Consumer Advice
Propylene glycol alginate (PGA) is a chemically modified ester of alginic acid. It thickens, stabilizes and emulsifies, and is especially good at stabilizing oily and acidic mixtures, so it is used to stabilize beer foam and appears in salad dressings, ice cream and acidic drinks. It is derived from seaweed and is generally recognized as safe at permitted levels, so normal consumption is not a concern.
