Mint-flavored gum lasts longer than fruit-flavored gum, as determined by tests reported by Education.com. The project was carried out by school children using three unnamed packs of fruit-flavored gum and three unnamed packs of mint-flavored gum.
In the project, six elementary school volunteers recorded in a notebook how long the flavor lasted in each type of gum. The reason mint-flavored lasts longer than fruit-flavored gum has to do with the chemicals that are added to the gum to give it artificial flavor, according to Education.com. The chemicals that make the mint flavor leave a lasting taste not only in the mouth but on the taste buds. This gives the impression that there is still flavor in the gum long after the flavor has worn out.
