The yeast then absorbs the diacetyl, and reduces the ketone groups to form acetoin and 2,3-butanediol. Those toxins can lead to inflammation, the build-up of plaques in the brain and, as a result, impaired cognitive function. In addition, laboratory studies document that diacetyl has toxic properties as a single component that parallel the effects of exposure to a butter flavoring mixture. 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). 5 [6], Diacetyl and acetoin are two compounds that give butter its characteristic taste.

Basic information on PFAS. The consumer needs to know when they buy a product whether or not it contains this dangerous ingredient. According to the Environmental Protection Agency (EPA), these chemicals might include perfluoroalkyl and polyfluoroalkyl substances (PFAS). Even if that item is labeled as being naturally seasoned it might still contain diacetyl. Even though the human health risk of diacetyl has actually been understood for decades there is no present requirement that a company indicate on a box or label, when a product includes diacetyl.

Diacetyl, a chemical used to give microwave popcorn its buttery flavor and aroma, is linked to severe and irreversible lung damage when inhaled in large amounts. The entire document can be seen here: https://www.cdc.gov/niosh/docs/2016-111/default.html The development of the NIOSH assessment, including the proposed REL, followed a standardized and documented process, including carefully considering stakeholder input as well as rigorous peer reviews, in its evaluation of the scientific evidence. Diacetyl is a prominent chemical ingredient in butter flavorings and is a component of the vapors coming from these and other flavorings. It also contains a draft Recommended Exposure Limit (REL) based upon a quantitative risk assessment. 4321, et While diacetyl can be found naturally in some foods, it is most common in processed food products that contain flavoring additives.
