  • Patent number: 10993464
    Abstract: A method to confer, enhance, improve or modify the flavor properties of a flavoring composition or flavored article by adding to the composition or article the compound 3-mercaptoheptyl acetate or an optically active enantiomer thereof in an amount effective to provide a flavor base having top notes of the citrus-grapefruit, teas and/or peach type and/or red fruit. The compound is typically added to provide an amount of from 0.0001 to 500 ppm in the flavoring composition or flavored article. Also, the resultant flavored composition or flavored article.

  • Patent number: 9073966
    Abstract: The present invention relates to a method for screening compounds having the ability to prevent, suppress or reduce malodor development on body surfaces. In particular, the method allows to efficiently screen for compound having the ability of preventing sweat malodor development caused by volatile sulfur compounds (VSCs). The present invention is based on the finding of the direct precursor of naturally VSCs, which is present in human sweat and which will be metabolized by Staphylococci to VSCs.
