o, kev ntxhib los mos, caramel tsw, browning, ruaj khov, thiab lwm yam kev ua haujlwm ntawm qab zib yog txhua yam tseem ceeb hauv cov khoom noj thiab dej haus. Cov neeg tsim khoom lag luam yuav tsum xav txog thiab sib npaug ntawm qhov tsw thiab kev noj qab haus huv ntawm cov khoom txhawm rau txhawm rau nrhiav pom cov tshuaj hypoglycemic zoo. Cov yam ntxwv ntawm lub cev thiab lub cev ntawm cov piam thaj sib txawv hloov lawv txoj kev siv hauv cov khoom sib txawv rau cov tuam txhab raw khoom. Niaj hnub no, cov ntsiab lus xws li {{0}}} sucrose, 0 calories, thiab 0 calories tau nkag mus rau cov neeg siv khoom noj qab haus huv, uas ua rau muaj kev sib koom ua ke loj ntawm cov khoom qab zib tsawg. Nws yog ib qho tseem ceeb kom nkag siab txog yuav ua li cas khaws cia ntev kev lag luam kev sib tw thiab cov khoom tseem ceeb. Cov khoom siv ntawm cov khoom siv raw Nyob rau sab qauv, kev sib tw sib txawv yog qhov pib muaj zog. Puas yog steviol glycosides muaj kev nyab xeeb? Kab lus no yuav muab rau cov neeg siv qhov tob saib ntawm lubSteviol glycosides khoom.
Cov tshuaj glycoside tsim los ntawm Stevia nplooj cog yog hu ua steviol glycosides. Nws muaj qab zib thiab cov ntsiab lus calorie tsawg; nws qab zib yog 200-300 npaug ntawm sucrose, thiab nws cov calorie ntsiab lus tsuas yog 1/300 ntawm sucrose. Steviol glycosides tuaj hauv ntau hom, suav nrog Stevioside thiab Rebaudioside.
Stevia, ntawm qhov tod tes, muaj me ntsis tom qab saj, yog li nws feem ntau yog siv nrog lwm yam qab zib. Xwb, cais RebaudiosideA (RA95, RA80, RA50), uas muaj qab zib thiab tsis qab iab tsw thiab siv tau los hloov 15 mus rau 25 feem pua ntawm cov suab thaj hauv dej haus. Rebaudioside kuj tseem muaj RebB, RebC, RebD, RebE, thiab RebM ntxiv rau RebA. Reb M thiab Reb D muaj cov ntsiab lus tsawg heev ntawm Reb M thiab Reb D nyob rau hauv nplooj, tab sis lawv muaj qab zib zoo dua, tsis muaj iab, thiab saj uas yog ze rau sucrose.
Steviol glycosides kuj yog thermally ruaj khov, nrog rau qhov kub txog li 200 degree thaum lub sij hawm ci. Steviol glycosides tsis yog fermented los yog browned thaum lub sij hawm ci txheej txheem, cia cov khoom qab zib yuav khaws cia, tshav kub yuav tsum tau txo, txee lub neej yuav tsum tau ncua, thiab lub ci daim ntawv thov cheeb tsam yuav tsum tau nthuav. Txawm li cas los xij, nws yuav tsum tau ua ke nrog lwm cov piam thaj hloov, xws li erythritol thiab Luo Han Guo, vim muaj teeb meem xws li nqi thiab tsw.
Cov kev cai thiab kev siv ntawm steviol glycosides uas cuam tshuam
Steviol glycosides feem ntau yog siv nyob rau hauv Tuam Tshoj txoj kev lag luam ci, tshwj xeeb hauv ncuav mog qab zib, biscuits, thiab khoom qab zib. Lub National Health Commission ntawm Tuam Tshoj tau pom zoo glucosyl steviol glycoside raws li cov khoom noj khoom haus ntxiv rau xyoo 2016. Nws tuaj yeem siv los tsim cov khoom noj khoom haus rau ntau yam khoom noj, thiab qhov ntau npaum li cas yuav tsum tau kho raws li kev tsim khoom. Cov khoom siv raw yog glucosyl steviol glycosides tau los ntawm enzymatically glucosylation steviol glycosides muab rho tawm los ntawm nplooj stevia, tom qab ntawd evaporating, tsom, thiab tshuaj tsuag kom qhuav.
