dimethyl trisulphide

520 ng per capsule

Onion, like stagnant water or decaying vegetation”

Certified soft drinks flavour standard used to train professional tasters to recognize and scale the intensity of onion character. Dimethyl trisulphide contaminates soft drinks through use of insufficiently-purified carbon dioxide gas for carbonation. It can also arise through microbiological spoilage, and - sometimes - through non-microbiological chemical reactions. It imparts an unpleasant swampy odour, reminscent of onions, stagnant water or decaying vegetation.

Assessment
The best way to evaluate onion character imparted to soft drinks by dimethyl trisulphide (DMTS) is as follows. Cover the sample with your hand and swirl the glass to release the aroma. Remove your hand and take a single long sniff. Repeat as necessary.
Amount of flavour per capsule
520 ng per capsule
Threshold
The flavour threshold of dimethyl trisulphide in soft drinks is 170 ng / l.
Origins
Dimethyl trisulphide is a contaminant introduced into carbonated soft drinks through use of insufficiently-purified carbon dioxide. DMTS can also arise through microbiological spoilage and to a limited extent through non-microbiological chemical reactions.
Importance
DMTS imparts an unpleasant ‘swampy’ odour to water and to soft drinks made with such water. The intensity of the odour is increased in the presence of other sulphur compounds.
CAS registry number
The CAS registry number for dimethyl trisulphide is 3658-80-8.
