E305 – Ascorbyl stearate
AntioxidantsDescription
White to yellowish-white powder or solid with a citrus-like odor
Notes
Ascorbyl stearate is created by combining ascorbic acid (vitamin C) with stearic acid, a fatty acid commonly found in animal fats and plant oils like cocoa butter and shea butter. This combination creates a fat-soluble version of vitamin C that appears as a white to yellowish-white powder. While regular vitamin C dissolves in water, this modified version can work in fatty environments where regular vitamin C cannot. This additive functions as an antioxidant, preventing fats and oils in food from going rancid and maintaining freshness and quality. Because it can work in fatty foods where regular vitamin C would be ineffective, you'll find ascorbyl stearate in products like margarine, cooking oils, processed meats, snack foods, and baked goods. It's particularly valuable in foods that contain both water and fat components. Ascorbyl stearate can be made using stearic acid from either plant or animal sources, so its suitability for vegetarians and vegans depends on the source - plant-derived versions are available. Since it's essentially a modified form of vitamin C, it's generally considered a more "natural" antioxidant compared to purely synthetic alternatives. The additive is widely approved for food use and is considered safe, with the added benefit of providing some vitamin C activity along with its antioxidant protection.
