Abstract
Evaluating the "deliciousness" of a food is complicated by the diversity of people who eat it, in addition to the fact that the itself is multifaceted. In this study, we focused on changes in emotions during food intake to evaluate humans, who have such diversity. In order to clarify the relationship between food intake and associated emotions, we attempted to quantify emotions based on the Russell’s circumplex model, which consists of two dimensions: arousal-sleepiness and pleasant-unpleasant. First, the participants were asked about the most memorable foods eaten within the past few days, and then asked to recall the actual mood they felt when consuming it, and words and phrases related to emotions were collected through free descriptions. Based on the results, words and phrases usable in the circumplex model were selected, and emotional coordinates for food intake were created. Using this coordinate, we will discuss their relationship to food.
