Abstract
With the surge in consumption of insects, the search continues to find ways to increase the popularity of insect-based products in the Western world. The black soldier fly larvae (BSFL), which is mainly utilized for animal feed, has great potential to provide a sustainable source of nutrients for human food. This review aims to discuss some of the key benefits and challenges of BSFL and their potential role as a food ingredient and/or product for human consumption. Few articles specifically discuss BSFL as a food source, therefore a comprehensive literature search strategy consisted of collecting and evaluating published data about BSFL as animal feed that could be relevant to its use in food. The hurdles that need to be overcome in order to introduce BSFL as a viable food option include safety concerns, technofunctional properties, nutritional aspects, consumer attitudes, and product applications for BSFL.
