Salivary properties involved in astringency sensitivity in human differ as a function of age

2022

Astringency is an important sensory characteristic of foods and beverages containing polyphenols. However, astringency perception in elderly people is not documented. Current hypothesis on astringency mechanism involved aggregation of the mucosal pellicle by tannins and its protective role by salivary proteins in particular proline rich-proteins (PRPs). The aim of the present work was to evaluate sensitivity to astringency in function of age and saliva (flow and composition). Fifty-four panelists including (30 elderlies and 24 young) participated in this study. Astringency was evaluated by 2-Alternative Forced Choice procedure. For salivary PRPs, a western blot methodology was set up to eva…
