Is Sodium Metabisulfite Safe in Food?

Sodium metabisulfite is a common food additive used as a preservative and antioxidant. It helps prevent browning and spoilage in various foods and beverages.

Safety and Regulations

• Regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have approved its use in specific quantities for food preservation.
• Acceptable Daily Intake (ADI) limits are established to ensure consumer safety. Foods usually contain much lower amounts than these limits.
• Products containing sodium metabisulfite in amounts greater than 10 parts per million (ppm) must declare it on the label due to possible sensitivities in some individuals.

Possible Health Concerns

• Some sensitive individuals, especially those with asthma, may experience allergic reactions or respiratory symptoms when consuming foods with sulfites, including sodium metabisulfite.
• Common symptoms may include headaches, hives, or, rarely, more severe reactions.

Conclusion

Sodium metabisulfite is considered safe in food when consumed within regulated limits. However, individuals with sulfite sensitivity or asthma should be cautious and check food labels.
