Distribution of non-tasters for phenylthiocarbamide and high sensitivity to quinine hydrochloride of the non-tasters in Japanese.
The percentage of non-tasters for phenylthiocarbamide in 915 Japanese students was 9.4%. The thresholds of the edge and back of the tongue to quinine hydrochloride were significantly smaller in the non-tasters than in the tasters. The thresholds of any tongue portions to NaCl, acetic acid or sucrose did not differ between the tasters and the non-tasters.
