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.
Chromatografická analýza rostlin a produktů spojených s výrobou absinthu a testování odpadů z výroby jako možného zdroje biopesticidů
BEDNÁŘ, Jan
This thesis deals with the analysis of herbs traditionally used for the absinth production: Pimpinella anisum, Foeniculum vulgare and Artemisia absinthium. The suitable GC-MS methods were developed and validated and they were used for the determination of the volatile substances content in essential oils and dried herbs which are available at the Czech market. Another aim of this study was to determine the content of t anethole and -thujone during the distillation of absinth in both laboratory and industrial scale. Finally, distillation residues were tested on Spodoptera litoralis larvae for potential pesticidal effects at VÚRV.
