Sodium erythorbate

Sodium erythorbate is the sodium salt of erythorbic acid (E315), used primarily as an antioxidant and curing accelerator in processed meats. It is one of the most widely used antioxidants in the meat industry, where it accelerates colour development during curing by reducing nitrite to nitric oxide more rapidly, and inhibits nitrosamine formation — the compounds that are the principal cancer-risk mechanism in cured meats. In this respect, E316 may partially offset one adverse effect associated with sodium nitrite (E250) when the two are used together.

JECFA's ADI is "not specified," consistent with its metabolic pathway as a harmless erythorbate salt. Evaluated in 1990, the compound presents no toxicological concern at food additive concentrations. Its role in limiting residual nitrite levels is considered a net safety benefit in the cured meat context.

Sodium erythorbate is approved in the EU, US (GRAS), UK, Australia, and globally. It is ubiquitous in cured and processed meats — hot dogs, bacon, ham, sausages, and deli meats routinely list it on ingredient labels. Its presence in a product is not itself a safety concern. However, consumers choosing to limit processed meat consumption for broader health reasons should note that E316 does not offset all risks associated with high processed meat intake, given the IARC Group 1 classification of processed meat overall.
