    Abstract: The present invention primarily relates to a method for producing a compound of formula (I) and/or a physiologically acceptable salt thereof from vanillylmandelic acid and/or a physiologically acceptable salt thereof. The present invention further relates to the simultaneous use of one or more iodide salt(s) or hydrate(s) thereof, one or more reducing agent(s), one or more inorganic and/or organic acid(s) other than phosphonic acid, and methanol and/or a physiologically acceptable salt thereof or an alcohol of formula (II) as defined herein and/or a physiologically acceptable salt thereof for converting vanillylmandelic acid and/or a physiologically acceptable salt thereof into a compound of formula (I) and/or a physiologically acceptable salt thereof or into a compound of formula (III) as defined herein and/or a physiologically acceptable salt thereof.

    Abstract: A method for producing branched aldehydes is proposed, the method comprising the following steps: (a) providing a culture of one or more fungi of the genus Conidiobolus and producing biomass containing branched carboxylic acids in free and/or bound form; (b) extracting the biomass from step (a) to produce a first intermediate containing free and/or bound carboxylic acids; (c) optionally chemically, enzymatically or microbially hydrolyzing the bound carboxylic acids from the first intermediate; (d) treating the first intermediate with a reducing agent of a chemical nature to convert the free and/or bound carboxylic acids into the corresponding alcohols and optionally separating one or more alcohols from interfering by-products and producing the chemically produced second intermediate containing these alcohols as a mixture or in enriched form; (e) treating the first intermediate with a reducing agent of a biological nature to convert the free and/or bound carboxylic acids into the corresponding aldehydes having the same number of carbon atoms compared to the free and/or bound carboxylic acids or into the corresponding aldehydes having a reduced number of carbon atoms by one compared to the free and/or bound carboxylic acids and producing the biologically produced second intermediate containing these aldehydes; (f) treating the chemically produced second intermediate with an oxidizing agent of a chemical nature to convert the free and/or bound alcohols into the corresponding aldehydes; and optionally (g) removing interfering by-components from the fractions obtainable after step(s) (d) and/or (e) and/or (f).

    Abstract: The present invention relates to, according to a primary aspect, a method for manufacturing a mixture comprising rotundone. A further aspect of the present invention relates to mixtures containing rotundone as well as their use for generating, imparting or modifying, preferably enhancing, one or several taste and/or olfactory impressions. Moreover, the invention relates to a pharmaceutical preparation for nutrition, for oral care or for pleasure or a cosmetic pharmaceutical preparation or a pharmaceutical preparation intended for oral consumption or an intermediate good for manufacturing a pharmaceutical preparation for nutrition, for oral care or for pleasure or a cosmetic pharmaceutical preparation or a pharmaceutical preparation intended for oral consumption comprising a mixture according to the invention and furthermore to a method for manufacturing said preparation or intermediate good.
