Pullulan
Pullulanhmoov yog ntuj dej-soluble polysaccharide, fermented los ntawm AuveobasidiumPullulans.Nws muaj feem ntau ntawm maltotriose units txuas los ntawm α-1,6-glucosidic bonds.Qhov nruab nrab molecular hnyav yog 2 × 105 Da.
Pullulan hmoov tuaj yeem tsim ua ntau yam khoom.Nws yog ib qho zoo heev zaj duab xis-yav dhau los, ua ib zaj duab xis uas yog tshav kub sealable nrog zoo oxygen barrier zog.Nws tuaj yeem siv dav hauv kev lag luam kws tshuaj thiab khoom noj khoom haus, xws li cov tshuaj encapsulating, nplaum, thickening, thiab txuas ntxiv.
Pullulan hmoov tau siv los ua khoom noj khoom haus rau ntau tshaj 20 xyoo hauv Nyiv.Nws tau pom zoo raws li Kev Nyab Xeeb (GRAS) hauv Teb Chaws Asmeskas rau ntau yam kev siv ntau dua.
