Sucralosethiab aspartame yog ob qho tib si hluavtaws sweeteners, tab sis muaj qhov sib txawv tseem ceeb hauv lawv cov qauv tshuaj thiab cov khoom.
1. Cov qauv tshuaj
Aspartame yog tsim los ntawm ntuj amino acids Phenylalanine, Aspartic acid thiab Methanol, thiab nws cov tshuaj formula C14H18N2O5. Aspartame decomposes rau hauv cov khoom xws li phenylalanine, aspartic acid, thiab methanol hauv dej, yog li nws tsis tuaj yeem siv rau cov cua sov hauv qhov kub thiab txias los yog khaws cia ntev.
Sucralose yog ib hom tshiab ntawm cov khoom qab zib siab siv tau los ntawm chlorination ntawm sucrose. Nws cov qauv tshuaj zoo ib yam li sucrose, tab sis qee qhov hydrogen atoms hloov los ntawm chlorine. Nws cov tshuaj formula yog C12H19Cl3O8. Vim tias cov tshuaj chlorine atoms hauv nws cov molecule ua rau nws tsis tshua muaj kev puas tsuaj thiab nqus los ntawm lub cev enzymes, sucralose tsis cuam tshuam rau cov ntshav qab zib thiab insulin tso tawm.
2. Xwm
qab zib
Qhov qab zib ntawm aspartame yog kwv yees li 200 npaug ntawm sucrose, thaum lub qab zib ntawm sucralose tseem siab dua, ncav cuag li 600 npaug ntawm sucrose. Hauv kev siv tiag tiag, txij li sucralose yog qab zib dua, yuav tsum tau noj tsawg dua kom ua tiav qhov qab zib.
thermal stability
Aspartame tsis ruaj khov rau qhov kub thiab txias thiab yooj yim decomposes los tsim cov khoom tsis ruaj khov xws li phenylalanine thiab aspartic acid, yog li nws tsis tsim nyog rau kev ua zaub mov lossis kev cia ntev ntev hauv qhov kub thiab txias.
Txawm li cas los xij, sucralose yog qhov ruaj khov nyob rau hauv qhov kub thiab txias thiab yuav tsis tsim cov tshuaj phem, yog li nws tuaj yeem siv rau hauv kev ua zaub mov nyob rau hauv qhov kub thiab txias xws li ci thiab boiling.
muaj peev xwm metabolic
Aspartame muaj lub siab solubility thiab tuaj yeem nqus tau sai los ntawm tib neeg lub cev. Tom qab metabolized los ntawm daim siab nyob rau hauv lub cev, nws tsim methyleneation thiab oxidative decomposition khoom. Cov metabolites sib xws hauv lub cev tsis muaj methanol. Tsis tas li ntawd, aspartame muaj qhov qab zib siab thiab siv me me, yog li nws yuav tsis cuam tshuam kev noj qab haus huv raws li kev noj haus ib txwm muaj.
Sucralose tsis tuaj yeem zom thiab nqus tau hauv tib neeg lub cev, thiab feem ntau ntawm nws tau tawm hauv cov zis, uas ruaj khov thiab nyab xeeb dua li aspartame. Txawm li cas los xij, hauv cov koob tshuaj ntau heev, sucralose kuj tseem tuaj yeem ua rau lub siab thiab lub plab puas.
Epilogue
Piv txwv li, txawm hais tias aspartame thiab sucralose yog ob qho tib si hluavtaws cov khoom qab zib, muaj qhov sib txawv tseem ceeb hauv lawv cov qauv tshuaj thiab cov khoom. Hauv kev siv tswv yim, nws yuav tsum xaiv cov khoom qab zib siv raws li cov khoom noj sib txawv thiab cov xwm txheej ntawm daim ntawv thov kom ua tiav cov txiaj ntsig zoo thiab tiv thaiv kev noj qab haus huv ntawm cov neeg siv khoom.
