The invention relates to novel mixtures, containing or consisting of a first compound (E) and a second compound (Z), wherein compounds (E) and (Z) are compounds of formula (I) having an identical structural formula, wherein one of the four wavy lines denotes a double bond and the other wavy lines each denote a single bond and X is selected from -O-, -CH2-, and -O-CH2-, and the first compound (E) is trans-configured and the second compound (Z) is cis-configured, wherein the weight ratio of compound (E) to compound (Z) in the mixture lies in the range of 10 : 90 to 65 : 30, preferably 65 : 35, especially preferably 60 : 40. The invention further relates to uses of such mixtures, to methods for producing such mixtures, and to products containing such mixtures.
