Lactic acid bacteria were screened for methional production from 4‐methylthio‐2‐ketobutanoate. Only Lactococcus lactis IFPL730 produced high amounts of methional. It was demonstrated that production of this compound was an exclusively enzymatic reaction. The present work describes for the first time that L. lactis can convert enzymatically methionine to methional in a process mediated by aminotransferase and α‐ketoacid decarboxylase activities. The activity seems to be strain dependent.
