  • Volatile compounds trap desorption device and method for desorbing volatile compounds from a trap
    Patent number: 9222855
    Abstract: A method for restoring a volatile compound from a trapping means, wherein the method includes a flowing step wherein a carrier gas flows through the trapping means, at a controlled rate, by increasing the volume of a chamber located downstream of the trapping means is disclosed. The invention also relates to a device for implementing the method. The invention allows to faithfully restore the compounds that have been previously trapped and to faithfully restore the trapped odors.

  • Foodstuffs that include sulfur-containing flavorings
    Publication number: 20020098270
    Abstract: A food composition containing a flavoring agent of a precursor mixture of flavorings. The precursor mixture of flavorings includes at least one polysulfide and at least one non-volatile source of sulfur having at lease one sulfhydryl group. The precursor mixture generates an aromatic note due to the formation of thiols when heated above 50° C. to provide a roasted or grilled aromatic flavor note to the food composition.
