Pullulan
Pullulan is an extracellular water-soluble mucopolysaccharide similar to glucan and xanthan gum produced by the fermentation of Aureobasidium pullulans, also known as pullulan and pullulan. The polysaccharide is mainly composed of maltotriose linked by α-1,6 glycosidic bonds. Pullulan has a unique structure and properties, elastic in structure and relatively high solubility. The polysaccharide has wide application prospects in medicine, food, petroleum, chemical industry and other industries. Because it can be degraded and utilized by microorganisms in nature and will not cause environmental pollution, it is known as pollution-free plastic. Uses: ·fillers and bonding agents for the pharmaceutical industry, cosmetics ·food quality improvers and thickeners ·water-soluble packaging material for oxidation prevention.
