Chemical Information
FooDB NameHexyl butyrate
DescriptionButanoic acid-hexyl ester or hexyl butyrate belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid consisting of 6 or more carbons. Hexyl butyrate is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. It is a clear, colorless liquid obtained by the formal condensation of hexanol with butyric acid. Hexyl butyrate has a sweet, slightly waxy, fruity, apple, and apple peel aroma, with a similar green/soapy taste. Hexyl butyrate occurs naturally in many fruits and has been detected, but not quantified in apples, yellow passion fruit, roman camomiles, pears, sweet cherries, and other fruits. This could make hexyl butyrate a potential biomarker for the consumption of these foods. Hexyl butyrate is one of the main volatile chemicals released by the Tarnished plant bugs, Lygus hesperus and Lygus lineolaris when they are attacked or disturbed ( PMID: 12775153).
