2-bromophenol

9.1 µg per capsule

Technical specification

Assessment
The best way to detect antiseptic taints in soft drinks caused by bromophenols 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
9.1 µg per capsule
Threshold
The flavour threshold of 2-bromophenol in soft drinks ranges from 70 to 230 ng/ l.
Origins
Bromophenols can taint product through ingredients, water or packaging. Associated with use of recycled wood and cardboard. Can also arise due to growth of Alicyclobacillus bacteria in ingredients.
Importance
2-Bromophenol imparts an unpleasant note, described by consumers as ‘chemical’ or ‘contaminated’. It is often associated with the presence of guaiacol when produced as a result of spoilage by bacteria.
CAS registry number
The CAS registry number for 2-bromophenol is 95-56-7.
Other names
  • bromophenol
  • o-bromophenol
  • ortho-bromophenol
Remarks

Technical specification

Assessment
The best way to detect chlorophenoiic taints 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
500 ng per capsule
Threshold
The flavour threshold of 2,6-dichlorophenol in soft drinks is 50 - 160 ng / l.
Origins
Chlorophenols can taint soft drinks and juices through ingredients, water or packaging materials. Antiseptic taints due to chlorophenols are especially associated with use of recycled wood and cardboard in packaging materials.
Importance
2,6-Dichlorophenol imparts an antiseptic, medicinal note to contaminated soft drinks. The taints is regarded by consumers as unpleasant and tainted even at low levels. Chlorophenols are produced through reactions involving phenolic compounds and free chlorine.
CAS registry number
The CAS registry number for 2,6-dichlorophenol is 87-65-0.
Other names
  • 1-hydroxy-2,6-dichlorobenzene
  • 2,6-DCP
  • 2,6-dichlorfenol
Remarks
Water pH is important in determining the rate of formation of chlorophenols. Chlorophenols can be produced by bacterial action. In such cases this is often linked to misuse of carbon filters. Accidental use of chlorinated water in product formulation can also give rise to chlorophenolic taints.

dimethyl sulphide

75 µg per capsule

Technical specification

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
  • thiobis(methane)
  • thiobismethane
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.

ferrous sulphate

5.4 mg per capsule

Technical specification

Assessment
The best way to detect metallic taints in soft drinks is as follows. Take a little sample into your mouth. Move it around with your tongue for a few seconds then swallow it. To confirm, rub a little onto the back of your hand and check for metallic odour.
Amount of flavour per capsule
5.4 mg per capsule
