Applications of Pullulan

Pullulan is a water-soluble viscous polysaccharide, typically produced as a white solid powder. Due to its excellent film-forming, fiber-forming, gas-barrier, adhesive, and processability properties, as well as being non-toxic, it is widely used in pharmaceuticals, food, light industry, chemicals, and petroleum sectors. The main application areas of pullulan include:

(1) Pharmaceuticals and Health Products: Used in capsule production and as a binding and forming agent in cosmetics.

(2) Food Industry: Serves as a quality improver and thickener.

(3) Oxidation Prevention: Applied in water-soluble packaging materials to prevent oxidation.

(4) Low-Calorie Food Ingredients: Used as a low-calorie raw material for staple foods and pastries.

Application in Agricultural Product Preservation

Due to its excellent film-forming properties, pullulan is widely used for preserving fruits, vegetables, eggs, and other agricultural products.

Application in Seafood Preservation

Studies have shown that pullulan, as a novel coating preservative for seafood, effectively inhibits the accumulation of volatile basic nitrogen in seafood and provides excellent protection against moisture evaporation.

Application in Food Processing Industry

As a low-calorie food ingredient for staple foods and pastries, as well as a quality improver and plasticizer, pullulan is extensively used in the food industry.

Application in Environmental Protection

Pullulan is employed in the purification of high-turbidity water, primary enhanced treatment of urban wastewater, and the treatment of wastewater generated during monosodium glutamate production, forming a complete set of processes and technologies.

Application in Packaging Industry

Pullulan is a non-ionic, non-reducing stable polysaccharide, making it easily soluble in water. It can be used as a viscous, neutral, non-ionic non-gelling aqueous solution. Films made from pullulan are transparent, colorless, odorless, non-toxic, flexible, highly oil-resistant, and edible, making them suitable for food packaging. Their gloss, strength, and foldability are superior to films made from high-amylose starch.
