Aroma
Powerful and diffusive, fruity-sweet odor,
free from fatty notes. More fruity, more sweet
than the cis-isomer, and not so dry in its
greenness.
The taste is powerfully fruity, somewhat
green, but sweet in dilutions below 5 ppm.
Chemical Properties
(E)-2-Hexenyl propionate has a fruity odor with a ripe apple/pear note
Occurrence
Reported found in guava, black tea and fresh plums.
Uses
Propionic acid trans-2-hexen-1-yl ester lends itself more to flavor tompositions than to perfumes. It could be used
in Tutti-frutti:compositions as a powerful
factor, or as a modifier in Apple, Pear, Pineapple or Peach, but it is not quite as versatile
as the Acetate or the Butyrates.
Production Methods
Propionic acid trans-2-hexen-1-yl ester can be produced by esterification of trans-2-Hexenol
with Propionic acid under azeotropic conditions.
Definition
ChEBI: The propanoate ester of (2E)-hex-2-en-1-ol.
