Taw qhia
Pullulan yog ib hom polysaccharide uas tsim los ntawm qee hom kab mob fungi. Nws yog ib qho khoom muaj nyob rau hauv ntau yam khoom noj, nrog rau cov khoom ci, khoom noj txom ncauj, thiab dej haus. Txawm li cas los xij, txawm hais tias nws siv dav, tseem muaj qee qhov kev sib cav ntawm cov kws paub txog kev noj qab haus huv txog seb puas yog rubulan puas yog digestible los ntawm tib neeg. Hauv tsab xov xwm no, peb yuav tshawb fawb txog kev tshawb fawb tom qab rubulan thiab nws cov digestibility, thiab tshuaj xyuas cov txiaj ntsig kev noj qab haus huv thiab kev pheej hmoo cuam tshuam nrog kev noj cov polysaccharide no.
Pullulan yog dab tsi?
Pullulan yog ib hom polysaccharide uas tsim los ntawm ntau hom fungi, suav nrog Aureobasidium pullulans. Nws yog cais raws li ib tug linear alpha-glucan, uas txhais tau hais tias nws yog tsim los ntawm rov qab units ntawm cov piam thaj molecule. Pullulan yog soluble hauv dej thiab muaj me ntsis, qab zib me ntsis. Nws feem ntau yog siv los ua cov thickener, stabilizer, thiab binder hauv cov khoom noj khoom haus, nrog rau hauv cov kws kho mob thiab lwm yam kev siv hauv kev lag luam.
Puas yog Pullulan Digestible?
Lub digestibility ntawm rubulan tau raug kev sib cav ntau ntawm cov kws paub txog kev noj qab haus huv. Qee qhov kev tshawb fawb qhia tias nws yog polysaccharide uas zom tau yooj yim, thaum lwm tus qhia tias nws tsis yooj yim zom los ntawm tib neeg.
Ib txoj kev tshawb fawb luam tawm nyob rau hauv Phau ntawv Journal of Food Science hauv 2011 tau tshuaj xyuas kev zom zaub mov ntawm rubulan hauv vitro. Cov kws tshawb fawb tau pom tias rubulan tau sai sai hydrolyzed los ntawm digestive enzymes, thiab tias cov piam thaj molecules tau nkag tau yooj yim los ntawm cov hnyuv. Qhov no qhia tau hais tias pullulan yog digestible heev los ntawm tib neeg.
Txawm li cas los xij, lwm txoj kev tshawb fawb luam tawm hauv tib phau ntawv xov xwm hauv xyoo 2013 pom tias rubulan tsis zom rau tib yam li lwm cov carbohydrates, thiab nws tau hloov pauv ntau yam tsis hloov pauv hauv cov quav. Cov kws tshawb fawb tau sau tseg tias qhov no yuav yog vim qhov tshwj xeeb ntawm cov qauv ntawm rubulan, uas muaj cov hlua ntev ntawm cov piam thaj molecules uas txuas ua ke hauv txoj kev txawv txav.
Cov txiaj ntsig tsis sib haum xeeb ntawm cov kev tshawb fawb no qhia tias kev tshawb fawb ntxiv yog xav tau kom nkag siab tag nrho cov digestibility ntawm rubulan los ntawm tib neeg.
Cov txiaj ntsig kev noj qab haus huv ntawm Pullulan
Txawm hais tias digestibility ntawm rubulan los ntawm tib neeg tseem yog ib qho kev sib cav, muaj ntau yam txiaj ntsig kev noj qab haus huv cuam tshuam nrog kev siv cov polysaccharide no.
1. Txo cov roj (cholesterol) siab
Ntau qhov kev tshawb fawb tau pom tias cov tshuaj rubulan tuaj yeem txo cov roj cholesterol hauv cov ntshav. Qhov no tej zaum yuav yog vim nws lub peev xwm los tsim cov tshuaj zoo li gel hauv plab, uas tuaj yeem khi rau cov kua tsib acids thiab tiv thaiv lawv qhov nqus. Cov kua tsib acids yog qhov tsim nyog rau kev zom cov rog, yog li los ntawm kev khi rau lawv, rubulan tuaj yeem ua rau lub cev zom cov roj cholesterol ntau.
2. Tswj cov ntshav qab zib
Qee cov kev tshawb fawb kuj qhia tias rubulan tuaj yeem pab tswj cov ntshav qab zib. Qhov no tej zaum yuav yog vim nws muaj peev xwm ua kom qeeb qhov nqus ntawm cov piam thaj hauv plab, uas tuaj yeem tiv thaiv cov ntshav qab zib tom qab noj mov. Ib txoj kev tshawb fawb luam tawm nyob rau hauv Phau Ntawv Qhia Txog Kev Ua Liaj Ua Teb thiab Khoom Noj Khoom Noj hauv xyoo 2006 tau pom tias rubulan txo qis glycemic Performance index ntawm qhob cij dawb.
3. Txhawb nqa lub plab Health
Pullulan kuj yog ib qho prebiotic, uas txhais tau hais tias nws ua zaub mov rau cov kab mob hauv plab. Qhov no tuaj yeem pab txhim kho plab hnyuv tag nrho thiab txo qhov kev pheej hmoo ntawm kev zom zaub mov. Ib txoj kev tshawb fawb luam tawm nyob rau hauv Phau ntawv Journal of Clinical Gastroenterology nyob rau hauv 2018 pom tau hais tias pullulan supplementation nce abundance ntawm ob peb lub plab kab mob nyob rau hauv cov neeg laus noj qab nyob zoo.
Kev Noj Qab Haus Huv Risks ntawm Pullulan
Txawm hais tias muaj ntau qhov txiaj ntsig kev noj qab haus huv cuam tshuam nrog kev noj cov pullulan, kuj tseem muaj qee qhov kev pheej hmoo uas yuav tsum tau xav txog.
1. Kev ua xua
Qee tus neeg yuav ua xua rau rubulan, thiab tej zaum yuav muaj cov tsos mob xws li khaus khaus, khaus, thiab ua pa nyuaj tom qab noj cov khoom uas muaj cov khoom xyaw no. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov tib neeg uas muaj keeb kwm ntawm pwm lossis cov kab mob fungal, vim tias cov kab mob rubulan yog tsim los ntawm qee hom kab mob fungi.
2. cuam tshuam nrog cov khoom noj khoom haus
Qee cov kev tshawb fawb qhia tias kev siv ntau ntawm cov rubulan tuaj yeem cuam tshuam nrog kev nqus ntawm qee yam khoom noj, xws li calcium thiab magnesium. Qhov no yuav yog vim nws lub peev xwm los khi rau cov zaub mov no thiab tiv thaiv lawv lub cev los ntawm lub cev.
3. Teeb meem digestive
Raws li tau hais ua ntej, kev zom zaub mov ntawm rubulan los ntawm tib neeg tseem yog ib qho kev sib cav. Qee tus neeg yuav ntsib teeb meem digestive xws li tsam plab, roj, thiab raws plab tom qab noj cov khoom uas muaj cov rubulan.
Xaus
Pullulan yog ib hom polysaccharide uas feem ntau siv los ua cov khoom xyaw hauv ntau yam khoom noj. Txawm hais tias nws txoj kev zom zaub mov los ntawm tib neeg tseem yog qhov kev sib cav, muaj ntau qhov txiaj ntsig kev noj qab haus huv cuam tshuam nrog kev siv cov polysaccharide no, suav nrog nws lub peev xwm txo qis cov roj cholesterol, tswj cov ntshav qab zib, thiab txhawb kev noj qab haus huv ntawm plab.
