Description
| - Cílem práce bylo zjistit základní nutriční hodnoty dvou druhů hmyzu cvrčka stepního Gryllus assimilis (nymph and adults) a moučných červů Tenebrio molitor (larvae), využívaného velmi často jako krmiva pro terarijní zvířata a využitelných rovněž jako zdroj výživy člověka v podmínkách chovů Czech Republic. U Gryllus assimilis byl zjištěn průměrný obsah (in g/kg) dry matter 327.53 -- 338.98, crude protein 589.77 -- 593.47, fat 339.81 -- 345.50, chitin 19,42 - 19,68 g, ash 41,92 - 42,98 g, and brutto energy 24,308 do 24,614 MJ/kg. U Tenebrio molitor ve stejném pořadí (in g/kg) 286.15 -- 294.12, 468.48 -- 471.20, 369.21 -- 375.70, 18,39 - 19,43 g, 38,69 - 39,46 g, and 26.619 -- 26.995 MJ/kg. Vysokým hodnotám obsahu crude protein and fat také odpovídá vysoký obsah brutto energie. Bude potřeba další sledování pro vyjasnění možnosti cíleného využití těchto druhů hmyzu jako kvalitního zdroje potravin člověka. (cs)
- The aim of this work was to obtain basic nutrition value of two species of insects: field cricket (Gryllus assimilis - nymphs and adults) and mealworms (Tenebrio molitor - larvae), which are used as a food for pets in the Czech Republic, and which could be used as a source of food for man and farm animals as well. In Gryllus assimilis the average content detected was (in g/kg) dry matter 327.53 -- 338.98, crude protein 589.77 -- 593.47, fat 339.81 -- 345.50, chitin 19,42 - 19,68, ash 41,92 - 42,98, and brutto energy 24,308 - 24,614 MJ/kg. In Tenebrio molitor in the same order (in g/kg) 286.15 -- 294.12, 468.48 -- 471.20, 369.21 -- 375.70, 18,39 - 19,43, 38,69 - 39,46, and 26.619 -- 26.995 MJ/kg. High values of crude protein and fat are followed with high content of brutto energy. Further testing is necessary to clarify the possibility of utilisation of this two species of insects as a high quality of food resource for men.
