ABSTRACT 1‐(E,Z)‐3,5‐undecatriene and 1‐(E,Z,Z)‐3,5,8‐undecatetraene were isolated under enzyme inhibition from edible parts of peach, passion fruit, and kiwi; the triene only was found in celery, parsley, mandarine, apple and pear. Capillary gas chromatography, sniffing‐capillary gas chromatography, and combined “live”‐capillary gas chromatography‐mass spectrometry of the concentrated liquid‐liquid extracts were used to establish their identity. Owing to their ultra‐low odor detection thresholds and the proposed biogenesis, these trace compounds may be “character impacts” in a wide variety of food flavors of plant origin.
