Qhov sib txawv tseem ceeb ntawm saccharin thiab sucralose yog tias saccharin tsis qab zib dua sucralose.
Ob qho tib si saccharin thiab sucralose muaj txiaj ntsig zoo li cov khoom qab zib. Peb tuaj yeem sib piv ob yam khoom no nrog lawv cov qauv tshuaj, cov khoom, thiab lawv cov qab zib. Feem ntau, saccharin tuaj yeem muab qhov qab zib uas yog li 300-400 sweeter dua qab zib, thaum sucralose tuaj yeem yog li 400-700 npaug sweeter dua qab zib.
Saccharin yog dab tsi?
Saccharin yog hom khoom qab zib uas tsis muaj zaub mov muaj zog. Cov tshuaj no yog hais txog 300-400 lub sij hawm sweeter dua sucrose. Txawm li cas los xij, nws muaj iab los yog xim hlau tom qab saj. Ib qho aftertaste yog hais txog qhov saj ntawm ib qho khoom noj uas peb yuav pom tam sim ntawd tom qab tshem tawm cov zaub mov ntawm lub qhov ncauj. Qhov no iab los yog xim hlau tom qab saj ntawm saccharin tuaj yeem saj feem ntau ntawm qhov siab.
Daim duab 01: Cov Qauv Tshuaj ntawm Saccharin
Cov tshuaj formula ntawm saccharin yog C7H5NO3S, thiab molar mass yog 183.18 g / mol. Nws zoo nkaus 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 methyl hloov mus rau carboxylic acid, thiab nws ua rau cyclization, uas ua rau saccharin dawb acid.
Sucralose yog dab tsi?
Sucralose yog ib qho khoom qab zib uas muaj txiaj ntsig zoo li kev hloov qab zib. Feem ntau, feem ntau ntawm kev noj sucralose tsis tawg hauv peb lub cev. Yog li ntawd, peb tuaj yeem muab nws lub npe hu ua noncaloric. Tus lej E rau cov khoom noj ntxiv no yog E 955. Tsis tas li ntawd, qhov hloov qab zib no suav tias yog txee ruaj khov thiab muaj kev nyab xeeb siv rau qhov kub siab.
Daim duab 02: Cov Qauv Tshuaj ntawm Sucralose
Cov tshuaj formula ntawm sucralose yog C12H19Cl3O8. Cov molar loj ntawm cov khoom no yog 397.64 g / mol. Nws zoo nkaus li ib qho tawm-dawb rau cov hmoov dawb thiab tsis muaj ntxhiab thiab. Sucralose tuaj yeem raug hu ua disaccharide compound uas yog tsim los ntawm kev xaiv chlorination ntawm sucrose nyob rau hauv ntau txoj hauv kev uas peb cov pab pawg hydroxyl raug hloov nrog chlorine atoms. Thaum kawg, kev tiv thaiv los ntawm hydrolysis ntawm ester yog ua kom tau cov sucralose.
Dab tsi yog qhov zoo sib xws ntawm Saccharin thiab Sucralose?
- Saccharin thiab sucralose yog khoom qab zib.
- Ob leeg qab qab heev.
- Cov no yog cov khoom tsis muaj calorie uas tsis tawg hauv peb lub cev.
Qhov txawv ntawm Saccharin thiab Sucralose yog dab tsi?
Saccharin yog hom khoom qab zib uas tsis muaj zaub mov muaj zog, qhov sucralose yog ib qho khoom qab zib uas muaj txiaj ntsig zoo li kev hloov qab zib. Qhov sib txawv tseem ceeb ntawm saccharin thiab sucralose yog tias saccharin tsis qab zib dua sucralose. Feem ntau, saccharin tuaj yeem muab qhov qab zib uas yog li 300-400 sweeter dua qab zib, thaum sucralose tuaj yeem yog li 400-700 npaug sweeter dua qab zib.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm saccharin thiab sucralose.
Summary – Saccharin vs Sucralose
Ob qho tib si saccharin thiab sucralose muaj txiaj ntsig zoo li cov khoom qab zib. Peb tuaj yeem sib piv ob yam khoom no nrog lawv cov qauv tshuaj, cov khoom, thiab lawv cov qab zib. Qhov sib txawv tseem ceeb ntawm saccharin thiab sucralose yog tias saccharin tsis qab zib dua sucralose.
