NEW YORK — Coca-Cola is dropping a controversial ingredient from its Powerade sports drink, after a similar move by PepsiCo’s Gatorade last year.
The ingredient, brominated vegetable oil, had been the target of a petition by a Mississippi teen, who questioned why it was being used in a drink marketed toward health-conscious athletes. The petition on Change.org noted that the ingredient is linked to a flame retardant and is not approved for use in Japan or the European Union.
In response to customer feedback, PepsiCo said last year it would drop the ingredient from Gatorade. At the time, Coca-Cola declined to say whether it would remove the ingredient from the two flavors of Powerade that contain it as well.
But bottles of Powerade in fruit punch and strawberry lemonade flavors being sold in the areas of Detroit, Omaha, New York, and Washington, D.C., no longer list the ingredient. Some bottles still list it, however, suggesting Coca-Cola Co. may have started phasing it out recently.
A representative for the Atlanta-based company confirmed Sunday that its Powerade brands are ‘‘BVO-free.’’ But no details were immediately available on when the change would be complete or how the drinks were reformulated.
Powerade’s website still lists brominated vegetable oil as an ingredient for its fruit punch and strawberry lemonade flavors.
The Food and Drug Administration says brominated vegetable oil is used as a stabilizer for flavoring oils in fruit-flavored drinks. Coca-Cola has said in the past that it uses it to ‘‘improve stability and prevent certain ingredients from separating.’’
The decision by Coca-Cola to remove brominated vegetable oil from Powerade is just the latest evidence that food makers are coming under pressure for the ingredients they use. While companies stand by the safety of their products, some are making changes in response to the movement toward foods that people believe are natural.
Likewise, brominated vegetable oil can also be found in several other drinks.
But the Mississippi teen, Sarah Kavanagh, said she targeted Gatorade and Powerade in petitions because they’re designed for athletes, who are likely more concerned about what they’re putting into their bodies. Her Powerade petition had more than 59,000 online supporters while the Gatorade one had more than 200,000.
