They are used in a wide variety of products such as baked goods (cakes and cookies), confections (candy and chocolates), and snacks (potato or corn chips). Clark S. Diacetyl in foods: A review of safety and sensory characteristics. The final decision rests with the beer consumer. 2. Diacetyl exposure can cause permanent, severe, and potentially lethal lung disease in workers and consumers. This led to higher concentrations of PFAS in the blood serum of fast-food consumers and those who snacked on microwave popcorn, as compared with those who cooked their meals. The yeast then absorbs the diacetyl, and reduces the ketone groups to form acetoin and 2,3-butanediol. However, they are still manufactured in other countries and continue to appear in a number of consumer products that are imported into the United States. 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.
