The draft diacetyl /2,3-pentanedione criteria document has been referenced in several publications, including a recent Flavor and Extract Manufacturers Association (FEMA) publication on Respiratory Health and Safety in Flavor Manufacturing Workplace. Higher diacetyl content in products may lead to higher exposures, and thus greater risk to workers. NIOSH is not involved in food or food additive safety issues. All these are risk factors for early-stage Alzheimers disease. Dr. Kreiss is the Chief of the Field Studies Branch within the NIOSH Division of Respiratory Disease Studies. It is also possible to remove the diacetyl by adding more yeast after the end of fermentation.

This is scary and information which the public should be aware of. What is the difference between c-chart and u-chart? These same foods are linked to other serious health problems, making it that much more important to limit or remove them from a seniors diet. Because of this, manufacturers of artificial butter flavoring, margarines or similar oil-based products typically add diacetyl and acetoin (along with beta-carotene for the yellow color) to make the final product butter-flavored, because it would otherwise be relatively tasteless.
