High Viscosity Food Grade Propylene Glycol Sodium Alginate For Hydration , PGA
1. Quick Detail :
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.
2. Description :
Propylene glycol alginate is an emulsifier, stabilizer, and thickener used in food products. It is a food additive with E number E405. Chemically, propylene glycol alginate is an ester of alginic acid, which is derived from kelp. Some of the carboxyl groups are esterified with propylene glycol, some are neutralized with an appropriate alkali, and some remain free.
3. Applications :
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 frothing and emulsifying ability. Widely used as a stabilizer for yoghurt, flavoring and beer foam.
