E355

E355 is the European Union's designation for succinic acid, a dicarboxylic acid. It is a naturally occurring compound found in plants and animals and is also produced industrially through chemical synthesis or fermentation. In the context of food additives, E355 functions primarily as an acidity regulator and a firming agent. As an acidity regulator, it helps to control the pH of food products, which can affect their taste, preservation, and stability. Its firming properties can be utilized in processed fruits and vegetables to maintain their texture and prevent them from becoming too soft. Succinic acid and its salts, such as sodium succinate and potassium succinate, are permitted food additives in many regions, including the European Union. The acceptable daily intake (ADI) for succinic acid has been established by regulatory bodies, ensuring its safe use within specified limits. It can be found in a variety of food items, including certain beverages, jams, jellies, and processed vegetables.
