Abstract

The present invention relates to a natural vanillin composition comprising at least one compound selected from the group consisting of 4-((4-hydroxy-3-methoxybenzyl) oxy)-3-methoxybenzaldehyde and 4-hydroxy-3-(4-hydroxy-3-methoxybenzyl)-5-methoxybenzaldehyde. The invention also relates to a method for obtaining a natural vanillin composition according to the invention.

Description

[0001] This application claims priority from patent application number 1908643 filed in France on July 30, 2019, the content of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a natural vanillin composition comprising at least one selected from 4-((4-hydroxy-3-methoxybenzyl)oxy)-3-methoxybenzaldehyde and 4-hydroxy-3-( Compounds of 4-hydroxy-3-methoxybenzyl)-5-methoxybenzaldehyde. The invention also relates to a method for obtaining the natural vanillin composition according to the invention. Background technique [0003] Vanillin or 4-hydroxy-3-methoxybenzaldehyde can be obtained by different methods known to those skilled in the art, in particular by the following three routes: [0004] - A "natural" approach based on biotechnological methods, including in particular the cultivation of microorganisms capable of bioconverting the fermentation substrate into vanillin. Such a process in which the fermentati...
