Cultured cream, cultured butter, and cultured buttermilk owe their tart flavour to lactic acid bacteria and their buttery aroma and taste to diacetyl. Has diacetyl been found in any food flavoring involving the milk product industry, such as yogurt/flavorings? Unfortunately, the foods that hamper memory are common staples in the American diet. [10], Diacetyl is produced during fermentation as a byproduct of valine synthesis, when yeast produces -acetolactate, which escapes the cell and is spontaneously decarboxylated into diacetyl. [8] People nearby may be exposed to it in the exhaled aerosol at levels near the limit set for occupational exposure. The challenge is that there may be a diacetyl precursor in a sample of beer that you cant taste or smell: acetolactate. I.
