Stevia glycosides, tseem hu ua stevia extracts los yog stevia sweeteners, yog ib tug series ntawm high-siv sweeteners ib txwm muaj nyob rau hauv nplooj ntawm Stevia rebaudiana Bertoni. Nws qhov qab zib yog li ntawm 200-300 npaug ntawm sucrose (qab zib).
Nws muaj qhov zoo ntawm xoom calories, tsis muaj ntshav qab zib nce siab (glycemic Performance index 0), thiab muab rho tawm los ntawm cov nroj tsuag ntuj, thiab siv dav hauv cov khoom noj tsis muaj qab zib, tsis muaj calorie tsawg thiab dej haus. European zaub mov additive code yog E960.
Hom ntawmStevia Glycosides
Stevioside thiab Stevioside A yog cov khoom qab zib tseem ceeb, thaum lwm cov khoom muaj nyob hauv me me hauv Stevia nplooj. Cov steviol glycosides yog glycosides ntawm steviol cawv, nrog cov qauv molecular sib txawv tab sis txhua tus muaj tib lub cev pob txha, uas yog steviol cawv.
Qhov sib txawv ntawm lawv yog nyob rau hauv hom thiab qhov ntau ntawm cov piam thaj moieties khi los ntawm glycosidic bonds hauv C-13 thiab C-19, uas txiav txim siab lawv tus kheej cov qauv tshuaj thiab saj.
Nws zoo nkaus li tias ntau cov piam thaj hauv steviol glycosides, qhov zoo dua qhov qab zib thiab tsawg iab. Stevioside muaj peb cov piam thaj moieties, thaum rebaudin A muaj plaub thiab rebaudin M muaj rau cov piam thaj moieties. Ntawm peb, rebaudin M muaj qhov saj zoo tshaj plaws, ua raws li rebaudin A, thiab steviol glycoside dua.
Stevia nplooj muaj 6% -10% steviol glycosides, 2% -4%Rebaudioside A, thiab 1% -2% lwm yam me me steviol glycosides (Rebaudioside B, C, D, E, F, thiab M, steviol disaccharides, steviol glycosides, thiab dulcosin A).
Tam sim no, ntau tshaj 70 hom stevia glycosides tau tshawb pom, tab sis feem ntau ntawm lawv tsis muaj cov ntaub ntawv qab zib vim lawv cov ntsiab lus tsawg.
Cov ntsiab lus ntawm steviol glycosides suav txog li 60% -70% ntawm tag nrho cov steviol glycosides; Tom ntej no yog Rebaudioside A, uas suav txog li 15% txog 20% ntawm tag nrho cov ntsiab lus; Qhov thib peb yog Rebaudioside C, nrog rau cov ntsiab lus ntawm 5%.
Dab tsi yog qhov txawv ntawm Stevioside thiab Rebaudioside A?
Stevioside thiab rebaudioside A yog ob lub ntuj sweeteners nyob rau hauv nplooj ntawm cov nroj tsuag stevia. Lawv muaj tib yam qauv steviol tab sis tom kawg muaj ib qho ntxiv qabzib moiety, uas ua rau lawv qhov sib txawv.
Cov hauv qab no yog ob lub ntsiab sib piv:
Dej solubility: rebaudioside A yog ntau soluble hauv dej, nrog rau solubility 1%.
Qab zib saj thiab siv: reb A yog qab zib dua li stevioside, tsis muaj iab iab, thiab siv dav dua stevioside. Reb A tau suav tias yog qhov zoo tshaj plaws saj stevia, tab sis tom qab ntawd tuaj rebaudioside M (reb M).
Dab tsi yog Kev Siv Stevioside?
Stevioside tau raug cais tawm thawj zaug thiab siv rau hauv cov suab thaj qis / dawb thiab txo cov calories noj & haus ntawm lwm cov steviol glycosides. Nrog cov txiaj ntsig ntawm cov nroj tsuag ntuj tsim, xoom calorie, tsis nce ntshav qab zib (zoo rau cov ntshav qab zib).
Nrog rau qhov tseem ceeb ntawm kev txo qis calorie kom tsawg thiab noj qab zib, thiab nyiam cov khoom qab zib zoo nkauj, qee cov zaub mov thiab dej haus cov tuam txhab hloov pauv los ntawm kev siv cov khoom qab zib rau stevia sweeteners thiab cov txiv hmab txiv ntoo sweeteners.
Thaum siv los ua cov piam thaj hloov, tsuas yog ib qho me me ntawm stevioside yog xav tau kom ua tiav cov hom phiaj qab zib uas xav tau vim nws txog 250-300 npaug qab zib dua li cov suab thaj.
Txawm li cas los xij, nws txoj kev siv tsis dav li reb A vim nws qhov tsis zoo.
Kev siv khoom noj & dej haus
Steviol glycosidesyog cov khoom qab zib uas tsis yog khoom noj khoom haus uas tuaj yeem siv los ua lwm txoj hauv kev rau cov khoom qab zib (xws li aspartame, acesulfame k, sucralose, saccharin, neotame), thiab nrog cov khoom ntawm 200 mus rau 300 npaug ntau dua qab zib, xoom calorie, xoom glycemic Performance index, tsis. ua rau cov hniav lwj, tsis nce ntshav qab zib thiab tsim nyog rau cov neeg mob ntshav qab zib, nws yog qhov tsim nyog los tsim cov khoom noj uas tsis muaj suab thaj.
Steviol glycosides tau siv dav hauv cov khoom noj xws li carbonated dej qab zib, khoom noj siv mis, tshuaj yej, kua txiv, bakery, confectionery, pickles, khoom qab zib, thiab lwm yam. Lawv feem ntau ua ke nrog cov khoom qab zib.
