The Bitter Truth about PTC and Broccoli

Overview

Objectives/Goals My objective was to find out if people who can taste PTC strongly would be more likely to dislike broccoli than those who cannot taste it at all. Methods/Materials First 122 subjects, between the ages of 10 and 45, were tested with a taste paper called PTC. They were then given surveys inquiring about their sex,ability to taste PTC, and preference in certain vegetables, including broccoli. The surveys were then tallies and the results were determined. Results There is no corrolation between the ability to taste PTC and the prefrence of broccoli. Ten percent of non tasters disliked broccoli while 20% of the very strong and strong tasters disliked it. This differece is not significant in supporting or rejectiing my hypothesis. Conclusions/Discussion My conclusion is that the data is not sufficient to support or reject my hypothesis. I believe that other factors, such as personal taste, may contribute to the prefrence of broccoli more than the ability to taste PTC. Even though broccoli tastes bitter to many people, it appears that this does not necesarily mean that these people will also taste the bitter PTC.
