A comparison of the ability of 8-9-year-old children and adults to detect taste stimuli.

Conflicting data exist in the literature regarding the maturity of the human sense of taste during childhood and if gender influences gustatory development. To investigate these 2 questions, taste detection thresholds for the 4 common tastants sucrose, sodium chloride, citric acid, and caffeine were established for 61 young adults and 68 children aged 8-9 years old, using a paired-comparison forced-choice procedure. No significant differences were found between the mean thresholds of women and men, or between those of female children and adults. In contrast, male children had significantly higher thresholds for all 4 tastants than adult females, for all tastants except caffeine than adult men, and for sucrose and sodium chloride than female children. It is concluded that the taste sensitivity of 8-9-year-old males, although well developed, has not fully matured, and that taste sensitivity is not affected by gender in young adults.
