Látky vázající oxid siřičitý ve víně
Musil Petrjánošová, Martina
This bachelor thesis deals with the description of the characteristics of sulfur dioxide, its properties, influence on organoleptic properties and its use with respect to human health. In addition to sulfur dioxide, the work also deals with substances that bind it in wine, such as acetaldehyde, ketonic acids - pyruvic acid and acid 2-oxoglutar et al. Describes the effect of sulfur on the formation of these compounds. At the end of the thesis, the effects of sulfur dioxide on human health and legislation, from which the limits for its use and labeling are based, are presented.
Vliv síření vína na vznik sloučenin vázajících oxid siřičitý ve víně
Sikora, Jakub
This thesis is concerned with the formation of carbonyl compounds in wine, depending on the spread of wine. Therefore examines what influences the spread of musts and wines on the formation of carbonyl compounds. Discusses the characteristics and forms of sulfur dioxide. Further detail the carbonyl compounds which bind just with sulfur dioxide. In this work it was found that the influence of the spread of the wine has no great influence formation of carbonyl compounds. On the contrary, it was confirmed that the initial SO2 concentration in the must greatly affects the formation of acetaldehyde, which binds sulfur dioxide. Furthermore ratified the greater influence on the formation of carbonyl compounds, the activity of microorganisms in the wine than different concentrations of SO2.
