Sodium Sulfite (E221) – Overview, Uses, Side Effects & More

Additive Summary Sodium Sulfite (E221)
Essence Sodium Sulfite or E221 is a white powder (inorganic, non-stable) typically used as a synthetic preservative to avoid food spoilage and has a faint Sulfur Dioxide smell.
Names Sodium Sulphite, Sodium Salt of Sulphurous Acid, Disodium Sulfite, CAS 7757-83-7, E221, Sodium Sulfite, and others.
Sourcing  Commercially, it is typically created out of Sulfur Dioxide (E220).
Manufacturing There are various ways to create it. Arguably, the most straightforward one is by treating the sourcing ingredient with Sodium Carbonate solution. But it can also be made by mixing together Sodium Hydroxide and the sourcing ingredient. And more ways do exist.
Application Preservative (synthetic, water-soluble) and antioxidant.
Acceptable Daily Intake 0.7 milligrams for every kilogram of body weight is said to be the level that won’t cause any health risks. But I would beg otherwise, especially considering that people typically consume way more than this amount (when it comes to sulfites in general).
Side Effects It essentially offers all the side effects that Sulfur Dioxide (E220) does. It can reduce vitamin contents, and cause diarrhea, vomiting, headaches, asthma, and asthma-related detrimental effects.
