Recent investigations indicate this method is adversely affected by humidity, resulting in an underestimation of true concentrations. Dr. Weissman is the Director of the NIOSH Division of Respiratory Disease Studies. This can decrease or block air movement through these airways. [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.

WebDiacetyl was first synthesized more than 80 years ago and can now be found in about 6,000 food products. NIOSH established recommended exposure limits (RELs) of 5 ppb for diacetyl and 9.3 ppb for 2,3-pentanedione as 8-hour time weighted averages (TWAs). It contains a number of useful recommendations and can be found on the internet at the following address: http://www.lni.wa.gov/Safety/REsearch/Files/DiacetylFactSheet.pdf.
