Acrylamide yog qhov tshuaj lom neeg muaj kev phom sij siv los ua cov polyacrylamide polymer siv hauv kev tsim cov yas ntim.

Ua mob los ntawm acrylamide

Raws li cov kev tshawb fawb ntau, acrylamide muaj cov tshuaj lom muaj zog rau hauv cov leeg hlwb, ob qho tib si hauv kev sim rau tib neeg thiab tib neeg ua haujlwm hauv thaj chaw uas tau raug. acrylamideCov. Acrylamide yog cov neeg ua pov thawj carcinogen hauv cov tsiaj sim, ua rau cov qog ntshav hauv ntau cov kabmob.

Tsis muaj pov thawj tshwm sim los ntawm tib neeg.

Nyob rau xyoo 1994, Lub Koom Haum International rau Kev Tshawb Fawb Kev Khees Xis (Acrylamide) tau tshaj tawm cov tshuaj "acrylamide" uas yog "cuam tshuam rau tib neeg mob carcinogen."

Txais yuav koob tshuaj acrylamide

Raws li International Agency for Research on Cancer, acrylamide tuaj yeem ua rau muaj kev hloov pauv hauv noob neej thiab muaj cov roj carcinogenic ua rau tib neeg lub cev.

Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv tau teeb tsa qhov siab tshaj plaws tso cai ntawm nws cov dej siab - 0.1 mcg rau 1 litre.

Hauv Tebchaws Yelemees, piv txwv, cov tuam txhab ntim cov ntawv ntim khoom yas yog lub luag haujlwm los xyuas kom meej tias, thaum muaj kev sib cuag nrog cov hnab ntim khoom noj, lawv tsis muaj ntau tshaj 10 mcg ntawm acrylamide rau 1 kg ntawm khoom.

Qhov chaw ntawm acrylamide

Cov khob cij thiab hmoov nplej, mov, nqaij, nqaij qos ntoo, ntses thiab ntau yam zaub mov noj tau ua tiav rau ntawm qhov kuaj pom acrylamideCov. Cov kws tshawb fawb tau pom tias cov khoom tsim los ntawm cov qos yaj ywm uas muaj cov hmoov txhuv nplej siab thiab ntau yam khoom noj yog qhov tseeb txhaws nrog cov carcinogen no.

Cov qauv txuas ntxiv uas cov kws tshawb fawb pom tau yog tias cov khoom no tau dhau los ua kev kho cua sov saum toj no 120 degrees - ci, ci, kib.

Cov ntsiab lus siab ntawm acrylamide los ntawm cov amino acid asparagine, uas thaum rhuab los ntawm 120 txog 185 degrees thiab ntau dua tig mus rau hauv xws li cov teeb meem sib tov.

Nws yuav tsum raug sau tseg ntawd acrylamide nws tsis muaj nyob hauv cov khoom noj tsuas yog vim cov neeg tsim khoom lom los ntawm tib neeg lossis tsis ua raws cov txheej txheem thev naus laus zis. Yog tias koj kib qos yaj ywm hauv tsev nyob hauv lub fryer, qhov ntau npaum li cas acrylamide yuav tib yam li hauv kib qos yaj ywm hauv khw noj mov. Txhawm rau kom tsis txhob muaj qhov phom sij ntawm acrylamide, cov zaub mov yuav tsum tau muab rhaub lossis muab cub.

Rov qab muab cov zaub mov kib rau hauv lub lauj kaub lossis qhov cub kuj tseem tsis pom zoo, vim tias qhov no yuav muaj cov ntsiab lus acrylamide ntau dua.

Lwm qhov chaw - Acrylamide yog tshuaj lom neeg lom uas polymerizes tau yooj yim, yog li nws tau siv rau hauv cov khoom lag luam polyacrylamide.

Polyacrylamide, ntawm lwm qhov, pom ntau daim ntawv thov - raws li cov txheej txheem dej ua kom huv hauv cov dej haus, hauv kev sib txuas ntawm cov tshuaj pleev, hauv tshuaj pleev ib ce, hauv kev lag luam ntawv. Cov pa luam yeeb kuj tseem yog ib qho ntawm acrylamide.

Cov European Commission qhov kev pom zoo los soj ntsuam cov theem ntawm acrylamide hauv cov zaubmov pib thaum lub Tsib Hlis 2007, Tsoomfwv Cov Tswv Cuab yuav tsum saib xyuas cov theem no txhua xyoo.

Cov pawg ntawm cov khoom noj uas poob rau hauv cov npe dub yog qos yaj ywm kib thiab kib kib; qos cov khoom lag luam npaj rau hauv tsev; khob cij, mov ci thiab cereals; kom tsis muaj menyuam noj tej khoom noj thiab menyuam mos ua noj, thiab lwm yam.

Raws li Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv, tsej muaj 1,343 mcg / kg; hauv cov khoom noj txom ncauj qhuav 150 mcg / kg; hauv french fries 330 mcg / kg; hauv pobkws pob kws 167 μg / kg; hauv khob cij, ci thiab ncuav 142 mcg / kg; hauv roasted qaib 52 mcg / kg.

Txo cov qib acrylamide

Nws tau pom tseeb tias nws tsis txaus ntseeg txog kev faus cov khoom qab zib hauv khw noj mov, vim tias txawm tias siav hauv tsev, lawv tseem muaj kev phom sij.

Cov lus qhia ntawm cov kws kho mob hauv Tebchaws Europe rau cov pejxeem yog txhawm rau txhaws cov khoom kom txog thaum Golden, tsis yog xim av. Qhov xwm txheej yuav raug xwm txheej tshwj xeeb yog tias lub tais hlawv. Cov kev pom zoo tom ntej yog kom tsis txhob noj mov ci raws li txoj kev ua noj ua haus.

Kev qhob cij muab cov txiaj ntsig ntxiv uas ua rau thaum kub acrylamideCov. Yog tias ua tau, hloov ci nrog ua noj. Cov zaub mov ceev yuav tsum muab txoj hauv kev rau cov khoom ntuj tsim.
