紅茶キャラクターホイールの作成と紅茶特徴の可視化

摘要

The characteristics of black tea consist of three components; aroma, taste and liquor color. However, since perception and expression of these characteristics, particularly aroma and taste, varies according to the individual, describing them in a way that is comprehensible to a majority of people can be problematic. Thus a glossary of specific terms is required which can be used to accurately assess these characteristics in the development and quality control of tea products, and to clearly convey the complex and subtle qualities of black tea to consumers in Japan. Our character wheel for black tea was created as a means of bringing more people to a common understanding of the widely varied black tea characteristics of aroma, taste and color. On the basis of sensory evaluations using the character wheel we compiled pictorial charts visually depicting the characteristics of various types of black teas.%紅茶の特徴は香り•味•水色の3つの要素から成る.その多彩な特徴の捉え方や伝え方は人によって様々であり，特に香りや味を言葉で表現し，多くの人に伝えることは非常に難しい.よって，紅茶の複雑であいまいな特徴を，製品開発や品質検査においても的確に評価するために.紅茶の特徴を明確に表す評価用語を作成した.また，日本の消費者に紅茶の特徴をわかりやすく伝えるためのツールとして有用である.我々は，紅茶の香り•味•水色の特徴について，より多くの人と共有し，伝達するためのコミュニケーションツールとしての紅茶キャラクターホイールを作成し，その効果を示した.また，紅茶キャラクターホイールに基づいて紅茶の特徴を可視化した．
