这项研究考察了两个年龄段的化学感官表现对气味、风味和凉爽程度的影响。进行了两个实验：(1)由训练有素的小组创建感官特征；(2)年轻(n=47，20-35岁)和老年(n=45，65-82岁)受试者对酸奶样品进行享乐性测试，这些受试者也参与了测试他们的化学感觉表现。8个酸奶样品(2x2x2析因设计)用6%或10%的蔗糖、0.2%或0.8%的柠檬香气和0.004%或0.012%的薄荷脑进行调味。年轻受试者在嗅觉、味觉和三叉神经知觉测试中的表现优于老年人。他们在化学感官测试中的表现影响了酸奶的享乐评级，特别是在老年人的情况下。在老年人中，适中的味道受到嗅觉、味觉(甜的、酸的)和三叉神经(薄荷醇)测试的影响。适中的凉爽程度受嗅觉和对甜味的辨别影响。快感受嗅觉和薄荷脑知觉的影响。因此，老年人的化学感觉敏锐度因刺激而丧失，可能会导致对食物的感知扭曲。(C)2003爱思唯尔有限公司。保留所有权利。
This study examined the effects of chemosensory performance of two age groups on ratings of the just-right intensity of odor, flavor and coolness. Two experiments were conducted: (1) creation of a sensory profile by a trained panel and (2) hedonic testing of the yogurt samples by young (n = 47, 20-35 years) and elderly (n = 45, 65-82 years) subjects, who also participated in tests measuring their chemosensory performance. Eight yogurt samples (2x2x2 factorial design) were flavored with 6 or 10% sucrose, 0.2 or 0.8% lemon aroma and 0.004 or 0.012% menthol. Young subjects outperformed elderly in the olfactory, gustatory and trigerninal perception tests. Their performance in the chemosensory tests affected hedonic ratings of yogurts, especially in the case of the elderly. Among the elderly, just-right flavor was affected by the performance in olfactory, gustatory (sweet, sour) and trigerninal (menthol) tests. Just-right coolness was affected by olfactory perception and by identification of sweet taste. Pleasantness was affected by olfactory and menthol perception. Thus, stimulus-specific losses in chemosensory acuity of the elderly may lead to distorted perception of foods. (C) 2003 Elsevier Ltd. All rights reserved.
