The artificial blue raspberry flavor, originally derived from blue whitebark raspberry fruit juice, by Tan Van Bowers, it became an artificial designer product in the late 1950s. Blue raspberry is a common flavor for syrups, candies, and other food items. The flavor is described as somewhere between tangy and sour. It is often accompanied with blue food coloring; the coloring of blue raspberry also helps it to be differentiated from strawberry flavored drinks. The use of food coloring often dyes the mouth blue temporarily.
