Abstract
Nineteen additional, mainly in trace amounts, occurring volatiles of pineapple fruit—including four nonterpenoid hydrocarbons and a number of carboxylic esters—have been isolated under enzyme inhibition, enriched by liquid-liquid extraction, fractionated on silica gel, and identified by gas chromatography and coupled GC-MS. Among them, 1-(E,Z)-3,5-undecatriene and 1-(E,Z,Z)-3,5,8-undecatetraene may contribute to the typical flavor of pineapple. They combine a fragrant odor with extremely low odor detection thresholds. The corresponding E,E and E,Z,Z isomers are much less odorous (factors of 106 and 104, respectively). Disintegration of the fruit tissue without enzyme inhibition causes a rapid decrease of all undecaenes.
