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 concerns the use of 3-(3-Hydroxy-4-methoxy-phenyl)-1-(2,4,6-trihydroxyphenyl)propan-1-one for masking, reducing or suppressing an unpleasant taste impression, preferably bitter, sour and/or astringent taste impression of unpleasant-tasting substances or mixture of substances, preferably bitter-, sour-, and/or astringent-tasting substances or mixtures of substances, and in particular the bitter taste impression of bitter-tasting substances, and/or modulating the taste impressions selected from the group consisting of cooling, umami, fruity and spicy notes of cooling-, umami-, fruity- or spicy-tasting substances or mixture of substances, and simultaneously intensifying the sweet-taste impression of sweet-tasting substances or mixtures of substances or both sweet- and bitter-tasting tasting substances or mixture of substances.
