Hermetia Illucens Larvae

One third of food produced globally is wasted. Disposal of this waste is costly and is an example of poor resource management in the face of elevated environmental concerns and increasing food demand. Providing this waste as feedstock for black soldier fly (Hermetia illucens) larvae (BSFL) has the potential for bio-conversion and valorisation by production of useful feed materials and fertilisers. We raised BSFL under optimal conditions (28 °C and 70% relative humidity) on seven UK pre-consumer food waste-stream materials: fish trimmings, sugar-beet pulp, bakery waste, fruit and vegetable waste, cheese waste, fish feed waste and brewer’s grains and yeast. The nutritional quality of the resulting BSFL meals and frass fertiliser were then analysed. In all cases, the volume of waste was reduced (37–79%) and meals containing high quality protein and lipid sources (44.1 ± 4.57% and 35.4 ± 4.12%, respectively) and frass with an NPK of 4.9-2.6-1.7 were produced. This shows the potential value of BSFL as a bio-convertor for the effective management of food waste.

ABSTRACT. Maggot Hermetia illucens (Maggot Black Soldier Fly, MBSF) is an alternative protein source besides soybean meal (SBM) which may be used as a feed for improving the quality of semen particularly in Garut rams to support prolific nature. The aims of this study were to analyzed and compare the impact of different protein sources in feed on semen quality of Garut rams, and to assess the prediction ability of Garut rams to serve ewe in small-scale breeders in West Java, Indonesia. This study was conducted using a completely randomized design with 3 treatments and 4 replications, consisted of Brachiaria humidicola (BH) grass and T1 (concentrate contains 20% of SBM), T2 (concentrate contains 10% of SBM and 10% of MBSF), and T3 (concentrate contains 20% of MBSF). The parameters measured were feed consumption, semen quality (macroscopic and microscopic characteristics), also a potential ability of rams to serve ewe. The results showed there were no significant effect on protein consumption, semen volume, semen pH, semen color and consistency, sperm mass movement, sperm motility, sperm concentration, sperm morphology, and prediction potential ability to serve ewe. However, the result showed a significant effect (P0.05) on sperm viability and sperm plasma membrane integrity. Sperm plasma membrane integrity of ram feed with T3 was better than T1 and T2 (P0.05). The prediction potential ability rams to serve ewes on MBSF treatment was 38 heads, while in T1 and T2 were 43 and 57 heads, respectively. In conclusion, MBSF can be an alternative source of protein besides SBM to improve the semen quality of Garut rams.  ABSTRAK.

Treatment Procedures

The black soldier fly (BSF, Hermetia illucens) is considered a potential sustainable insect alternative source of protein for animal feed. The quality of a BSF meal is greatly influenced by the killing method and the purpose of this article is to compare the influences of different killing methods. BSFs at the 18-day-old prepupae stage were separated into six different killing methods with three replicates: 1. blending, 2. freezing, 3. CO2 treatment, 4. vacuum, 5. blanching and 6. CO2 plus blanching. After killing, BSF larvae meals were obtained by hot air oven drying and grinding. The chemical composition and in vitro digestibility calculated from sediments were not affected by the killing method, except that blending provided the worst BSF quality for all measured parameters (p < 0.05). The highest quality of BSF was obtained from the heat treatment procedures (blanching and the CO2 plus blanching methods), as they produced lower acidity after killing, total viable counts, browning reaction (enzymatic and non-enzymatic), darkness, moisture, fat acidity, protein and lipid oxidation during storage compared with other killing procedures (p < 0.05). Interestingly, the highest free amino acids in the supernatant after in vitro digestibility of BSF samples was observed with the CO2 plus blanching killing method (p < 0.05), whereas other parameters were similar to those obtained with blanching. The CO2 plus blanching method did not produce clearly different outcomes to blanching; therefore, the selection of one of these techniques over the other should depend on the regulations in each country.

Protein Diets

The larvae and prepupae of the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae) have been explored as a means for alternate protein production for feed for animals that are raised for human food. However, processes for production of these and other insects must be refined if cultivation is to become widespread and efficient. In this study, black soldier fly larvae were fed one of six diets, consisting of the Gainesville house fly diet (control), and five diets of varying ratios of sorghum and cowpea. Effects on life-history traits and nutritional content of prepupae were observed. Flies were able to successfully complete larval development on all diets tested. There were significant differences in development rates based on diet, particularly the diets containing a higher percentage of sorghum. In general, larvae reared on the sorghum diets (which were lower in protein than that of the cowpea diets), developed slower (3-9 days longer from larval eclosion to the prepupal stage) than those on the cowpea diets. Diet treatment did not consistently influence weight or length of prepupae. Higher protein diets (7.73% protein) translated to higher protein content of prepupae (43.70-47.29% protein) and lower protein diets (3.51% protein) resulted in greater gross energy content of prepupae (5.22-6.21 Kcal/g). These differences suggest that macro-nutrient content of prepupae can be influenced by larval diet. This study provides further evidence of the viability of black soldier flies for protein production.

Hermetia Illucens Larvae

The production of black soldier fly (Hermetia illucens) larvae (BSFL) is rapidly becoming a new method to convert food waste into a sustainable ingredient in terrestrial and aquatic nutrition while the by-product, called ‘frass’, can be used as a soil amendment. The growth and nutritional quality of BSFL and their frass is greatly influenced by the provided substrates. In this study, fruits, vegetables, starches and in their combination (mixture) were provided to BSFL for two weeks and afterwards their final weight and nutritional composition of the BSFL and frass were measured. The starch treatment produced significantly heavier BSFL compared to those in the fruit treatment. However, BSFL produced from starch had the lowest amino acid levels. The BSFL produced from vegetables had significantly higher crude protein and essential amino acids compared to all substrates, with the exception of histidine. Frass produced from vegetables had significantly higher nitrogen-phosphorus-potassium values compared to all others, with the exception of nitrogen in the starch and mixture treatment. This study showed that the use of vegetables produced BSFL and frass comparable to soybean meal and many organic fertilisers, respectively, and these could be valuable and sustainable resources for the agricultural industry.

Guaranteed Service

Canteens represent an essential food supply hub for educational institutions, companies, and business parks. Many people in these locations rely on a guaranteed service with consistent quality. It is an ongoing challenge to satisfy the demand for sufficient serving numbers, portion sizes, and menu variations to cover food intolerances and different palates of customers. However, overestimating this demand or fluctuating quality of dishes leads to an inevitable loss of unconsumed food due to leftovers. In this study, the food waste fraction of canteen leftovers was identified as an optimal diet for black soldier fly (Hermetia illucens) larvae based on 50% higher consumption and 15% higher waste reduction indices compared with control chicken feed diet. Although the digestibility of food waste was nearly twice as high, the conversion efficiency of ingested and digested chicken feed remains unparalleled (17.9 ± 0.6 and 37.5 ± 0.9 in CFD and 7.9 ± 0.9 and 9.6 ± 1.0 in FWD, respectively). The oil separator waste fraction, however, inhibited biomass gain by at least 85% and ultimately led to a larval mortality of up to 96%. In addition to monitoring larval development, we characterized physicochemical properties of pre- and post-process food waste substrates. High-throughput amplicon sequencing identified Firmicutes, Proteobacteria, and Bacteroidota as the most abundant phyla, and Morganella, Acinetobacter, and certain Lactobacillales species were identified as indicator species. By using metagenome imputation, we additionally gained insights into the functional spectrum of gut microbial communities. We anticipate that the results will contribute to the development of decentralized waste-management sites that make use of larvae to process food waste as it has become common practice for biogas plants.
