Vim tias lawv yog kev huv thiab kev yooj yim, yasrau -} mus ntim rau zaub movmuaj ntau yam hauv tsev neeg thiab chaw tu ntaub ntawv. Txawm li cas los xij, muaj ntau yam kev txhawj xeeb txog kev hais tias cov ntaub ntawv xau txaus ntshai thaum lawv chilled. Kev nyab xeeb ntawm kev tawm hauv tub yees yasrau -} mus ntim rau zaub movYog tshuaj xyuas ntawm no, nrog rau tshwj xeeb them rau cov khoom muaj pes tsawg leeg, qhov mob kub thiab siv tau cov lus qhia siv tau. Txhawm rau pab cov qhua tuaj noj mov thiab cov chaw muab kev pabcuam zaub mov ua rau cov lus txiav txim siab, peb tseem muab cov lus qhia yuav ua li cas los ntsuas qhov ua tau zoo ntawm cov khoom sib chwv thiab ntxhiab.
1. Cov ntaub ntawv thiab kev nyab xeeb ntawm cov yas rau - mus ntim rau zaub mov
Kev nyab xeeb ntawmYas rau -}} mus ntim rau zaub movPob khawm ntawm hom yas siv thiab seb lawv puas ntsib zaub mov - tus qauv. Sib txawv tus cwj pwm txawv nyob rau hauv tub yees, thiab xaiv cov khoom zoo yog qhov tseem ceeb rau kev nyab xeeb zaubmov.
Cov Khoom Noj - B} Cov Plastics
Cov ntaub ntawv uas siv rau pov tseg rau - mus ntim rau cov khoom noj muaj xws li polypropylene (pystyrene (ps), thiab polylactic acid (PLA). Ntawm no yog qhov lawv ua nyob rau hauv tub yees (0-5 degree):
- Pp:Heev ruaj khov, ruaj, thiab tiv taus txias txias, ua rau nws zoo tagnrho rau cov tub yees rau {{kuas} mus ntim rau cov zaub mov.
- Tsiaj:Kuj ruaj khov nyob rau hauv tej yam mob txias, feem ntau siv rau cov zaub nyoos lossis dej txias vim nws txoj kev ntshiab thiab lub zog.
- PS:Ua Breittle ntawm tsawg kub thiab tej zaum yuav tawg, ua rau nws haum rau ntev {{}} lub teb tub yees.
- PLA:Kev xaiv biodegradable uas muaj kev nyab xeeb rau tub yees tab sis tsis zoo tagnrho rau kom khov vim tias muaj peev xwm tshwm sim.
Rau ob lub tsev thiab tsev noj mov siv, PP thiab tsiaj yog cov kev xaiv sab saum toj rau -}}}} pa luam rau zaub mov vim yog lawv txias tsis kam thiab kev nyab xeeb.
Cov ntawv pov thawj kev nyab xeeb kev nyab xeeb
Txhawm rau -}} mus ntim rau cov zaub mov ntawm cov koom haum siab tshaj plaws yuav tsum tau muab ntawv pov thawj los ntawm cov koom haum xws li FDA, LFGB, lossis SGS. Cov ntawv pov thawj ua pov thawj rau cov thawv kom haum rau kev tuav cov zaub mov nyob hauv ntau qhov xwm txheej, nrog rau tub yees. Txhawm rau lav ua raws li, nrhiav cov ntawv lo rau hauv qab ntawm cov zaub mov rau}}} tso cov khoom noj "lossis" PP5, "uas txhais cov khoom siv PP. Txawm nyob rau hauv qhov chaw cia khoom txias, kev pheej hmoo ntawm kev tsiv teb tsaws chaw yog txo qis ntawm cov thawv muaj ntawv pov thawj.
Kev ruaj khov nyob rau hauv tub yees
Feem ntau, tub yees txias ntawm 0℃thiab 5℃tsis tshua muaj kev hloov pauv molecular nyob rau hauv polymers. Txias txias tswj cov qauv khoom siv, hauv kev sib piv rau kev kub siab uas tuaj yeem ua rau cov tshuaj polymers kom tso cov tshuaj ntxuav kom zoo li cov carbonations lossis bisphenol a (BPA). Thaum cov khoom noj yog tub yees, kom muaj ntawv pov thawj rau - mus ntim tsis zoo rau cov tshuaj muaj kev phom sij. Txawm li cas los xij, tej zaum yuav muaj tshuaj migration me ntsis nyob rau hauv tsis zoo- cov thawv zoo lossis cov uas khov thiab yaj feem ntau. Kev rov siv dua rau - Koj mus ntim rau cov zaub mov rau ncua sijhawm ntev yuav tsum tau zam rau txo kev phom sij.
2. Ua rau {{{-}} mus ntim rau cov zaub mov muab cov tshuaj ua kom zoo nkauj uas ua rau cov pa tawm hauv tub yees?
Cov ntaub ntawv pov thawj scientific qhia tias tub yees ua kev pheej hmoo tsawg tsawg rau kev ua si tshuaj lom neeg los ntawm high {{1}- mus ntim rau cov zaub mov. Qhov chaw kub qis qeeb qeeb molecular kev ua si, txo qhov ntxim nyiam ntawm cov tshuaj muaj teeb meem uas tau tsiv mus ua zaub mov. Txawm li cas los xij, qee yam tseem ceeb tuaj yeem ua rau muaj kev pheej hmoo loj:
- Tsawg - Cov Khoom Siv Zoo:Cov ntim tau ua los ntawm kev ua dua tshiab lossis tsis {{} zaub mov}
- Kev puas tsuaj ntawm lub cev:Tawg lossis hnav rau {-}} mus ntim rau cov zaub mov yuav tso cov quav tshuaj yog tias cov yas av.
- Acidic lossis Fatty Khoom Noj:Thaum tsawg dua ntawm qhov teeb meem nyob rau hauv tub yees, acidic lossis cov zaub mov muaj roj (piv txwv li cov khoom siv lws suav lossis muaj peev xwm ua rau muaj kev sib tua me me.
Txhawm rau kom muaj kev nyab xeeb, ib txwm siv ntawv pov thawj, zaub mov {{} {1} {{{{2} - Cov thawv zoo rau lub sijhawm ntev.
3. Txheeb xyuas rau -}} mus ntim rau cov zaub mov los ntawm kov thiab tsw
Nrog rau kev paub txog cov neeg siv kev nyab xeeb ntawm kev nyab xeeb ntawm zaub mov, nws yog qhov tseem ceeb kom paub ntsuas qhov zoo ntawm {}}} mus ntim rau zaub mov sai. Siv kov thiab tsw, koj tuaj yeem ntsuas ntsuas seb puas muaj ib lub thawv muaj kev nyab xeeb rau tub yees lossis kev siv dav dav.
Txheeb xyuas los ntawm kov
Cov tactile zoo ntawm rau -}} mus ntim rau cov zaub mov tuaj yeem qhia tau ntau yam txog lawv qhov zoo:
- √ Nto du:Siab - Cov thawv zoo hnov du, nrog cov npoo huv thiab tsis muaj burrs. Ntxhib lossis cov chaw nplaum feem ntau qhia tias qis-} qib cov khoom lossis impurities.
- √ Thickness thiab kev txhawb nqa:Nias lub thawv ntim maj mam. Zoo rau {-}} mus ntim rau cov khoom noj, tshwj xeeb yog ua los ntawm pp lossis tsiaj, muaj cov khaub ncaws tuab thiab tiv thaiv. Cov nyias nyias lossis tsis sib xws yuav vau lossis tawg, ua kom muaj kev nyab xeeb.
- Tactile liab chij:Yog tias lub taub ntim hnov cov nplej, dhau los yog lo, nws yuav muaj cov plastics lossis cov quav ntxiv uas tuaj yeem ua rau muaj kev pheej hmoo, tshwj xeeb yog rhuab tom qab tub yees.
Txheeb xyuas los ntawm tsw
Qhov tsis hnov tsw yog lwm qhov qhia tau zoo ntawm qhov ua tau zoo rau -}} mus ntim rau cov khoom noj:
- √ Tsis muaj tsw ntxhiab lossis mob meHigh - Cov thawv ntim tau zoo yuav tsum yog yuav luag tsis muaj ntxhiab tsw lossis muaj kev tsaus muag, nruab nrab dawb tsw. Qhov no qhia tias lawv tau ua los ntawm cov ntshiab, zaub mov-} cov khoom siv qib.
- Cov Cim Ceeb Toom:Tsis txhob ntim nrog qaub, hlawv, lossis cov ntxhiab tsw ntxhiab. Cov tsw no tej zaum yuav teeb liab:
- Qaub tsw:Laus laus yas lossis rov ua cov khoom siv.
- Hlawv Tshuaj Noj:Tshuaj lom neeg decomposition los ntawm tsawg - zoo ntau lawm.
- Cov ntxhiab tsw ntxhiab tsw:Cov tshuaj tsw qab rau daim npog impurities, uas tuaj yeem qhia tsis yog {}} {1} {1} {1}-
- Kev Ntsuam Cua Kub:Kom paub meej tias kev nyab xeeb, microwave ib lub thawv khoob rau ib feeb. Yog tias nws emits muaj cov ntxhiab tsw muaj zog, nws yuav tsis nyab xeeb rau cov khoom noj khoom haus, txawm nyob rau hauv tub yees.
By using touch and smell, you can quickly identify substandard to-go containers for food and avoid potential health risks.
