Abstract
The relationship between the bitter food preference and taste sensitivity to PROP (6-n-propylthiouracil) was examined in 108 university students. A taste test indicated that the preference for a straight coffee solution and caffeine fell with higher taste sensitivity to PROP; however, the preference for coffee with added milk and sugar, and for powdered tea (maccha) was not correlated with the taste sensitivity to PROP. The answers to a questionnaire showed that the preference for coffee and beer was not correlated with the taste sensitivity to PROP. These results suggest that the taste sensitivity to PROP may be related to bitter food preferences, but that the correlation may not be strong.
