Abstract:
Minerals are important components of thousands of enzymes and other compounds in the body. Although the content of minerals in the human body is small, their importance is immense. Edible insects can provide many of these minerals in abundance, and are therefore thought to be a good source of micronutrients. This study dealt with the effect of a rearing temperature and feed on the mineral content and on the content of selected heavy metals in mealworm (Tenebrio molitor). Mealworm larvae were kept at temperatures of 15, 20 and 25 °C, and fed with wheat bran, lentil flour and a mixture of both. The types of feed for the experimental groups were chosen purposefully, considering the availability on site, price and especially the impact on the nutrition composition suitable for human. The concentrations of the most significant elements in terms of human nutrition concerns, that is zinc and copper, were determined with inductively coupled plasma mass spectrometry. The results showed that the normality condition was not achieved for Ca, Fe, P and Pb (p
