Is e330 vegan?

E330 is the European code for citric acid, an organic acid commonly used in food processing. While it occurs naturally in citrus fruits, commercial citric acid is almost exclusively manufactured through industrial microbial fermentation. In this process, the mold Aspergillus niger is cultured on carbohydrate-rich plant substrates, such as molasses, corn starch, or sugar cane syrups. The resulting citric acid is subsequently filtered, isolated, and crystallized for use as a food additive.

This ingredient functions primarily as an acidity regulator, preservative, and flavoring agent. It is widely used across the food industry and can be found in soft drinks, fruit juices, candies, canned vegetables, jams, sauces, and baked goods.

E330 is classified as vegan because its production relies entirely on plant materials and microbial cultures. No animal tissues, dairy, or animal-derived processing aids are utilized during its fermentation, extraction, or purification. Because the commercial synthesis relies strictly on plant and microbial sources, E330 is suitable for a vegan diet.
