📰Recent developmentsRegulator assessment checked 25 Sep 2026
  • JECFA’s specification for erythorbic acid was prepared at its 37th meeting and revised for metals and arsenic specifications at its 61st meeting. The current sources checked do not identify a newer EFSA numerical ADI for E315.
  • JECFA established an ADI not specified for erythorbic acid. That conclusion applies to the specified uses and does not replace the food-category conditions in local regulations.
  • An ADI or “not specified” conclusion is a population risk-assessment reference, not a statement that a particular food is unsafe.

This section is checked periodically rather than continuously — confirm the current primary source before relying on a regulatory detail.
