E315 is an additive approved by the EU (European Union). It is used as a synthetic antioxidant in food and drink products.
The common name for E315 is erythorbic acid. It may also be referred to as araboascorbic acid or saccharosonic acid.
E315 is a synthetic isomer* of E300 (vitamin C),
and is produced from sucrose. E315 has a much lower vitamin activity than E300.
*Isomers are compounds that have the same molecular formula, but a differing structural formulea, so a molecule of E315 contains the same types and proportions of atoms as a molecule of vitamin C, but they are arranged differently.
