Edible insects are a promising raw material used in the food industry for food production in terms of increasing their nutritional value. During rearing, qualitative parameters of mealworm larvae fed by wheat bran (OTR) and experimental diet (EX) were determined. Larvae of the EX variant showed a higher total weight and growth index (GI) (m = 1889.5 g; GI = 501.8) than larvae of the OTR variant (m = 1806.2; GI = 482.9). Larvae of the EX variant showed a higher intensity of red colour. The technological processing resulted in a decrease in the values of L*, a* and b* parameters in the larval variants. The chemical composition and colour parameters of technologically processed larvae depended mainly on the larval feed mixture, however the b* parameter values were significantly higher in the EX variant of larvae killed by boiling (p < 0.05).
