Xanthan - Gum produced from corn sugar. Diacetyl is produced during fermentation as a byproduct of valine synthesis , when yeast produces -acetolactate, which escapes the cell and is spontaneously decarboxylated into diacetyl. [13][14], Chronic industrial exposure to diacetyl fumes, such as in the microwave popcorn production industry, has been associated with bronchiolitis obliterans, a rare and life-threatening form of non-reversible obstructive lung disease in which the bronchioles (small airway branches) are compressed and narrowed by fibrosis (scar tissue) and/or inflammation. 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. Occupational Safety & Health Administration, Hubbs A., et al. It can also masquerade I find these studies of diacetyl and health risks shocking, and question if this is only the tip of the iceberg.
