- Brief summaryRationale:
Currently several fat and sugar-reducing strategies are used to decrease the energy density of foods, some are accepted by the consumer and some are not. We hypothesize that the successful strategies have specific effects on foods that are able to mimic certain taste and texture related sensations. However, no data is available on specific oral processing movements or patterns that are used to perceive the taste and texture of products. Knowledge of these movements/patterns might bring the development of fat and sugar-reducing strategies to a higher level.

Objective:
The primary objective of this study is to identify specific oral processing movements and/or patterns that occur during consumption of (semi-)liquid foods, with respect to taste and texture related properties (e.g. taste intensity and viscosity), and the sensory perception thereof (e.g. rated taste intensity and thickness).

Study population:
The study population will consist of 30 healthy, normal weight volunteers, aged between 18 and 50 y.

Study design:
The experiment is observational. Within the sessions we make within person comparisons between products and rated attributes of a series of foods. Each subject will participate in three sessions spaced one week apart.

Study outcomes:
Oral processing will be measured with different techniques. Tongue and jaw movements will be measured by means of articulography (EMA); sensors will be placed on the face and on the tongue to monitor spatial and temporal movement. Additionally, electromyography (EMG) will assess muscle contraction and muscle force needed to process the foods.
