Investigating Consumers Perception and Acceptance of Whey Beverages

March 11, 2021 updated by: Lisa Methven, University of Reading
Brief Summary: This study aims to investigate whether protein fortification of beverages causes mouthdrying and mucoadhesion and whether this is influenced by saliva flow.

Study Overview

Status

Completed

Intervention / Treatment

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 and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Protein Beverage
Whey Protein Beverage

To study the perception of whey beverages using sensory methods (rating drying as well as discrimination tests "which is the stronger in drying")

Measuring mucoadhesion via protein content remaining in saliva following swallowing of whey protein and whey permeate beverages.

Experimental: Control Beverage
Whey Permeate Beverage

To study the perception of whey beverages using sensory methods (rating drying as well as discrimination tests "which is the stronger in drying")

Measuring mucoadhesion via protein content remaining in saliva following swallowing of whey protein and whey permeate beverages.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Saliva collection and mouthdrying scoring throughout visits, 2 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mouthdrying from whey beverages
Time Frame: 1 day (Sampled at study visit one)
Perceived mouth drying from whey beverages (whey permeate / whey protein) using data from sensory methods (rating drying as well as discrimination tests "which is the stronger in drying"). Scale for scoring is the gLMS scale (general linear magnitude scale); higher value is worse outcome.
1 day (Sampled at study visit one)
Manipulating saliva flow and mouthdrying from whey beverages
Time Frame: 1 day (Sampled at study visit one)
Volunteers will be asked to manipulate their saliva flow and consume whey beverages (whey permeate / whey protein) and score perceived mouth drying (data will be collected from sensory methods (rating drying as well as discrimination tests "which is the stronger in drying")
1 day (Sampled at study visit one)
Saliva collection
Time Frame: 1 day (Sampled at study visit two)
Salivary flow rates from unstimulated and stimulated saliva samples.
1 day (Sampled at study visit two)

IPD Plan Description

No personal identification data will be shared. The study is not under an obligation to share data, however it is possible that some of the individual (unliked / non identifiable) data will be useful in a meta analysis and, hence sharing individual participant data (IPD) will be considered.
