Propylene Glycol Alginate (PGA) is a food additive derived from alginic acid, a natural substance found in brown seaweed. It is commonly used in food production due to its thickening, stabilizing, and emulsifying properties. Here are key points about its use in food:

  1. Thickening Agent: PGA is often used to increase the viscosity of food products like sauces, dressings, and dairy-based beverages, giving them a smooth and consistent texture.

  2. Emulsifier: It helps to blend and maintain the mixture of water and oil in products such as salad dressings, preventing separation.

  3. Stabilizer: PGA helps to stabilize foams in beverages, particularly in beer and soft drinks, allowing them to maintain a frothy head.

  4. Acid Stability: It performs well in acidic conditions, making it ideal for use in fruit juices and carbonated drinks.
