Global review of consumer preferences and willingness to pay for edible insects and derived products

The rising global demand for protein, driven by population growth, urbanization, economic development, and climate change, underscores the need for sustainable alternative protein sources. Edible insects have emerged as a viable solution to enhance foodfeed and nutritional security while contributing to waste management. This study reviews 128 peer-reviewed publications to assess consumer preferences and willingness to pay (WTP) for edible insects and their derivatives. Findings reveal that studies predominantly focus on Europe and insect-based foods, with limited research on insect-based feeds and derived products. Consumers in Africa, Asia, and Latin America show higher acceptance of insect-based food compared to those in Western nations, where psychological barriers such as neophobia, disgust, and limited awareness hinder adoption. WTP for insect-based foods varies, with some consumers willing to pay a premium while others expect lower prices than conventional options. Integrating edible insects into sustainable food and feed ssytems requires public education, innovative marketing, and scaling up production. • Global protein demand drives focus on edible insects for sustainable solutions. • 79% of reviewed studies focus on Europe, with insect-based foods dominating research. • WTP for insect-based food ranges from premiums to discount expectations. • Acceptance of insect-based foods is higher in Africa, Asia, and Latin America. • Awareness, neophobia, disgust, and knowledge gaps affect edible insect acceptance.
