Cov kev tshawb fawb tau pom tias prebiotics tuaj yeem txhawb kev loj hlob ntawm probiotics, yog li cas yog prebiotics? Lub tswv yim ntawm prebiotics tau pom thawj zaug hauv xyoo 1995. Nws yog cov khoom xyaw uas tsis tuaj yeem zom tau los ntawm tib neeg lub cev, tuaj yeem tiv thaiv kab mob plab, thiab tsis nqus los ntawm enzymes thiab plab hnyuv. Xyoo 2016, Lub Koom Haum International Probiotics thiab Prebiotics Science Association tau rov txhais cov tshuaj prebiotics raws li cov khoom siv uas tuaj yeem xaiv siv thiab hloov pauv los ntawm tus tswv tsev lub plab hnyuv ntawm qhov chaw uas muaj txiaj ntsig zoo rau kev noj qab haus huv ntawm tus tswv tsev. Cov kev tshawb fawb yav dhau los suav hais tias prebiotics li oligosaccharide carbohydrates. Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau pom tias prebiotics suav nrog tsis yog cov carbohydrates xwb tab sis kuj tseem muaj lwm cov carbohydrates uas ua tau raws li cov qauv prebiotics, xws li polyphenols thiab peptide polymers.
Feem ntau siv prebiotics muaj xws li oligosaccharides, suav nrog fructooligosaccharides, galactooligosaccharides, xylooligosaccharides, isomaltooligosaccharides, soybean oligosaccharides, inulin, thiab lwm yam. Qee cov microalgae kuj tseem siv tau los ua prebiotics, Arthrogas, thiab lwm yam. xws li versicolor polysaccharide , zaub ntug hauv paus nitrogen-muaj polysaccharide), protein hydrolysates (xws li casein hydrolysates, -lactalbumin, lactoferrin, thiab lwm yam) thiab zaub los ntawm tej yam ntuj tso nroj tsuag, Suav tshuaj ntsuab, cov nroj tsuag qus, thiab lwm yam kuj yuav siv tau raws li prebiotics.
Prebiotics tuaj yeem txhawb kev loj hlob thiab metabolism ntawm probiotics. Muaj ntau ntau cov kev tshawb fawb ntawm prebiotics txhawb kev loj hlob thiab kev loj hlob ntawm probiotics, tab sis feem ntau ntawm lawv tsom rau polysaccharide-based prebiotics. Piv txwv li, qee cov kws tshawb fawb txawv teb chaws tau tshawb fawb txog enteropolysaccharides thiab pom tias enteropolysaccharides tuaj yeem hloov pauv cov kab mob plab hnyuv loj ntawm C57BL / 6J nas thiab txhawb kev loj hlob ntawm probiotics. Ntxiv nrog rau polysaccharide prebiotics, polyphenols tuaj yeem xaiv txhawb kev loj hlob ntawm cov kab mob probiotic. Piv txwv li, cov phenolic tebchaw (xws li catechin, gallic acid, vanillic acid, thiab protocatechuic acid) muaj nyob rau hauv txiv nkhaus taw tuaj yeem inhibit qhov kev loj hlob ntawm cov kab mob pathogenic thiab muaj txiaj ntsig zoo rau kev loj hlob thiab kev loj hlob ntawm probiotics.
Prebiotics tseem tuaj yeem txhawb nqa cov kab mob probiotic tiv thaiv rau cov kab mob oxygen thiab cov kua tsib ntsev / kua qaub. Cov kev tshawb fawb tau pom tias qhov tsim nyog ntawm cov pa oxygen reactive muaj txiaj ntsig zoo rau tib neeg kev noj qab haus huv. Txawm li cas los xij, ntau hom kab mob reactive oxygen nyob rau hauv cov hnyuv tuaj yeem cuam tshuam nrog DNA, proteins, thiab lipids hauv cell membranes ntawm txoj hnyuv probiotics, uas yog kev puas tsuaj rau ntau haiv neeg thiab ciaj sia ntawm txoj hnyuv probiotics. Kev npam. Nws tau raug tshaj tawm tias cov tshuaj prebiotics xws li fructans, cog polyphenols, inulin, thiab daj polysaccharides tuaj yeem tshem tawm cov pa oxygen dawb hauv cov kab mob plab thiab qhia txog kev tiv thaiv ntawm probiotics. Tsis tas li ntawd, feem ntau probiotics nyob rau hauv txoj hnyuv yog heev rhiab heev rau cov kua tsib ntsev / kua qaub, uas yuav inhibit qhov kev loj hlob thiab kev ua ntawm probiotics los ntawm oxidative kev nyuaj siab, dissolving kab mob daim nyias nyias, thiab puas DNA. Cov kev tshawb fawb tau pom tias cov kua tsib ntsev tuaj yeem degraded los ntawm prebiotics, yog li txo cov tshuaj lom ntawm cov kua tsib ntsev ntawm probiotics.
Prebiotics kuj tseem tuaj yeem ua cov tshuaj tiv thaiv hauv kev npaj cov tshuaj probiotics. Cov txheej txheem khov-qhuav ntawm probiotics yuav ua rau lawv lub cev muaj peev xwm txo qis, yog li cov neeg ua haujlwm tiv thaiv yuav tsum tau hloov pauv qhov chaw nyob ntawm probiotics, txo kev puas tsuaj rau cov hlwb, thiab tswj hwm tus yam ntxwv ntawm lub cev thiab biochemical thiab kev ua haujlwm lom ntawm cov kab mob ntau npaum li cas. ua tau. Prebiotics yog ib qho tshuaj tiv thaiv uas siv ntau. Qee cov kws tshawb fawb tau pom tias cov protein trehalose tuaj yeem txhim kho qhov muaj sia nyob ntawm Lactobacillus plantarum TISTR 2075 tom qab khov-qhuav. Piv nrog rau lwm cov tshuaj tiv thaiv, txawm tias nyob rau hauv lub sij hawm ntev cia, cov protein-trehalose tiv thaiv tus neeg sawv cev tseem tuaj yeem tuav cov kab mob uas muaj peev xwm thiab cov kab mob probiotic tsawg tshaj plaws.
Hauv cov ntsiab lus, prebiotics tuaj yeem txhawb kev loj hlob thiab cov metabolism hauv probiotics, txhawb kev tiv thaiv ntawm probiotics rau reactive oxygen hom thiab cov kua tsib ntsev / kua qaub, thiab tseem tuaj yeem siv los ua cov tshuaj tiv thaiv hauv kev npaj cov tshuaj probiotics, thiab tuaj yeem siv rau hauv cov zaub mov noj qab haus huv, chaw kho mob. , thiab lwm yam teb, kom ua tiav lub hom phiaj ntawm kev tiv thaiv qee yam kab mob, tswj tib neeg kev noj qab haus huv, thiab nce tus naj npawb ntawm probiotics.
