| Physical and Chemical Properties | White amorphous powder. Tasteless and odorless. Easily soluble in water, dimethylformamide, does not produce gelation, the solution is viscous and stable, neutral. Insoluble in alcohol, ether, oil. The viscosity of the solution is the same as that of Arabic gum, and it has very good salt resistance, enzyme resistance, heat resistance, and thickening effect of pH change. The film is strong, and the film formed after the aqueous solution is dried on the metal plate has strong gas resistance to oxygen and nitrogen. It is easy to form a water-soluble edible film. It has good compatibility with other water-soluble polymer substances. |
| Use | Amylopectin is a glucose-based, highly-branched polysaccharide which together with amylose makes starch. The glucosidic bonds of amylopectin are α-1,4 in the glucan chain and α-1,6 at the branch points. Amylopectin from maize differs in structure |
| Introduction | pullulan is a glucan-like, xanthan gum extracellular water-soluble mucopolysaccharide, also known as pullulan, pullulan, English name Pullu-lan, transliterated for Pullulan. It is a special microbial polysaccharide discovered by R.Bauer in 1938. The polysaccharide is mainly composed of maltotriose linked by α-1,6 glycosidic bonds. The molecular weight is generally between 4.8x10 and 2.2x10 (the average molecular weight of commercial pullulan is 2x105. It consists of approximately 480 maltotriose). The polysaccharide has a unique structure and properties, the structure is elastic, and the solubility is relatively large. Pullulan film-forming, gas barrier, plasticity, viscosity are strong, and is easily soluble in water, non-toxic, harmless, colorless and tasteless and other excellent characteristics, in medicine, food, oil, chemical industry and other industries have broad application prospects. Because it can be degraded and utilized by microorganisms in nature, it will not cause environmental pollution, so it is known as pollution-free plastic. In May 19, 2006, the Ministry of Health issued the eighth announcement, pullulan is one of the four new food additive products, can be in the candy, chocolate coating, film, compound flavoring and fruit and vegetable juice drinks used as film and thickening agent. |
| Use | pullulan has been widely used in medicine, food, light industry, pullulan is one of the four new food additive products and can be used as a film covering and thickening agent in candy, chocolate coating, film, complex flavoring and fruit and vegetable juice beverages. The aqueous solution of pullulan has a smooth and refreshing feeling, and has the characteristics of improving the taste, so it can be used as a food quality improver and thickener. Adding a small amount of pullulan during food processing can significantly improve food quality. Such as fish cakes can enhance the flavor and quality; Bean curd when adding a small amount of pullulan can maintain the flavor of soybean and simplify the process; Soy sauce. A small amount of pullulan added to condiment, pickle, sugar-cooked fish and shrimp, delicious food can stabilize its viscosity, increase its viscous feeling and make its taste more smooth. thickener, stabilizer, coating agent, quality improver. Usually with carrageenan, locust bean gum and other combined, the dosage of 0.15% ~ 0.5%. Can be directly added to food to simplify the manufacturing process, prevent aging, give gloss, replacement of food in a part of the starch material, the manufacture of low calorie food. The coating can also be formed by spraying or dipping to prevent oxidation. The film product can be used as a transparent edible anti-oxidation packaging material which is stable at low temperature. pullulanase substrate pullulan has been used in studies to evaluate bone tissue engineering. It is also used in anti-fog applications. |
| Application | (1) pharmaceutical industry, cosmetic filler and adhesive forming agent. (2) food quality improver and thickener. (3) a water-soluble packaging material for preventing oxidation. (4) low-energy food raw materials of staple food and cake. Pullulan is a polysaccharide polymer composed of D-maltotriose units; Trisaccharides produced by digestion of Amalose by alpha-amalase. Pullulan has been used to evaluate bone tissue engineering studies. When the addition amount was 50%(wt.%), the addition of amylopectin increased the elongation at break of gelatin-based edible films. |
| safety | Based on the acute, subacute and chronic toxicity test, mutagenicity test results of pullulan, even if the dosage of pullulan reaches the limit of 15g/kg of LD50 (half lethal dose), it will not cause any biological toxicity and abnormal state, it is therefore safe for use in the food and pharmaceutical industries. |
| production method | in starch-containing hydrolysates (typically with maltose) and inorganic salts in the medium gas Culture (27~30 ℃,4~7 days) black yeast (pullulans pullulans such as pululans, also known as aureobasium pululans), and then heated, the bacteria were removed by centrifugation, and the filtrate was precipitated with an equal amount of ethanol, and then dissolved and purified with water. |
