Effect of used sweeteners on sensory properties of fruit drinks
 PRAYER, Radek
The object of the study was a sensory evaluation of used sweetners in beverages from selected fruits. Within the sensory analysis apple juice and also pear, apricot, cherry and blackcurrant nectar were used. These drinks were subsequently diluted at two concentrations with drinking water: 1) in a ratio of 50 % of the original beverage and 50 % of drinking water; 2) in a ratio of 25 % of the original beverage and 75% of drinking water. Each of the concentrations were then divided into groups which were sweetened with white sugar, cane sugar, aspartame, sucralose or rebaudioside A. The performed sensory analyses show that rebaudioside A would have great potential to replace the commonly used white sugar in apple juice. Sucralose would have this potential in pear and cherry drinks. However, the use of other sweeteners in other types of beverages is also not excluded, because to prove a preference for white sugar failed in most cases.

Stevioside and rebaudioside use in the food industry in the Czech Republic and the European Union
 PRAYER, Radek
The main objective of this work was a search process can use steviolglycosides in foodstuffs within the Czech Republic and the European Union in the period since 2000, focusing on legislation and non-food use. Based on journal articles and available legislative provisions, it is clear that Stevia is a plant with great potential to replace at least part of the current sweeteners. Stevia can also be used in cosmetics or in medicine because it contains substances that are beneficial to health. Legislation currently in force in the European Union and the Czech Republic permitted in food use steviolglycosides in high purity. Using Stevia plants or parts thereof, as food is not allowed.
