Polydextrose yog ib hom tshiab ntawm dej-soluble dietary fiber. Txog tam sim no, nws tau pom zoo los ntawm ntau dua 50 lub teb chaws los siv los ua cov khoom noj muaj txiaj ntsig zoo. Nws yog dav siv hauv kev tsim cov khoom noj muaj zog fiber ntau. Tom qab noj mov, nws muaj txoj haujlwm ua kom cov hnyuv thiab plab tsis muaj kev cuam tshuam. Polydextrose tsis tsuas yog muaj lub luag haujlwm tshwj xeeb ntawm cov khoom noj tsis muaj fiber ntau, xws li ua kom cov quav ntim ntau ntxiv, txhim kho qhov quav thiab txo qhov kev pheej hmoo ntawm kev mob qog noj ntshav, tab sis kuj muaj cov haujlwm uas tsis muaj kev noj haus fiber ntau tsis muaj lossis tsis pom tseeb. Piv txwv li, ua ke nrog kev tshem tawm ntawm cholic acid hauv lub cev, polydextrose tuaj yeem txo cov roj cholesterol ntau, yooj yim dua ua rau satiety, thiab tuaj yeem txo cov ntshav qabzib ntau tom qab noj mov.

Specification ntawm polydextrose muaj nuj nqi
(1), tsis muaj cua sov
Polyglucose yog cov khoom ntawm random polymerization. Muaj ntau hom glycosidic bonds, complex molecular qauv thiab nyuaj biodegradation. [3]
Polydextrose tsis absorbed thaum dhau los ntawm lub plab thiab cov hnyuv. Kwv yees li 30% yog fermented los ntawm cov kab mob hauv cov hnyuv loj los tsim cov roj fatty acids thiab CO2. Kwv yees li 60% tawm ntawm cov quav, thiab cov cua sov tsim tawm tsuas yog 25% ntawm sucrose thiab 11% ntawm cov rog. Cov roj tsawg heev tuaj yeem hloov mus ua rog, uas tsis tuaj yeem ua rau kub taub hau.
(2) Kho lub plab zom mov thiab txhawb kev nqus ntawm cov as-ham
Txij li kev noj zaub mov muaj fiber ntau ua rau muaj qhov sib npaug ntawm lub plab zom mov, kev noj zaub mov muaj fiber ntau yog tus yuam sij rau kev noj qab haus huv ntawm lub plab zom mov.
Raws li cov dej-soluble dietary fiber, polydextrose tuaj yeem txo lub sijhawm tshem tawm ntawm cov zaub mov hauv lub plab, txhawb kev zais ntawm cov kua txiv hmab txiv ntoo, pab txhawb kev nqus thiab zom cov as-ham, txo lub sijhawm rau cov ntsiab lus (feem) kom dhau los ntawm txoj hnyuv, txo. Lub siab ntawm txoj hnyuv, txo lub sij hawm sib cuag ntawm cov khoom tsis zoo nyob rau hauv txoj hnyuv thiab lub plab hnyuv phab ntsa, txhawb txoj hnyuv txav thiab txhim kho osmotic siab ntawm txoj hnyuv, Yog li kom dilute cov concentration ntawm cov teeb meem tshuaj nyob rau hauv lub plab zom mov thiab txhawb lawv excretion. los ntawm lub cev.
Yog li, polydextrose tuaj yeem txhim kho txoj hnyuv ua haujlwm zoo, txhawb kev zom zaub mov, tshem tawm cem quav, tiv thaiv hemorrhoids, txo cov tshuaj lom thiab raws plab los ntawm cov khoom tsis zoo, txhim kho plab hnyuv thiab pab tiv thaiv qog noj ntshav.
(3). prebiotics tswj qhov sib npaug ntawm cov hnyuv
Polydextrose yog ib qho zoo prebiotic. Tom qab noj rau hauv tib neeg lub cev, nws tsis tau zom rau sab sauv ntawm txoj hnyuv, tab sis fermented nyob rau hauv qis qis ntawm txoj hnyuv, uas yog qhov tsim nyog rau kev tsim cov kab mob hauv plab hnyuv (Bifidobacterium thiab Lactobacillus) thiab inhibit tsim kev puas tsuaj. Cov kab mob xws li Clostridium thiab Bacteroides. Polydextrose yog fermented los ntawm cov kab mob uas muaj txiaj ntsig los tsim cov saw luv luv fatty acids xws li butyric acid, uas txo cov pH tus nqi ntawm txoj hnyuv, tuaj yeem pab tiv thaiv kab mob thiab txo kev pheej hmoo ntawm mob qog noj ntshav. Yog li, polydextrose tuaj yeem muab cov khoom noj khoom haus nrog cov khoom xyaw prebiotic zoo rau kev noj qab haus huv ntawm plab hnyuv.
(4) Txo cov ntshav qabzib
Polydextrose tuaj yeem txhim kho qhov rhiab heev ntawm ob peb cov ntaub so ntswg mus rau insulin, txo qhov kev xav tau ntawm cov tshuaj insulin, inhibit insulin secretion, cuam tshuam kev nqus cov suab thaj, thiab polydextrose nws tus kheej tsis nqus, yog li ua tiav lub hom phiaj ntawm kev txo cov ntshav qab zib, uas yog heev. haum rau cov ntshav qab zib. Polydextrose tsuas muaj 5 - 7 txheeb ze rau cov ntshav qabzib, thaum cov piam thaj muaj 100.
(5) Txhawb kev nqus ntawm cov ntxhia hauv cov ntsiab lus
Qhov sib ntxiv ntawm polydextrose hauv kev noj zaub mov tuaj yeem txhawb nqa kev nqus ntawm calcium hauv txoj hnyuv, uas tej zaum yuav yog vim polydextrose yog fermented nyob rau hauv txoj hnyuv los tsim cov saw luv fatty acids, uas acidifies lub plab hnyuv ib puag ncig, thiab acidified ib puag ncig tsub kom lub nqus ntawm calcium. Cov kev tshawb fawb luam tawm nyob rau hauv Phau Ntawv Qhia Txog Kev Noj Qab Haus Huv (2001) los ntawm xibfwb Hitoshi Mineo ntawm Nyij Pooj qhia tau hais tias calcium nqus ntawm jejunum, ileum, cecum thiab cov hnyuv loj ntawm cov nas nce nrog qhov nce ntawm polyglucose concentration hauv 0-100mmol / L.
