A taster is a person, by means of a human genotype, who is able to taste phenylthiocarbamide (PTC) and its derivative 6-n-propylthiouracil (PROP).
[1] PTC tastes bitter to many people (tasters) but is tasteless to others (non-tasters).
[2] About 70% of Caucasians from North America and Western Europe are tasters.
Worldwide, fewer Black and Asian persons are non-tasters, and about 50% of indigenous persons from India are non-tasters.
