Abstract:
The invention relates to the use of 5,5-dimethyl-3-ethyl-3,4-dihydrofuran-2-one (A), named “Noxolide” by the applicant, as an olfactory agent in perfumery, and also as a food flavouring. The invention also relates to a novel process for the preparation of 5,5-dimethyl-3-ethyl-3,4-dihydrofuran-2-one.
Abstract:
Method for stereoselectively preparing a (R) or (S) gamma-lactone consists in microbially biosynthesizing gamma-lactone, wherein the biosynthesis is carried out from a substrate selected from C5 to C20 fatty acids with the aid of a strain selected from those enabling a stereoselective hydroxylation in C4 of the substrate, in particular Aspergollus sp or Mortierella sp. The biosynthesis of the gamma-lactone and the use thereof in perfumery and for food flavouring agents are also disclosed.
Abstract:
A process for the production of natural ferulic acid, coniferyl alcohol and/or vanillin, includes the bio-conversion of eugenol by a bacteria belonging to the Streptomyces genes including at least one nucleotide sequence SEQ ID NO:1 or SEQ ID NO:8 or any nucleotide sequence having at least 70%, preferably 80% and very preferably 90%, identity with the sequence SEQ ID NO:1 or SEQ ID NO:8.

Abstract:
A smoking device includes a recipient or able to receive burning products, preferably tobacco, and a filter element connected to the recipient, wherein the filter includes at least one breakable capsule, the capsule having a initial crush strength from 0.5 to 2.5 kp, and keeping a crush strength from 0.5 to 2.5 kp and a deformation of less than two third of its diameter prior to rupture after having been submitted to a smoking test. The invention is also relating to the capsule suitable for being incorporated in a smoking device, and to the process of manufacture of the capsule.
Abstract:
The invention concerns a novel compounds of formula (I), wherein the dotted line bond is present or not, and wherein R1 represents: when the dotted line bond is present —CHCH3OH or —CHCH3 OCOR or —CHCH3XCH2CHOHR′ or —CHCH3OCHR′CH2OH or formula (II) when the dotted line bond is absent —CHCH3OH or —CHCH3OCOR or —COCH3 or formula (II) or —CHCH3XCH2 CHOHR′ or —CH2CH2XCH2CHOHR′ or —CHCH3OCHR′CH2OH or —CHCHCOR′ or —CH2CH2CHR′OH or —CH2CH2CHR′OCOR or CHCHCHOHR′ or —CHCHCHR′OCOR, wherein R represents H, Me, Et, Pr, isoPr, But, isoBut, CH3CH2)4, (CH3)2CHCH2, CH2CH, (CH3)2CCH, and R′ represents H, Me or Et, and X represents O, N or S, and their preparation method. Because of their fragrance, said compounds are highly interesting for the perfume industry, for cosmetic and care products.
Abstract:
A process of preparing a compound of formula (I) wherein R represents a linear or branched C5 alkyl group, as well as the use of such compounds in a fragrant and/or flavoring composition.
Abstract:
A method for masking or modifying the olfactory or gustatory sensation generated in a user by a base product (7) includes releasing an aromatic or fragrant composition over time in a sequenced manner in relation to the release of the base product (7), the aromatic or fragrant composition being housed in at least one rupturable container (5). A device used to implement the method is also disclosed.
