Sustainable Protein Alternatives: Exploring The Viability of Edible Insects in Crisis Settings

Edible insects are garnering attention as sustainable protein alternatives to address the nutritional challenges in crises. These scenarios, characterized by severe food insecurity and malnutrition, are frequently exacerbated by conflicts, natural disasters, and the COVID-19 pandemic, affecting vulnerable populations. This analysis examines the potential of edible insects, which are rich in protein, essential amino acids, and micronutrients, to address these issues. More than 2,000 insect species are considered edible, with the most frequently consumed being beetles, caterpillars, bees, wasps, ants, grasshoppers, locusts, and crickets. In East Africa, insect farming is expanding, with a focus on crickets, black soldier flies, and other species. However, the industry faces challenges related to feed expenses, pathogen and pest risks, and insufficient research. Enhancing the acceptability and nutritional quality of these foods can be achieved through value addition via processing techniques and incorporation into various food products. High-quality insect protein isolates for food applications can be obtained through protein extraction methods such as alkaline extraction and enzymatic hydrolysis. Promising avenues for increasing edible insect consumption include developing insect-based meat alternatives and fortifying baked goods with insect flour. Nevertheless, consumer acceptance remains a significant obstacle, necessitating additional research on the sensory properties and safety of insect-based foods. Overcoming these challenges requires increased funding, capacity building, and stakeholder coordination to expand the production and utilization of edible insects as a sustainable solution to nutrition challenges in crisis settings.
