Kev noj qab haus huv sweetener txhais tau hais tias thaum qee cov khoom qab zib muaj qhov qab zib zoo ib yam li sucrose, nws cov nqi calorific yog ntau tshaj 2% ntawm tus nqi caloric ntawm sucrose. Cov khoom qab zib uas tsis yog khoom noj khoom haus tau txhais tau tias muaj tus nqi calorific qis dua 2% ntawm tus nqi caloric ntawm sucrose.
Natural non-nutritive sweeteners tau txais kev saib xyuas ntxiv thiab yog txoj kev loj hlob ntawm cov khoom qab zib. WHO tau taw qhia tias ntau dua 50 lab tus neeg mob ntshav qab zib tau mus txog ntau dua li ib feem peb ntawm cov neeg Asmeskas uas xav tau cov zaub mov tsis muaj calorie. Ntawm cov kev hloov pauv sucrose, aspartame feem ntau yog siv hauv Tebchaws Meskas, uas suav txog ntau dua 90%, thaum Nyij Pooj tau tswj hwm los ntawm steviol glycosides, thiab cov neeg European xav paub ntau dua AK qab zib (acesulfame K). Peb cov khoom qab zib uas tsis yog khoom noj khoom haus no tuaj yeem siv hauv Suav teb.
Los ntawm kev xav ntawm kev lag luam xav tau thiab kev tshawb fawb ntawm cov khoom qab zib, txoj kev loj hlob ntawm sweeteners feem ntau muaj ob yam: [7]
High qab zib sweetener
Cov khoom qab zib qab zib muaj qhov zoo ntawm cov qab zib siab, calories tsawg, caries tsawg, kev nyab xeeb siab, thiab lwm yam, thiab feem ntau ntawm cov khoom qab zib no yog cov khoom qab zib tsis muaj qab zib, uas tsis tswj los ntawm insulin thaum lub sij hawm metabolic thiab yuav tsis ua rau rog rog. ntshav siab nce, haum rau cov neeg mob ntshav qab zib thiab rog rog raws li kev hloov qab zib.
Functional sweetener
Functional sweeteners (feem ntau yog oligosaccharides nyob rau theem no) tsis tsuas yog muaj cov yam ntxwv ntawm cov calories tsawg, kev ruaj ntseg siab, kev nyab xeeb thiab tsis muaj tshuaj lom, tab sis kuj tseem muaj lub luag haujlwm tshwj xeeb ntawm kev txhawb nqa kev tsim tawm ntawm probiotics thiab inhibiting kev loj hlob ntawm cov kab mob phem. Lub physiological kev ua haujlwm ntawm kev ua haujlwm oligosaccharides tam sim no tau lees paub feem ntau suav nrog cov hauv qab no:
1. Nws tsis yooj yim rau kev nqus los ntawm tib neeg lub cev, thiab muab cov calories tsawg lossis tsis muaj calories, thiab tuaj yeem siv rau cov neeg mob ntshav qab zib, cov neeg rog rog thiab cov neeg mob hyperglycemia.
2. Ua kom cov kab mob bifidobacteria hauv cov hnyuv thiab txhawb lawv txoj kev loj hlob. Functional oligosaccharides yog qhov kev loj hlob ntawm cov kab mob muaj txiaj ntsig hauv txoj hnyuv, thiab lub hom phiaj nthuav dav tshaj plaws yog bifidobacteria. Tib neeg kev sim tau pom tias qee qhov kev ua haujlwm oligosaccharides, xws li isomalto-oligosaccharides, yog siv los ntawm bifidobacteria thiab qee cov kab mob lactic acid hauv cov hnyuv loj tom qab noj rau hauv tib neeg lub cev, thaum cov kab mob plab hnyuv Perfringens thiab Clostridium spoilage vim cov kab mob tsis tuaj yeem siv. Qhov chaw ntawm bifidobacteria muaj oligosaccharide receptors, thiab ntau oligosaccharides yog cov txiaj ntsig zoo bifidus.
3. Nws yuav tsis ua rau cov hniav lwj, uas yog qhov zoo rau kev tu lub qhov ncauj.
4. Nws muaj qee qhov kev ua haujlwm ntawm lub cev ntawm cov khoom noj fiber ntau, xws li txo cov roj cholesterol thiab tiv thaiv kab mob qog noj ntshav.
