Origin
E 310 is chemically produced in a chemical process for use as an antioxidant. Propylgallate has the positive property that it does not lose its antioxidative properties even under strong heating.
Usage
E 310 is primarily added as an additive to fat-rich foods, because it can prevent the fats contained in the food from becoming rancid under oxygen influence. The maximum allowed amount for food is 200 g per kilogram of fat. E 310 is mainly found in fatty baked goods and their fillings such as poppy seed or marzipan fillings. Sweets like nougat or marzipan may also contain E 310, as well as chewing gum and ready-made potato products like potato chips or french fries, further cake mixes, spices, and instant soups.
Risks
Propylgallate can trigger allergic reactions such as skin irritations or irritation of the oral mucosa. In infants, it can even lead to fatal cyanosis. Although E 310 is not approved for baby food, since it is a component of some ready-made baked goods and sweets, parents should be cautious.
