used as a food additive, primarily as an antioxidant and preservative

Propyl gallate is also used as a food additive, primarily as an antioxidant and preservative. Here are some key points about its use in food:

Antioxidant activity: Propyl gallate is an effective antioxidant that helps to prevent the oxidation of fats and oils in food products. This helps to extend the shelf life of products by preventing rancidity and off-flavors.

Food applications:

Fats and oils (vegetable oils, animal fats, butter, margarine)

Baked goods (bread, cakes, pastries)

Snack foods (chips, crackers, nuts)

Chewing gum

Meat products

Fried foods

Beverages (beer, wine, soft drinks)

Preservative function: In addition to its antioxidant properties, propyl gallate also exhibits antimicrobial activity, making it useful as a preservative in food products to inhibit the growth of bacteria, molds, and other microorganisms.

Concentration: The typical concentration of propyl gallate used in food products ranges from 0.01% to 0.1%, depending on the specific food product and desired antioxidant and preservative effects.
