Pullulan
Pullulan is a linear polysaccharide composed of maltotriose units linked by α-1,6 glycosidic bonds, produced through fermentation by the fungus Aureobasidium pullulans. This white, odorless, and tasteless powder is highly soluble in water, forming clear, flexible films with exceptional oxygen barrier properties and biodegradability, making it suitable for advanced material applications in controlled environments.
Pullulan
In the food sector, it serves as a stabilizer in low-calorie products and edible coatings for fruits; in pharmaceuticals, for vegetarian capsules and drug delivery systems; in cosmetics, as a binder in face masks; in biotechnology, for cell encapsulation; and in packaging, for eco-friendly films reducing spoilage in supply chains.
Classified as GRAS by FDA with no significant toxicity in standard doses; however, prolonged dust exposure may cause mild respiratory or eye irritation in industrial settings. Rare allergic reactions reported in sensitive workers; avoid mixing with strong acids to prevent degradation; always ensure proper ventilation and use dust masks during bulk transfers per occupational guidelines.
