Procedure

A process for preparing a peppermint oil containing a reduced menthofuran content, which comprises reacting the peppermint oil with about 0.5% to about 15% by weight maleic anhydride, based on the weight of peppermint oil to selectively form a menthofuran-maleic anhydride adduct without otherwise affecting the flavoring agent properties of the remaining peppermint oil constituents and recovering the peppermint oil having a reduced menthofuran content.
