Definition
ChEBI: An acetate ester that results from the formal condensation of acetic acid with (Z)-hex-3-en-1-ol.
In dilutions below 10 ppm, it produces very pleasant fruity-green flavours, and its taste individually at concentrations below 2 ppm is distinctly Banana-1ike. Very interesting combination flavors can be created with this ester and a few other chemicals: A concentration of about 1 ppm of cis-3-Hexenyl acetate in the presence of 0.05 ppm Allyl-iso-thiocyanate (Allyl mustard oil) will produce a distinct note of unripe Banana with the sharp greenness and the fruity notes unmistakably identifiable as Banana and absolutely no impression of Mustard. The two materials separately at the concentrations indicated give very weak and incomplete flavor pictures. However, this ester finds considerable use in perfumes, where it may lend pleasant and natural freshness to delicate florals (Muguet, Lilac, Narcisse, etc.) and participate in creating true-to-nature, foliage-green topnotes in other fragrance types. The ester is most likely to supersede the less stable and less natural-smelling Alkyl acetylenic esters, slowly being abandoned in modern perfumery.
