Description

“Diacetyl, like butter, butter popcorn, or warm milk”

Certified soft drinks flavour standard used to train professional soft drink tasters to recognize and scale the intensity of diacetyl character.

Butanedione is produced by contaminant lactic acid bacteria during production of soft drinks. The compound can sometimes result from the activities of yeasts. Butanedione imparts a sweet, butter-like note to soft drinks and at higher levels will be perceived as an off-flavour.
