臭気の官能試験におけるパネル評価の信頼性と統計的特性

摘要

本研究で得られた成果をまとめると以下の通りである。 1）多数パネル評価を、合計で同数の評価個数となる少数パネル複数回評価で代用する可能性の検討として、1-butanolの検臭実験を行い、60名による1回の評価と選抜6名による10回の評価の評価傾向を比較した。%It is necessary to prepare a plenty of subjects in order to ensure the statistical confidence in the sensory evaluation of odor. Therefore, it is convenient if the minimum number of subjects can be prepared according to the necessary accuracy of measurement. In this paper, the sensory evaluation experiment with 1-butanol was conducted and evaluations by six subjects were compared with those by sixty subjects under the same sixty votes in total. Moreover, confidence intervals of intensity and percentage of person dissatisfied were estimated, and relationships between confidence intervals and the number of subjects were indicated.
