Mealworm farming is gaining interest as a possible solution to the oversaturated meat supply chain, as an alternative source of protein. This is a more environmentally friendly activity that requires fewer inputs for production compared to meat. This review discusses the feasibility of mealworms as an ingredient for the production of novel foods, investigating crucial aspects, such as nutrition, technological capability, food safety, and consumer acceptance, among others. Tenebrio molitor larvae can be nutritionally comparable to meat, as they provide high-quality protein and other essential nutrients. Although the omega-6/omega-3 ratio exceeds the recommended limit (<5), certain strategies during larval breeding, including feeding, and cooking, may significantly reduce this gap. The use of mealworm flour in the food industry can provide apparently healthy, safe matrices with high protein content. However, inclusions above 10% often lead to technological and sensory deficiencies. Further experimentation is required to overcome these issues, which negatively impact consumer acceptance, and to promote social behavioral strategies to attract consumers toward insects. On the other hand, regulatory policies might play a crucial role in supporting this business, which is predicted to grow as technology develops and this activity aligns with a circular economy.
