Taste Function in Healthy Taiwanese Adults.

Objective: In this work, our aim was to measure the taste function of healthy Taiwanese adults using 2 commonly used taste tests.

Methods: The taste function of 102 healthy Taiwanese adults was evaluated using the whole-mouth suprathreshold taste test and the taste quad test. In the whole-mouth taste test, 5 concentrations of sweet, bitter, sour, and salty solutions were sipped and swished in the mouth twice in a counterbalanced order. A total of 40 tests were done to give a maximum score of 40 for correct quality identification of tastant solutions. In the taste quad test, the 4 quadrants of the tongue were tested using high concentration drops of sweet, bitter, sour, and salty solutions 6 times. A total of 96 tests were done to give a maximum score of 96 for correct quality identification of tastant solutions.

Results: The score of the whole-mouth taste test ranged from 33 to 40 with a mean of 38.6 for men and from 31 to 40 with a mean of 38.9 for women. The score of the taste quad test ranged from 40 to 91 with a mean of 75 for men and from 38 to 96 with a mean of 78 for women. Sex was shown not to affect the taste function.

Conclusions: Our result showed that sex did not affect the taste function of healthy Taiwanese adults.
