What is Propylene Glycol Alginate(PGA)？

Propylene Glycol Alginate (PGA) is a food additive derived from the alginic acid of brown seaweed. It is commonly used as a thickener, stabilizer, and emulsifier in food and cosmetic products, and helps to prevent ingredients from separating. It is a clear, odorless, and tasteless liquid with a viscosity that increases with concentration.

How to made Propylene Glycol Alginate(PGA)？

Propylene Glycol Alginate (PGA) is made by esterifying alginic acid, which is derived from brown seaweed, with propylene glycol. This process can be done through chemical reactions that involve the use of chemical reagents such as sodium carbonate and propylene oxide.

The appearance of Propylene Glycol Alginate(PGA)？

Propylene Glycol Alginate (PGA) is a white to pale yellow, fine, free-flowing powder that is soluble in water and has a slightly sweet taste. It is a gelling agent derived from the reaction between alginic acid and propylene glycol.

The active ingredient of Propylene Glycol Alginate(PGA)？

Propylene Glycol Alginate (PGA) is a food ingredient derived from brown seaweed. Its active ingredient is a polysaccharide called alginic acid, which has been esterified with propylene glycol.
