Youdaoplaceholder0 1.1 Lub cev Khawv koob ntawm viscosity gradient: Triple transformation ntawm plab mus rau txoj hnyuv

Cov qauv molecular ntawm polyglucose yog tsim los ntawm randomly cross-linked qabzib residues, thiab qhov tshwj xeeb conformation endows nws nrog tshwj xeeb rheological zog. Nyob rau hauv ib puag ncig acidic ntawm lub plab (pH 1.5-3.5), nws cov molecular chains sai tsim cov qauv peb-dimensional network los ntawm hydrogen bonds, thiab cov viscosity tam sim ntawd nce mus rau 1200 mPa·s (kwv yees li ob npaug ntawm zib mu), zoo ncua lub plab zom mov kom txog li 40%. Tom qab nkag mus rau hauv cov hnyuv me, raws li tus nqi pH nce mus rau 6.0-7.5, qee cov hydrogen bonds tawg thiab cov viscosity poob mus rau 300-500 mPa·s. Nws tsis cuam tshuam rau kev nqus cov as-ham los yog ua ke nrog cov kua tsib acids kom txo tau qhov nqus ntawm cov cholesterol. Thaum mus txog rau txoj hnyuv, nyob rau hauv qhov kev txiav txim ntawm microbial fermentation, lub viscosity ntxiv txo mus rau hauv qab 50 mPa·s, tso cov luv-chain fatty acids (SCFAs) los muab lub zog rau cov probiotics (Daim duab 1).

Txoj cai viscosity ntawm polydextrose tsis tsuas yog cuam tshuam rau lub cev zom zaub mov, tab sis kuj tsim kev sib cuam tshuam nrog cov hnyuv. Lub xeev siab viscosity tsim ib qho kev thaiv lub cev nyob rau hauv txoj hnyuv loj, txo kev sib cuag ntawm cov kab mob pathogenic thiab plab hnyuv mucosa. Raws li cov viscosity txo qis, nws maj mam hloov mus rau hauv lub fermentable substrate, nyiam stimulating lub proliferation ntawm Bifidobacteria thiab lactic acid kab mob. Ib pab neeg los ntawm University of Cambridge tau tshawb pom los ntawm metagenomic sequencing uas tau noj tas li ntawm 12g / hnub ntawm polydextrose rau 8 lub lis piam tuaj yeem txhim kho F / B piv ntawm Thick-miliae / Bacteroidetes mus rau 1.3 (nrog rau lub hauv paus noj qab haus huv ntawm 1.5-2.0), thiab ua kom muaj cov kab mob ntau ntawm butuchric Faecali 8%. Qhov kev cuam tshuam ob theem ntawm "kev tiv thaiv ua ntej, tom qab noj zaub mov" zoo kawg nkaus ua tau raws li cov kev xav tau ntawm cov kab mob sib txawv ntawm cov hnyuv.

Youdaoplaceholder0 Conclusion: Redefining the "txawj ciam" ntawm Fiber

Lub viscosity gradient nyhuv ntawm polydextrose cim lub sijhawm tshiab rau kev noj haus fiber ntau, txav los ntawm "passive supplementation" mus rau "kev tswj hwm". Thaum cov khoom siv fiber ntau tuaj yeem tswj hwm nws tus kheej hauv kev teb rau qhov chaw digestive ib puag ncig, peb tuaj yeem pom qhov kev hloov pauv hauv kev noj zaub mov zoo - kev cuam tshuam kev noj qab haus huv yav tom ntej yuav tsis yog kev siv zog ntawm ib qho molecule, tab sis yog kev sib koom ua las voos ntawm cov khoom ntse, microbiome, thiab kev txawj ntse. Raws li tus yeej Nobel nqi zog hauv Chemistry, Frances Arnold, ib zaug hais tias, "Lub molecules nyob rau hauv cov xwm twb tuav infinite possibilities. Peb yuav tsum tau ua yog kawm kom mloog lawv 'lus ntawm lub sij hawm thiab qhov chaw'."
