Kev piav qhia
Aspartame yog ib hom khoom qab zib, belongs rau cov amino acid dipeptide derivatives, los ntawm cov kws kho mob tsim cov tshuaj rwj pom nyob rau xyoo 1965. Nrog rau cov tshuaj tsawg, siab qab zib (qab zib yog 150 txog 200 npaug ntawm sucrose), saj zoo, txhim khu tsw ntawm citrus. thiab lwm cov txiv hmab txiv ntoo thiab txo cov cua sov tsis tsim cov kab mob hauv cov hniav, toxicity tshaj saccharin thiab lwm yam khoom qab zib cov khoom zoo, yog dav siv rau cov dej haus, cov khoom noj ntshav qab zib thiab qee cov zaub mov noj qab haus huv, peb lub neej niaj hnub haus cov mis nyuj cola ib zaug uas muaj cov khoom.
Aspartame nyob rau hauv cov txheej txheem metabolic hauv lub cev thiab cov khoom lag luam degradation tseem ceeb yog phenylalanine, methanol thiab aspartic acid, tsis nkag mus rau hauv cov ntshav ncig, thiab tsis sib sau hauv lub cev, zaub mov rau kev noj qab haus huv tsis muaj teeb meem.Tab sis vim muaj cov kab mob metabolic nyob rau hauv cov neeg mob uas muaj phenylketonuria (PKU), ntau lub cev phenylalanine tuaj yeem cuam tshuam nws txoj kev loj hlob, yog li cov neeg mob uas muaj tus kab mob no cuam tshuam ntxiv aspartame.
Aspartame yuav daws thiab poob qab zib tom qab cua sov ntev thiab nws tseem ruaj khov ntawm qhov kub thiab txias thiab qis dua PH tus nqi 3 txog 5, thiab nws tsim nyog rau cov dej haus tshiab thiab cov zaub mov tsis muaj cua sov.
Muaj nuj nqi
(1) Aspartame yog lub ntuj ua haujlwm oligosaccharides, tsis muaj cov hniav lwj, ntshiab qab zib, tsis muaj dej noo, tsis muaj qhov tshwm sim nplaum.
(2) Aspartame muaj cov qab zib ntshiab thiab zoo sib xws nrog sucrose, muaj qab zib qab zib, tsis muaj iab tom qab saj thiab xim hlau.
(3) Aspartame tuaj yeem siv rau hauv ncuav mog qab zib, biscuits, qhob cij, npaj cawv, dej khov, popsicles, dej qab zib, khoom qab zib, thiab lwm yam. Tsis tuaj yeem ua rau cov ntshav qab zib ntau dua rau cov neeg mob ntshav qab zib.
(4) Aspartame thiab lwm yam khoom qab zib los yog sib tov ntawm sucrose muaj kev sib koom ua ke, xws li 2% mus rau 3% ntawm aspartame, tuaj yeem npog qhov tsis zoo ntawm saccharin.
Daim ntawv thov
Aspartame yog nyob ib ncig ntawm 180-200 lub sij hawm sweeter dua sucrose (cov lus qab zib).Vim tias cov cuab yeej no, txawm tias aspartame tsim tau plaub kilocalories ntawm lub zog ib gram (17 kJ / g) thaum metabolized, qhov ntau ntawm aspartame xav tau los tsim cov qab zib yog li me me uas nws cov caloric pab yog negligible.Qhov qab zib ntawm aspartame kav ntev dua li ntawm sucrose, yog li nws feem ntau sib xyaw nrog lwm cov khoom qab zib xws li acesulfame potassium los tsim cov saj tag nrho zoo li qab zib.
Aspartame yog siv los ua cov khoom qab zib hnyav hauv cov khoom haus, khoom noj khoom haus, thiab cov khoom qab zib saum rooj, thiab hauv kev npaj tshuaj suav nrog cov ntsiav tshuaj, hmoov sib tov, thiab cov vitamin npaj.Nws txhim kho cov tshuab tsw qab thiab tuaj yeem siv los npog qee qhov tsis hnov tsw yam ntxwv.Txawm li cas los xij, hauv kev xyaum, qhov me me ntawm aspartame noj muab cov khoom noj tsawg tsawg.
