Attractiveness of adding color in food

Comparison of the effects of color toppings and taste toppings for hamburger steaks

Abstract

In the food industry, it has been widely demonstrated that the appearance of food affects consumers' purchasing behavior. However, in this industry, studies on the effect of food color as topping on consumer impression are scarce. Hence, we tested the following hypothesis; Addition of color by food toppings enhances the appeal of the product. The effect was evaluated by comparing the color topping (paprika) with flavor topping (sunny-side up). The hypothesis was supported by a randomized controlled trial in an online survey environment in 300 people in their late teens to 60s. The effect of color topping was the same as that of flavor topping.
