  • Ethers for aromatizing purposes
    Patent number: 5432154
    Abstract: The invention relates to novel ethers and their use as aroma precursors. The ethers are derived from ionol and related compounds. These aroma precursors do not have a substantial aroma as such under ambient conditions, but will break up into a complex mixture having useful organoleptic properties under heating. The ethers are especially suitable for use in products which are heated, burned or smouldered in some stage of their use. The compounds according to the invention are especially suitable for application to tobacco. Mixtures obtained by degrading (e.g. by heating) the ethers according to the invention may be used in a flavoring or perfuming mixture as well due to their organoleptic properties.
