PROPIONIC ACID TRANS-2-HEXEN-1-YL ESTER Usage And Synthesis

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.

Aroma threshold values

Aroma characteristics at 1.0%: green, fruity apple and pear pulp with creamy and powdery nuances.

Taste threshold values

Taste characteristics at 1 to 5 ppm: green, oily fruity with a slight soapy mouthfeel
