Substances present in cumin oils
Suchánková, Renáta ; Boško, Rastislav (referee) ; Svoboda, Zdeněk (advisor)
The bachelor thesis is devoted to important substances in caraway oil. The determination of substances was performed in the laboratories of the Brno Institute of Brewing and Malting, a.s. It is divided into theoretical and experimental part with results and their discussion. The theoretical part describes caraway (Carum carvi), its use and composition of caraway oil, including the possibility of its use. The practical part deals with the identification and determination of content substances in caraway essential oils by the method of gas chromatography and mass spectrophotometry (GC-MS). It also includes a comparison of the content of different caraway essential oils.

Koření z čeledi miříkovitých a jejich využití v potravinářském průmyslu
Halodová, Tereza
The diploma thesis "Spices of the Apiaceae Family and Their Use in the Food Processing Industry" focuses on the characteristics of medicinal, aromatic, and spice herbs. The the-sis examines the legislation related to spices, plant substances, and their use in the food processing industry, particularly in the production of essential oils. The thesis also describes the methods of essential oil extraction and the norms for determining their con-tent. The thesis provides a detailed description of the Apiaceae family, which includes significant plant species used as spices. The practical part of the thesis includes a compa-rison and analysis of specific spices from the Apiaceae family, such as Anise, Fennel, Caraway, Dill, and Coriander. The content of essential oils in these spices was determined using the steam distillation method (based on Český lékopis 2017). Samples of the spices were obtained from four different manufacturers. The discovered content of essential oils ranged from 0.66 ml/100 g to 5.26 ml/100 g.

Kmín kořenný (Carum carvi L.) jako agrokomodita
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.

Studie nákladovosti pěstování kmínu kořenného (Carum carvi L.)
Venclík, Radim
The aim of this thesis was explanation of growing caraway seed in the Czech Republic, based on available information gained from Ministry of Agriculture. Growers were asked for data regarding yields, prices and costs. Data were gained from four grower organizations, settled in diferent production areas: beet, potatos and corn. Growers farm different areas, between 640 and 3900 hectares. Caraway seed is growed on areas between 10 and 100 hectares. Variable costs differed substantially between 13 044 and 30 671 ha-1. Average yield of caraway seed achenes was 1,05 t.ha-1, oscilated between 0,995 t.ha-1 and 1,18 t.ha-1. The lowest yield gained the cropper growing winter kind of caraway - 0,955 t.ha-1. Price per tonne oscilated between 23 100,- and 50 133,- Czech crown. On condition that all growers obey recomended procedures it is clear, that caraway growing require continuous attention regarding marketing.

Hodnocení technologických postupů při pěstování kmínu kořenného s důrazem na sklizňový proces
Komárek, Vojtěch
This diploma thesis Evaluation of technological processes in the cultivation of caraway with an emphasis on the harvesting proces is focused on current situation and importance of caraway growing in Czech republic and in the world, on basic growth factors and work operations (mostly related to harvest) of common caraway. Main part is based on evaluation of two model technological processes. In first process were expenses of total 504,50 Kč.ha-1, in the second process were expenses bigger - 10 618 Kč.ha-1. Furthermore, this thesis was focused on enumerating the harvesting losses. For the purpose of comparability and objectification of the enumeration, two different methods of evaluation were used. By using the first method, 25,81 % losses were measured. Second method provided value of 22,09 %.

Variabilita obsahu silic kmínu kořenného ( Carum carvi,L.)
Urbánek, Jiří
The aim of the thesis was to prove the variability of the essence content by 36 evaluated samples (tribes) from the chosen new selection of caraway (Carum carvi L.). Caraway, its morphology, origin and spread was described in the literary part. It is followed by the summary of its most important use, its cultivating technology and the state of health was also described shortly. Next chapter devoted to the selection of apiaceae species with a view to caraway. Last two chapters describe plant essences and the content matters of caraway. The practical part gives an idea of individual samples (tribes), then the distillation with steam for finding of essence content and gas chromatography, which the analysis of limonene and carvone content was done, was described. The samples (tribes) number 25, 27, 34, 35 and 3 were evaluated as the best for the next selection from the standpoint of essence content and they had the right proportion of carvone to limonene.

Uplatnění mechanizačních prostředků při pěstování LAKR
Komárek, Vojtěch
The bachelor's work concern with mechanization machines used in production of medical plants. In work is possible technological procedure also included. All costs in production of caraway calculated on 16 760,50 Kč.ha-1. The most expensive is tillage, which costs 3 312,30 Kč.ha-1. Wery expensive is also fertilization, which costs 2 924,20 Kč.ha-1. The cheapest is the seedbed treatment, which costs 627,20 Kč.ha-1. Economic analysis and overal profitability of the crop.
