Pullulan, an orally active, water-soluble linear glucosic polysaccharide, is derived from the polymorphic fungus Aureobasidium pullulans. Comprising maltotriose units connected by α-1,6 linkages, this amorphous slime matter finds extensive applications across diverse fields such as food, environment, pharmaceuticals, manufacturing, and electronics .

在 SD 大鼠研究中，Pullulan (1、5 和 10% 分散在饲料中；口服；62 周) 对存活率和体重无明显影响，未表现出慢性毒性 [4]。
