Esters of fatty acids and ascorbic acid (E304) – what is it?
Esters of fatty acids and ascorbic acid, also known as E304, are synthetic chemical compounds used as food additives. They are formed by esterifying ascorbic acid (vitamin C) with fatty acids. E304 is widely used in the food industry for its antioxidant properties and its ability to extend the shelf life of food products by preventing the rancidity of fats.
This food additive can come in various forms, including ascorbyl palmitate and ascorbyl stearate, depending on the type of fatty acid used. It is valued for its versatility and effectiveness in protecting the quality and taste of food products.
Properties of E304
Fatty acid esters and ascorbic acid are known for their powerful antioxidant properties, which help protect food products from oxidation. As a result, they can effectively extend the shelf life of products by preventing processes that lead to food spoilage, such as fat rancidity. E304 is also fat-soluble, making it easier to use in products containing fats and oils.
Uses of E304
Esters of fatty acids and ascorbic acid are widely used in a variety of food products, including snacks, bakery products, beverages, spreads, dairy products and prepared meals. E304 is also added to foods packaged in a protective atmosphere to prevent oxidation and preserve freshness.
Where to buy E304?
E304 can be purchased both in specialty stores with raw materials for the food industry and online. It is available to food manufacturers and small food businesses that want to improve the shelf life and quality of their products. However, it is important to keep in mind the need for proper storage conditions for the substance to preserve its antioxidant properties.
E304 and its functions in food
The additive E304 has several key functions in food, including acting as an antioxidant that helps preserve the freshness and color of food products. By preventing oxidation, fatty acid esters and ascorbic acid effectively extend the shelf life of foods and help maintain their nutritional and organoleptic values. This is especially important in products containing fat, where E304 prevents rancidity and maintains the desired flavor and aroma of products.
