Product 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.

Food grade | Free from sensory impurities | Extensively tested | Safe to smell and taste.

IMPORTANCE

Diacetyl imparts a sweet, butter-like note. Its presence can be indicative of microbiological spoilage of soft drinks by lactic acid bacteria or by alcoholic yeasts.

ORIGINS

Diacetyl (2,3-butanedione) is produced by contaminant lactic acid bacteria (Lactobacillus, Pediococcus, Leuconostoc). Some yeasts produce a precursor of this compound which can give rise to 2,3-butanedione formation during product storage.

HOW TO TASTE

The best way to detect diacetyl flavour in soft drinks is as follows. Without covering the glass, swirl the sample to release the aroma. Take a single short sniff. Repeat as necessary.

CAS NUMBER

The CAS registry number of acetaldehyde is 431-03-8.
