab.
- Cov khoom noj dev uas ntim tau muab tso rau hauv ib lub chamber uas muaj dej txias, uas siv txog li 87,000 phaus ntawm hydraulic siab ib square inch. Lub siab no tuav tau ob peb feeb. Rau ib lub ntsiab lus ntawm kev siv, lub siab pom nyob hauv qab dej hiav txwv yog li ntawm 3,000 txog 9,000 phaus ib square inch. Yog tias koj xav paub tias yog vim li cas HPP tsis tsim kom muaj kev ntxhov siab loj, nws yog vim tias tsis sib xws yog siv rau txhua sab ntawm lub ntim. Cov khoom noj dev khaws nws cov duab thiab zoo li thaum cov kab mob tuag.
- Raws li feem ntau cov zaub mov dev tau txais HPP hauv nws cov khw muag khoom ntim, nws yog ib qho ntawm cov kauj ruam kawg hauv kev tsim khoom. Tom qab HPP ua tiav, cov pob khoom raug tshuaj xyuas thiab xa mus rau cov muag khoom thiab cov khw muag khoom. Qee cov khoom xyaw dev noj cov khoom siv ua haujlwm siab ua ntej muab tso rau hauv cov khoom tiav.
Dab tsi yog qhov txawv ntawm kev ua haujlwm siab rau cov khoom noj dev?
Cov kauj ruam uas siv thaum lub sij hawm ua haujlwm siab yog tib yam rau txhua yam khoom noj, txawm tias nws yog koj tus tsiaj cov khoom noj lossis cov kua txiv hmab txiv ntoo uas koj haus thaum noj tshais. Raws li rau lub khw muag khoom noj dev, nqaij nyoos, "mos siav," thiab cov khoom siv khov khov qhuav qhuav siv cov txheej txheem siab tsis siv cua sov los tua cov kab mob phem.
High-pressure processing kuj hu ua Pascalization (tom qab tus tsim ntawm txoj kev), txias pasteurization, thiab ultra-high-pressure processing (UHP). Thaum lub npe txawv, txheej txheem yog lub npe.
Nws siv qhov twg?
Cov tuam txhab lag luam khoom noj dev siv HPP los tsim cov khoom muaj kev nyab xeeb yam tsis muaj zaub mov kom kub. Raws li kev ua haujlwm siab tsis siv cua sov, cov tuam txhab tuaj yeem muag cov khoom noj "raws" thiab "mos siav" thaum ntsib cov lus qhia kev nyab xeeb.
Cov neeg siv khoom txaus siab rau cov khoom noj dev nyoos thiab tsis ua haujlwm tsawg zuj zus ntxiv, tab sis ntau tus neeg tsis xav ua zaub mov hauv tsev. Kev xav ntawm kev tuav cov nqaij nyoos los yog tsim ib daim ntawv qhia zaub mov hauv tsev yog daunting. Npaj-rau-paub cov zaub mov nyoos uas tau ua tiav HPP raws li cov neeg siv khoom xav tau.
Koj tus dev yuav txaus siab rau cov khoom nyoos ua ib feem ntawm nws cov calorie ntau ntau txhua hnub. Tab sis hloov mus rau kev noj zaub mov tsis zoo yuav tsis yog qhov kev xaiv zoo rau txhua tus dev. Koj yuav tsum tham nrog koj tus kws kho tsiaj ua ntej koj hloov mus rau cov zaub mov nyoos, vim qee cov zaub mov nyoos yuav tsis muaj tag nrho cov as-ham uas koj tus dev xav tau kom noj qab haus huv.
Ntawm no yog qee lub tuam txhab khoom noj dev thiab lawv cov khoom lag luam hauv Asmeskas uas muag cov khoom lag luam siab:
- Stella and Chewy's Super Beef Pluas Noj Mixers Freeze-Dried Raw Dog Food Topper
- Merrick Backcountry Freeze-Dried Raw Grain-Free Chicken-Free Great Plains Red Recipe Big Game Recipe with Beef, Lamb & Luav
- Instinct Frozen Raw Bites Grain-Free Cage-Free Chicken Recipe.
Qhov zoo ntawm kev ua haujlwm siab rau cov khoom noj dev
Qhov zoo tshaj plaws ntawm kev ua haujlwm siab rau cov zaub mov dev yog tias nws txo qis cov kab mob phem yam tsis muaj cua sov lossis ua noj rau dev. Cov neeg txhawb nqa ntawm cov zaub mov nyoos ntseeg tias dev tau txais txiaj ntsig los ntawm kev noj zaub mov zoo ib yam li lawv cov poj koob yawm txwv noj, nqaij nyoos. HPP ua rau cov zaub mov no ua tau thaum tseem ua raws li kev coj noj coj ua niaj hnub no.
Muaj cov txiaj ntsig thib ob ntawm kev ua haujlwm siab thiab. HPP ncua lub txee lub neej ntawm cov zaub mov dev ntau npaum li 10x nrog tsawg dua los yog tsis muaj cov tshuaj tua kab mob. Qhov ntawd tsim cov khoom noj tsawg tsawg raws li cov khoom lag luam tag nrho lub neej. Cov neeg tsim khoom txo cov khoom pov tseg, cov khw muag khoom tuaj yeem khaws cov khoom noj ntawm lub txee ntev dua, thiab koj muaj sijhawm ntau los ua zaub mov rau koj tus dev.
Dog tsis yog tib qho uas tau txais txiaj ntsig los ntawm HPP. Tib neeg uas tuav cov nqaij nyoos tuaj yeem mob heev los ntawm cov kab mob phem uas HPP txo qis, suav nrog Listeria, salmonella, thiab E. coli. Kev ua haujlwm siab tiv thaiv tsiaj thiab lawv cov tswv kom tsis txhob muaj mob.
Disadvantages of High-Pressure Processing for Dog Food
Kev ua haujlwm siab yog "zoo, tab sis nws tsis zoo tag nrho," raws li cov kws tshaj lij ntawm PetMD. Cov kab mob botulism tuaj yeem tiv taus siab.
Raw cov neeg nyiam noj zaub mov nco ntsoov tias HPP tsis yog ua rau cov kab mob phem xwb, tab sis kuj txo lossis tshem tawm cov kab mob uas muaj txiaj ntsig thiab cov enzymes, thiab. Txawm hais tias qhov kev xav tsis zoo no, kev pub mis rau koj tus dev ib qho khoom noj dev ua lag luam uas tau ua tiav HPP muaj kev nyab xeeb dua li sim tsim koj tus kheej cov khoom noj nyoos siv cov nqaij nyoos.
Cov lus nug nquag nug (FAQs)
HPP puas zoo ib yam li Pasteurized?
Thaum nws tuaj yeem tsim kev tsis meej pem, qee qhov chaw xa mus rau HPP li "txias pasteurization." Tab sis tsis zoo li kev ua haujlwm siab, pasteurization siv cua sov los tua cov kab mob phem hauv cov zaub mov thiab dej haus. Piv txwv li, cov mis nyuj pasteurized muag hauv Teb Chaws Asmeskas yog rhuab mus rau 145 degrees Fahrenheit thiab tuav ntawm qhov kub li 30 feeb.
Leejtwg Invented High-Pressure Processing?
High-pressure processing muaj keeb kwm ntev. Nyob rau xyoo 1600, tus kws tshawb fawb Fab Kis, Blaise Pascal, tau kawm txog qhov cuam tshuam ntawm cov kua dej. Pascal qhov kev tshawb pom tau txhawb kev tshawb fawb ntxiv. Los ntawm thaum ntxov 1900s, cov kws tshawb fawb paub tias kev kub siab tua qee yam kab mob. Thawj cov cuab yeej HPP hauv North America tau muab tso rau hauv 1996. HHP tseem hu ua "Pascalization" hauv kev hwm ntawm Pascal.
Puas yog Raw Dog Food Processed?
Los ntawm cov ntsiab lus nruj, cov zaub mov tiav yog txhua yam khoom noj uas tau hloov pauv los ntawm lub xeev qub. Cov zaub mov nyoos uas tau dhau los ntawm HPP yog technically "ua tiav."
Lo lus "ua tiav" raug saib tsis zoo hauv tib neeg cov zaub mov, vim nws feem ntau sib npaug nrog cov khoom noj muaj calorie ntau, cov zaub mov tsis tshua muaj. Yog lawm, dej qab zib thiab khoom qab zib tau ua tiav, tab sis yog li khov broccoli thiab cov kaus poom txiv duaj. Qhov kev xav tsis zoo ntawd tau nkag mus rau hauv khw muag khoom noj tsiaj thiab. Tag nrho cov lag luam muag khoom noj dev nyob rau hauv Teb Chaws Asmeskas tau ua tiav nyob rau hauv qee txoj kev-xws li siv cov cua sov los yog kev kub siab-kom muaj kev nyab xeeb rau kev noj.
Conclusion
Kev ua haujlwm siab tua cov kab mob phem uas tuaj yeem muaj nyob rau hauv cov nqaij nyoos thiab "mos siav" dev noj thiab kho. HPP yog lwm txoj hauv kev ua cov txheej txheem thermal uas siv cov cua sov kom tshem tawm cov kab mob. Qee qhov chaw xa mus rau HPP ua pascalization lossis txias pasteurization. Kev ua haujlwm siab tso cai rau cov tswv dev pub lawv cov tsiaj noj cov zaub mov nyoos thaum txo lawv txoj kev pheej hmoo ntawm Listeria, salmonella, thiab E. coli raug.
