The present invention relates to the novel flavor and fragrance use of 2,6-dipropyl-5,6-dihydro-2H-thiopyran-3-carbaldehyde.

Flavor and fragrance compositions containing thiopyran-carbaldehyde

The present invention is directed to a novel compound, 2-mercapto-5-methyl-4-heptanone, a process of augmenting, enhancing or imparting taste to a material selected from the group consisting of a foodstuff, a chewing gum, a medicinal product, and toothpaste comprising the step of incorporating an olfactory acceptable amount of 2-mercapto-5-methyl-4-heptanone, and a process of improving, enhancing or modifying a fragrance formulation through the addition of an olfactory acceptable amount of 2-mercapto-5-methyl-4-heptanone.

2-mercapto-5-methyl-4-heptanone and its use in flavor and fragrance compositions

The present invention relates to novel compounds having sweet, salt or umami taste enhancement qualities. These compounds have the structure:  where Ris H or methyl;Ris selected from the group consisting of H, C1-C4 alkyl, alkenyl;Ris selected from the group consisting of H, phenyl, C1-C10 straight or branched chain alkyl, alkenyl, alkynyl, alkyldienyl, acyclic or containing no more than one ring, which contains no more than a total of five heteroatoms selected from F, O, S, N, and P; and if R&#x2550;H, Rand Rtaken together can represent cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, or cyclohexenyl, which contains no more than two of each heteroatom selected from N, O, and S;or if R, Rand Rtaken together can represent one, or two aromatic rings, which contain no more than three of each heteroatom selected from F, N, S, and O.Ris selected from the group consisting of H, methyl or ethyl;Ris selected from the group consisting of H, methyl and ethyl;Ris selected from the group consisting of H, C1-C9 straight or branched chain alkyl, alkenyl, alkyldienyl, acyclic or containing no more than one ring;except for in the case of structurewhen if R&#x2550;H or methyl and R&#x2550;H or methyl, Ras described above and phenyl;or when R, R, and Rtaken together can be equal to Ris selected from the group consisting C1-C4 alkyl, or alkenyl.

Unsaturated cyclic and acyclic carbamates exhibiting taste and flavor enhancement effect in flavor compositions

Described is a new cooling agent represented by Structure I and compositions with known coolers having cooling properties and the application of Structure I in foodstuffs and chewing gum: 

Menthylcarboxamides and their use as cooling agents

The present invention is directed to novel compounds and a process for augmenting or imparting a flavor enhancement effect or modifying the perception of one or more of the five basic taste qualities sweet, sour, salt, bitter and umami, to a foodstuff, chewing gum, medicinal product, toothpaste, alcoholic beverage, aqueous beverage, snack, sauce or soup comprising the step of adding to a foodstuff, chewing gum, medicinal product, toothpaste, alcoholic beverage, aqueous beverage, snack, sauce or soup a flavor enhancement or modification of basic taste quality augmenting, enhancing or imparting quantity and concentration of at least one N-substituted unsaturated alkyl amide defined according to the structures: 

Saturated and unsaturated N-alkamides exhibiting taste and flavor enhancement effect in flavor compositions

The use of novel methanoazulenofuran and methanoazulenone compounds for use as fragrance chemicals, suitable for use incorporated in a wide variety of products such as perfumes, colognes and personal care products having a structure  with the ring carbon at the X position, X is absent; and

Methanoazuenofurans and methanoazulenone compounds and uses of these compounds as fragrance materials

The present invention is directed to novel cyclopropanecarbonitrile compounds of the general formula wherein X is a hydrogen, or a straight, branched, or cyclic hydrocarbon moiety consisting of less then 30 carbon atoms and containing single and/or double bonds; Z is a hydrogen or a straight, branched, or cyclic hydrocarbon moiety consisting of 1 to 30 carbon atoms and containing single and/or double bonds and Y is a nitrile.
