Erythritol, ib lub ncuav qab zib, yog tetracarbonol nrog cov mis molecular ntawm C4H10O4. Erythritol yog dav pom nyob rau hauv cov xwm, xws li fungus nceb, lichens, melon thiab txiv hmab txiv ntoo melons, txiv hmab txiv ntoo, pears, thiab ib tug me me npaum li cas ntawm nws kuj yuav ntes tau nyob rau hauv lub qhov muag lens, plasma, fetal kua, phev thiab zis ntawm cov tsiaj. Nws tseem muaj nyob rau hauv ib qho me me hauv cov khoom noj fermented cawv, npias, kua ntses, thiab Japanese sake. Nws yog dawb crystalline hmoov uas tuaj yeem fermented los ntawm qabzib. Nws muaj lub qab zib qab zib, tsis yooj yim rau nqus, ruaj khov ntawm qhov kub thiab txias, ruaj khov nyob rau hauv ntau yam pH, thiab muaj qhov txias txias thaum yaj hauv qhov ncauj. Nws yog haum rau ntau yam khoom noj.
Cov yam ntxwv ntawm erythritol:
1. Tsis tshua muaj qab zib: Erythritol tsuas yog 60 feem pua - 70 feem pua sweeter dua sucrose. Nws muaj ib tug txias saj nyob rau hauv lub qhov ncauj, muaj ib tug ntshiab saj, thiab tsis muaj aftertaste. Nws tuaj yeem siv ua ke nrog lub zog muaj zog sweetener los tiv thaiv qhov tsis zoo ntawm nws lub zog sweetener.
2. Kev ruaj ntseg siab: nws ruaj khov rau cov kua qaub thiab kub, thiab muaj kev tiv thaiv siab rau cov kua qaub thiab alkali. Nws yuav tsis decompose thiab hloov hauv qab 200 degree, thiab yuav tsis hloov xim vim Maillard cov tshuaj tiv thaiv.
3. Kev kub siab ntawm kev sib cais: Erythritol muaj cov nyhuv tshav kub thaum yaj hauv dej. Lub tshav kub ntawm kev sib cais tsuas yog 97.4kJ / kg, uas yog siab dua li cov piam thaj thiab sorbitol. Nws muaj qhov txias txias thaum noj.
4. Solubility: Lub solubility ntawm erythritol ntawm 25 degree yog 37 feem pua (W/W). Nrog rau qhov kub thiab txias, solubility ntawm erythritol nce, thiab nws tsis yooj yim rau crystallize thiab precipitate crystals.
5. Tsawg hygroscopicity: Erythritol yog ib qho yooj yim heev rau crystallize, tab sis nws yuav tsis nqus noo noo nyob rau hauv 90 feem pua ntawm cov av noo ib puag ncig. Nws yog ib qho yooj yim rau crush kom tau cov khoom siv hmoov, uas tuaj yeem siv rau saum npoo ntawm cov khoom noj kom tsis txhob muaj cov khoom noj los ntawm kev nqus dej noo thiab deterioration.
Cov txiaj ntsig ntawm erythritol:
1. Antioxidation: Erythritol yog ib qho muaj zog antioxidant, uas tuaj yeem tshem tawm cov dawb radicals hauv lub cev thiab tiv thaiv cov dawb radicals txuas ntxiv mus ua phem rau lub cev. Qhov no pab tiv thaiv cov hlab ntsha puas tsuaj los ntawm hyperglycemia, kuj tseem muaj txiaj ntsig zoo rau cov tawv nqaij noj qab haus huv, thiab tuaj yeem ncua kev laus.
2. Ua kom cov khoom qab zib: Erythritol yog cov khoom qab zib, uas tsis muaj calorie ntau ntau. Ntxiv rau cov zaub mov tuaj yeem ua rau nws qab zib, tab sis nws yuav tsis cuam tshuam rau qib ntawm insulin lossis ntshav qab zib. Erythritol yog cov khoom qab zib nrog qab zib ntawm 60 feem pua - 70 feem pua ntawm sucrose. Nws muaj qhov qab zib qab zib hauv lub qhov ncauj thiab feem ntau siv hauv cov ncuav, khoom qab zib, dej haus thiab lwm yam khoom noj.
3. Kev tiv thaiv qhov ncauj: Erythritol muaj calories tsawg, txog 6 feem pua. Thiab cov molecule yog me me, yooj yim rau absorbed thiab siv los ntawm tib neeg lub cev, thiab yuav tsis metabolized los ntawm enzymes. Nws muaj kev ruaj ntseg thiab kev ua siab ntev, thiab yuav tsis siv los ntawm cov kab mob hauv qhov ncauj, yog li nws yuav tsis ua rau cov hniav puas tsuaj, tab sis kuj txo qis kev loj hlob ntawm cov kab mob hauv qhov ncauj thiab tiv thaiv qhov ncauj kom zoo.
4. Pab kom poob phaus
Txawm hais tias erythritol yog qab zib, nws tsis muaj calories. Nws yog ib tug natural zero-calorie sweetener. Rau cov khoom qab zib, ntxiv erythritol tuaj yeem txo tsawg kawg 30 feem pua ntawm cov calories, thiab yuav tsis coj qhov tsis zoo tom qab siv. Tom qab noj mov, nws tuaj yeem pab kom poob phaus, thiab tsim nyog rau cov neeg uas xav kom poob phaus los hloov cov suab thaj.
5. Txhim kho tsw
Erythritol tuaj yeem txhawb kev sib xyaw ua ke ntawm ethanol molecules thiab dej molecules. Cov dej cawv muaj peev xwm txo tau cov ntxhiab tsw thiab hnov tsw ntawm cawv, thiab tuaj yeem txhim kho qhov zoo ntawm Baijiu thiab cawv. Nyob rau tib lub sijhawm, Erythritol tseem tuaj yeem txhim kho qhov tsis hnov tsw ntawm cov nroj tsuag, collagen, peptides thiab lwm yam tshuaj. Tam sim no, Erythritol tau ntxiv rau qee cov khoom tsim collagen los txhim kho saj.
Piv nrog xylitol, erythritol muaj qhov zoo hauv qab no:
1. Erythritol yog ib yam khoom qab zib uas tsis muaj calorie, thaum xylitol yog caloric.
2. Erythritol muaj siab ntev dua xylitol. Tag nrho cov qab zib cawv yuav ua rau raws plab yog tias noj ntau dhau. Muaj teeb meem kam rau ua, thiab erythritol yog qhov siab tshaj plaws ntawm tib neeg lub cev.
3. Qhov nruab nrab cov piam thaj hauv cov ntshav thiab qhov nruab nrab insulin Performance index ntawm erythritol yog qis dua li ntawm xylitol. Yog li, erythritol tsis tshua muaj txiaj ntsig rau cov ntshav qabzib thiab muaj cov haujlwm antioxidant.
4. Ntau lub suab qab zib yuav hnov tsw txias thaum noj. Qhov kev xav txias no los ntawm kev nqus cua sov los ntawm kev tawg. Thaum yaj, nws yuav nqus koj cov cua sov, yog li peb xav tias txias. Lub degree ntawm coolness ntawm txhua yam khoom yog qhia los ntawm coefficient ntawm tshav kub ntawm dissolution thiab nqus. Erythritol muaj qhov kub siab tshaj plaws ntawm kev sib cais thiab kev nqus, thiab nws qhov txias yog qhov siab tshaj plaws.
5. Nyob rau hauv cov nqe lus ntawm cov txheej txheem ntau lawm, erythritol yog cov suab thaj nkaus xwb uas tsim los ntawm fermentation, uas yog ze rau natural transformation thiab extraction. Lwm cov piam thaj cawv yog tsim los ntawm hydrogenation, yog li cov txheej txheem ntau lawm txawv.
6. Erythritol yog ib txwm tsis-hygroscopic, thiab lwm yam qab zib cawv muaj ntau qib ntawm hygroscopicity, yog li tsis-hygroscopicity nce daim ntawv thov teb.
7. Xylitol feem ntau yog siv hauv cov khoom qab zib thiab tshuaj hauv Tebchaws Europe. Txawm hais tias xylitol tau ntxiv rau hauv qhov tsim nyog raws li FDA thiab European cov cai, kev noj xylitol ntau dhau yuav ua rau cov tsos mob xws li ntshav qab zib thiab raws plab.
