Sensory Analysis

5. Thresholds

1. Threshold

Lowest concentration or intensity at which a change compared to another sample is perceived, which means: the type of change is not yet recognized, only a difference has been noticed.

2. Detection Threshold

Lowest concentration or intensity at which a characteristic or substance can be identified (e.g. sweet).

3. Difference Threshold

Lowest concentration or intensity that is necessary to perceive a difference between two stimuli.

4. Saturation Threshold

Concentration or intensity, above which a further increase does not produce a stronger impression. This is reached as soon as all receptors are occupied.
