dimethyl sulphide

75 µg per capsule

DMS, like sweetcorn or tomato sauce”

Certified soft drinks flavour standard used to train professional tasters to recognize and scale the intensity of DMS character. Dimethyl sulphide contaminates soft drinks through use of insufficiently-purified carbon dioxide for carbonation. It can also arise through bacterial spoilage of ingredients. It imparts a sulphury odour, reminscent of sweetcorn or tomato sauce.

Food grade | free from sensory impurities | extensively tested | safe to smell and taste.

Assessment
The best way to evaluate sulphury flavours from dimethyl sulphide (DMS) 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.
Amount of flavour per capsule
75 µg per capsule
Threshold
The flavour threshold of dimethyl sulphide in soft drinks is 25 µg / l.
Origins
DMS is a contaminant introduced to soft drinks through use of insufficiently-purified carbon dioxide. This flavour can also arise through bacterial spoilage of ingredients and additives.
Importance
Dimethyl sulphide is associated with sulphury and ‘muddy’ odours notes. It is an indicator of contamination of the carbon dioxide supply. DMS can also be associated with contamination of the water supply with faecal bacteria.
CAS registry number
The CAS registry number of dimethyl sulphide is 75-18-3.
Other names
  • DMS
  • dimethyl monosulfide
  • methylsulfanylmethane
  • methyl monosulfide
  • methane thiomethane
  • methyl sulfide
  • methyl thioether
  • methylsulfanylmethane
  • 2-thiapropane

Remarks
Other sulphur compounds may be found alongside dimethyl sulphide in contaminated carbon dioxide. Indole and skatole are often found in water in which DMS has been produced by bacteria. Fruity flavours arising from 2-pentanone may be present in water in which the DMS has been formed by algae.
