Pullulan(CAS: 9057-02-7)

Pullulan is a natural polysaccharide produced by the bacterium Aureobasidium pullulans. It has the chemical formula (C6H10O5)n and is composed of maltotriose units linked by α-1,6 glycosidic bonds. Pullulan is known for its biodegradability, non-toxicity, and water-solubility, making it a versatile compound used in various applications.

Pullulan is widely used in pharmaceuticals as a binder and film former, in food industry as a thickener and stabilizer, in biotechnology for drug delivery systems, and in research for its applications in nanotechnology and as a model for studying polysaccharide structure. It is also used in packaging and as a substitute for synthetic materials due to its biocompatible properties.

Pullulan is considered safe for use in food, pharmaceutical, and industrial applications. It is non-toxic and has been approved by regulatory bodies such as the FDA. However, proper handling is recommended to avoid inhalation or skin contact, especially in industrial settings. Safety standards ensure its use in controlled environments to maintain quality and minimize risks.

Pullulan should be stored in a cool, dry place away from direct light. It is typically kept in airtight containers to prevent moisture absorption and contamination. The optimal storage temperature is between 15°C to 25°C, and maintaining low humidity levels is essential to preserve its stability and functional properties over time.
