Original Abstract

This work focused on analysing the content of selected sterols and profile of fatty acids of edible insect species mealworm (Tenebrio molitor) mid superworm (Zophobas morio), which are expected to increase their usability in human nutrition. Sterols content was determined using capillary gas chromatography method. Cholesterol content was determined at 1335 mg/kg in dry matter (DM) for the mealworm, which was less than for superworm (3224 mg/kg DM). Other sterols analysed were stigmasterol and beta-sitosterol, which were once again higher in superworm (stigmasterol - 44 mg/kg DM and beta-sitosterol - 414 mg/kg DM) than in mealworm (stigmasterol - 18 mg/kg DM and beta-sitosterol - 171 mg/kg DM). From the nutritional point of view, the amount of cholecalciferol is also not negligible, which was 190 mu g/kg DM in mealworm and 199 mu g/kg DM in superworm. Atherogenic index (AI), thrombogenic index (TI), and cholesterol index (CSI) were calculated for both species and compared with the results of other authors. These indexes are often considered predictors of cardiovascular diseases. A potential benefit of both species could be the balanced proportion of sterols of animal and plant origin that could he nutritionally well-accessible and lower weight of dry matter necessary to consume to cover the daily dose of linoleic acid compared to dried beef.
