PGA Alginate Salts Powder Thickener Food Additive
1. Quick Detail :
PGA 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.
2. Description :
PGA ( the abbreviated name of Propylene glycol alginate ), 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.
