meso-Erythritol (CAS: 149-32-6) yog ib qho khoom xyaw ntuj ntawm ntau yam khoom noj thiab dej haus hauv qib qee zaum tshaj 1 g / kg.Nyob ntawm seb qhov concentration siv, erythritol yog kwv yees li 60% qab zib li sucrose.Nws yog noncariogenic thiab tsis metabolized hauv tib neeg lub cev uas txhais tau hais tias nws tsis muaj calorie ntau ntau.Hauv European Union, erythritol tau pom zoo raws li E 968 rau ntau daim ntawv thov zaub mov.Nws yog GRAS hauv Tebchaws Meskas thiab tau pom zoo hauv ntau lub tebchaws.
Meso-Erythritol yog ib qho qab zib cawv (polyol).Qhov qab zib ntawm erythritol yog qhov tsawg, qhov qab zib ntawm erythritol tsuas yog 60% -70% ntawm sucrose, qhov nkag tau txias saj, saj yog ntshiab, thiab tsis muaj qab zib iab.Nws tuaj yeem siv ua ke nrog cov khoom qab zib siab siv los tiv thaiv nws qhov tsis xav tau ntawm cov khoom qab zib siab.Erythritol muaj kev ruaj ntseg, ruaj khov rau cov kua qaub thiab kub, thiab muaj kua qaub thiab alkali tsis kam.Nws yuav tsis decompose thiab hloov ntawm kub hauv qab 200 ℃, thiab yuav tsis undergo Maillard cov tshuaj tiv thaiv ua rau discoloration.Lub tshav kub ntawm kev sib cais ntawm erythritol yog siab: erythritol muaj cov nyhuv endothermic thaum yaj hauv dej, thiab qhov kub ntawm kev sib cais tsuas yog 97.4kJ / kg, uas siab tshaj qhov endothermic degree ntawm qabzib thiab sorbitol, thiab muaj qhov txias txias thaum noj mov. .Solubility ntawm erythritol ntawm 25 ℃ yog 37% (W / W).Nrog rau qhov kub thiab txias, solubility ntawm erythritol nce, thiab nws yooj yim rau crystallize thiab cais tawm cov muaju.Erythritol yog ib qho yooj yim rau crystallize, tab sis nws yuav tsis nqus noo noo nyob rau hauv 90% humidity ib puag ncig.Nws yog ib qho yooj yim uas yuav tau crushed kom tau ib tug hmoov khoom, uas yuav siv tau rau saum npoo ntawm cov khoom noj kom tsis txhob muaj cov khoom noj los ntawm absorbing noo noo thiab deteriorating.
meso-Erythritol, nyob rau hauv chav kawm ntawm cov piam thaj cawv, tau txheeb xyuas ntau yam khoom noj, txiv hmab txiv ntoo, zaub, dej haus thiab khoom noj khoom haus.Nws yog lub npe hu ua cov khoom noj uas tsis muaj glycemic ntxiv thiab ua lub luag haujlwm tseem ceeb ua cov khoom qab zib rau cov neeg mob ntshav qab zib, vim nws tsis muaj glycemic lossis insulinemic effect vim nws muaj peev xwm tsis tau metabolized tab sis tau nqus hauv cov hnyuv.Nws kuj tau tshaj tawm tias siv los ua cov piam thaj hloov hauv cov tshuaj txhuam hniav, zom cov pos hniav, khoom noj khoom haus, thiab lwm yam.
Daim ntawv thov teb
1. Dej Haus Hauv xyoo tsis ntev los no, erythritol tau siv rau hauv kev tsim cov dej haus uas tsis muaj calories thiab tsawg-calorie.Erythritol tuaj yeem ua rau kom qab zib, lub cev thiab smoothness ntawm cov dej qab zib, thaum txo iab, thiab tseem tuaj yeem npog lwm yam tsw thiab txhim kho cov dej qab zib.Erythritol kuj tseem siv tau rau hauv cov dej qab zib, vim erythritol absorbs cua sov ntau thaum nws yaj.
2. Cov khoom ci
Erythritol yog cov khoom pov thawj rau kev ua haujlwm zoo dua lossis cov khoom noj uas muaj calorie tsawg.Nws tuaj yeem tsis tsuas yog hloov sucrose lub cev thiab tshuaj lom neeg xwb tab sis kuj coj cov txiaj ntsig kev noj qab haus huv, thiab cov khoom ci uas siv erythritol muaj cov qauv zoo dua qub thiab softness dua li cov khoom uas kuj siv sucrose ua raw cov ntaub ntawv, Thiab nws muaj ntau yaj-hauv-lub-qhov ncauj thiab xim hloov maj mam. sib txawv.Lub erythritol siv rau hauv cov khoom ci yuav tsum zoo dua yog hmoov lossis crystallized nrog ib qho me me me me (<200μm), thiab cov khoom zoo yuav ua rau cov khoom zoo sib xws.
3. Cov tshuaj ntxiv
Erythritol kuj tseem siv tau los tsim cov khoom noj khoom haus zoo ntxiv xws li jams, qab zib, butter icing thiab qee qhov chaw dai kom zoo nkauj.
A. Ntxiv erythritol rau jam tuaj yeem txhim kho lub ntuj fruity Performance index.
B. Ntxiv erythritol rau cream icing (tag nrho cov rog) yuav tsis tsuas txo calories tab sis kuj coj ib tug refreshing saj;Thaum cov khoom siv erythritol, maltitol kua thiab aspartame tib lub sijhawm, tus nqi zog yuav raug txo los ntawm ze li 50%.
4. Khoom qab zib
Kev lag luam khoom qab zib thiab chocolate tam sim no kuj tau txuas ntxiv los ntawm kev siv sucrose thaum ntxov ua cov khoom siv raw rau cov khoom qab zib tshiab thiab cov khoom qab zib tsawg-calorie.Nyob rau hauv xyoo tas los no, cov khoom qab zib ua haujlwm tau raug hyped nyob rau hauv tag nrho viav vias hauv kev ua lag luam thiab tau dhau los ua lub ntiaj teb tam sim no Kev noj haus hotspot thiab kev loj hlob tsom ntawm cov khoom qab zib ua lag luam, kev lag luam muaj peev xwm loj.Tom qab kev tshawb fawb siv tau ntev, nws tau raug pov thawj tias cov khoom siv raw khoom tshiab erythritol ua tau raws li qhov yuav tsum tau ua.Cov saj ntawm erythritol yog tib yam li sucrose, thiab tsis tas yuav ntxiv cov khoom qab zib zoo li aspartame lossis saccharin.Cov khoom qab zib uas tau tshwm sim yog txias dua thiab txias dua li lwm cov khoom qab zib "tsis yog sucrose", nrog cov qab zib ntshiab thiab tsis muaj qab ntxiag tom qab.
5. Chocolate
Erythritol tuaj yeem hloov tau yooj yim sucrose hauv cov khoom thiab txo lub zog ntawm chocolate los ntawm 34%.Tsis muaj lwm yam qab zib cawv tuaj yeem muab qhov txo qis zog, thiab muab cov khoom lag luam nrog lub saj txias thiab cov khoom tsis muaj cariogenic.Vim nws tsis tshua muaj hygroscopicity, erythritol pab kov yeej qhov tshwm sim tawg ntawm lwm cov suab thaj thaum ua chocolate.
6. Kev lag luam kws tshuaj
Cov khoom ntawm erythritol, xws li tshuaj tiv thaiv kab mob, tiv thaiv oxidation, noo noo tuav thiab tsis-flammable, ua rau nws daim ntawv thov nyob rau hauv cov tshuaj thiab cov tshuaj niaj hnub txuas ntxiv mus.
meso-Erythritol yog ib qho tshwm sim tsis muaj carriogenic excipient siv nyob rau hauv ntau yam tshuaj npaj, suav nrog hauv cov ntaub ntawv ntau npaum li cov ntsiav tshuaj muab tub lim, thiab hauv txheej txheej.Nws kuj tau raug tshawb xyuas los siv rau hauv cov hmoov qhuav qhuav.Nws kuj tseem siv rau hauv cov tshuaj tsis muaj piam thaj, thiab tshuaj zom cov pos hniav.meso-Erythritol kuj tseem siv tau los ua ib qho diluent hauv ntub granulation ua ke nrog cov tshuaj noo-rhiab heev.Nyob rau hauv daim ntawv thov buccal, xws li tshuaj noj cov pos hniav, nws yog siv vim nws siab tsis zoo cua sov ntawm cov tshuaj uas muab ib tug muaj zog txias nyhuv.meso-Erythritol kuj tseem siv los ua cov khoom qab zib uas tsis muaj calorie hauv cov kua qab zib;nws yog siv los muab cov khoom siv hluav taws xob hloov kho nrog cov khoom qab zib hnyav;thiab nws kuj yog siv los npog qhov tsis xav tau tom qab.meso-Erythritol kuj tseem siv los ua cov khoom qab zib uas tsis muaj cariogenic hauv cov tshuaj txhuam hniav thiab tshuaj ntxuav qhov ncauj.
DEFINITION
Erythritol yog tau los ntawm fermentation ntawm starch enzyme hydrolyzate (los ntawm starches xws li nplej thiab pob kws).Nws yog tau los ntawm fermentation broth ntawm haum osmophilic poov xab xws li Moniliella pollinis los yog Trichosporonoides megachiliensis.Nws muaj NLT 96.0% thiab NMT 102.0% ntawm Erythritol (C4H10O4), xam raws li anhydrous hauv paus.
