The artificial butter flavouring 2,3-pentanedione, used to provide butter taste and aroma in microwave popcorn is an ‘inhalation hazard’ that may cause severe lung disease in food industry workers, warns new research.
EU regulators and processors say they are examining the use of diacetyl for foods, following reports of hundreds of US workers falling ill from a deadly lung disease linked to the inhalation of the popcorn flavouring chemical.
Flavor manufacturers and flavored-food producers need to develop a
timely, effective response to identify and reduce cases of lung
disease in workers exposed to flavors such as diacetyl, said the
CDC in a report last week.
