PROPYLENE GLYCOL ALGINATE(PGA)

FUNCTIONAL CHARACCTERISTICS

Propylene glycol alginate (abbreviated as PGA), is derived from alginic acid which is extracted from natural seaweed. It is in the form of white or 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.

Chemical structure

Main application

1.In food industry, 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 fronting and emulsifying ability. Widely used as a stabilizer for yoghurt, flavoring and beer foam.
4.PGA has the property of hydration, anti-aging and tissue improvement, which is use for raw and dried noodles, fresh dough products, convenient rice noodles, frozen rice noodles, bread, pastry and other baked food.
