A new extension to the Taste Strips test

Area of Science:

• Sensory science
• Human gustatory perception
• Psychophysics

Background:

• The 'taste strips' test is a validated method for assessing gustatory function.
• Detecting individuals with superior gustatory sensitivity requires refined assessment tools.

Purpose of the Study:

• To extend the 'taste strips' test for identifying subjects with enhanced taste sensitivity.
• To evaluate the efficacy of augmented taste concentrations in discriminating gustatory perception.

Main Methods:

• The study involved 134 participants with normal gustatory function.
• An extended taste strips test (ETS) was developed using lower concentrations of sweet, sour, salty, and bitter stimuli.
• Cluster analysis was employed to group subjects based on their ETS scores.

Main Results:

• The mean ETS was 14.5 ± 3.2, with specific scores for each taste modality.
• The extended test demonstrated no ceiling effect, unlike the original version.
• Cluster analysis revealed three distinct subject groups based on ETS, enabling discrimination of highly sensitive individuals.

Conclusions:

• The extended taste strips test is a valuable tool for detecting individuals with low gustatory thresholds.
• This enhanced method allows for more precise identification of superior gustatory sensitivity.
• The findings support the use of the extended test in clinical and research settings for taste assessment.
