The invention relates to flavoring compositions characterized by an effective amount of gamma-jasmolactone having the formula ##STR1## as well as the use of these flavorings or gamma-jasmolactone per se for imparting, enhancing or improving the flavor, in particular the fruity character of foodstuffs and drinks.

Flavoring composition containing gamma-jasmolacton

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.

Mixture of disaccharide esters of 3-methylpentanoic acid and acetic acid

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.

Flavoring with alkyl (3-methylthio)-butyrates

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.

Perfume compositions and perfumed products which contain an alkyl

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.

Method for the preparation of fragrances, and method for the preparation

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.

Safranic acid ester perfume compositions

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.
