Determination of Vicinal diketones (VDKs) in beer
VDKs (Vicinal Diketones) are metabolic products of yeasts which form in constant proportions during fermentation. These include diacetyl, which forms in the highest concentration.
It is important to monitor vicinal diketones levels during fermentation, as excessive VDKs production may be a sign of incorrect fermentation, bacterial or wild yeast infection. Furthermore, VDKs concentration plays an important role in the formation of flavour during the beer maturation time.
