The Chemical Signatures of Taste: Characterizing Flavor Compounds in 50 Foods/Flavors

Characterizing flavor compounds are the chemical fingerprints of our food—the essential molecules that tell our senses exactly what we are eating. They are the reason a single whiff can distinguish a ripe strawberry from a crisp apple, or a sip of coffee from a bite of dark chocolate. These key compounds form the distinct identity of a flavor, acting as the primary signal that allows the brain to instantly recognize and differentiate one food from another.

The following is a list of 50 foods and flavors, each defined by its primary characterizing flavor compound(s). This data, cited from the book The Technology of Food Flavoring, includes the associated flavor notes as well as the taste and aroma perception thresholds for each compound.
