Hot Sale Propylene Glycol Alginate

Propylene glycol alginate is an important chemically modified alginate, which is esterified by the reaction of natural alginate (mainly from brown algae) and propylene oxide. This modification gives propylene glycol alginate many unique properties, so that it is widely used in food, pharmaceutical, daily chemical and other industrial fields.Propylene glycol alginate is usually a white or light yellow fibrous or granular powder. Propylene glycol alginate is easily soluble in cold or hot water, forming a viscous colloidal solution, insoluble in ethanol, chloroform and other organic solvents and strong acidic solutions with pH lower than 3.Using alginate, starting from product taste improvement, cost control, process optimization, and the provision of healthy concept terminal products and many other industry problems and needs, to provide users with systematic solutions, create cost-effective products, enhance the competitiveness of enterprise products industry, improve the profit of enterprise products, and then achieve user satisfaction.

Advantages:

• Excellent acid resistance and stability: Part of the carboxyl group on the molecular chain of propylene glycol alginate is esterfied, reducing its ionization degree and sensitivity to hydrogen ions, so that it can maintain solubility and stability at a lower pH value, without gelation or precipitation. This makes propylene glycol alginate ideal for use in acidic beverages and foods.

  
  

• Good emulsification and bubble stability: The hydrophilic (carboxyl group, hydroxyl group) and hydrophobic (propylene glycol group) parts of its molecular structure make it an effective hydrophilic colloidal emulsifier. It can adsorb to the oil-water interface, reduce the interfacial tension, and help form and stabilize the emulsion.

  
  

• Thickening and pseudoplasticity: Propylene glycol alginate solution has a significant thickening effect, which can improve the viscosity and texture of the product. Its solution usually exhibits pseudoplasticity (shear thinning), that is, the viscosity is reduced when stirring or pumping, and it is easy to process; The viscosity is recovered at rest, providing good suspension stability and taste.

  
  

• Film forming: PGA can form a film on the surface, which can be used as a coating or protective layer.
