Pyridines of formula ##STR1## wherein R.sup.1 stands for a saturated linear alkyl radical having 6 to 8 carbon atoms, or for a 4-methylhexyl radical, and R.sup.2 represents either a hydrogen atom or, when R.sup.1 has 6 carbon atoms, a hydrogen atom or a methyl radical, are used in the reconstitution of orange essential oil as well as for flavoring orange juice. They are also useful ingredients in the reproduction of flavors of the seafood, fishy type. Pyridines (I) are also used in perfumery.

Use of pyridines as perfuming and flavoring ingredients

3,10-Diacetyl-11-isopropylidene-7,7-dimethyl-tricyclo[6.2.1.0.sup.2,6 ]undeca-2,5,9-triene is a flavoring ingredient useful for the aromatization of smoking articles. It develops upon smoking green, slightly floral, metallic, astringent, fatty, slightly bitter and earthy notes. It is prepared by a two-step process from 1-(4-isopropylidene-1-cyclopent-1-enyl)-1-ethanone.

Tricylic ketone and use of same as flavoring ingredient

1(7)-p-Menthen-9-al, a novel terpene aldehyde, possesses useful organoleptic properties and develops bitter, herbal and aromatic perfume notes. In the field of flavors, 1(7)-p-menthen-9-al develops flowery, herbal and fatty characters reminiscent of certain aspects of the flavor of nuts or cumin.

1(7)-p-Menthen-9-al and its utilization as perfuming and flavoring

1(7)-p-Methen-9-al, a novel terpene aldehyde, possesses useful organoleptic properties and develops bitter, herbal and aromatic perfume notes. In the field of flavors, 1(7)-p-menthen-9-al develops flowery, herbal and fatty characters reminiscent of certain aspects of the flavor of nuts or cumin.
