Abstract

Official abstract text for this publication.

A fragrance precursor represented by formula (1): wherein R 1 represents a hydrogen atom, an alkyl group having a carbon number of 1 to 12, a hydroxy group, a methoxy group or an ethoxy group R 2 represents a single bond, an alkylene group having a carbon number of 1 to 2, which may have a substituent, or a vinylene group which may have a substituent; and R 3 represents a residue resulting from removal of one hydrogen atom of a hydroxy group from a fragrance alcohol having a carbon number of 5 to 20 or a phenol which may have a substituent.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for releasing a fragrance alcohol, a phenol or a phenol derivative, comprising reacting a fragrance precursor of the following formula (1) with a microorganism in a microbial culture, wherein R 1 represents a hydrogen atom, an alkyl group having a carbon number of 1 to 12, a hydroxy group, a methoxy group or an ethoxy group; R 2 represents a single bond, an alkylene group having a carbon number of 1 to 2, which may have a substituent, or a vinylene group which may have a substituent; and R 3 represents a residue resulting from removal of one hydrogen atom of a hydroxy group from a fragrance alcohol having a carbon number of 5 to 20 or a phenol which may have a substituent, wherein the microorganism is one or more species selected from the group consisting of Bacillus subtilis and Moraxella osloensis, an amount of the microorganism in the microbial culture is from 10 3 to 10 12 cfu/mL, and a mass of the fragrance precursor at the time of mixing with the microbial culture is from 0.01 to 10 mg per 1 mL of the microbial culture.
