Processing of selected species of edible insects for food purposes
Masár, Martin ; Lacina,, Lubor (referee) ; Svěrák, Tomáš (advisor)
Táto diplomová práca je zameraná na nutričné zhodnotenie vybraných práškov hmyzu zo svrčkov domových, z lariev múčiara obyčajného a potemníka stajňového a jedného potravinového produktu na báze hmyzu, ktorý bol tiež vyvinutý ako jeden z cieľov tejto práce. Okrem základných nutričných analýz boli použité aj ICP-OES pre zistenie obsahu minerálov a GC-FID pre zistenie zloženia mastných kyselín. Tiež bol stanovený obsah hrubej bielkoviny pomocou CHNSO analyzátora a stanovený obsah EAA. Pomocou PCA analýzy sa úspešne podarilo rozlíšiť vzorky jednotlivých hmyzích práškov, ktoré potvrdili rozmanitosť jednotlivých druhov hmyzu a vďaka projekcii do roviny hlavných komponent je možné vidieť, v ktorých nutričných parametroch sa najviac líšia. Bola tiež vykonaná senzorická analýza novo vyvinutého produktu na báze hmyzu s prídavkom prášku z potemníka stajňového v porovnaní s konkurenčnými produktmu. Súčasťou práce je aj rozsiahly spotrebiteľský prieskum na vzorke 2 019 účastníkov, týkajúci sa vnímania entomofágie v Českej republike a na Slovensku, ktorý sa uskutočnil online.

Device for measurement and regulation of edible insect breeding conditions
Dvorský, Adam ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This work focuses on the design and realization of a measuring and regulatory system for successful breeding of edible insects with a focus on the mealworm (Tenebrio molitor). For the correct setting of the system, the first part of the work is detected and described the general conditions of insect breeding. The description is mainly focused on the mealworm, its development and basic breeding conditions (temperature, humidity, etc.). This information is further used for the development of breeding equipment, the basic concept of which is further established at work. The device is controlled by espressif's ESP32 microcontroller. The work acquaints with its programming and the connection and programming of basic components for the proposed system. Experimental measurements verify the functionality of measurements and regulation in the breeding box. The regulation is accurate to tenths to hundredths of ° C.Last but not least, the design is compared with existing devices.

Edible insects and its position in nutrition
ŽALKOVSKÁ, Aneta
The aim of a bachelor's degree on "Edible insects and their position in nutrition" is to map the consumption of edible insects with surveys answered by respondents who have tasted or regularly eaten insects in the past. Two research questions had been identified: 1) What are the most common types of edible insects consumed in the Czech Republic, and; 2) What nutritional benefits they represent from the subjective point of view of insect consumers. The theoretical part of this bachelor's thesis is focused on getting acquainted with the concept of entomophagia and its position in human nutrition in other parts of the world and in our country. As well, there is listed nutritional composition of selected insect species and interesting points related to the way they are modified, used and consumed in selected countries. The practical part was made based on the evaluation of the results from the pollsurvey answers of the respondents who participated in the catering event called "Big Insect Evening" at the local restaurant "Club of Travelers" in Brno. Based on the evaluation of the survey it was found that entomophagia is currently only taken as a trend of modern gastronomy though not popular. It must be said that according to people's opinion, the interest in eating edible insects will gradually increase in the future: respondents said that after overcoming the psychic barrier, the taste of the insect was surprisingly positive, but they were not able to say with certainty whether they were not able to say with certainty whether they would start to search for it or rank it among their eating habits.

European legislation of novel food
Šálková, Lucie ; Grmelová, Nicole (advisor) ; Vavrečka, Jan (referee)
The thesis deals with legal aspects of novel food in EU, it brings also American point of view. Theoretical part of the paper is focused on the comparisn of the old legislation of novel food with new one, which will be applicable until 2018. Another point in the theoretical part is charasteristics of EFSA and FDA institutions. In the practical part specific examples of novel food and their characteristics are defined there. Last point of the practical part is based on judicature.
