There’s no better snack for movie night at home than a bucket of buttery popcorn. But you may think twice about the microwave stuff after we tell you about and ingredient it contains, diacetyl, and the trouble it has caused.
What is it?
Diacetyl was first synthesized more than 80 years ago and can now be found in about 6,000 food products. It’s used as a preservative in unsalted butter to lengthen shelf life, but higher amounts are added to butter-flavored products like microwave popcorn, cooking oils and sprays and margarine.
