Diacetyl is a naturally occurring chemical found in low-concentration in apples, artichokes, beans, butter, coffee, dairy, fruits, honey, tobacco and vinegar. Diacetyl is also a natural byproduct from the conversion of glucose to ethanol by yeast during the fermentation process when crafting beer. Diacetyl is used by chemical manufacturers to give butter, margarine, shortening, oil sprays, flavorings and other food products a buttery taste. Diacetyl has been used in microwavable popcorn, snack foods, baked goods and, more recently, flavorings found in e-liquids for use in electronic cigarettes and vaping devices.
