Evaluation of Psychological Measurements during Consumption of Flavored Jelly Beverages

Abstract

There is an increasing demand for foods that are not only tasty and healthy but also contribute to mental health. Herein, the subjective moods of 11 participants (six males and five females) were measured to evaluate the effects of consuming flavored jelly beverages on their emotional sensitivity. To investigate the effects of food quality factors, the four test samples were a flavored jelly beverage, a flavored jelly beverage without flavor (fruit juice and flavoring), a flavored jelly beverage without a gelling agent, and water. The effects of flavor and gelling agent were compared, and the subjective moods of the participants were evaluated before and after the consumption of the test sample. Principal component analysis of mood differences before and after sample consumption revealed that the first and second principal components represented “pleasure-displeasure” and “arousal-sleepiness”, respectively. The analysis also reported that the flavor and gelatinization increased pleasure and arousal, respectively.
