Color and sensory perception in food/beverages

Color – Preference Test How a food or beverage affects the senses is more important to most consumers than other criteria for food selection!!! Color can denote the ripeness, strength of dilution, and even degree to which the food was heated. Black bananas, barely yellow lemonade, and scorched macaroni send visual signals that may alter a persons choices. Sight and Color: Color can be deceiving; if the colors of two identical fruit-flavored beverages are different, people often perceive them as tasting different even though they are exactly the same. For your first assignment you will need the following materials: A lemonade flavored beverage Food coloring Plastic cups Willing participants (2-4) WITH OUT LETTING YOUR PARTICIPANTS SEE YOU 1.
