1. Pullulan
Kopulan is also known as pullulan polysaccharide, CAS 9057-02-7, E number E1204, molecular formula (C6H10O5)n.
Pullulan polysaccharide is a kind of extracellular water-soluble mucopolysaccharide similar to glucan and xanthan gum produced by the fermentation of sprouting short-stalked mold, which is a special microbial polysaccharide discovered by R. Bauer in 1938.
2. Advantages of pullulan polysaccharide
The pullulan polysaccharide has two important properties: it is structurally flexible and has relatively large solubility.
The film-forming property, gas-blocking property, plasticity, and viscosity of Pullulan polysaccharide are strong, and it has excellent properties such as easily soluble in water, non-toxic and harmless, colorless, and tasteless, etc. It has been widely used in medicine, food, light industry, chemical industry, and petroleum.
3. Pullulan polysaccharide uses
1. Application in preserving agricultural products
Because of the good film-forming property, pullulan polysaccharide can be widely used in preserving agricultural products such as fruits, vegetables, and eggs.
2. Application in seafood preservation
Research shows that, as a new type of seafood film insulator, Pullulan polysaccharide can fully and effectively inhibit the accumulation of volatile salt-based nitrogen in seafood, and has a good protection effect on the evaporation of water in seafood.
3. Application in the food processing industry
It is widely used in the food industry as a low calorific value food material for staple foods and cakes, and as a food quality improver and plasticizer.
4. Application in the field of environmental protection
The product is applied to the purification and treatment of high turbidity water, the first-stage intensive treatment of urban sewage, and the treatment of wastewater in MSG production, forming a complete process and technology.
5. Application in the packaging industry
Pullulan polysaccharide is a non-ionic, non-reducing stable polysaccharide, thus it is easily dissolved in water and can be used as a viscous, neutral, non-dissociative non-gelatinized aqueous solution. The film made is transparent, colorless, odorless, non-toxic, with toughness, high oil resistance, edible, and can be used as food packaging. Its gloss, strength, and folding resistance are better than the film made from high chain starch.
