A novel technology (Olfactoscan screening) was applied to screen for volatiles including saturated aldehydes that mask the perception of methional, an off-flavor commonly found in orange juice. For the screening experiment, methional odor pulses were generated by an olfactometer and

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
