These coke drinks are not doing well

The color of the drink is a problem for the testers: the typical brown of a Coca-Cola almost always comes from the caramel coloring. He brought the pollutant 4-methylimidazole (4-MEI) with him. This substance is considered to be a potential carcinogen.

The fact that Red Bull Cola exceeds the limit for alcohol is "a flagrant violation of the law", the Stiftung Warentest says in its article. From his point of view, this indicates insufficient quality control. For pregnant women and children, the amount of three grams per liter is safe. Even for dry alcoholics, there is little risk of relapse. So much alcohol can be in the fruit juice.

The foundation also discovered the secret of cola through laboratory analysis. The spectra of the aromas were determined: all had a similar taste – with aromas of citrus, cinnamon, and still some with nutmeg. Bitter caffeine also contributes to the taste of cola. It must be labeled as an aroma because it comes mainly from synthetic manufacturing, as explained by suppliers to testers.
