ABSTRACT
“A flavor is a substance which may be a single chemical entity, or a blend of chemicals of natural or synthetic origin, whose primary purpose is to provide all or part of the particular effect to any food or other product taken in the mouth.” Nutraceuticals are products that are intended to supplement the diet because of enrichment in vitamins, minerals, amino acids, herbs or other botanicals; it is a concentrate, metabolite, constituent, extract, or combination of these ingredients. Flavors were added into the food and lives well before recorded history. During the First World War, the US food industry started to grow at the significant rate. During this phase, the trade between Germany and the United States was banned, and most of the artificial flavor companies were in Germany. The flavor compounds that arouse the taste perceptions should dissolve in the saliva before they can be perceived.
