I-fiber yokudlaiwuhlobo lokudla olungakwazi ukudilizwa ama-enzyme wokugaya umzimba womuntu, alukwazi ukumuncwa umzimba wezinto ze-polysaccharide kanye negama elijwayelekile le-lignin.

Nakuba kunomehluko osobala ngamaprotheni, amafutha, amavithamini nezinye izakhi, kubaluleke kakhulu empilweni yomuntu, kuze kube yiminyaka yawo-1970, i-fiber yokudla yafakwa ngokusemthethweni emphakathini wokudla okunomsoco, obizwa ngokuthi "isakhi sesikhombisa", bese imakethe ikhombisa umkhuba omuhle wokukhula.

I-fiber yokudla, njenge-macronutrient ebalulekile empilweni yokugaya kwamathumbu, isibe isici esinempilo sokudla okunoshukela ophansi, amafutha aphansi, ikhalori ephansi kanye namaprotheni aphezulu.

Ngaphezu kwalokho, njengesithako esiluhlaza esingafakwa emikhiqizweni, izinzuzo eziyinhloko ze "fiber yokudla +" zihlanganisa ukusiza ukwandisa ukusutha, ukuthuthukisa impilo yamathumbu ngisho nokusetshenziswa emkhakheni wokunciphisa ushukela, ukuthuthukisa ukuthungwa nokuzinza kokudla, kukhona amandla amakhulu emakethe.

I-fiber yokudla ayigaywe yi-gastrointestinal tract futhi iya ngqo emathunjini amakhulu. Kunezinhlobonhlobo zama-probiotics emathunjini amakhulu, futhi i-fiber yokudla ingahlinzeka ngokwengxenye ukudla kwama-probiotics amathumbu, kodwa futhi ihlanze udoti wamathumbu, futhi inikeze indawo enhle yokwanda kwama-probiotics.

I-Polyglucose inezici ze-fiber yokudla encibilika emanzini kanye nama-prebiotics. Uma kuqhathaniswa ne-fiber yokudla engancibiliki, i-polyglucose inemisebenzi eminingi yezempilo kanye nezinzuzo zokucubungula.

Inezici zekhalori ephansi, ukuzinza, ukubekezelelana okuphezulu, njll, futhi ingasetshenziswa kabanzi ekudleni okuhlukahlukene, ikakhulukazi ekudleni okusebenzayo okufana namandla aphansi kanye ne-fiber ephezulu.

I-Polydextrose iyi-polysaccharide eyakhiwe nge-glucose engahleliwe e-crosslinked, eyakhiwe ngokuncibilika kanye ne-polycondensation ye-glucose kanye nenani elincane le-sorbitol ne-citric acid ekushiseni okuphezulu. Ngenxa yomehluko wezinga le-polymerization, isisindo samangqamuzana sisuka ku-162 kuya ku-15000, lapho isisindo samangqamuzana singaphakathi kwe-5000 sibalwa ku-88.7%.

1. Ukudla okuvamile:Ngomhla zingama-28 kuNovemba 2014, impendulo yoMnyango Wokudla Kazwelonke Wezempilo kanye Nokuhlelwa Komndeni ezindabeni ezihlobene ne-polydextrose yabonisa ngokucacile ukuthi i-polydextrose ingaphathwa njengento evamile yokudla eluhlaza.

2. Izithasiselo zokudla:"I-GB2760 Food Safety National Standard Food izithasiselo zisebenzisa okujwayelekile" ibala i-polyglucose njenge-ejenti ejiyayo, i-ejenti yokuvuvukala, i-ejenti yokugcina umswakama, i-stabilizer, ukusetshenziswa kwebanga elibanzi, futhi elingenamkhawulo.
a.Lawula amathumbu: i-polyglucose ingasetshenziswa amagciwane emathunjini ukuvubela isikhutha, i-methane kanye ne-SOFA (ama-acids ashubile). Izingxenye eziyinhloko ze-SCFA bekuyi-butyrate futhi i-propionate ngendlela ye-isotopic tracer. Amagciwane e-Colon angasebenzisa i-butyrate ukulawula indawo yawo yamathumbu futhi avimbele ukwakheka kwamangqamuzana omdlavuza. I-Propionate ingavimbela ukwakheka kwe-cholesterol esibindini, ithuthukise i-glucose metabolism, ivuse i-glycolysis futhi ivimbele i-gluconeogenesis.
b.Yehlisa i-triglycerides ne-cholesterol: i-polyglucose ingavimbela i-triglyceride ne-cholesterol ukuthi ingangeni kuma-lymphatic capillaries. Ngasikhathi sinye, imikhiqizo yokuwohloka kwayo ngama-microorganisms amathumbu nayo ingavimbela ukwakheka kwe-cholesterol, ikhangise i-metabolite ye-cholesterol bile acid futhi iyikhiphe emzimbeni, ngaleyo ndlela inciphise okuqukethwe kwe-cholesterol emzimbeni womuntu futhi ivimbele ukwakheka kwamatshe enyongo.
c.Ukulawulwa kosizo nokuncipha kwesisindo: i-polyglucose ingakha ifilimu odongeni lwamathumbu, isonge amafutha ekudleni, inciphise ukumuncwa kwamafutha emgudwini wokugaya ukudla, ikhuthaze ukuphuma kwezinto ezingama-lipid, ukuze kuncishiswe ukunqwabelana kwamafutha, kuzuzwe umphumela wokuvimbela ukukhuluphala futhi kungacindezela isifiso sokudla, kunciphise ukudla, kuthuthukise ukusutha.
d.Ukukhuthaza ukumuncwa kwamaminerali Ucwaningo ku-Journal of Nutrition lwembula okokuqala ukuthi ukumuncwa kwe-calcium ye-jejunum, ileum, cecum kanye namathumbu amakhulu amagundane kwenyukile ngokwanda kokugcwala kwe-polyglucose phakathi kuka-0-100mmol/L.
Ukwengezwa kwe-polyglucose ekudleni kungakhuthaza ukumuncwa kwe-calcium emathunjini, mhlawumbe ngenxa yokuthi i-polyglucose ivutshelwa emathunjini ukuze ikhiqize ama-acid e-short-chain fatty, eyenza imvelo yamathumbu ibe ne-asidi, futhi indawo ye-acidification yandisa ukumuncwa kwe-calcium.
futhi.Ukukhipha ubuthi emzimbeni futhi kuthuthukise ukungatheleleki kwe-polyglucose kunganciphisa umsebenzi we-α-benzopyrene hydroxylase, kunciphise ukulimala kwe-benzopyrene ohlelweni lokugaya ukudla, kuthuthukise izinga lokusulwa komzimba kwama-biphenyl ane-polychlorinated, futhi kungakhuthaza nama-dioxins omzimba ngendlela yokuphuma kwendle. U-Ouk wondle amagundane i-polydextrose ku-3% wokudla kwansuku zonke futhi wathola ukuthi umthamo we-fecal wanda, isikhathi sokuhamba kwe-fecal emathunjini sehla, futhi izinga lokushisa le-fecal liyenyuka. U-Tomlin no-Read baphinde bathola ukuthi i-polyglucose yandisa ukuphuma kwe-fecal futhi yathambisa.
