[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. In addition to information on diacetyl, OSHA seeks information on acetoin, acetaldehyde, acetic acid, furfural, and other compounds present in food flavorings that may cause or contribute to flavoring-related lung disease. FEMA issued a new document, but the data is not substantially different than that provided in the 2011 draft criteria doc NIOSH submitted for comment.

Inhalation of butter A distinctive feature of diacetyl (and other vicinal diketones) is the long CC bond linking the carbonyl centers. Better it, it should be banned immediately, if there is some connection at the cellular level. However, previous investigations by the Centers for Disease Control and Prevention (CDC) show that inhaling diacetyl in other contexts has led to lung damage.

Occupational exposure to diacetyl has been associated with severe respiratory impairment and obliterative bronchiolitis, a serious lung disease that is irreversible. This bond distance is about 1.54, compared to 1.45 for the corresponding CC bond in 1,3-butadiene. As noted in the NIOSH Alert, Preventing Lung Disease in Workers Who Use or Make Flavorings, the flavorings industry has estimated that over a thousand flavoring ingredients have the potential to be respiratory hazards due to possible volatility and irritant properties (alpha, beta-unsaturated aldehydes and ketones, aliphatic aldehydes, aliphatic carboxylic acids, aliphatic amines, and aliphatic aromatic thiols and sulfides).
