Abstract Yellow mealworm larvae (YML; Tenebrio molitor ) are considered as a valuable insect species for animal feed due to their high nutritional values and ability grow under different substrates rearing conditions. Advances in the understanding of entomophagy nutrition over past decades have propelled research areas toward testing multiple aspects YML exploit them better sources. This review aims summarize various approaches that could be exploited maximize an ingredient. In addition, has potential used antimicrobial or bioactive agent improve health immune function production animals. The dynamics profile can influenced by factors should taken into account when attempting optimize nutrient contents Specifically, use novel land-based aquatic feeding resources, probiotics, exploitation larval gut microbiomes strategies assist YML. Selection relevant supplies, optimization ambient conditions, introduction genetic selection procedures, implementation effective post-harvest processing may required future commercialize production. Furthermore, appropriate agricultural practices technological improvements within sector aimed at achieving both economic environmental sustainability. issues highlighted this pave way value

Nutritional Composition and Safety Parameters of Mealworms (Tenebrio molitor) Reared on Substrates Derived from By-Products

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(7), P. 2744 - 2744

Published: March 25, 2024

Mealworms provide a viable option for transforming agricultural and food processing by-products that can be converted into valuable source of high-quality protein fat suitable both animals humans. Hence, our investigation was aimed at employing sprouted green potatoes, wheat bran, from brewers’ production as comprehensive substrate rearing mealworms. The nutritional value (fat content) composition amino acids (AAs) fatty (FAs) were tested in lyophilized milled larvae. results showed the highest amount detected sample 3L (59.18 ± 007%), grown on spent grain, whereas 2S (with bran) comes out with content (34.22 0.491%). It found FAs larvae depended used: statistically monounsaturated potatoes (1L), omega-3 control (4CL), agar–agar gels, brewers grains (3L) higher oleic acid. Meanwhile, total polyunsaturated (36.23%) bran (2L). During study, 16 distinct AAs have been analyzed, has demonstrated 11 instances. is noteworthy containing grain exhibited peroxide levels, indicating oxidation. determined number volatile did not exceed regulatory limits meat. In summary, it asserted adjusting essential extracting specific FAs. However, this could potentially affect peroxides. This adaptation enables desired chemical larvae, making purposes such animal or human nutrition health enhancement.

Bioconversion of organic waste by insects – A comprehensive review

Process Safety and Environmental Protection, Journal Year: 2024, Volume and Issue: 187, P. 1 - 25

Published: April 28, 2024

The ever-growing human population has forced people to intensify agriculture meet the demand for food and feed. However, increase in global agricultural production also means an waste generation, which is mostly improperly managed, especially low- middle-income countries where adequate management infrastructure limited inefficient. Consequently, organic become a burden due its negative impact on environment health. In this sense, insect-based bioconversion could be economically viable, environmentally friendly, technically feasible approach management. Based review, wastes from agriculture, industry, household, municipalities, starch industry are considered as suitable substrates bioconverter insects. Commonly used insects include cricket, yellow mealworm, superworm, black soldier fly, house flesh fly blow fly. Rearing facilities must adapted provide optimal environmental conditions growth development of reared insect maximize rate efficiency. Bioconverter their by-products can industrially processed into animal feed, fertilizer biodiesel or extracted isolate bioactive compounds. challenges associated with social acceptance, method-, infrastructure- technology-related problems, availability substrates, political legal regulations. summary, potential reduce waste, create jobs, novel products, offer sustainable source protein feed world's growing population.

Alternative and Sustainable Protein Sources in Pig Diet: A Review

Animals, Journal Year: 2024, Volume and Issue: 14(2), P. 310 - 310

The search for alternative protein sources to soybean meal (SBM) in animal feeding is a strategic objective reduce production costs and contribute sustainable production. Spirulina, due the high content, has emerged as potential cost-effective, sustainable, viable, high-nutritional-value food resource many species. Insect larvae (Tenebrio molitor Hermetia illucens) are also considered alternatives SBM, given their edible percentage of almost 100%, well value higher than that vegetable proteins. Rapeseed grain legumes, such fava beans, peas, lupins, chickpea, can be used locally producible ingredients. This study reviews nutritional these SBM pig diets, effects on performance, digestion, immune system, physicochemical sensorial characteristics meat, including processed pork products. limits use reviewed indicate gaps filled future research supplementation level diets.

Nutritional Value and Microbiological Aspects of Dried Yellow Mealworm (Tenebrio molitor L.) Larvae Pretreated with a Pulsed Electric Field

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(3), P. 968 - 968

Published: Jan. 23, 2024

Complete protein, which includes all the essential amino acids, and bioactive compounds needed in human nutrition, can be found edible insects. Bioactive play a crucial role protecting cells from damage caused by free radicals. Therefore, this study, fat extraction yield, protein content, acid profile, total polyphenol antioxidant properties, crustacean mollusk microbiological quality have been assessed to evaluate influence of drying method pulsed electric field (PEF) pretreatment. To end, sample was processed PEF at varied specific energy intakes (5, 20, 40 kJ/kg) dried means two methods: convective (CD) infrared-convective (IR-CD). A comparable content (47.5–48.7 g/100 g d.m.) determined for most samples tested. significantly higher lysine methionine detected CD insects, especially treated kJ/kg. The IR-CD exhibited polyphenols as compared those obtained method, whereas apparently had significant impact extent increasing their content. Taking into account allergenicity, approximately 10 times than study has shown that treatment prior resulted assurance insects food use. Furthermore, dose 20 kJ/kg demonstrated antimicrobial effect. results proven that, case, high temperature during did not cause undesirable changes expected. PEF-assisted may conceivably considered obtain highly nutritionally valuable insects; however, it is utilize appropriate parameters course processing.
