The Master thesis was made at Department of Post-Harvest Technology of Horticulture Faculty of Mendel University in Brno in 2012/2014.The thesis is devided into the two parts, theoretical and experimental part. First of all I classified and described beverages and carbohydrates which is the theoretical part of the thesis. Next chapters describe individual form of carbohydrates, natural and artificial as well which occur in beverages. Apart of this, I also introduced its properties, occurrence, importance and possible methods of analysis.A great deal of attention of this thesis is given to the experimental part which is concentrated on speed of decomposition of sucrose in different pH, thus influence of action of citric acid and oxalic acid, which were mixed up in concentrations 1 and 5 %. The decomposition was also observed in fruit juices.The methods used for subsequent determination of carbohydrates were method of Luffa-Schoorla and enzymatic determination of carbohydrates with using of set K-SUFRG Megazyme.Efficiently operated inversion acids, mainly oxalic acid.
