The aim of this review was to identifythe key factors influencing consumer perception andacceptability of insect-based foods described in recentliterature. Even though sustainability factors are important, theyare seldom the main reasons influencing insect consumption.Instead, a complexity of emotional factors, such as disgust andneophobia, as well as familiar tastes, textures and contexts,were found to have a major influence. In addition, exposure andpositive tasting experiences have been identified as importantfactors for increasing acceptance. It could be concluded thatthere is a great complexity of different factors influencingconsumers’ perceptions and acceptability of insects as food.
