The formation of volatile sulphur compounds in unclarified grape juice

2015
The evolution of the sulphur gases OCS, CS2 and DMS was monitored during the clarification of freshly harvested juices from Müller-Turgau and Riesling. Immediately after crushing OCS and CS2 levels began to increase, substantially favoured by high temperatures. When fermentation started concentrations decreased. DMS was found only in fermenting juices.

Pathways that produce volatile sulphur compounds from methionine in Oenococcus oeni

Journal of Applied Microbiology, 2008
Determination of pathways involved in synthesis of volatile sulphur compounds (VSC) from methionine by Oenococcus oeni isolated from wine.Production of VSC by O. oeni from methionine was investigated during bacterial cultures and in assays performed in the presence of resting cells or protein fractions. Cells of O.

Volatile Sulphur Compounds in UHT Milk

2009
Heating milk to high temperatures such as 140 ºC, as used in ultra high temperature (UHT) processing, causes physical and chemical changes in the milk. The production of a cooked flavour is a major change which reduces consumer acceptance of the UHT milk.

Isolation and determination of volatile organic sulphur compounds in aqueous solutions

Fresenius' Journal of Analytical Chemistry, 1991
A procedure has been worked out for isolation and determination of volatile organic sulphur compounds in water. These compounds are isolated from an aqueous sample by countercurrent thin-layer head-space (TLHS) technique. After isolation, the sulphur compounds are burned in a quartz tube and the combustion products (SO2/SO3 mixture) are absorbed by a ...

Lepidium spp. and Allium spp. as a source of volatile sulphur compounds

2017
Sulphur-containing plant metabolites include a variety of chemical structures, varying from primary metabolites such as sulphur-containing amino acids to secondary metabolites like, thiosulfinates, glucosinolates and others. In recent years, volatile sulphur compounds (VSCs) have been assigned important biological properties, including antioxidant ...
