Review of Coconut Extra Flavor-TFA:

As the title implies anything with acetoin or diacetyl just takes a cautious hand. As long as your whole mix isn't composed of the funk it's all good in the hood. Don't be scared to use any of the fabulous flavors that may have a small % of "the funk" as I call it. They can really make all the difference in a mix and are by far nothing to fret over, especially in such a low percentage! The media simply blew something small out of proportion like it always tends to do. So again, be mindful; don't be scared! 

PS: the only case of "popcorn lung" that the media had knowledge of and based its harsh soap-boxing on was a 20yr employee at a popcorn factory who inhaled butter dust all day at work. So let's demonize an entire realm of unrelated products. Simply ridiculous!
