NIOSH also recommended a short-term exposure limit (STEL) for diacetyl of 25 ppb for a 15-minute time period. [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. 2 Add to List 2010 Jun;67(6):699-706.
