The Vital Components Citrus oils are rich in nonpolar terpene hydrocarbons. The main terpene constituents are not always major contributors to the flavor or odor. It is the polar components (oxygenates) that usually contribute the most to fl avor and odor. These include:
• Esters, such as ethyl butyrate
• Aldehydes, such as octanal, decanal, dodecanal, trans-2-hexenal, hexanal and citral
• Oxides, such as 1,8 and 1,4-cineole
• Alcohols, such as geraniol, nerol, borneol and terpinen-4-ol
• Acids, such as octanoic and decanoic acid The odor and fl avor of each of these natural molecules contribute to the complex interaction of components, creating a natural citrus odor and fl avor profile.
