Pullulan yog ib qho zoo kawg nkaus polysaccharide uas muaj ntau yam txiaj ntsig hauv ntau yam kev siv.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm rubulan yog nws lub cev tshwj xeeb. Nws yog cov xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj ntxhiab tsw uas tsim tau yooj yim, pob tshab zaj duab xis. Qhov no ua rau nws zoo tagnrho rau ntim khoom noj vim nws tiv thaiv cov zaub mov los ntawm ya raws, oxygen, thiab lub teeb thaum tseem ua rau cov khoom pom. Pullulan films kuj tseem muaj cua sov sealable, uas ua rau lawv yooj yim rau siv nyob rau hauv cov txheej txheem ntim.
Ntxiv nrog rau cov ntawv ntim khoom, rubulan muaj ntau yam txiaj ntsig hauv kev kho mob. Nws yog non-toxic thiab biocompatible, ua rau nws muaj kev nyab xeeb rau kev siv hauv cov khoom siv kho mob thiab kev xa tshuaj. Pullulan tuaj yeem siv los encapsulate cov tshuaj, tiv thaiv lawv los ntawm degrading thiab ua kom lub hom phiaj xa mus rau qee qhov ntawm lub cev. Nws tseem tuaj yeem siv los tsim cov ntaub so ntswg engineering scaffolds uas muab cov qauv kev txhawb nqa rau kev loj hlob ntawm tes thiab rov tsim dua tshiab.
Pullulan kuj zoo rau ib puag ncig. Nws yog biodegradable thiab compostable, txhais tau hais tias nws tuaj yeem raug rhuav tshem los ntawm cov kab mob, txo cov khib nyiab thiab ib puag ncig cov pa phem. Pullulan tuaj yeem tsim los ntawm cov khoom siv txuas ntxiv dua tshiab xws li cov hmoov txhuv nplej siab, ua rau nws muaj txiaj ntsig zoo rau cov khoom siv yas.
Lwm qhov zoo ntawm pullulan yog nws cov versatility. Nws tuaj yeem hloov kho thiab ua haujlwm kom tau raws li cov kev xav tau tshwj xeeb, xws li kev txhim kho nws cov solubility, adhesion lossis mechanical zog. Qhov no tso cai rau nws siv rau ntau yam kev siv, los ntawm cov khoom noj thiab tshuaj pleev ib ce mus rau kws tshuaj thiab biotechnology.
Hauv kev lag luam khoom noj khoom haus, rubulan yog siv los ua cov thickener, stabilizer thiab emulsifier. Nws tuaj yeem txhim kho kev ntxhib los mos thiab ruaj khov ntawm cov khoom noj xws li kua ntses, condiments thiab khoom qab zib. Pullulan kuj tseem siv tau los ua cov yeeb yaj kiab thiab cov txheej txheem, uas tuaj yeem txuas lub neej txee ntawm cov khoom tshiab thiab tiv thaiv nws los ntawm kev lwj.
Hauv cov tshuaj pleev ib ce, rubulan yog siv los ua tus humectant thiab zaj duab xis qub. Nws tuaj yeem pab ua kom daim tawv nqaij hydrated thiab du thaum tseem muab kev tiv thaiv kev tiv thaiv ib puag ncig kev ntxhov siab. Pullulan tseem tuaj yeem siv rau hauv cov khoom tu plaub hau xws li tshuaj zawv plaub hau thiab cov tshuaj kho kom zoo dua qub kom tswj tau thiab ci ntawm cov plaub hau.
