Is l-ascorbic acid e300 vegan?

L-ascorbic acid, designated by the European food additive code E300, is the common chemical name for vitamin C. While it occurs naturally in many fruits and vegetables, the commercial additive is manufactured on an industrial scale. It is produced primarily from plant-derived glucose, typically extracted from corn, wheat, or cassava starch, through a multi-step method combining bacterial fermentation and chemical synthesis. Food producers use E300 as an antioxidant, acidity regulator, and flour treatment agent across a wide range of items, including fruit juices, bread, canned goods, and carbonated beverages.

This ingredient is vegan because its commercial production relies entirely on plant materials, microbial cultures, and synthetic reagents. Animal-derived substances, byproducts, and processing aids are not used at any stage of the standard manufacturing process. Therefore, l-ascorbic acid E300 contains no animal sources and is suitable for a vegan diet.
