NEW YORK, N.Y. - Coca-Cola and PepsiCo said Monday they're working to remove a controversial ingredient from all their drinks, including Mountain Dew, Fanta and Powerade.

The ingredient, called brominated vegetable oil, had been the target of petitions on by a Mississippi teenager who wanted it out of PepsiCo's Gatorade and Coca-Cola's Powerade. In her petitions, Sarah Kavanagh noted that the ingredient has been patented as a flame retardant and isn't approved for use in Japan and the European Union.

Coca-Cola and PepsiCo have stood by the safety of the ingredient, which is used to distribute flavours more evenly in fruit-flavoured drinks. But their decisions reflect the pressure companies are facing as people pay closer attention to ingredient labels and try to stick to diets they feel are natural. Several major food makers have recently changed their recipes to remove chemicals or dyes that people find objectionable.

While food companies stress that the ingredients meet regulatory requirements, their decisions reflect how marketing a product as "natural" has become priority and a competitive advantage.

PepsiCo had said last year that it would remove brominated vegetable oil from Gatorade. On Monday, the company said it has since been working to remove it from the rest of its products. PepsiCo also uses BVO in its Mountain Dew and Amp energy drinks.

The company, based in Purchase, New York, didn't provide a timeline for when it expects the removal to be complete.

Earlier on Monday, Coca-Cola had also said that it's removing the ingredient from all its drinks to be consistent in the ingredients it uses around the world. In addition to Powerade, Coca-Cola uses BVO in some flavours of Fanta, Fresca and several citrus-flavoured fountain drinks. The company said BVO should be phased out in the U.S. by the end of the year.

Coca-Cola said it would instead use sucrose acetate isobutyrate, which it noted has been used in drinks for more than 14 years, and glycerol ester of rosin, which it said is commonly found in chewing gum and drinks.

A Coca-Cola spokesman, Josh Gold, noted that BVO isn't used in many other countries, but said it would be phased out in Canada and Latin America as well.

The Center for Science in the Public Interest, a health advocacy group, notes that the Food and Drug Administration permitted the use of BVO on an interim basis in 1970 pending additional study. Decades later, the group notes that BVO is still on the interim list.

Kavanagh, the Mississippi 17-year-old, had been planning on launching another petition on asking PepsiCo to remove BVO from all its drinks. She wasn't immediately available for comment late Monday. Earlier in the day, however, she said, "It's really good to know that companies, especially big companies, are listening to consumers."

  • Coke Contains Alcohol
    SOMEWHAT TRUE: Coca-Cola is officially a non-alcoholic beverage. In fact, it was created specifically to be a soft drink during the temperance movement, a political campaign advocating abstinence from alcohol. However, research by the National Institute of Consumption in Paris revealed that there is 0.001 per cent per litre in many popular soda brands, including Coca-Cola. The Coca-Cola website maintains that traces of alcohol can occur naturally in many beverages and such low levels are considered acceptable by governments.
  • Coke Contains Pork
    FALSE: There have been several rumours that Coke contains ‘pork extract.’ The company’s website debunks this by saying the drink doesn’t have any animal derivatives and is vegan-friendly. It's possible this rumour started as a result of another myth, that pouring Coke on pork can make "worms" come out of it, later debunked by Snopes.
  • Coke + MSG = Aphrodisiac
    FALSE: There are rumours that Coke added MSG to their secret recipe because it creates an aphrodisiac. Coca-Cola holds firm that the flavour enhancer is not in the drink, and also that Coke is in no way an aphrodisiac. Smell expert Dr. Alan Hirsch, however, has postulated that thanks to Coke's role at certain points in our lives, the scent and smell might evoke feelings of comfort, or alternatively, alertness, according to YourTango.
  • Coke Contains Bug Dye
    FALSE: It’s widely believed that Coke contains a red food dye made from cochineal beetles. This isn’t true, according to the company. However, bug dye is commonly used in foods such as meat, jam and baked goods in general, often referred to as Cochineal, Cochineal Extract, so look out for that.
  • Coca-Cola’s Name Is Derived From Its Use Of Cocaine
    TRUE: Coke no longer has any cocaine. It’s uncertain how much, but there was a significant amount in the drink until 1903, reports Live Science, and the drink contained some of the illegal drug in its recipe until 1929.
  • Coke Has Acids That Will Dissolve Your Teeth
    SOMEWHAT TRUE: Coke does contain citric and phosphoric acid, which can wear on teeth's enamel in the long term. These acids are common in many food and drinks, like orange juice, but in low levels so that they don’t put a strain on our digestive systems.
  • Coke Can Help You Clean Your House
    SOMEWHAT TRUE: It’s also said that these acids make the drink a useful household cleaning product. While it contains carbonic acid, which can help in removing stains, according to Snopes, it’s a weak solution. Water is generally better since it doesn’t leave behind a sticky sugary residue.
