PGA is commonly used to combine ingredients that aren’t normally able to mix together on their own
Derived from brown kelp, Propylene Glycol Alginate (PGA) is an odorless fully plant-based ingredient used as a food preservative, emulsifier, stabilizer, and thickener that can actually be found in numerous types of foods. You can find it in dairy products, salad dressing, bread, sauces, baking mixes, fruit, lactic acid beverages, instant food, certain alcoholic beverages, and countless other products. PGA is used to prevent ingredients from separating, improve a food’s flavor and appearance, and to modify its texture. Salad dressings usually contain oil- and water-based ingredients, and without an emulsifying agent, the ingredients would remain separate, which will affect its taste, consistency, and texture. Without PGA, we wouldn’t be able to enjoy many of our favorite foods!
