Abstract: Use of vanillyl lignans comprising e.g. matairesinol, 7-hydroxymatairesinol, lariciresinol, arctigenin, isolariciresinol, alpha -conidendrin, nortrachelogenin, pinoresinol, 5-hydroxylariciresinol, 2-hydroxyarctigenin, trachelogenin, phillygenol, guaiaretic acid, gnidifolin, fragransin A2, fragransin C 3b, massoniresinol, olivil, isoolivil, neo-olivil, vitedoin, vitrofolal E and/or their salts, for masking the unpleasant taste impression, preferably the bitter, astringent and/or metallic taste sensation of an unpleasant tasting substance, preferably a bittering agent, is claimed. Use of vanillyl lignans comprising matairesinol, 7-hydroxymatairesinol, lariciresinol, arctigenin, isolariciresinol, alpha -conidendrin, nortrachelogenin, pinoresinol, 5-hydroxylariciresinol, 2-hydroxyarctigenin, trachelogenin, thujastandin, busaliol, shonanin, liovil, isoliovil, koreanol, taxiresinol, phillygenol, guaiaretic acid, gnidifolin, fragransin A2, fragransin C 3b, (4-[5-(3,4-dimethoxyphenyl)-3,4-dimethyl-tetrahydrofuran-2-yl]-2-methoxyphenol), massoniresinol, olivil, isoolivil, neo-olivil, vitedoin, vitrofolal E and/or their salts, for masking the unpleasant taste impression, preferably the bitter, astringent and/or metallic taste sensation of an unpleasant tasting substance, preferably a bittering agent, is claimed. Independent claims are also included for: (1) use of a product obtained from a plant material, preferably by extraction and optionally subsequent hydrolysis, comprising the above vanillyl lignans and/or their salts, for masking the unpleasant taste impression, preferably the bitter, astringent and/or metallic taste sensation, of an unpleasant tasting substance, preferably a bittering agent; (2) use of the product or the vanillyl lignans in combination with further substances for altering or masking the unpleasant, preferably bitter taste sensation of an unpleasant-tasting substance, preferably a bittering agent; (3) a composition comprising (a1) food, nutritional supplements, oral care or preparation served for pleasure, (b1) cosmetic preparations, preferably for use in the region of head, (c1) pharmaceutical preparations for oral administration, (d1) intermediates for preparing (a1)-(c1), comprising the vanillyl lignans and/or their salts, where at least one of the unpleasant, preferably bitter tasting substance present in the composition, is not secoisolariciresinol; (4) method (1) for (a) masking the unpleasant, preferably bitter taste impression of bitter tasting substances and/or producing the composition comprising contacting the mixture of bitter tasting substances with vanillyl lignans and/or their salts; and (5) a pre-product for producing (a1) or (c1) comprising the vanillyl lignans and/or their salts, at least one carrier suitable for consumption comprising ethanol, isopropanol, glycerol, 1,2-propylene glycol, diacetin, triacetin, maltodextrin, gum arabic and/or silica, and additionally at least one different flavoring substance e.g. acetophenone, alpha-ionone, beta-ionone, anisaldehyde, benzaldehyde, benzothiazole, benzyl acetate, benzyl alcohol, butyl butyrate, butylidenephthalide, carvone, camphene, caryophyllene, cineol, cinnamyl acetate, citral, citronellol, citronellal, citronellyl acetate, cyclohexyl acetate, cymene, damascone decalactone, dihydrocoumarin, dimethyl anthranilate, dimethyl anthranilate, ethoxyethyl, ethylbutyric, ethyl butyrate, ethylguaiacol, ethyl isobutyrate, eucalyptol, eugenol, heptenal, cis-4-heptenal, trans-2-hexenal, cis-3-hexenol, trans-2-hexenoic acid, trans-3-hexenoic acid, cis-2-hexenyl acetate, cis-3-hexenyl acetate, cis-3-hexenylcapronat, trans-2-hexenylcapronat, cis-3-hexenyl, cis-2-hexyl acetate, cis-3-hexyl acetate, trans-2-hexyl acetate, cis-3-hexyl formate, isoamyl alcohol, isoamyl isovalerate and their stereoisomers, enantiomers and positional isomers, diastereomers, cis/trans-isomers and epimers.
