The gas monitoring equipment in breeding of edible insects
Chlumecký, Karel ; Skácel, Josef (referee) ; Adámek, Martin (advisor)
Bachelor’s thesis deals with monitoring of edible insects. The most monitured element will be dangerous gases. In the first part will be discussed the life cycle of edible insects and associated ecological consequences. Another part is description of measuring non-electric variables. This knowledge will be useful in design of breeding box in practical part of bachelor’s thesis. Design contains selections and description of used components and their locations on breeding box. Breeding box is managed by microcontroller ESP32 from Espressif family. Practical part contains first results of measuring and program for microcontroller. The results are in the form of a graph. Breeding box can be used for most terrarium animals.

Nutritional benefit of cricket flour
Šťastná, Martina ; Zemanová, Jana (referee) ; Němcová, Andrea (advisor)
Edible insects have been part of the diet of many countries across the world for several decades. It is becoming increasingly popular in the europian developed countries, mainly because of the content of nutritionally important substances. The theoretical part of the thesis deals with the characterization of edible insects in terms of nutritional benefits, explains the reasons and method of breeding edible insects. For the analysis of nutritionally active substances, flour of house cricket (Acheta domesticus) was used. A. domesticus belongs to the representatives of insects legalized from 1.1. 2018 on the EU market. Of the significantly nutritional substances, proteins, lipids, fatty acids, fiber and selected minerals were analyzed. In this study, optimalization of vertical electrophoresis SDS-PAGE was performed to determine protein fragment sizes. In the second part the influence of acricket flour addition protein bars was investigated by sensory analysis. In the experimental part that was found that cricket flour contains protein, lipids and fatty acids in significant amounts. It also contains important minerals for human health such as magnesium, potassium, iron or zinc. However, the sensory properties of protein bars for consumers were not very attractive.

Trendy ve využití hmyzí suroviny v potravinách
Polák, Daniel
This bachelor thesis deals with the use of edible insects material in the food industry. Around 2000 edible insect species have been recorded worldwide and are commonly consumed in Africa, Asia and Oceania. In recent years, edible insects have also become a major topic of discussion in the Western world. In the European Union, legislative steps have been taken to categorise certain species of the edible insects as food. On the European market, products made from the yellow mealworm, the house cricket, the migratory locust and the lesser mealworm can be found. These edible insects are a rich source of protein, fat, vitamins and minerals. It also contains the fibre chitin which is associated with lower digestibility of insect products and may also act as an allergen. Some nutritional substances may be subject to the development of innovative technologies. For example, proteins from the migratory anemone have the potential for the development of edible packaging or chitin fibre may be another alternative source to obtain chitosan.

Optimization of breeding of darkling beetles due to possible use in human nutrition
MAJEROVÁ, Tereza
This thesis was created to find a suitable substrate for feeding the larvae of the darkling beetle (Zophobas morio) intended for human consumption, as well as to find out if the larvae contain, among other substances, gluten. This species is very suitable for entomophagy for its breeding simplicity and nutritional composition especially rich in fats and proteins, similar to its relative, mealworm beetle (Tenebrio molitor). The topic of entomophagy is currently up-to-date due to the growth rate of the human population, whose needs are increasingly burdensome for the environment. At the same time, insect production is cheaper and more efficient than the production of the conventional meat (beef, pork, poultry) and also consumes less water. For the purpose of the experiment, 540 larvae were kept under the same conditions, divided into groups of 15 individuals with a total initial weight of 1g. 9 repetitions were made for each of the four selected substrates. The experiment lasted 3.5 months and during this time 8 measurements (weighing) were performed. The larvae feeding on substrates containing gluten were growing faster in the first half of the development, but there was no statistical difference between the final weight of the larvae on the different substrates, the average weight of one larva was between 0,7248 g and 0,8048 g. Laboratory analysis failed to detect the presence of gluten, the protein content ranged from 25 to 34%, the fat content was between 49 - 61%, these values are eventually compared with the results of other authors.
