These Lorann Flavors MAY contain Diacetyl (a flavor that is used to create a butter taste). Diacetyl is safe to ingest, but not safe for inhalation because it causes ‘popcorn lung, aslo known as Bronchiolitis Obliterans. **Update, I have talked to Lorann’s about this and they have said that NONE of their flavors (even the butter flavorers) have ANY DIACETYL. That said, SOME of their flavors do contain Acetoin/Acetyl Propionyl, which can catalyze into Diacetyl, due to the molecular structure being so similar. So in truth, their flavors may contain trace amounts of diacetyl.
