Comparison of the content of volatile sulphur-containing compounds in Slovak beers by the SPME method.

Kvasný průmysl, 2008
A comparison of volatile sulphur-containing compounds in Slovak beers was performed. These compounds, due to their low sensory threshold, and powerful and often unpleasant characteristics, can cause off-odours even in trace amounts.

Correlation between microbial community and flavour formation in dry-cured squid analysed by next-generation sequencing and molecular sensory analysis

Food Chemistry: X, 2022
The sensory characteristics of dry-cured squid are closely related to its microbial community structure. To explore the relationship between microorganims and flavour formation, the microbial community and sensory characteristics of dry-cured squid at ...

Production of volatile and sulfur compounds by ten Saccharomyces cerevisiae strains inoculated in Trebbiano must

Frontiers in Microbiology, 2016
In wines, the presence of sulphur compounds is the resulting of several contributions among which yeast metabolism. The characterization of the starter Saccharomyces cerevisiae needs to be performed also taking into account this ability even if evaluated

Optimization of Determination of Dimethyl Sulfi de in Wort and Beer

Kvasný průmysl, 2017
Sulphur compounds present in barley, malt and beer are mostly non-volatile substances (amino acids, proteins, inorganic sulphates) from which volatile sensory active substances can be produced under certain conditions. The presence of these substances in

Sulphur Compounds: Comparison of Different Sorbent Tubes for Their Detection

Chemical Engineering Transactions, 2022
Different techniques have been developed for the analysis of gaseous sulphur pollutants, to maximize the analytical signals. In a complex matrix, such as odorous emissions, the detection of sulphur compounds can be critical in GC analysis, due to the ...

Effects of Hydrothermal Processing on Volatile and Fatty Acids Profile of Cowpeas (Vigna unguiculata), Chickpeas (Cicer arietinum) and Kidney Beans (Phaseolus vulgaris)

Molecules, 2022
Legumes are an economical source of protein, starch, dietary fibre, fatty acids, vitamins and minerals. However, they are not as fully utilised, due to volatile compounds contributing to their undesirable odour. The purpose of this work was to understand

Volatile sulphur compound measurement with OralChroma^TM: a methodological improvement [PDF]

Journal of Breath Research, 2015
The instrumental measurement of volatile sulphur compounds is a common practice to assess halitosis. One of the most widespread devices for that purpose is OralChroma(TM), a combination of a semiconductor gas sensor and a compact gas chromatograph (GC) system.

Volatile sulphur compounds composition of monovarietal white wines [PDF]

Food Chemistry, 2010
The sulphur compounds composition of wines produced experimentally from six white cultivars (Alvarinho, Loureiro, Trajadura, Pedernã, Azal Branco and Avesso) was evaluated during two consecutive vintages. Results show that wines could be differentiated according to their sulphur compounds content.
