Consumer acceptance of edible insects and design interventions as adoption strategy

Edible insects are regarded as one of the most sustainable animal protein sources for human consumption, but for western people insects are a rather unusual food ingredient. In the media, however, insect consumption is gaining increasing attention and people are starting to acknowledge insects as a potential source of protein. The eating of insects, ‘entomophagy’, is bringing new insect food companies, ‘ento-preneurs’ to the market, yet current research is still insufficient and relatively fragmented to support the commercialization of insect-based food products. Therefore, more systematic research approaches are needed in this area. This review article introduces the benefits and challenges of insect-eating, discusses the factors that are known to influence consumer acceptance, and categorizes factors including adoption strategies into a framework that can be applied in future consumer studies on entomophagy. In addition, the article introduces three distinctive examples of design interventions to illustrate how design can contribute as a strategy to support the general adoption of insect foods by western consumers.
