There are quite a few studies that indicate how food must be of an inviting colour, since it is then possible to attribute - more or less correctly - the typical virtue of genuine and tasty food: this is why, starting from more or less natural, you can obtain a food coloring to use to make what you eat even more fascinating. Food coloring plays an increasingly important role in the preparation of foods, especially at an industrial level: in many cases it is used to enhance certain flavors or aromas, while in other cases it is used to give an unusual appearance to what is serves on the plate.
