“…In light of the predicted increase in the world population by 2050 and the growing demand for high-quality protein sources for food and feed production, insect culture deserves special attention [1][2][3]. In fact, insects show a high protein and fat content, they can grow on organic by-products, their rearing is characterized by low environmental impact [4][5][6] as they produce low greenhouse gases and ammonia emissions [1,7,8], and they show low water and space requirements [5].…”

“…It has been demonstrated that larvae of mealworm (Tenebrio molitor, Coleoptera Tenebrionidae) reared on olive fruits processing by-products can accumulate Pb and Hg [24], whereas Biancarosa et al (2018) [25] evidenced that HI grown on seaweed-enriched media accumulated significant amounts of PTEs such as Cd, Pb, and Hg. However, knowledge on chemical hazards associated to insects as potential ingredients for feed and food is scarce [9], but the interest about this topic is increasing [2,3,6,12,26,27]. Most studies used artificially-contaminated growth substrates to investigate the potential accumulation of PTEs in insects [28][29][30][31], and specifically in HI [20,[32][33][34].…”

Black soldier fly (Hermetia illucens, HI, Diptera, Stratiomydae) has great potential as a food and feed ingredient in the European Union (EU). The production of insects as livestock feed or as food ingredients requires strict monitoring of the content of potentially toxic elements (PTEs) in the growth substrate, to meet the security requirements. This study aims to investigate the presence of PTEs, like cadmium, lead, mercury, arsenic, and nickel, in HI prepupae and in their growth substrates based on coffee roasting by-product and microalgae Schizochytrium sp. and Isochrysis sp. Analyses were carried out via graphite furnace atomic absorption spectrophotometry for Cd, Pb, Ni, and As, and via Direct Mercury Analyzer for Hg. All element concentrations found in growth substrates were below the legal limit of undesirable substances in animal feed (2002/32/EC). Elements concentrations in HI prepupae were in the range (mg kg−1 wet weight) of 0.072 to 0.084 for Cd, 0.018 to 0.026 for Pb, 0.010 to 0.032 for Hg, 0.036 to 0.047 for As, and 0.18 to 0.76 for Ni. Even if HI prepupae accumulated Cd, Pb, and Hg, our results indicated that the risk of exposure to PTEs from HI prepupae consumption is relatively low and in compliance with EU regulations.

“…The United Nations Food and Agricultural Organization, among others, has proposed that edible insects could provide an alternative source to support efforts to combat global food insecurity [20][21][22]. Edible insects are increasingly considered a practical, nutrient-dense protein source with relatively low environmental demands [23][24][25].…”

Comparison of cricket diet with peanut-based and milk-based diets in the recovery from protein malnutrition in mice and the impact on growth, metabolism and immune function

Some evidence suggests that edible insects could be used to treat malnutrition following protein deficiency. However, additional studies are needed to better assess the potential of edible insects as a therapeutic food supplement and their long-term impact on recovery from malnutrition. The goals of this study were to investigate the effectiveness of a cricketbased diet in recovery from protein-malnutrition in early life, and to compare cricket protein to more traditional sources used for food fortification and supplementation. Protein-malnutrition was induced by administration of an isocaloric hypoprotein diet (5% protein calories) in young male mice for two weeks during puberty, followed by a six-week recovery period using a cricket-, peanut-or milk-based diet. We examined the impact of protein-malnutrition and subsequent recovery on body weight, growth and select biomarkers of inflammation and metabolism. Protein-malnutrition resulted in growth retardation, downregulation of inflammatory markers in spleen tissue, decreased levels of serum triglycerides, and elevated serum levels of leptin and adiponectin. The cricket-based diet performed equally well as the peanut-and milk-based diets in body weight recovery, but there were differences in immune and metabolic markers among the different recovery diets. Results suggest edible crickets may provide an alternative nutrient-dense protein source with relatively low environmental demands for combating the effects of early-life malnutrition compared to more traditional supplementation and fortification sources. Additional investigations are needed to examine the short and long term impacts of different recovery diets on metabolism and immune function.

“…This considerable attention on insects originated from their advantages of being abundant and environmentally friendly; they constitute more than 80% of all living organisms on the earth and require less land and water in comparison with livestock [2][3][4]. Notably, insects have advantages regarding nutritional value; particularly, insects have high-quality proteins and are composed of 50%-70% total protein compared with plant and meat proteins [5][6][7][8]. Incidentally, insects have great potential to become one of the most promising protein sources, owing to their ability to solve the global problem of protein production regarding nutrition, environment, and economic value [7,9].…”

Incidentally, insects have great potential to become one of the most promising protein sources, owing to their ability to solve the global problem of protein production regarding nutrition, environment, and economic value [7,9]. Apart from their nutritional roles, insect proteins have various pharmacological properties, such as antioxidant activity, anticancer activity, and a protective effect against atherosclerosis [10][11][12][13].…”

Edible Oxya chinensis sinuosa—Derived Protein as a Potential Nutraceutical for Anticancer Immunity Improvement

et al. 2020

Oxya chinensis sinuosa (Ocs) is consumed as representative edible insects in Asia, but its function in various immune systems remains unclear. This study aimed to demonstrate the immunomodulatory effect, particularly on the innate and adaptive immune response, of Ocs protein (Ocs-P) and to investigate its function as a potent anticancer immunostimulant when administered during the progression stage of colon carcinoma in tumor-bearing mice. Our in vitro results demonstrated that Ocs-P treatment induces phenotypic alteration (increased expression of surface molecules and production of Th1-polarizing cytokines and decreased antigen uptake ability) of dendritic cells (DCs) through the activation of MAPK and NF-κB-dependent signaling pathways. Additionally, Ocs-P-stimulated DCs initiated differentiation of naive T cells into IFN-γ-producing Th1-type T cells effectively and activated cytotoxic CD8+ T cell response. In colon carcinoma-bearing mouse models, oral administration of Ocs-P inhibited tumor growth and restored the expression of decreased surface molecules in lineage-CD11c+MHC-II+ splenic DCs. Furthermore, Ocs-P administration enhanced the generation of multifunctional CD4+ and CD8+ T cells expressing Th1-type cytokines (TNF-α, IFN-γ, and IL-2) and the degranulation marker (CD107a). Collectively, these results suggest that Ocs-P demonstrates an immunostimulatory effect and may induce powerful anticancer immunity.
