Investigating the Influence of Age and Saliva Flow on the Perception of Protein Fortified Foods and Beverages
調査の概要
詳細な説明
To investigate whether whey protein beverages cause mouthdrying in older adults and if perception and acceptance are influenced by repeated consumption, age and individual differences in saliva flow.
To investigate whether protein fortification of cupcakes causes mouthdrying and if perception and acceptance are influenced by repeated consumption, age and individual differences in saliva flow in a home environment.
To investigate whether mucoadhesion is present within different food models, if sensitivity to mucoadhesion increases with age and to determine if a reduced salivary flow results in strengthened mucoadhesion.

介入・治療 |
|---|---|
|
実験的:Solid Model
Whey Permeate Lemon Cupcake and Protein Fortified Lemon Cupcake
|
Cupcakes will be used, with the amount of protein varied to study the effect on perception of the products (using sensory methods rating drying and discrimination tests 'which is the stronger in drying').
Measuring mucoadhesion via protein content remaining in saliva samples following consumption of cupcakes.
|
|
実験的:Liquid Model
Whey Protein Beverage
|
To study the perception of whey protein beverages using repeated consumption sensory methods (e.g.
rating mouthdrying over repeated sips of the drink).
