Sodium metabisulfite
What is Sodium metabisulfite?
Sodium Metabisulfite is a chemical compound commonly used as a preservative. It is created by combining sulfur dioxide with sodium carbonate, leading to a crystalline powder that dissolves in water.
As a preservative, it's effective in preventing the growth of bacteria and fungi in both foods and industrial products. However, it can pose health concerns for sensitive individuals, particularly those with asthma or sulfite sensitivities, as it may trigger allergic reactions or respiratory issues.
When you see Sodium Metabisulfite on a label, it's important to consider the context, especially if you have a known sensitivity to sulfites. It's allowed in many food and cosmetic products but with usage limits imposed by regulatory bodies.
Commonly found in: foods, makeup, food preparation, cleaning products, bottled water
What to watch
- May cause allergic reactions in people with sulfite sensitivity.
- Can trigger asthma symptoms in sensitive individuals.
The FDA regulates its use in food and requires it to be declared on labels due to possible allergic reactions.
Studies show it is effective as a preservative, but there are concerns over asthma and allergy aggravation in sensitive groups.
Sodium Metabisulfite is not derived from animals and is typically considered vegan-friendly.
Scout's take
Sodium metabisulfite is used as a preservative but may cause sensitivities in some individuals and is considered a processed additive.
