Abstract

塩化ナトリウム,ショ糖およびクエン酸の検知および認知閾値を測定して,加齢および性差の味覚感受性に及ぼす影響について検討した。また,食物嗜好と味覚感受注の関係についても調べた。被験者は65歳以上の男子22名,女子32名,および20歳前後の男子54名,女子54名である。加齢による味覚への影響は顕著に見られた。高齢者は若者に比べ統計的に有意に高い検知閾値を塩化ナトリウムとクエン酸について示し,認知閾値においてはショ糖とクエン酸について示した。クエン酸については性差も認められ,高齢者男子は高齢者女子よりもクエン酸の感受性が低かった。プロビット法により分析したすべての閾値は,ショ糖の検知閾値を除いて,若年者女子,若年者男子,高齢者女子,高齢者男子の順に高くなっていた。塩化ナトリウムに対する感度の低い人は漬物,あるいは塩辛のような塩辛い食物を感度の良い人よりも好んでいた。味覚感受性と食品嗜好の関係についてはほかには認められなかった。

Effects of aging and gender on taste sensitivity were assessed by measuring detection and recognition thresholds of sodium chloride, sucrose, and citric acid. Also, relationship between each taste sensitivity and food preference was examined. The subjects were 22 males and 32 females aged over 65 and 54 males and 54 females aged around 20. A significant overall effect of aging on the taste sensitivity was found. The elderly people showed statistically significant higher detection thresholds for sodium chloride and citric acid and recognition thresholds for sucrose and citric acid than the young ones. There was also a gender effect on the sensitivity for citric acid; the elderly males were less sensitive than the elderly females. All threshold values analyzed by probit method, except in the detection threshold for sucrose, were the following; young females, young males, elderly females and elderly males, arranged in ascending order. It was recognized that the subjects who were less sensitive to sodium chloride, preferred salty foods such as "tsukemono" or "shiokara" more than those with high sensitivity. No relation was found between food preference and taste sensitivity.
