Erythorbic acid

Other names: Erythorbic acid, E315

Erythorbic acid, also known as Erythorbic acid or referred to as E315 in food terminology, is a synthetic form of vitamin C and is used significantly as an antioxidant in the food industry. Its main function is to prevent oxidation of fats and vitamins, which would lead to their deterioration and food spoilage.

What products is this antioxidant added to? Erythorbic acid is often used in beverages, specifically fruit juices, energy drinks or caffeinated drinks. It can also be found in canned fruit and vegetables, jams and marmalades, ice cream, confectionery and many other products. It is preferable for manufacturers to use erythorbic acid, especially for products that have a longer shelf life and could oxidise during storage. This acid helps foods to maintain freshness, retain their original colour and, above all, extend their shelf life. However, it may also be present in cosmetic products, where it helps to stabilise the product and contribute to its shelf life.
