Current estimations showed that the number of people affected by hunger doubled in last two years, reaching 9.8% global population. According to FAO, order satisfy demand for food next few it will be necessary double production. Moreover, call a change dietary patterns has been raised, showing how sector is responsible 1/3 climate where meat-based diets or overconsumption meat play an important role negative environmental impact. Consequently, there growing concern achieve goal increasing productions without exploiting resources and explore production use alternative resources, such as insects. Insects are gaining interests both feed not only reduce costs common livestock, but also farmers' dependence on traditional protein sources. In this work we aimed provide overview state-of-the-art upon insect studies, highlighting most results obtained from industrial market perspective. The legislative framework concerning edible insects analyzed, with final purpose highlight recent reforms, relevant case-law well unsolved regulatory challenges.

Assessing the Socio-Economic Benefits and Costs of Insect Meal as a Fishmeal Substitute in Livestock and Aquaculture

Animals, Journal Year: 2024, Volume and Issue: 14(10), P. 1461 - 1461

Published: May 14, 2024

Sustainability targets set by the United Nations, such as Zero Hunger 2030, encourage search for innovative solutions to enhance food production while preserving environment. Alternative protein sources feed, conventional resources like soymeal and fishmeal become more expensive scarcer, is one of possibilities. Studies on substituting with insect meal show promising results in terms animal growth feed efficiency. This paper aims assess socio-economic benefits costs highlight factors influencing performance most. The study evaluates economic value insect-based products, waste reduction, reduced greenhouse gas emissions benefits. It combines empirical data derived from laboratory trials two case studies covering black soldier fly (Hermetia illucens) yellow mealworm (Tenebrio molitor). Current analyses reveal negative balances, emphasizing that reduction operating investment through upscaling technological advancements can give a positive move, well current market valuations nutrients change significantly. Thus, balance at moment does not mean rearing, larva processing are desirable long-term perspective.

Closing Nutrient Cycles through the Use of System-Internal Resource Streams: Implications for Circular Multitrophic Food Production Systems and Aquaponic Feed Development

Sustainability, Journal Year: 2023, Volume and Issue: 15(9), P. 7374 - 7374

Published: April 28, 2023

In order to further close nutrient cycles of aquaponic systems, it could be possible integrate a third trophic level in the form insect larvae production (i.e., black soldier fly larvae) recycle internal waste streams into valuable nutrients. This would present opportunities formulate sustainable circular aquafeeds that combine these internally available nutrients with complementary external raw materials. The ingredient composition feeds for such multitrophic food systems (CMFS) may affect fish performance as well excretion important dissolved plant N, P and K. Hence, meal from catfish processing (CM) base was combined variable levels poultry by-product (PM) (BSFM) three marine-ingredient-free experimental diets corresponding hypothetical scenarios CMFS aims aquaponics production. These commercial diet (COM) were compared using isonitrogenous isolipidic formulations. They fed African (Clarias gariepinus) recirculating aquaculture (RAS) evaluated concerning growth excretion. All resulted similar total inorganic nitrogen (TIN) excretion, whereas increase dietary PM inclusion 0% (BSF diet) 20% (MIX 41% (PM concomitant reduction BSFM led increasingly higher soluble reactive phosphorus (SRP) per unit feed COM diet. While enabled best conversion performance, MIX especially BSF produced more diet, which generated highest K Ca P, yet lower N content feces.

Effect of fatty acid-enriched black soldier fly larvae meal combined with chitinase on the metabolic processes of Nile tilapia

British Journal Of Nutrition, Journal Year: 2024, Volume and Issue: 131(8), P. 1326 - 1341

Published: Jan. 2, 2024

Abstract The aim of this study is to determine what extent the addition chitinase black soldier fly (BSF) larval meal enriched or not with long-chain PUFA (LC-PUFA) could improve growth, protein digestion processes and gut microbial composition in Nile tilapia. Two different types BSF were produced, which larvae reared on substrates formulated vegetable culture substrate (VGS) marine fish offal (FOS). raised VGS was α -linolenic acid (ALA), while that FOS ALA + EPA DHA. Six BSF-based diets, chitinase, compared a control diet based fishmeal oil (FMFO). doses (D) from Aspergillus niger (2 g 5 g/kg feed) added diets (VGD0 FOD0) obtain four additional diets: VGD2, VGD5, FOD2 FOD5. After 53 d feeding, results showed BSF/FOS-based induced feed utilisation, efficiency digestibility, as well growth comparable FMFO diet, but better than BSF/VGS-based diets. supplementation BSF/FOS increased intestine relative abundance beneficial microbiota such those Bacillaceae family. LC-PUFA-enriched associated be used an effective alternative order processes, ultimately rate.

Review: Insects as a novel feed ingredient: processing technologies, quality and safety considerations

animal, Journal Year: 2025, Volume and Issue: unknown, P. 101495 - 101495

Published: March 1, 2025

The current food system is placing significant strain on limited available resources. Novel protein sources have been suggested as a potential solution for ensuring further growth without compromising the natural balance of planet. In this direction, edible insects appear to be crucial players. Consumers may not always prefer direct use human food, indicating that indirect animal feed might more suitable. Insects are characterised by high nutritional value and similar digestibility compared traditional such soybean meal fishmeal. However, effective introduction in diets requires one or processing operations. Processing paramount microbiological safety while improving quality, palatability insect. Additionally, could allow combination insect-based ingredients with other ingredients, obtaining uniform stable mixture, which can easily conveniently provided farmed animals. review, an overview most common methods (blanching, grinding, drying, mixing, extrusion) applied aim delivering high-quality presented. Each step carefully evaluated, pros cons each operation considered important recommendations provided. Barriers opportunities advancing within sector finally illustrated. A strong emphasis placed need evaluating effect any quality insect-derived products, particularly considering possibility replacing materials.
