ABSTRACT:
This invention provides a process for the production of .delta.-decalactone by the microbial reduction of massoia lactone, characterized in that a bacterium having the ability to reduce massoia lactone is used as the microorganism. The .delta.-decalactone produced according to this process has a highly tastable, mild creamlike scent and flavor, and is hence suitable for use in flavor compositions.
