Vegetable gelatin- Hydroxypropyl alginate 1.Viscosity:50-1200mpa.s 2.water solulable and gel 3.Other name: PGA

Vegetable gelatin- Algin

Other name:  Propylene glycol alginate (PGA) :

white powder and it is easy to dissolved in water and its water solution become gel

 

Propylence glycol alginate(abbreviated as PGA),is derived from alginic acid which is extracted from natural seaweed.It is in the from of white of flaxen powder.Aqueous solution is viscous colloid.Compared with alginate,it has better resistance against acid and salts.And PGA is a good seaweed based food additive which has excellent performance.

 MAIN APPLICATIONS1, In food insustry,used as thickener,emulsifier and stabilizer.

2, PGA has good acid-proof property,can be used in conditions with PH at 3-5.

3,PGA has strong frothing and emulsifying ability.Widely used as a stabilizer for yoghurt,flavoring and beer foam.
