Effects of Appearance in Visual Palatability of Dishes for the Elderly under Several Lighting Conditions

This study aims to clarify the effect of the appearance of dishes on the visual palatability for elderly people concerning its color appearance, glossiness, and visual texture. We conducted a subjective experiment on visual palatability of dishes under different light sources. We used the digital images of 12 kinds of food dishes to give the subject the same visual stimuli with no olfactory cues. As a result, we found that elderly’s “visual palatability” was affected by not only the “color appearance” but also the “glossiness” of dishes.
