Abstract
This research investigates the integration of Tenebrio molitor larvae (yellow mealworm) as an alternative protein source in poultry feed, framed within circular economy principles. As global demand for sustainable animal protein rises, insect-based feed offers a strategic solution for waste valorization and resource efficiency in the 2025-2030 period. The study analyzes consumer target groups and factors influencing their willingness to consume insect-fed poultry, utilizing a direct survey of 100 respondents conducted at a food technology exhibition. Furthermore, a comparative economic analysis of five experimental groups reveals that while electricity and fixed costs remain stable, the inclusion of T. molitor increases production costs per kilogram meat by 8.30% to 25.75% compared to conventional feed. Results suggest that while the sensory qualities of the meat are well received - with 2.5 % and 5.0 % inclusion groups outperforming the control in taste tests - achieving market success depends on transparent communication to overcome food neophobia. Addressing cost-competitiveness is paramount for realizing the potential of insect-based circular food systems.
