Preservatives are not permitted to be used in canned food products, according to regulations of the Food and Drug Administration (FDA). Nastaran Mohammadi, head of Monitoring and Evaluation of Plant-Based Food Products at the FDA, dismissed reports on social media that canned foods in Iran contain a harmful preservative that can lead to iron deficiency and anemia in consumers, IRNA reported. Canning is a method of preserving food in which the food contents are processed and sealed in an airtight container. “But no preservatives are used,” he said.
