Abstract
Rising global population and sustainable protein demand have sparked interest in unique food sources. Entomophagy, or insect consumption, presents a solution and Scarab beetles, part of the Scarabaeidae family, offer a novel food option. The comprehensive review underscores their potential as human food, with strong nutrition, low environmental impact, and the ability to ease strain on conventional agriculture. Nutritional analysis reveals rich protein content, essential amino acids, vitamins, and minerals. Scarab beetles’ beneficial fatty acid profile and healthy fats position them as a superior protein source to traditional livestock. Scarabaeidae excel in feed conversion, emit fewer greenhouse gases, and require minimal land, establishing them as an ecologically sustainable protein source. Cultural attitudes towards insect consumption vary; history exists in some regions while skepticism prevails in others. Highlighting nutritional advantages, organizing outreach, and introducing processed scarab products could enhance acceptance. The review addresses challenges including mass rearing, processing, allergens, and toxins. Evolving insect-based food regulations require cautious consideration. Success depends on multidisciplinary efforts including nutrition, environmental sustainability, cultural openness, and regulatory alignment. Continued research and collaboration are essential to fully unlock Scarabaeidae’s potential as a sustainable, nutritious food source for our growing global population.
Abstract
As the global population continues to grow, traditional protein sources like meat and fish are becoming increasingly unsustainable due to their environmental impact. Edible insects, on the other hand, are highly nutritious, require minimal resources to produce, and emit significantly fewer greenhouse gases than traditional livestock. Lepidoptera, one of the most diverse insect orders, contains some popular edible species that have been consumed traditionally for centuries across the globe. Based on this review, about 24 families with a total of about 350 edible lepidopteran species were recorded. They are often praised for their excellent nutritional value, such as having high protein and healthy fat content. Edible lepidopterans also contain minerals, essential amino acids, and vitamins, making them a nutritious addition to a balanced diet. They also contain bioactive compounds which have various nutraceutical and pharmaceutical properties. Furthermore, some edible lepidopterans can be farmed and require minimal space and resources. However, there are significant challenges associated with their use as food. One of the primary challenges is the lack of regulations governing their production and distribution, which creates uncertainty for consumers and businesses alike. Consumer acceptance is also a significant barrier to the widespread adoption of insects as food. To overcome these challenges, there is a need for clear regulations that ensure the safety and quality of insect-based products. Furthermore, it is important to raise awareness about the nutritional and environmental benefits of edible insects as sustainable food for the future to promote their acceptance among consumers.
