A process is provided for preparing an aroma product containing a high concentration of .alpha.-acetolactic acid, a precursor of the flavour component diacetyl, by subjecting at least one food product constituent to lactic acid bacteria which are in their stationary growth phase, particularly to a cell-free extract or cell lysate of lactic acid bacteria. The food product constituent can be citric acid, lactic acid and especially pyruvic acid or mixtures thereof. The pyruvic acid can be obtained by culturing a bacterium of the genus Propionibacterium, e.g. Propionibacterium freudenreichii. Suitable lactic acid bacteria include Lactococcus lactis, particularly subspecies lactis and its biovar diacetilactis, and Leuconostoc cremoris. The aroma product can be used for flavouring foodstuffs, for example by mixing it with pre-dried food materials.
