Pullulan polysaccharides are polysaccharide polymers consisting of D-maltotriose units; trisaccharides produced by digestion of Amalose by α-Amalase. Pullulan polysaccharide has been used in studies to evaluate bone tissue engineering. The incorporation of branched starch increased the elongation at break of gelatin-based edible films when added at 50% (wt.%).

Uses and functions of Pullulan.

Pullulan polysaccharide has been widely used in medicine, food, light industry, chemical industry, Pullulan polysaccharide is one of the new four food additives products, which can be used as filming agent and thickening agent in confectionery, chocolate coating, film, compound flavouring section and fruit and vegetable juice beverage. The aqueous solution of Pullulan polysaccharide has a smooth and refreshing feeling, with the characteristics of improving taste, so it can be used as a food quality improver and thickener.

Adding a small amount of Pullulan polysaccharide in the process of food processing can significantly improve the quality of food. Such as fish cake can enhance the taste and quality; the system of tofu when adding a small amount of Pullulan polysaccharide can maintain the flavour of soybeans and simplify the process; soy sauce. Seasonings, salted vegetables, fish and shrimp cooked in sugar, delicious food, etc. A small amount of added pullulan polysaccharide can stabilise its viscosity, increase its viscosity and make its taste smoother.

Pullulan has a unique structure and properties, structurally elastic and relatively soluble. The film-forming, gas-blocking, plasticity and viscosity of Pullulan polysaccharide are strong, and it has excellent characteristics such as soluble in water, non-toxic, harmless, colourless and odourless, etc., which has a wide range of application prospects in the industries of pharmaceuticals, food, petroleum, chemical industry, etc. It can be degraded and utilized by microorganisms in the natural world without causing environmental pollution. Because it can be degraded and utilised by microorganisms in nature and will not cause environmental pollution, it is known as pollution-free plastic.

Preparation method of Pullulan.

Product method of Bulk Pullulan Powder.

In the medium containing starch hydrolysate (usually with caramel) and inorganic salts in the aeration culture (27 ~ 30 ℃, 4 ~ 7 days) black yeast (sprouting short-stemmed mould Pullular such as pullulans, also known as AureobasidIumpullulans), and then heating, centrifugal separation to remove the bacterial body, the filtrate with an equal amount of ethanol to make the precipitation, and then dissolved in water to obtain the refinement. The filtrate is precipitated with equal amount of ethanol and then refined by dissolving with water.
