The present invention relates to a method for quantitatively measuring sensory perception of food using a metacognitive confidence magnitude scale on the basis of the detection theory. Specifically, in order to measure conceptual food quality characteristics of a consumer, the method can, differently from measuring methods of the existing detection theories, measure the intensity of a signal without measuring background noise, determine the degree of sensory stimulus using a single specimen. Moreover, the method does not require a standard inspection object for sensory evaluation and thus can simply and exactly measure the sensory perception of a consumer. Also, the method can simply and exactly measure whether a consumer is aware of inherent sensory characteristics on the basis of a consumer concept which is difficult to be objectively defined, is not influenced by a scheme in which a grade scale is used, and can objectively measure, by measuring a signal-to-noise ratio, the degree of perception or recognition of inherency according to how coherently a consumer can detect a signal, other than a grade score granted by the consumer. Therefore, the present invention can be valuably used for a method for quantitatively measuring a sensory perception quality of food.
