diacetyl

Real-time measurement of diacetyl in beer Real-time measurement of diacetyl in beerThe flavor of beer is strongly influenced by the presence of diacetyl and 2,3-pentanedione. Owlstone's Lonestar analyzer can detect and measure levels of these two vicinal diketones (VDKs) in minutes, right on the brewery floor. Offering detection down to 30ppb (parts per billion) and the ability to measure total diketones or free diacetyl, the instrument is ideal for early fermentation monitoring and finished product quality assurance.
Detecting diacetyl vapor in the workplace Detecting diacetyl vapor in the workplaceThe Owlstone Chemical Agent Monitor (OCAM) detects diacetyl, a common industrial chemical that is used in foodstuffs such as microwave popcorn as a synthetic butter flavor. Inhalation of diacetyl has been shown to cause bronchiolitis obliterans (AKA popcorn lung or popcorn workers lung), a potentially fatal disease in which the bronchioles are narrowed by scar tissue and inflammation.
