Pullulan Polysaccharides Raw Materials Pullulan Polysaccharides powder
Product Overview:
Pullulan polysaccharide is a kind of extracellular water-soluble mucopolysaccharide similar to dextran and xanthan gum produced by the fermentation of sprouting short-stemmed mould, also known as short-stemmed mould polysaccharide, thrive mould polysaccharide, with unique structure and properties, structurally elastic, with relatively large solubility. 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 tasteless, etc., and it has a wide range of application prospects in pharmaceutical, food, petroleum, chemical and other industries.

Pullulan Polysaccharides Powder Usage and Synthesis.
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.
Uses of Pullulan Polysaccharides.
Thickener, stabiliser, film agent, quality improver. Generally often used with carrageenan, locust bean gum, etc., the amount of 0.15% to 0.5%. Can be added directly to the food to simplify the manufacturing process, to prevent aging, to give luste, replace some of the starchy raw materials in the food, the manufacture of low-calorie food. It can also be sprayed or impregnated to form a film to prevent oxidation. Its film products can be used as transparent edible antioxidant packaging materials which are stable under low temperature.
Pharmacological Action of Pullulan Polysaccharides.
Product Method of Bulk Pullulan Polysaccharides 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.
