Abstract

A process for flavouring foodstuffs includes incorporating therein a flavoring effective amount of at least one compound represented by R1-S-R2 wherein R1 and R2 represent (a) a hydrogen atom and a 1-(1-methoxycarbonyl)ethyl group or represent (b) a hydrogen atom and a 1-(1-propyloxycarbonyl)ethyl group. Foodstuffs and concentrates containing at least one of the R1-S-R2 compounds are provided.
