Insects are part of the human diet in many parts of the world. Their nutritional value is widely recognized. Currently, most edible insects are harvested from the wild, although semi-domestication and indoor farming have increased insect availability and the sustainability of production. In traditional cultures, insects are processed in a number of ways (steaming, roasting, smoking, frying, stewing, and curing, among others) to improve their sensory and nutritional qualities as well as their shelf-life. In order to increase consumer interest in the West, various technologies have been developed that are aimed primarily at using insects as ingredients in a non-recognizable form, such as powders or flour. These technologies include drying (sun-drying, freeze-drying, oven-drying, fluidized bed drying, and microwave-drying) and new processing methods (ultrasound-assisted extraction, cold atmospheric pressure plasma, and dry fractionation) designed mainly for protein, fat, and/or chitin extraction. Insect-based ingredients are sold for the production of cookies, chocolates, tortilla-style chips, and other snacks. This review focuses on edible insect production, processing technologies, and commercialization using strategies ranging from traditional to novel as a sustainable approach for improving food security worldwide.
