Volatile Sulphur Compounds in UHT Milk

Critical Reviews in Food Science and Nutrition, 2008
Several volatile sulphur compounds have been detected in raw and processed milk. These are hydrogen sulphide, methanethiol, carbonyl sulphide, dimethyl sulphide, carbon disulphide, dimethyl disulphide, dimethyl trisulphide, dimethyl sulphoxide, and dimethyl sulphone.

Oral Concentration of Volatile Sulphur Compounds in Stressed Rats

open access: yesStress, 2002
Stress has been identified as a halitosis-inducing factor. Halitosis may be measured by the determination of oral volatile sulphur compound levels (VSC). Since immobilization and swimming are two experimental protocols widely used to induce stress in laboratory animals, the aim of this work was to investigate the influence of stress on VSC in rats ...

Variation in oral volatile sulphur compound formation

Acta Odontologica Scandinavica, 2002
It has been suggested that the level of orally produced volatile sulphur compounds (VSCs) can be of use when monitoring oral malodour or in determining patients at risk of periodontal disease in longitudinal studies. It is not known, however, to what extent the level of VSC in mouth air is a stable, individual characteristic over time.The hypothesis to

Kinetics of the bio-oxidation of volatile reduced sulphur compounds in a biotrickling filter

open access: yesBioresource Technology, 2012
Mixtures of volatile reduced sulphur compounds (VRSCs) like hydrogen sulphide (H(2)S), methylmercaptan (MM), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS) are found in gaseous emissions of several industrial activities creating nuisance in the surroundings.

The Volatile Sulphur Compounds of Oysters

Journal of the Fisheries Research Board of Canada, 1964
The compound responsible for the characteristic odour of fresh Pacific oysters, Crassostrea gigas (Thunberg), has been identified as dimethyl sulphide [(CH3)2S], by the formation of mercury salts, and by infrared analysis and gas chromatography. The effect of bacterial action on the oysters has been observed and a number of the volatile organo-sulphur

The effect of cysteine on production of volatile sulphur compounds by cheese-ripening bacteria

International Journal of Food Microbiology, 2008
The effect of cysteine on the ability of smear cheese-ripening bacteria (Brevibacterium linens and Arthrobacter spp) to produce volatile sulphur compounds (VSC) from methionine was studied. These bacteria were cultivated in a synthetic medium supplemented with various cysteine concentrations with or without methionine.
