The culprit appears to be a compound known as diacetyl, which sort of gives you that buttery flavoring.
A new study shows that exposure to a chemical called diacetyl, a component of artificial butter flav ...
They grow best at moderate temperatures, well below the typical temperature of yogurt fermentation; they’re only moderate acid-producers, so the milks and creams they ferment never get extremely sour; and certain strains have the ability to convert a minor milk component, citrate, into a warmly aromatic compound called diacetyl that miraculously complements the flavor of butterfat.
It might be said semisynthetic or synthetic drugs such as diacetyl - that so does any good general practitioner.
I just found out that someone I know has popcorn lung, an irreversible lung disease caused by inhaling the buttery aroma of microwave popcorn, or specifically diacetyl, the chemical used to produce the buttery taste in the absence of actual butter.
Exposure to what the Occupational Safety and Health Administration terms "volatile butter-flavoring ingredients" (the chemical is diacetyl, currently being phased out of popcorn production.)
On March 16, the Occupational Safety and Health Administration (OSHA) announced it was moving to protect workers from a serious lung disease caused by diacetyl, the artificial butter flavoring added to popcorn and other food products.
In recent years, hundreds of workers in plants where diacetyl is produced or applied to food have developed the rare and sometimes fatal disease, bronchiolitis obliterans, also known as "popcorn lung."
The three companies that sell Orville Redenbacher, Act II, Pop Secret and Jolly Time microwave popcorn are planning to revamp their microwave popcorn formulations to remove diacetyl, which was been linked to cases of bronchiolitis obliterans, a rare life-threatening disease often called popcorn lung, the Associated Press reported on Wednesday.
Assemblywoman Sally Lieber (D) has introduced a bill to ban diacetyl use by 2010.
