Food chemistry
Food coloring is any substance that is added to food
or drink to change its color.
Food coloring is used both in commercial food production and in domestic cooking.
People associate certain colors with certain flavors, and the color of food
can influence the perceived flavor, in
anything from candy to wine. For this reason, food manufacturers add dyes to their
products.
Flavor is the sensory impression of a food or other substance,
and is determined mainly by the chemical senses of taste
and smell. The flavor of the food, as such, can be
altered with natural or artificial flavorants, which
affect these senses.

Food additives are substances added to food for preserving flavors, or improving taste or appearance. These processes are as old as adding vinegar for pickling or as an emulsifier for emulsion mixtures
