insects have been used as food due to their availability and easiness in
raising that is much less burdensome for environment than animal husbandry
breeding. Mealworm (Tenebrio molitor L.) is a store-pest of which larvae are consumed by people. The aim of the work
was to determine the nutritional value of larvae of mealworm (Tenebrio molitor L.). The material was a
three-month-old mealworm larva 25 -30 mmin length. Larvae were boiled for 3 min and next dried in 60℃. Contents of water, ash,
minerals, protein, fat and fat acids profile have been determined. Fresh larvae
contained 56% of water, 18% of total protein, 22% of total fat and 1.55% of
ash. High contents of minerals were found in the larvae: magnesium (87.5
mg/100g), zinc (4.2 mg/100g), iron (3.8 mg/100g), copper (0.78 mg/100g) and
manganese (0.44 mg/100g). The proportion of n-6/n-3 fatty acids was very
advantageous and amounted to 6.76. Larvae powder contained twice higher content
of protein, fat, ash and minerals. Larva of mealworm is a valuable source of
nutrients in amounts more profitable for human organism than traditional meat
food. Powdered larva is a high-grade product to be applied as a supplement to
