Qhov sib txawv tseem ceeb ntawm xylitol thiab erythritol yog xylitol muaj tsib carbon atoms thiab txhua cov pa roj carbon atom txuas rau ib pawg hydroxyl, hos erythritol muaj plaub carbon atoms, txhua carbon atom txuas nrog hydroxyl pawg.
Ob leeg xylitol thiab erythritol yog qab zib cawv. Cov tebchaw no tseem ceeb xws li cov piam thaj hloov pauv. Hloov cov piam thaj hauv cov zaub mov thiab tshuaj nrog xylitol lossis erythritol tuaj yeem txhawb nqa kev noj qab haus huv zoo dua thiab cov ntshav qab zib tsawg.
YXylitol yog dab tsi?
Xylitol yog cov tshuaj lom neeg muaj cov mis C2H12O5. Nws yog stereoisomer thiab tshwm sim raws li cov xim tsis muaj xim lossis dawb crystalline khoom uas yog dej-soluble. Peb tuaj yeem faib cov tshuaj no ua ib qho polyalcohol lossis qab zib cawv (ib qho alditol). Xylitol feem ntau yog siv los ua cov khoom noj ntxiv los hloov cov suab thaj hauv cov zaub mov thiab tshuaj. Yog li ntawd, peb tuaj yeem hu nws ua ib qho khoom qab zib.
Xylitol yog ib qho tshwm sim ntawm cov organic compounds (hauv me me) hauv plums, strawberry, cauliflower, taub dag, thiab lwm yam. Tsis tas li ntawd, tib neeg thiab ntau tus tsiaj kuj ua cov lej ntawm xylitol thaum lub sij hawm metabolism ntawm carbohydrates. Xylitol yog ib qho achiral compound. Qhov ntawd txhais tau tias, nws muaj lub dav hlau ntawm symmetry.
Daim duab 01: Xylitol
Kev tsim khoom lag luam ntawm xylitol pib nrog lignocellulosic biomass los ntawm xylan yog rho tawm. Cov khoom siv raw biomass tuaj yeem siv tau suav nrog cov ntoo tawv, cov ntoo mos, cov khib nyiab ua liaj ua teb los ntawm kev ua cov nplej, thiab lwm yam. Xylan yog cov khoom siv polymer uas peb tuaj yeem hydrolyze rau hauv xylose uas tom qab ntawd catalytically hydrogenated rau hauv xylitol. Hom kev hloov pauv no hloov cov piam thaj xylose rau hauv cov cawv thawj, xylitol.
Muaj ntau daim ntawv thov xylitol ua cov piam thaj hloov pauv. Cov khoom lag luam suav nrog tshuaj, tshuaj noj, khoom noj khoom haus, tshuaj txhuam hniav, zom cov pos hniav, thiab lwm yam. Tab sis nws tsis yog ib qho khoom qab zib hauv tsev. Qhov tseem ceeb tshaj, cov tshuaj no muaj qhov cuam tshuam tsis zoo rau cov ntshav qab zib vim xylitol ua rau cov metabolism hauv nws tus kheej ntawm insulin.
Erythritol yog dab tsi?
Erythritol yog cov organic compound uas muaj cov tshuaj formula C4H10O4. Nws yog qab zib cawv, thiab peb tuaj yeem siv nws ua zaub mov ntxiv thiab ua cov piam thaj hloov pauv. Cov tshuaj no yog ib yam khoom tshwm sim, thiab peb tuaj yeem ua los ntawm pob kws siv cov enzymes thiab fermentation. Nws yog stereoisomer.
Daim duab 02: Erythritol
Peb tuaj yeem lees paub erythritol 60-70% qab zib li sucrose. Txawm li cas los xij, nws yuav luag tsis muaj calorie. Yog li ntawd, nws tsis cuam tshuam rau cov ntshav qab zib los yog ua rau cov hniav lwj. Lawm, erythritol tshwm sim hauv qee cov txiv hmab txiv ntoo thiab cov khoom noj fermented. Industrially, peb tuaj yeem tsim nws los ntawm fermentation ntawm qabzib nrog poov xab.
Muaj ntau daim ntawv thov ntawm erythritol ua cov khoom noj ntxiv. Piv txwv muaj xws li dej haus xws li kas fes, tshuaj yej, tshuaj noj ua kua, kua txiv hmab txiv ntoo, dej qab zib, thiab dej tsw qab.
Thaum xav txog kev tsim cov erythritol, peb tuaj yeem tsim nws los ntawm cov hmoov txhuv nplej siab, pib nrog enzymatic hydrolysis ntawm cov hmoov txhuv nplej siab tau los ntawm pob kws los tsim cov piam thaj. Tom qab ntawd, cov piam thaj yog fermented nrog poov xab los yog lwm yam fungus los tsim erythritol.
Qhov txawv ntawm Xylitol thiab Erythritol yog dab tsi?
Ob leeg xylitol thiab erythritol yog qab zib cawv. Xylitol yog cov tshuaj sib xyaw uas muaj cov mis C2H12O5 thaum lub erythritol yog cov organic compound uas muaj cov tshuaj formula C4H10O4. Qhov sib txawv tseem ceeb ntawm xylitol thiab erythritol yog xylitol muaj tsib carbon atoms, whereas erythritol muaj plaub carbon atoms.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm xylitol thiab erythritol kom ntxaws.
Summary – Xylitol vs Erythritol
Xylitol thiab erythritol yog qab zib cawv uas tseem ceeb ua cov piam thaj hloov. Qhov sib txawv tseem ceeb ntawm xylitol thiab erythritol yog xylitol muaj tsib carbon atoms, txhua cov pa roj carbon atom txuas nrog hydroxyl pawg, thaum erythritol muaj plaub carbon atoms, txhua carbon atom txuas nrog hydroxyl pawg.
