Are There Any Regulations Or Restrictions On The Use Of Sodium Metabisulfite?

Yes, there are regulations and restrictions on the use of sodium metabisulfite. In the United States, it is regulated by the Food and Drug Administration (FDA) as a food additive and is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. However, it must be listed on food labels when used as an ingredient.

Sodium metabisulfite is also used as a preservative in wine and beer production, but there are limitations on its use in some countries. For example, the European Union has set maximum limits for its use in wine production, and it is not allowed to be used in organic wine production.

In addition, sodium metabisulfite can cause allergic reactions in some individuals, and therefore, must be labeled on products containing it. It can also release toxic fumes when exposed to heat or acid, so proper handling and storage are necessary to ensure safety.
