Qhov sib txawv tseem ceeb ntawm aspartame thiab saccharin yog tias aspartame yog 200 npaug sweeter dua saccharin.
Aspartame thiab saccharin yog cov khoom qab zib. Cov no muaj txiaj ntsig hauv kev tsim cov khoom qab zib rau cov khoom noj. Aspartame yog ib qho organic compound uas muaj cov tshuaj formula C14H18N2O 5, thaum saccharin muaj cov tshuaj formula C7H5NO3S.
Aspartame yog dab tsi?
Aspartame yog ib qho organic compound uas muaj cov tshuaj formula C
14H18N2O 5 Nws tuaj yeem piav qhia tias yog cov khoom qab zib uas tsis yog saccharide uas yog kwv yees li 200 npaug sweeter dua sucrose. Tsis tas li ntawd, nws feem ntau yog siv los hloov cov suab thaj hauv kev lag luam khoom noj rau cov khoom noj thiab dej haus. Peb tuaj yeem lees paub aspartame yog ib qho ntawm cov khoom xyaw ua zaub mov nruj tshaj plaws.
Tus nqi ntawm aspartame peb xav tau los tsim cov qab zib me me; Yog li ntawd, cov calories uas nws tuaj yeem ua tau yog qhov tsis txaus ntseeg. Txawm li cas los xij, nws tseem tuaj yeem tsim 4 kcal ntawm lub zog ib gram. Lub qab zib saj ntawm aspartame yog txawv ntawm cov suab thaj qab zib thiab ntau lwm yam sweeteners. Piv nrog rau qhov qab zib ntawm sucrose, qhov qab zib ntawm aspartame kav ntev. Yog li ntawd, peb tuaj yeem muab nws nrog lwm cov khoom qab zib xws li acesulfame potassium kom tau txais cov qab zib uas zoo ib yam li qab zib.
Zoo li lwm yam peptides, aspartame tuaj yeem hydrolyze rau hauv nws cov amino acids hauv cov xwm txheej ntawm qhov kub siab lossis pH siab. Yog li, aspartame tsis tsim nyog rau lub hom phiaj ci, thiab nws tseem tuaj yeem degrade cov khoom uas muaj pH siab, uas yuav tsum tau rau lub txee ntev dua. Ntxiv mus, aspartame tsis ruaj khov nyob rau hauv tshav kub, uas tuaj yeem zam los yog txo qis rau qee qhov los ntawm encasing nws hauv cov rog lossis hauv m altodextrin.
Saccharin yog dab tsi?
Saccharin muaj cov tshuaj formula C7H5NO3S thiab yog hom ntawm cov khoom qab zib uas tsis muaj zaub mov muaj zog. Cov tshuaj no yog hais txog 300-400 lub sij hawm sweeter dua sucrose. Ntxiv mus, nws muaj iab los yog xim hlau tom qab saj. Ib qho aftertaste tuaj yeem txhais tau tias yog qhov kev siv ntawm cov khoom noj tshwj xeeb uas peb yuav pom tau tam sim tom qab tshem tawm cov khoom noj ntawm lub qhov ncauj. Qhov no iab los yog xim hlau tom qab saj ntawm saccharin tuaj yeem saj feem ntau ntawm qhov siab.
Cov molar loj yog 183.18 g / mol. Saccharin tshwm li dawb crystalline khoom. Feem ntau, saccharin yog cov khoom siv hluav taws xob ruaj khov. Tsis tas li ntawd, nws tsis hnov mob nrog lwm cov khoom xyaw hauv cov khoom noj, thiab zoo sib xws, nws khaws cia zoo. Feem ntau, peb tuaj yeem siv cov khoom sib xyaw ntawm saccharin nrog rau lwm cov khoom qab zib txhawm rau txhawm rau them nyiaj rau qhov tsis muaj zog thiab ua txhaum ntawm lwm cov khoom qab zib.
Peb tuaj yeem tsim cov saccharin hauv ntau txoj hauv kev, suav nrog Remsen thiab Fahlberg txoj kev uas pib nrog toluene. Nyob rau hauv txoj kev no, sulfonation ntawm toluene yog ua tiav siv chlorosulfonic acid, uas muab cov ortho thiab para-hloov sulfonyl chloride. Tom qab ntawd, daim ntawv ortho yuav tsum tau muab cais tawm ntawm qhov sib tov, thiab tom qab ntawd nws hloov mus rau sulfonamide siv ammonia. Thaum kawg, oxidation ntawm cov tshuaj methyl hloov mus rau carboxylic acid, thiab nws ua rau cyclization, uas ua rau saccharin-dawb acid.
Qhov txawv ntawm Aspartame thiab Saccharin yog dab tsi?
Ob qho aspartame thiab saccharin yog cov khoom qab zib. Qhov sib txawv tseem ceeb ntawm aspartame thiab saccharin yog tias aspartame yog 200 npaug qab zib dua li saccharin. Ntxiv mus, aspartame yog ib qho tsis-saccharide, thaum saccharin yog hom saccharide. Tsis tas li ntawd, aspartame muaj calorie ntau ntau, yog li nws suav hais tias yog cov khoom qab zib qab zib, thaum saccharin yog cov khoom qab zib uas tsis yog calorie, yog li nws tsis muaj zaub mov tsawg.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm aspartame thiab saccharin hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Aspartame vs Saccharin
Aspartame yog ib qho organic compound uas muaj cov tshuaj formula C
14H18N2O5. Saccharin muaj cov tshuaj formula C7H5NO3S. Qhov sib txawv tseem ceeb ntawm aspartame thiab saccharin yog tias aspartame yog 200 npaug qab zib dua li saccharin.
