Abstract: The present invention relates to a process for preparing natural raspberry ketone, comprising a step (a) of bioconversion of p-coumaric acid allowing the preparation of p-hydroxybenzaldehyde, a step (b) in which the p-hydroxybenzaldehyde obtained on conclusion of step (a) is condensed with acetone to allow the formation of p-hydroxybenzalacetone, a step (c) in which the p-hydroxybenzalacetone obtained on conclusion of step (b) is converted into raspberry ketone by bioconversion or biocatalysis.
