First of all, let's clarify that cov luteinthiab lutein esters yog ob yam sib txawv, tab sis lawv tsis txawv kiag li. Qhov no tsuas yog ib qho teeb meem ntawm kev txheeb xyuas. Daim ntawv tseem ceeb ntawm lutein hauv cov nroj tsuag ntuj yog lutein esters. Yog li, dab tsi yog qhov txawv ntawm lutein thiab lutein esters?
(A: Lutein, B: Lutein Esters)
1. Khoom
Lutein yog ib tsob nroj lutein, uas yog ib qho muaj zog antioxidant.
Lub ntsiab ntawm lutein ester yog lutein dipalmitate, uas muaj nyob rau hauv tag nrho cov -trans molecular configuration. Nws yog carotenoid thiab fatty acid.
2. Txoj kev nqus
Lutein feem ntau yog tau los ntawm kev noj haus txhua hnub thiab tuaj yeem nqus tau ncaj qha rau hauv cov hnyuv los ntawm tib neeg lub cev.
Txawm li cas los xij, lutein esters nkag mus rau tib neeg lub cev thiab thawj zaug decomposed, thiab tom qab ntawd hloov mus rau hauv lutein thiab ces absorbed los ntawm tib neeg lub cev.
3. Kev ruaj ntseg
Nyob rau hauv cov txheej txheem ntawm kev khaws cia thiab noj, kev siv tus nqi ntawm lutein yuav txo qis heev vim qhov kev hloov ntawm lub teeb, kub thiab PH nqi. Nws lub teeb thiab thermal stability tsis zoo li lutein ester. Lutein esters ruaj khov dua hauv kev cia thiab noj vim lawv cov qauv molecular. Tom qab ntawd qhov kev siv ntawm lutein kuj tsawg.
4. Muaj nuj nqi
Lutein muaj kev tiv thaiv kev laus -. Nws tuaj yeem tiv thaiv kab mob plawv thiab lwm yam kab mob. Lutein kuj muaj ntau carotenoids, yog li nws kuj muaj kev tiv thaiv qhov muag. Lutein tsis sib npaug rau lutein ester. Lutein ester yuav tsum tau zom rau hauv lutein ua ntej nws tuaj yeem nqus tau, thiab lutein tuaj yeem nqus tau ncaj qha. Feem ntau hais lus, kev lag luam tus nqi ntawm lutein yog siab dua li ntawm lutein ester.
5. Acid Resistance
Lutein muaj cov kua qaub tsis zoo, thiab nws muaj feem ntau yuav yaj los ntawm plab acid tom qab noj ncaj qha thiab cuam tshuam rau tib neeg kev nqus.
The consumption and loss of lutein esters are very low when they pass through the stomach after eating and do not affect the human body's absorption.
Qhov twg zoo dua?
Daim ntawv twg zoo dua tam sim no tseem tsis paub meej. Cov kev tshawb fawb tau pom tias tom qab nojcov luteinlos yog lutein ester tsis tu ncua rau 3 lub hlis, tsis muaj qhov sib txawv tseem ceeb hauv qhov muag macular pigment ntom thiab ntshav lutein concentration. Txawm li cas los xij, kom ua tiav tib cov ntshav lutein concentration, lutein ester koob tshuaj yuav tsum tau noj yog ntau dua li cov tshuaj lutein.
