E301

E301 is the European food additive code for sodium ascorbate, the sodium salt of ascorbic acid (vitamin C). It is used as a food additive with antioxidant properties and, in some cases, as an acidity regulator. As an antioxidant, sodium ascorbate scavenges free radicals, helps prevent oxidation of fats and oils, delays browning, and can regenerate other antioxidants in a product. It also serves as a source of vitamin C in fortified foods.

In practice, E301 is used across a wide range of products, including beverages, fruit juices, dairy products, processed meats, canned vegetables, and bakery fillings. It helps preserve color, maintain flavor, and extend shelf life. Its water solubility can offer formulation advantages, though it remains susceptible to degradation under heat, metal ions, and prolonged storage, depending on conditions.

Regulatory status: In the European Union, E301 is the assigned code for sodium ascorbate and is permitted as a food additive within defined purity criteria and usage levels under EU food safety regulations. It is listed in many other national and regional catalogs as well.

Safety and dietary notes: As a vitamin C source, it contributes to daily intake. As a sodium salt, it adds sodium to the diet, which may be a consideration for individuals on sodium-restricted regimens. High doses can cause gastrointestinal discomfort in some people. It is generally regarded as safe when used within regulatory limits.
