Trace amounts of alcohol can be found in popular soft drinks including Coca-Cola and Pepsi, according to new findings by the National Institute of Consumption in Paris.
The research, published in the French magazine 60 Million Consumers, found small amounts of alcohol measuring around 0.001 percent per liter in 19 popular sodas around the world. Generic supermarket brands, however, were alcohol-free.
Business Insider also reports that another chemical present in Coke, 4 methylimidizole (4-MI), is considered a carcinogen by the Center for Science in Public Interest.
The publication has more background on why the alcohol was detected:
Coca-Cola France’s scientific director Michel Pepin told Channels TV that it is possible “alcohol traces come from the process of making our drink according to its secret recipe,” perhaps due to natural fruit fermenting.
While the amount of alcohol found is negligible, the revelation may anger thousands of Muslims, whose religion prohibits them from drinking alcohol.
Trace levels of alcohol can occur naturally in many foods and beverages. Governments and religious organizations have recognized that such minute levels are considered acceptable in nonalcoholic foods and beverages.
Coca-Cola has no plans to change the recipes for any of its products.
CORRECTION: A previous version of this article stated that Coca-Cola will alter the recipes for sodas sold in the U.S. It has been updated to reflect that the company will not be doing so.
