Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Exposure consists of tasting food samples consisting different salt and fat concentrations.
Food samples will be 10 ml of tomato soup.
There will be 20 different fat/salt combinations. Salt concentrations are 0, 1.5, 3, 4.5, and 6% of salt. Fat concentrations will be 0, 10, 20 and 30% of fat. Participants will taste 10 samples per session. There will be 4 sessions, 2 on hedonic ratings (pleasantness, desire) two on intensity ratings.
Participants will also be tested on oral fat taste sensitivity, by using a 3 ascending force choice test. This will be executed in a session before and after the taste sessions of tomato soup.
The durations of the sessions is 1 hour, with at least two days in between.

Subjective ratings of pleasantness by using a 100 mm visual analogue scale.
Timepoint [1] 292986 0
directly after tasting the food sample (1 min)
Secondary outcome [1] 310090 0
Subjective ratings of taste intensity by using a labelled magnitude scale

directly after tasting the food sample (1 min)
Secondary outcome [2] 310305 0
Taste sensitivity to fatty acids
Timepoint [2] 310305 0
Assessed by an ascending forced choice test, duration depends on sensitivity (between 5 and 25 minutes). This outcome is assessed before (baseline) and after the four sessions.

Summary
Brief summary
This study aims to investigate the interactions and effects of salt and fat consumption on
palatability. The objective is to quantify the contributions
of different concentrations of salt and fat in food on subjective liking and wanting in humans classified according to fatty acid taste sensitivity. Fifty
participants, aged 18-45 will participate in the study and will taste food samples with varying salt
and fat contents. Subjective liking and wanting will be assessed in
addition to assessing individuals oral fatty acid sensitivity.
