Study Overview
Brief Summary
Brief Summary: This study aims to investigate whether protein fortification of beverages causes mouthdrying and mucoadhesion and whether this is influenced by saliva flow.
Detailed Description
To investigate whether whey protein beverages causes mouthdrying and reduces acceptability compared with a control beverage (whey permeate beverage) and to determine whether manipulating salivary flow rates influences mouthdrying.
To determine whether mucoadhesion is a probable cause of mouthdrying.

Arms & Interventions
Protein Beverage
Whey Protein Beverage
Intervention: Liquid Model (Behavioral)
Control Beverage
Whey Permeate Beverage
Intervention: Liquid Model (Behavioral)
Outcomes
Primary Outcomes
Mucoadhesion and Mouthdrying
Time Frame: Saliva collection and mouthdrying scoring throughout visits, 2 days
Following swallowing of different whey beverage samples (whey protein / whey permeate), volunteers will be asked either to rate samples for mouthdrying or to spit their saliva into a tube at specific timepoints (15s \& 60s) with appropriate rest periods. The rating and spitting times will be set within a balanced order protocol.
Secondary Outcomes
- Mouthdrying from whey beverages(1 day (Sampled at study visit one))
- Manipulating saliva flow and mouthdrying from whey beverages(1 day (Sampled at study visit one))
- Saliva collection(1 day (Sampled at study visit two))
