The invention discloses a method, system and device for distinguishing special concentration of sensory evaluators. According to the method, concentration distinguishing is organically combined with evaluation of excellent, good and poor sorting abilities, that is to say, sensory evaluators with high sensitivity and poor concentration can be found in a group with the excellent sorting ability, sensory evaluators with moderate sensitivity and high concentration can be found in a group with the good sorting ability, and sensory evaluators with passable sensitivity and high concentration can be found in a group with the poor sorting ability. By adopting the system for distinguishing the special concentration of the sensory evaluators, the sensory evaluators with the special concentration canbe found, and favorable support is provided for the reliability of sorting results.
