Malnutrition is a serious problem in the elderly while understanding flavour perception could be a tool for controlling appetite or food choices. To increase our knowledge, we characterised the health and oral physiology (oral volume, swallowing tongue force, number of teeth and salivary flow rate, protein content and antioxidant capacity) of a cohort of 54 community-dwelling French elderly as well as their individual retronasal release of five aroma compounds (2-pentanone, 2-nonanone, 2,3-hexanedione, octanal and linalool) by proton-transfer-reaction mass spectrometry (PTR-MS). In general, large variability across participants was observed in both oral physiological (>40%) and retronasal aroma release (>56%) parameters. Multivariate analyses revealed a relationship between physiological parameters (mostly salivary antioxidant capacity) and retronasal aroma release that explained up to 46% of the variability observed. This study provides new insights to understand retronasal aroma release in the elderly that could contribute to the development of personalised nutrition strategies.
营养不足是老年人的一个严重问题，而了解味觉感知能力可能是控制食欲或食物选择的一种工具。为了增加我们的知识，我们通过质子转移反应质谱（PTR-MS）对 54 名居住在社区的法国老年人的健康和口腔生理学（口腔体积、吞咽舌力、牙齿数量和唾液流率、蛋白质含量和抗氧化能力）以及他们对五种香气化合物（2-戊酮、2-壬酮、2,3-己二酮、辛醛和芳樟醇）的个体反味觉释放进行了特征描述。总的来说，在口腔生理（>40%）和反味觉香气释放（>56%）参数方面，参与者之间存在很大的变异性。多元分析显示，生理参数（主要是唾液抗氧化能力）与反味觉香气释放之间存在关系，这可以解释观察到的变异性的 46%。这项研究提供了对老年人反味觉香气释放的新见解，这可能有助于制定个性化营养策略。
