What is propylene glycol alginate?

Propylene glycol alginate (PGA) is a food additive that is commonly used as a thickener, stabilizer, and emulsifier in a variety of processed foods. It is a derivative of alginic acid, which is a compound extracted from brown seaweed.

PGA is commonly used in dairy products, salad dressings, sauces, and gravies to improve texture and consistency. It helps to prevent ingredients from separating and also enhances the overall mouthfeel of the product.

In addition to its use in food, propylene glycol alginate is also used in certain pharmaceutical and cosmetic products as a thickening agent and emulsifier.

While propylene glycol alginate is generally regarded as safe for consumption, some individuals may be sensitive or allergic to it. It is always recommended to read product labels and consult with a healthcare professional if you have any concerns about consuming products that contain propylene glycol alginate.
