Abstract: The invention relates to foodstuffs having a savory flavor, to a process for their preparation and to compositions having a savory flavor which products comprise (hydrogenated) 2-methyl-3-furanthiol and/or a derivative thereof and methanedithiol and/or a derivative thereof. Under derivatives are here to be understood their esters like thioacetates, their thioethers like methyl sulfides their disulphides etc. The combination of the above identified two groups of sulphur compounds in ppb levels leads to a foodstuffs with powerful flavor reminiscent of beef broth.

Abstract: A mixture of disaccharide esters of 3-methylpentanoic and acetic acid is prepared and used as flavor precursors. The esters average at least 4 and preferably at least 4.5 3-methylpentanoyl groups per disaccharide moiety, with remaining positions being substantially occupied by acetyl groups. Suitable disaccharides are sucrose and lactose. Preferably the disaccharide ester has an acetyl/methylpentanoyl group ratio of about 2.3 to 3.2:4.8 to 5.7. The disaccharide esters are suitable for flavoring products undergoing a heating step during preparation or consumption, such as ingredient mixes for extrusion, frying or baking, and especially tobacco. On heating they liberate 3-methylpentanoic acid and/or its decomposition products.

Abstract: Perfume compositions, perfumed materials and perfumed articles containing derivatives of spiro [5.5] undecane-3-one and/or undecene-3-one having the following formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen or methyl and the dotted line is a single or double bond with the proviso that when this dotted line is a double bond R.sub.1 and R.sub.2 are both hydrogen.The use of one or more derivatives of spiro [5.5] undecane-3-one and/or -undecene-3-one having formula 1 as a perfume component in perfume compositions and in imparting fragrance to materials and articles for example soaps, cleaning preparations and cosmetic preparations.

Abstract: Perfume compositions, perfumed materials and articles containing one or more phenyl-tetrahydrofurans.Use of one or more phenyl-tetrahydrofurans having formula 1 or 2 of the formula sheet in which R.sub.1, R.sub.2 and R.sub.3 each represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms and R.sub.4 represents a hydrogen atom, a methyl- or ethyl group as a perfume component in perfume compositions and in imparting perfume notes to materials and articles for example soaps, cleaning agents and cosmetic preparations.
