对71名年龄在20-88岁的成年人进行了蔗糖味觉检测。强制选择，跟踪程序被用来消除受试者的反应偏差，并在所有刺激之间包括漂洗。与年龄相关的敏感度显著下降。敏感度的损失不是很大，老年人的阈值变化很大。据报道，一项关于盐味敏锐度的类似研究表明，随着年龄的增长，阈值略有增加，但在统计学上具有显著意义。观察到与年龄相关的味觉敏感度差异并不大，这与成年哺乳动物味蕾细胞不断被替换的生物学信息一致。
Sucrose taste detection thresholds were measured in 71 adults [humans] aged 20-88 yr. A forced-choice, tracking procedure was used to eliminate subject response bias and rinses were included between all stimuli. A significant age-related decrease in sensitivity was observed. The loss of sensitivity was not great and elderly people had highly variable thresholds. A similar study on salt taste acuity was reported which demonstrated a small, but statistically significant threshold increment with age. The observation that age-related differences in taste sensitivity are not large is consistent with biological information that taste bud cells are continuously replaced in adult mammals.
