About

This study aims to investigate whether protein fortification of foods and beverages causes mouthdrying and mucoadhesion and whether this is influenced by age and saliva flow.

Full description

1. To investigate, by using protein fortified foods and beverages, whether mucoadhesion to the oral cavity is greater for older adults compared to younger adults and determine whether it is related to salivary flow rate.
2. To determine whether protein fortification of foods and beverages causes mouthdrying and whether perception and acceptance are influenced by age and individual differences in saliva flow.

These aims will be investigated using two different models: a liquid model using whey protein and a solid model using protein fortified biscuits and cakes.
