Thiourea test paper test for the genetic capability to detect Thiourea. For other taste tests, see our PTC and Sodium Benzoate test papers. 1.Remove a Thiourea test paper from the vial. 2.Place the test strip on your tongue and it will either taste bitter or it won’t taste like anything at all.

The Control Paper does not contain any added chemicals, and is simply designed to act as the control in taste test experiments. 1.Remove one strip of Control Paper from the vial. 2.Stick out your tongue and place the strip on your tongue. 3.The strip is tasteless, and thus should not stimulate a reaction.
