  • Patent number: 6708550
    Abstract: Aroma chemicals emitted from an aroma-emitting source are obtained by an apparatus and process for obtaining the chemicals. The apparatus includes the use of one or more capillary tubes which have on their interior surfaces an absorbent material, a suction device for drawing the aroma chemicals through the capillary tubes, and a connecting tube which connects the capillary tubes and the suction device. A system for collecting and analyzing the aroma chemicals emitted from an aroma-emitting source is disclosed which has one or more capillary tubes, a suction device, a connecting tube, a thermal desorber which desorbs the aroma chemicals directly from the capillary tubes, a cryogenic focusing device, and a gas chromatograph/mass spectrometry instrument.

  • Patent number: 6325859
    Abstract: A method for preparing beads containing at least one active ingredient, such as a flavor, fragrance, vitamin, and/or coloring material, to food or tobacco products, where the active ingredient is released at a controlled rate. Discrete droplets of the active ingredient and an acid polysaccharide are formed in an aqueous medium, then the droplets are converted to water insoluble gel beads by introducing the droplets into a solution containing multivalent cations, thereby building a suspension of gel beads. The beads may then be added to the food or tobacco product in an effective amount to flavor, perfume, vitamize, and/or color the product. The beads are heat and mechanically stable.

  • Patent number: 6306818
    Abstract: The invention relates to fragrance precursors, In particular, the invention relates to the use of several classes of compounds which may act as fragrance precursors, e,g., in cosmetic products such as deodorants and antiperspirants and in laundry products such as detergents and fabric softners. These compounds are odorless, but upon contacting the skin as example, in skin care compositions or in personal care compositions, produce fragrances. The compounds also produce fragrances when used in the presence of lipases, e.g. as used in (laundry) detergents, thus providing a prolongation of the fabric scenting effect. The compounds under consideration are compounds of the formula I: The substituents are defined in the specification.
