Sensory science is often focused on optimizing the palatability of food and beverage. However, the smell, taste and texture of foods and beverages also have a functional role in determining eating behavior. Ambient smells prime people for sensory specific appetites. Taste intensity signals the nutrient content of foods, and plays a dominant role in satiation. Texture determines the eating rate and has an immense effect on how much people eat. Sensory is key to nutrition.
