Therefore, in the selection of panelists for sensory evaluation purposes the first step is to establish the limits of their sensory capacities by determining their perception thresholds for basic tastes, flavor, and odor recognition. checkpoint ppc tools login

"WebOne of the earliest characteristics of human sensory function to be measured was the absolute threshold. The absolute or detection threshold was seen as an energy level below which no sensation would be produced by a stimulus and above which a sensation would reach consciousness. The concept of threshold was central to Fechner’s psychophysics. " - Sensory threshold psychology
