Puas yog aluminium foil hnab muaj kev nyab xeeb?
Taw qhia:
Aluminium foil hnab tau txais kev muaj koob meej hauv ntau qhov kev lag luam vim lawv cov khoom tshwj xeeb thiab ntau yam. Lawv feem ntau yog siv los ntim cov khoom noj khoom haus, tshuaj, khoom siv hluav taws xob, thiab lwm yam ntaub ntawv rhiab heev. Txawm li cas los xij, muaj kev txhawj xeeb txog lawv txoj kev nyab xeeb thiab kev pheej hmoo ntawm kev noj qab haus huv. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog kev nyab xeeb ntawm aluminium foil hnab thiab tshuaj xyuas cov pov thawj tshawb fawb los txiav txim seb lawv puas muaj kev nyab xeeb rau kev siv.
Nkag siab txog Aluminium Foil Bags:
Aluminium ntawv ci hnab yog tsim los ntawm laminating nyias cov ntawv ntawm txhuas mus rau ib tug saj zawg zog yas zaj duab xis. Kev sib xyaw ua ke ntawm cov ntaub ntawv no ua rau muaj kev cuam tshuam rau cov dej noo, tshav ntuj, oxygen, thiab lwm yam sab nraud uas tuaj yeem degrade lossis paug cov khoom ntim. Cov hnab ntim khoom feem ntau yog siv los ntim cov khoom puas tsuaj thiab tiv thaiv lawv los ntawm kev lwj lossis kev puas tsuaj.
Kev Sib Tham Txog Kev Nyab Xeeb:
Muaj ob qhov tseem ceeb ntawm kev txhawj xeeb thaum tham txog kev nyab xeeb ntawm cov hnab ntawv aluminium - kev sib cuag ncaj qha nrog cov zaub mov thiab qhov muaj peev xwm tso tawm cov tshuaj lom.
Tiv tauj ncaj qha nrog zaub mov:
Aluminium yog cov khoom tsis muaj tshuaj lom thiab tsis muaj zog, uas txhais tau hais tias nws tsis hnov mob nrog zaub mov lossis hloov nws saj. Ntau lub koom haum tswj hwm, suav nrog US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA), tau pom tias cov hnab ntawv txhuas muaj kev nyab xeeb rau kev sib cuag nrog zaub mov. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom noj acidic lossis qab ntsev yuav ua rau cov txhuas nkag mus rau hauv cov zaub mov, tshwj xeeb tshaj yog thaum cua sov. Yog li ntawd, nws raug nquahu kom tsis txhob siv cov hnab aluminium foil rau cov khoom noj uas muaj kua qaub lossis cov ntsev siab, tshwj xeeb tshaj yog thaum ua noj lossis rov ua kom sov.
Muaj peev xwm tso tawm cov tshuaj lom:
Ib qho ntawm cov kev txhawj xeeb tseem ceeb ntawm cov hnab ntawv aluminium yog qhov muaj peev xwm tso tawm cov tshuaj lom, tshwj xeeb tshaj yog thaum lawv raug kub siab. Aluminium ntawv ci muaj qhov melting point tsawg, nyob ib ncig ntawm 660 degrees Celsius (1220 degrees Fahrenheit), uas zoo tshaj qhov kub ua noj. Txawm li cas los xij, yog tias cov ntawv ci tuaj rau hauv kev sib cuag ncaj qha nrog cov nplaim taws qhib lossis qhov chaw kub heev, nws tuaj yeem yaj lossis ntes hluav taws, muaj peev xwm tso cov pa phem.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum tshav kub kub aluminium ntawv ci tuaj yeem tso cov txhuas me me rau hauv cov khoom noj, cov kev tshawb fawb tau pom tias cov qib feem ntau zoo dua li cov kev txwv kev nyab xeeb uas tau teev tseg los ntawm lub koom haum tswj hwm. Tsis tas li ntawd, tib neeg lub cev ib txwm tshem tawm me me ntawm txhuas los ntawm ntau yam excretory mechanisms.
Lub luag haujlwm ntawm Cov Txheej Txheem Ntim:
Txhawm rau kom muaj kev nyab xeeb ntawm cov khoom ntim, ntau cov kev cai thiab cov txheej txheem tau tsim nyob thoob ntiaj teb. Cov kev cai no tau txwv cov khoom uas tuaj yeem txav los ntawm cov khoom ntim rau hauv cov zaub mov thiab tsim los tiv thaiv pej xeem kev noj qab haus huv. Aluminium foil hnab siv rau ntim khoom noj yuav tsum ua raws li cov cai no kom pom tau tias muaj kev nyab xeeb rau kev siv.
Piv txwv li, FDA hauv Tebchaws Meskas tswj xyuas cov ntaub ntawv ntim khoom raws li Txoj Cai Tswjfwm Ntiag Tug (CFR) Title 21. Tshooj 174.5 ntawm CFR qhia txog cov xwm txheej hauv qab uas txhuas tuaj yeem siv nyab xeeb hauv kev ntim khoom noj. Ib yam li ntawd, EFSA hauv Tebchaws Europe tau tsim cov kev cai tshwj xeeb, xws li European Commission Regulation (EC) No 10/2011, uas tau teev tag nrho cov kev txwv kev tsiv teb tsaws chaw rau cov khoom siv los tiv thaiv cov khoom noj.
Alternatives rau Aluminium Foil Bags:
Thaum lub hnab aluminium foil tau siv dav, ntau qhov kev xaiv tau tshwm sim nyob rau xyoo tas los no. Cov kev xaiv no tsom mus daws cov kev txhawj xeeb txog kev nyab xeeb cuam tshuam nrog aluminium foil hnab thiab muab kev xaiv kom ruaj khov dua. Qee qhov kev xaiv nrov muaj xws li:
1. Cov ntawv ntim cov ntawv: Cov hnab ntawv nrog cov roj-resistant coatings lossis cov qauv laminated tuaj yeem hloov tau cov hnab ntawv aluminium rau qee yam kev siv. Lawv feem ntau suav hais tias muaj kev nyab xeeb rau kev sib cuag zaub mov ncaj qha thiab ua rau muaj kev pheej hmoo ntawm ib puag ncig tsawg.
2. Biodegradable thiab compostable cov ntaub ntawv: ntim cov ntaub ntawv ua los ntawm cov nroj tsuag-raws li polymers los yog lwm yam biodegradable tshuaj tau txais koob meej. Cov ntaub ntawv no muab cov khoom sib piv rau cov hnab aluminium foil thaum ua tus phooj ywg zoo dua.
3. BPA-dawb yas zaj duab xis: Bisphenol A (BPA) yog ib yam tshuaj siv nyob rau hauv ib co yas zaj duab xis uas tau ua rau muaj kev txhawj xeeb txog nws cov kev pheej hmoo ntawm kev noj qab haus huv. Kev xaiv rau BPA-dawb yas zaj duab xis tuaj yeem txo cov kev txhawj xeeb no thaum tuav cov txiaj ntsig ntawm kev ntim khoom yooj yim.
Xaus:
Hauv kev xaus, aluminium foil hnab feem ntau suav hais tias muaj kev nyab xeeb rau kev siv ntim khoom noj thiab lwm yam khoom rhiab heev. Txawm hais tias muaj kev txhawj xeeb txog kev sib cuag ncaj qha nrog cov khoom noj acidic lossis qab ntsev thiab muaj peev xwm tso tawm cov tshuaj lom thaum raug kub hnyiab, cov pov thawj tshawb fawb pom tau tias qhov kev pheej hmoo tsawg tsawg thiab feem ntau nyob rau hauv cov kev cai txwv. Txawm li cas los xij, nws yog ib txwm xav kom ua raws li cov lus qhia tshwj xeeb muab los ntawm lub koom haum tswj hwm thiab xav txog lwm txoj hauv kev uas haum rau cov ntim tshwj xeeb lossis kev txhawj xeeb ntawm ib puag ncig.
