What It Does

Propylene Glycol Alginate (PGA) is a modified form of alginic acid extracted from brown seaweed. It is widely used in acidic systems like fruit juices, soft drinks, and dressings where other gums may precipitate. PGA not only stabilizes emulsions but also enhances foaming, thickens liquids, and improves suspension.
