An ingredient once commonly used in citrus-flavored sodas to keep the tangy taste mixed thoroughly through the beverage could finally be banned for good across the US.
The FDA proposed in November to revoke the registration of a modified vegetable oil known as BVO in the wake of recent toxicology studies that make it difficult to support its ongoing use.
“The proposed action is an example of how the agency monitors emerging evidence and, as needed, conducts scientific research to investigate safety related questions, and takes regulatory action when the science does not support the continued safe use of additives in foods,” James Jones, FDA deputy commissioner for human foods, explained when announcing the proposal.
BVO, or brominated vegetable oil, has been used as an emulsifying agent since the 1930s to ensure citrus flavoring agents don’t float to the top of sodas. Sticking a dozen bromine atoms to a triglyceride creates a dense oil that floats evenly throughout water when mixed with less dense fats.
Yet that’s not BVO’s only trick. Animal studies have strongly implied the compound can slowly build up in our fat tissues. With bromine’s potential ability to prevent iodine from doing its all-important work inside the thyroid, health authorities around the world have been suspicious of the emulsifier’s risks for decades.
In fact, BVO is already banned in many countries, including India, Japan, and nations of the European Union, and was outlawed in the state of California in October 2022 with legislation due to take effect in 2027.
