Booming the bugs: How can marketing help increase consumer acceptance of insect-based food in Western countries?

Edible insects could be a promising answer to the question of how to feed a growing human population with a healthier and more sustainable source of protein. Despite the increasing interest in entomophagy in food science and industry, however, consumer acceptance for insect-based food products remains low in Western countries. This systematic review provides a comprehensive and timely overview of studies relevant for researchers, practitioners and other stakeholders involved in the marketing of these products. Reviewing data from 45 selected studies, we focus on marketing measures tested for their influence on Western consumers' preference, acceptance, willingness to try, eat and/or buy insect-based food products. Organising the findings according to the 4Ps of the marketing mix framework, five main ways of enhancing the appeal and acceptance of insect-based food products are discussed: 1) developing product attributes that align with the specific preferences of target consumers; 2) a more subtle labelling of the presence of insects; 3) using value-added or competition-based pricing strategies; 4) making products consistently available in the marketplace; and 5) promoting products more effectively through advertising, tasting activities, and social influence. The heterogeneity we find among the studies, whether due to differences in the products researched, in sampling countries, or in data-collection methods, indicates key research gaps for future studies to address.
