Pullulan is a kind of extracellular water-soluble mucous polysaccharide similar to dextran and xanthan gum produced by the fermentation of aureobasidium pullulans.The polysaccharide is a linear polysaccharide formed by polymerizing repeating units of maltotriose linked by α-1,4 glycosidic bonds through α-1,6 glycosidic bonds, with a molecular weight of 20,000-2 million and a degree of polymerization of 100-5,000.(The molecular weight of general pullulan commodities is about 200,000. There are about 480 maltotrioses.)On May 19, 2006, the Ministry of Health issued Announcement No. 8: Pullulan is one of the four new food additives.It can be used as coating agent and thickener in candy, chocolate coating, film, compound seasoning and fruit and vegetable juice beverage.
      The pullulan produced by our company is characterized by being a plant-based biological polysaccharide.It has good film-forming gel properties, oxygen barrier properties, gas barrier properties and stability, and has good solubility. It can be quickly dissolved in warm or cold water, and its dissolution rate is faster than carboxymethylcellulose, sodium alginate, polypropylene glycol and polyvinyl alcohol are more than 2 times faster.It is a non-digestible carbohydrate that is not absorbed by the intestinal tract and can be excreted from the body. Therefore, it will not cause diseases such as high blood pressure, heart disease and obesity, so it is a healthy food material.And it has been fully recognized and praised in the fields of medicine, food, light industry, chemical industry and petroleum.
