Sell Pullulan

Description

• Characteristics of Pullulan
  Pullulan is a colorless, tasteless and odorless polymer material and its characteristics can be expressed in the following aspects.
  
  ??Non-toxicity, Safety.
  Whether they are acute, subacute, chronic experiment or variation derived experiments, which has all shown pullulan does not cause any biological toxicity and abnormal conditions and it is safe and reliable used in food and pharmaceutical industries.
  ??Salt Resistance
  The salt content of any concentration doesn't affect the viscosity of pullulan solution. Therefore, it doesn't change because of the existence of salt used as a food additive.
  ??Acid and Alkali Resistance
  Pullulan is a neutral polysaccharide and its viscosity will decrease at room temperature in the case of hydrolysis ph<3.
  ??Viscosity
  Pullulan is structure of line shape, so its viscosity is far lower than that of other polysaccharides. The viscosity of pullulan solution increases with the average molecular weight and concentration, but compared with other polymer materials, the viscosity increase of pullulan solution is less and the thermal stability of its viscosity is better.
  ?? Plasticity
  Pullulan can be used in making films and arbitrary modeling because of its strong plasticity. The molding material of pullulan don't need to add plasticity and stability.
  ?? Films
  Pullulan directly make films, coated on the surface of objects or spray coating, which may all be films close to objects. The most special characteristic of pullulan films is lower permeability than other polymer films and oxygen, nitrogen, carbon dioxide, etc,. Can not almost completely pass. Films also have water vapor permeability. The films formed by pullulan 5% and glycerol 5% have high gas barrier and tensile strength.
   
• Usage of Pullulan
  ??The usage of pullulan based on different treatment processes as follows:
  1, Sterilization, decoloration and desalination materials of medium as pharmaceutical raw materials and their processing products.
  2, Sterilization, decoloration of medium as basic raw materials of food industry.
  3, Culture liquid or concentrate as agglutination and dispersing agents.
  ??The usage of pulluan based on different treatment process as follows:
  1, Filler and bond forming agent of pharmaceutical industry, cosmetics.
  2, Improvers and thickeners of food quality.
  3, Used in preventing oxidation of water -soluble packing materials.
  4, Food material with low heat of staple and pastry.
