ABSTRACT:
The present invention relates to a process for producing cis-3-hexen-1-ol from an unsaturated fatty acid, in which said synthesis is carried out from the latter by the combined action of a natural system of enzyme(s) allowing the oxidation of said fatty acid to cis-3-hexenal and of a yeast allowing the reduction of cis-3-hexenal to cis-3-hexenol in a culture medium. According to a first characteristic of the present invention, the enzymatic system consists of a plant mass obtained by grinding leaves harvested whole without predilacerating them. According to a second characteristic of the present invention, the enzymatic system is introduced in the form of a ground cellular product obtained by grinding followed by cell disintegration. Finally, advantageously, a reagent chosen from a ferrous cation, acetylsalicylic acid, chlorophyll B and the enzyme catalase, makes it possible to increase the yields of cis-3-hexenol.
