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.
