Kev nyab xeeb ntawm cov pigments organic feem ntau nyob ntawm lawv cov tshuaj muaj pes tsawg leeg thiab npaj siv. Feem ntau, cov organic pigments raug suav hais tias muaj kev nyab xeeb, tshwj xeeb tshaj yog thaum lawv tau los ntawm cov khoom siv ntuj tsim los yog tsim los ua kom tau raws li cov qauv kev cai rau cov ntawv thov tshwj xeeb. Nov yog qee cov ntsiab lus tseem ceeb hais txog kev nyab xeeb ntawm cov organic pigments:
- Ntuj qhov chaw: Ntau cov organic pigments tau muab los ntawm cov nroj tsuag, tsiaj txhu, thiab cov zaub mov uas tau siv rau ntau pua xyoo hauv ntau yam kab lis kev cai thiab kev kos duab. Piv txwv xws li indigo los ntawm cov nroj tsuag thiab carmine los ntawm cochineal kab. Cov pigments ntuj no feem ntau suav tias yog kev nyab xeeb, tshwj xeeb tshaj yog hauv cov ntawv thov xws li zaub mov thiab tshuaj pleev ib ce.
- Synthetic Organic Pigments: Cov no yog tsim los ntawm cov tshuaj synthesis thiab feem ntau yog tsim los ua kom zoo los yog txhim kho cov khoom ntawm ntuj pigments. Kev tswj hwm lub cev xws li FDA (Food and Drug Administration) thiab European Food Safety Authority (EFSA) soj ntsuam thiab pom zoo cov xim hluavtaws siv rau hauv cov zaub mov, tshuaj pleev ib ce, thiab tshuaj kom ntseeg tau tias lawv tsis muaj tshuaj lom thiab nyab xeeb rau tib neeg siv.
- Kev Tswj Xyuas Kev Tswj Xyuas: Organic pigments siv nyob rau hauv cov neeg siv khoom yuav tsum tau nruj me ntsis kev cai. Piv txwv li, hauv Tebchaws Meskas, FDA tswj cov xim ntxiv rau hauv cov zaub mov, tshuaj, tshuaj pleev ib ce, thiab khoom siv kho mob kom ntseeg tau tias lawv muaj kev nyab xeeb rau lawv txoj kev siv. Cov kev tswj hwm zoo sib xws muaj nyob hauv lwm lub tebchaws thiab cheeb tsam.
- Muaj peev xwm txhawj xeeb: Txawm hais tias lawv muaj kev nyab xeeb dav dav, qee cov organic pigments tuaj yeem ua rau muaj kev tsis haum tshuaj lossis cov tawv nqaij rhiab heev rau qee tus neeg, tshwj xeeb tshaj yog thaum siv tshuaj pleev ib ce lossis cov khoom tu tus kheej. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias tsis yog txhua yam khoom ntuj tsim muaj kev nyab xeeb; Piv txwv li, qee cov xim ntuj tuaj yeem ua rau muaj tshuaj lom lossis carcinogenic.
- Environmental Impact: Organic pigments feem ntau suav hais tias yog ib puag ncig zoo dua piv rau cov xim inorganic uas yuav muaj cov hlau hnyav. Txawm li cas los xij, qhov cuam tshuam ib puag ncig ntawm kev tsim cov khoom siv hluavtaws tuaj yeem sib txawv nyob ntawm cov txheej txheem tsim khoom thiab pov tseg cov tshuaj pov tseg.
- Cov lus qhia siv: Kev nyab xeeb kuj nyob ntawm kev siv kom raug. Piv txwv li, pigments npaj rau cov ntawv thov kev lag luam yuav tsum tsis txhob siv rau hauv cov khoom noj lossis tshuaj pleev ib ce tshwj tsis yog tias pom zoo rau cov kev siv. Ib txwm ua raws li cov chaw tsim khoom cov lus qhia thiab cov lus pom zoo tswj xyuas kom muaj kev nyab xeeb ntawm daim ntawv thov.
Hauv cov ntsiab lus, cov organic pigments feem ntau muaj kev nyab xeeb thaum siv kom tsim nyog thiab ua raws li cov qauv kev cai. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab txog tus kheej rhiab heev thiab muaj feem cuam tshuam rau ib puag ncig, thiab ua raws li cov lus qhia kom muaj kev nyab xeeb hauv lawv cov ntawv thov tshwj xeeb.
