Qhov txawv ntawm sucrose thiab sucralose yog tias sucrose molecule muaj peb pawg hydroxyl, hos sucralose molecule muaj peb chlorine atoms.
Qhov txawv ntawm cov qauv tshuaj ntawm sucrose thiab sucralose muab lawv cov tshuaj sib txawv thiab lub cev. Txawm li cas los xij, ob lub tebchaw no muaj txiaj ntsig zoo li sweeteners. Sucralose yog cov khoom siv hluavtaws uas qab zib dua sucrose. Tsis zoo li sucrose, cov tshuaj no muaj pes tsawg pab rau calories hauv peb cov zaub mov.
Sucrose yog dab tsi?
Sucrose yog disaccharide uas muaj cov piam thaj thiab fructose qab zib molecules. Nws yog qhov peb feem ntau hu ua qab zib. Nroj tsuag tuaj yeem tsim qhov sib xyaw no ib txwm muaj. Yog li ntawd, peb tuaj yeem kho qhov sib xyaw no los ntawm cov nroj tsuag. Cov tshuaj formula ntawm no compound yog C12H22O11. Nws molar mass yog 342.3 g / mol. Txawm li cas los xij, nws muaj qhov ntsuas glycemic qis, yog li nws tsis tuaj yeem nce ntshav qab zib tam sim ntawd. Yog li, nws muaj qhov cuam tshuam tsawg kawg ntawm cov ntshav qabzib.
Daim duab 01: Cov Qauv Tshuaj ntawm Sucrose Molecule
Peb tuaj yeem rho tawm thiab ua kom zoo dua sucrose los ntawm qab zib pas nrig lossis qab zib beet rau tib neeg noj. Peb tuaj yeem ua qhov no hauv cov khoom qab zib. Nyob rau hauv lub zeb no, cov suab thaj yog crushed kom tau cov suab thaj nyoos. Cov qab zib nyoos no yog tom qab ntawd ua kom zoo kom tau cov sucrose ntshiab. Nyob rau hauv cov txheej txheem no, peb ntxuav cov hmoov qab zib nyoos, yaj lawv mus rau hauv ib lub qab zib phoov, lim thiab hla cov pa roj carbon monoxide kom tshem tawm cov xim seem. Cov sucrose no feem ntau siv hauv kev tsim khoom noj thiab hauv ntau cov zaub mov txawv thiab.
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 Molecule
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 mus rau cov hmoov dawb; nws yog odorless thiab. Sucralose tuaj yeem piav qhia tias yog ib qho disaccharide compound uas yog tsim los ntawm kev xaiv chlorination ntawm sucrose nyob rau hauv ib txoj kev multistep, qhov twg peb cov hydroxyl pawg tau hloov nrog chlorine atoms. Thaum kawg, kev tiv thaiv los ntawm hydrolysis ntawm ester yog ua kom tau cov sucralose.
Qhov txawv ntawm Sucrose thiab Sucralose yog dab tsi?
Sucrose yog disaccharide uas muaj cov piam thaj thiab fructose qab zib molecules. Sucralose yog ib qho khoom qab zib uas muaj txiaj ntsig zoo li kev hloov qab zib. Qhov sib txawv tseem ceeb ntawm sucrose thiab sucralose yog tias sucrose molecule muaj peb pawg hydroxyl, thaum lub sucralose molecule muaj peb chlorine atoms, uas hloov peb pawg hydroxyl hauv sucrose molecule. Ntxiv mus, sucrose tsis qab zib dua li sucralose; Qhov tseeb, sucralose yog li 400-800 npaug qab zib dua sucrose. Tsis tas li ntawd, sucrose muaj 16 calories ib teaspoon thaum sucralose muaj pes tsawg pab rau calories.
Cov infographic hauv qab no nthuav tawm qhov sib txawv ntawm sucrose thiab sucralose hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Sucrose vs Sucralose
Sucrose yog disaccharide uas muaj cov piam thaj thiab fructose qab zib molecules. Sucralose yog ib qho khoom qab zib uas muaj txiaj ntsig zoo li kev hloov qab zib. Qhov sib txawv tseem ceeb ntawm sucrose thiab sucralose yog tias cov molecule sucrose muaj peb pawg hydroxyl, thaum sucralose molecule muaj peb chlorine atoms, uas hloov peb pawg hydroxyl hauv sucrose molecule. Tsis tas li ntawd, sucralose yog cov khoom siv hluavtaws uas qab zib heev dua sucrose, thiab tsis zoo li sucrose, cov khoom no tsis muaj txiaj ntsig rau calories hauv peb cov zaub mov.
