Propylene Glycol Alginate (PGA)

Propylene Glycol Alginate (PGA)

Propylene Glycol Alginate (PGA) is an ester of alginic acid, derived from brown seaweed, and food additive used to stabilize, thicken, and emulsify. Brown seaweeds have been used as a food for centuries.

Propylene Glycol Alginate helps give products a smooth and natural texture and taste even under reduction conditions, such as in yogurt.

Propylene Glycol Alginate helps give products a glossy and smooth appearance.

Propylene Glycol Alginate can mix well with other ingredients and can be applied during the fermentation process in any range of pH value. Further, PGA improves dispersibility and solubility in products, and is heat stable.

Propylene glycol alginate not only acts as a stabilizing agent, but emulsifies.

Thus Alginates can provide solutions having a range of viscosities or gels of varying rigidities which may be used as texture modifiers in a wide range of food applications.
