Sodium benzoate

Ingredient Type: Preservative
Additive Number: 211

Sodium benzoate is a common food preservative that is often added to protein powders to help extend their shelf life. It is a salt of benzoic acid and is typically used in concentrations ranging from 0.05% to 0.1%.

As a preservative, sodium benzoate works by inhibiting the growth of bacteria and fungi, which can help prevent spoilage and ensure that the protein powder remains safe for consumption over an extended period of time.

Sodium benzoate is generally considered safe for consumption by regulatory agencies around the world, including the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, there have been some concerns raised about the safety of sodium benzoate when it is combined with certain other ingredients, such as vitamin C, as this can result in the formation of benzene, a potentially carcinogenic substance.

Overall, sodium benzoate is generally considered safe when used in the recommended amounts. However, individuals who are concerned about the potential risks associated with this preservative may wish to seek out protein powders that do not contain sodium benzoate or other synthetic preservatives.
