Hodnocení kvality bylinných sirupů
Hrabiecová, Vendula
The thesis deals with a production of atypical formula of herbal syrups. The theoretical part describes ingredients for the syrups production, ingredients they contain, techno-logical procedure of the production and legislative requirements for the syrups produc-tion. In the practical part, two syrups were produced according to their own formula using three different sweeteners. The samples were sensory evaluated and using Statis-tica 14 and Microsoft Excel software. The samples were evaluated by two groups of students. The first group consist-ed of 47 students who were not experienced evaluators. A 5-point scale was prepared for them. The second group consisted of 10 students who were experienced evaluators. An unstructured 100 mm hedonic and intensity scale was prepared for them. The samples were evaluated based on preference of the sweeteners and herbal formula. The first group of evaluators (n = 47) preferred cane sugar as a sweetener in syrups. Based on the preference of the herbal formula, the results of both samples were equal. The second group (n = 10) preferred beet sugar in the first syrup and cane sugar in the second one. Based on the popularity of the composition of the samples, the first formula was chosen as having a higher potential for industrial production.

Havlíková, Jitka
In the Czech Republic, caraway (Carum carvi L.) is one of the most cultivated LAKR crops. In the last two years there has been a significant increase in growing areas. In 2017 and 2018, caraway was grown at 4 125 ha and 4 685 ha, which is the highest cultivation in the last six years. Average caraway yields in the Czech Republic are based on production and its quantity are around 0,86 t.ha-1. In the case of the addressed enterprises, the total direct costs were averagely ranged between 17 384-25 801 CZK.ha-1. From the years under review, cost profitability was negative only in 2018, namely for Business No. 2 (-32 %) and Business No. 3 (-20 %). In contrast, profitability of Business No. 1 was beneficial in all years under review. In the monitored enterprises the price of cumin seeds per ton in the period 2016-2018 fluctuated from 20 000 to 65 000 CZK. The results show that it is an attractive crop from the group of medicinal, aromatic and spicy herbs and it is confirmed that caraway is a suitable market crop that requires ongoing attention from a marketing perspective.

Návrh mechanizačního zajištění pro pěstování a sklizeň vybraného druhu léčivých a kořeninových rostlin (LAKR)
Opluštilová, Dagmar
In the thesis was elaborated an overview of the main operations related to the cultivation of the MASP. A model agrotechnical procedure was developed for the cultivation of two selected species MASP - peppermint (Mentha x piperita) and marigold (Calendula officinalis). In addition, machine operating costs, material costs and manual operations were determined. From these data, the total cost of the crop was calculated in CZK.ha-1 and CZK.t-1. Comparison with similar calculations has shown that the results are real and can be used in practice.
