BVO's Primary Use: A Stabilizing Emulsifier
Brominated vegetable oil (BVO) was primarily used as a food additive acting as an emulsifier in fruit-flavored beverages, especially those with citrus oils. Its function was to keep flavoring oils from separating from the liquid, preventing an uneven appearance. Brominating the oil helped match its density to water, ensuring even flavor distribution and a consistent cloudy look.
Historical Examples of BVO-Containing Products
Before public pressure and health concerns prompted companies to remove it, BVO was present in many soft drinks and sports drinks. While major brands reformulated years ago, some smaller and regional brands continued its use. Historically, products like Mountain Dew, Gatorade, Fanta Orange, certain store-brand sodas, and Sun Drop contained BVO.
The Role of Regulation and Reformulation
BVO's journey to a banned substance reflects evolving food safety standards. The FDA initially granted BVO provisional use in the late 1960s but concerns over health risks, particularly thyroid impact, remained. International bans in the EU (2008) and Japan (2010) preceded the US action. The FDA's 2024 ban followed recent animal studies confirming potential adverse effects.
Comparison of BVO with Common Alternatives
Manufacturers have transitioned to approved alternatives for emulsification. Here is a comparison:
| Feature | Brominated Vegetable Oil (BVO) | Sucrose Acetate Isobutyrate (SAIB) | Glycerol Ester of Wood Rosin (Ester Gum) |
|---|---|---|---|
| Function | Stabilizing emulsifier for flavor oils in beverages. | Stabilizing emulsifier for flavor oils in beverages. | Stabilizing emulsifier for flavor oils in beverages. |
| Health & Safety | Associated with potential health risks, banned by the FDA in 2024. | Considered safe by regulatory bodies and widely used. | Considered safe by regulatory bodies and widely used. |
| Regulatory Status | Banned in the U.S. and many other countries. | Permitted for use in food in the U.S. and EU. | Permitted for use in food in the U.S. and EU. |
| Global Usage | Historically used in North America, banned in EU and Japan. | Widely used worldwide as a BVO replacement. | Widely used worldwide as a BVO replacement. |
How to Avoid Additives in Your Diet
With the BVO ban in effect, consumers don't need to worry about this specific additive in U.S. products. However, those wishing to minimize synthetic additive intake can:
- Read the Label: Check ingredients; BVO was previously listed as "brominated vegetable oil" or "brominated soybean oil".
- Choose Water and Natural Juices: These are simple additive-free beverage options.
- Make Your Own: Control ingredients by preparing flavored drinks at home.
- Look for Alternatives: Choose products marketed as free from artificial ingredients.
Conclusion
The question of what foods contain brominated vegetable oil is now largely historical due to the 2024 U.S. FDA ban. Historically, BVO was primarily found in citrus-flavored beverages like sodas and sports drinks to stabilize flavors. Manufacturers have transitioned to safer alternatives in response to evolving safety standards. Consumers can stay informed by checking labels and choosing whole-food alternatives.

A Quick Summary of BVO
- BVO was an emulsifier: Used to stabilize citrus flavor oils in beverages.
- Found primarily in drinks: Historically present in citrus-flavored sodas, sports drinks, and energy drinks.
- FDA banned it in 2024: Due to potential health risks, particularly to the thyroid.
- International bans preceded the US: Many countries banned BVO years ago.
- Safer alternatives exist: Manufacturers use approved alternatives like SAIB and ester gum.
- Check older products: Some older or regional products might still contain BVO until compliance is complete.
- Shift towards cleaner ingredients: Reflects a trend towards removing potentially harmful additives.
Frequently Asked Questions about BVO
1. What is brominated vegetable oil (BVO)? BVO is a food additive that stabilizes citrus flavorings in beverages by preventing separation.
2. Is BVO still used in any foods in the US? No, the FDA banned BVO in July 2024. While older products may still be available during a compliance period, new products sold in the US should not contain BVO.
3. Which types of drinks historically contained BVO? It was most common in citrus-flavored sodas, sports drinks, and energy drinks, including brands like Mountain Dew, Gatorade, and some store brands.
4. Why was BVO banned by the FDA? The ban was based on animal studies indicating potential adverse health effects, particularly on the thyroid gland, and the concern of bromine accumulation in the body.
5. Are other countries also banning BVO? Yes, BVO was banned in many countries before the US, including the European Union (2008), Japan (2010), and Canada (2024).
6. What are manufacturers using instead of BVO? Approved alternatives like sucrose acetate isobutyrate (SAIB), glycerol ester of wood rosin (ester gum), and other natural gums and modified starches are used.
7. How can consumers avoid BVO and other additives? Read product labels, choose whole-food drinks like water or natural juices, and look for products claiming to be free from artificial additives.
