PTC Test Paper


Use these PTC paper strips for a heredity taste test. Find out if you can detect bitterness. If so, you might be a super taster!

For years, educators have used PTC* paper when they teach about genetics and heredity.  Why? On average, 75% of people can taste PTC, while 25% cannot. The majority of the people who can taste PTC (nicknamed “tasters”) report that to them, PTC tastes extremely bitter while other tasters report only a mild bitter taste.  The other 25% of the population (“non-tasters”) can not taste PTC at all.


Despite its taste (to some, that is), PTC is a harmless chemical.  This vial contains 100 pieces of PTC paper—enough to perform many tests.
