What are the ingredients in Mentos mints?

Mentos mints contain a variety of ingredients, including sugar, hydrogenated coconut oil, rice starch, gum arabic, gellan gum, carnauba wax and beeswax. Other Mentos products, including those with different flavors, may have slight variants apart from these ingredients.

One Mentos mint contains only 10 calories and 2 grams of sugar.

The ingredients in Mentos cause it to fizz and have an explosive reaction when combined with the ingredients in Diet Coke. This is partly due to the gum arabic in Mentos, which reduces surface tension in Diet Coke. It is a common science project to drop Mentos into Diet Coke and speculate on the cause of the explosive reaction.
