The term "enhance" is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. The resulting basic aqueous solution is then extracted with two portions 35 ml each of methylene chloride and the extracts are combined, dried, and concentrated yielding an oil weighing 1.

    In the past, prior to this last decade, it was the general opinion among those skilled in the art that straightchain compounds containing mercapto or --SH moieties were not desirable for use in conjunction with flavoring materials particularly for use in foodstuffs, because of their "rubbery" and "chemical" aromas.

Composition providing a refreshing feeling significantly similar to that provided by menthol. It is then extracted with four 25 ml portions of methylene chloride and the extracts are combined, and washed with two 30 ml portions of saturated sodium chloride. The resulting chlorinated ketone is preferably reacted with sodium hydrosulfide, which is pre-prepared by reaction of hydrogen sulfide with sodium methylate in methanol.

    Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored is relatively bland to the taste, whereas relatively minor quantitites may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma.

    The reaction mass is then transferred to a 5-liter separatory funnel and shaken well, whereupon the organic and aqueous phases separate.
