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: The invention relates to alkyl (3-methylthio)-butyrates wherein the alkyl group has 4 to 5 carbon atoms, to their use in flavor compositions and to the use of these compounds or flavor composition comprising these compounds in foodstuffs and stimulants. The compounds impart a fresh fruit flavor character. Preferred is isobutyl (3-methylthio)-butyrate.

Abstract: Perfume compositions and perfumed products characterized by a content of one or more fragrances having a long-lasting flowery and somewhat spicy odor with a not very pronounced sulphurous note and corresponding to the formula ##STR1## wherein R represents a methyl or ethyl group.

Abstract: The invention relates to a method for the preparation of both known and novel fragrances and flavors, and in particular to the preparation and use of the novel fragrance compound, 2,6-nonadiene nitrile, and to a novel method for the preparation of 4-heptynal as the starting product for the preparation of the 2,6-nonadiene nitrile fragrance compound.

Abstract: Safranic acid esters having the general formula ##STR1## wherein the dotted lines represent two conjugated double bonds in the positions 2 endocyclic and 4 (.alpha.-isomer), 1 and 3 (.beta.-isomer) or 2 exocyclic and 3 (.gamma.-isomer), R.sub.1 represents an alkyl group containing at least 2 carbon atoms, or, in the .gamma.isomers an alkylidene group with 2 or 3 carbon atoms and R.sub.2 represents an alkyl or alkenyl group with 3 or 4 carbon atoms in the form of a perfumed product or flavoring composition. A process for the preparation of a perfumed product or flavoring composition wherein the safranic acid esters are incorporated with other suitable constituents.

Abstract: The invention relates to the preparation of perfume compositions. More specifically the invention relates to the use of new 1,5-alkadien-4-ols and esters derived therefrom as components of such compositions.
