Scalping of Light Volatile Sulfur Compounds by Wine Closures

Journal of Agricultural and Food Chemistry, 2012
Closures have an important influence on wine quality during aging in a bottle. Closures have a direct impact on oxygen exposure and on volatiles scavenging in wine. Model wine solution soaking assays of several types of closures (i.e., natural and technical cork stoppers, synthetic closures, screw caps) with two important wine volatile sulfur compounds

Volatile sulfur compounds in food flavors

C R C Critical Reviews in Food Technology, 1974
The volatile sulfur compounds are generally present in trace amounts in foods. These compounds possess a strong and powerful odor and contribute to both agreeable and disagreeable flavors of foods....

Characterization of volatile sulfur compound production by Solobacterium moorei

Archives of Oral Biology, 2012
Solobacterium moorei is a Gram positive bacterium that has been specifically associated with halitosis. The aim of this study was to characterize volatile sulfur compound (VSC) production by S. moorei.S. moorei was either grown or incubated in the presence of various supplements prior to determining VSC production with a Halimeter sulfide monitor.

Volatile metabolites in occupational exposure to organic sulfur compounds

Archives of Toxicology, 1993
Dimethyl sulfide in breath was determined by the gas chromatographic method in 14 persons exposed to organic reduced sulfur compounds in sulfate pulp mills. Dimethyl sulfide concentrations in breath (range 0.04-0.69 cm3/m3 were compared to the combined workplace concentrations of methyl mercaptan, dimethyl sulfide and dimethyl disulfide. This method of

Influence of anxiety on the production of oral volatile sulfur compounds

Life Sciences, 2006
Since many patients complain about halitosis without there being any clinical evidence of its cause, psychological symptoms have been pointed out as halitosis-inducing factors. The aim of this study was to evaluate the influence of anxiety on the production of volatile sulfur compounds (VSC).

Ammonia volatilization from compound nitrogen-sulfur fertilizers

1993
Co-granulated urea and ammonium sulfate (AS) offer the potential for supplying both nitrogen (N) and sulfur (S) in a form readily available for plant uptake. Possible effects of a partial substitution of urea by AS on urea hydrolysis and ammonia (NH3) volatilization were examined in laboratory experiments.

Nitrification Inhibition by Nitrapyrin and Volatile Sulfur Compounds

Soil Science Society of America Journal, 1985
Abstract Nitrification inhibitors can slow the rate of nitrification in soils and reduce nitrogen losses under some soil‐climatic conditions. Carbon disulfide (CS 2 ) and compounds which produce CS 2 have slowed nitrification in ...

Microbial Turn-over of Volatile Sulfur Compounds

1996
Biological production and consumption of sulfur gases include compounds such as H2S, methylsulfides (CH3SH, (CH3) 2S, (CH3S)2), methanesulfonate (CH3SO3H), sulfoxides (SO2), carbon disulfide (CS2) and carbonyl sulfide (COS). Only H2S, COS, SO2 and CH3SH are true gases under most environmental conditions, but other sulfur compounds, such as ...

Inhibition of nitrification in soils by volatile sulfur compounds

Soil Biology and Biochemistry, 1974
Abstract Carbon disulfide, dimethyl disulfide, methyl mercaptan, dimethyl sulfide, and hydrogen sulfide retard nitrification of ammonium in soils incubated in closed systems. The inhibitory effects of these volatile sulfur compounds on nitrification decrease in the order listed.
