Whey Protein Derived Mouthdrying Found to Relate Directly to Retention Post Consumption but Not to Induced Differences in Salivary Flow Rate

Whey protein is fortified into beverages to provide functional benefits, however, these are considered mouthdrying. To date whey derived mouthdrying has not been quantified using a ‘physical measure’ in parallel with rated perception. Saliva flow could also relate mouthdrying, however this previously tested as an intervention. Accordingly, volunteers (n = 40) different and the sensory profile was evaluated by trained panel 10). Volunteers combined collection of saliva samples post beverage consumption measure retention oral cavity. modulate rate, both chewed on parafilm (to increase flow) used cotton wool remove saliva) before tasting rating Both (WPB) significantly more than control (whey permeate). The higher from coincided concentration WPB consumption, supporting mucoadhesion mechanism. Modulating did lead any difference future work would be beneficial evaluate further influence natural variation salivary rate.
