S2 Journal of Insects as Food and Feed 4 Supplement 1 Keynotes 1 Insects for food, feed and health: a global perspective A. van Huis Wageningen University & Research, Laboratory of Entomology, Droevendaalsesteeg 1, 6708 PB Wageningen, the Netherlands; [email protected] During the last ten years there has been a growing interest worldwide to use insects as food, feed or pharma. This is exemplified by the increasing number of start-ups, the emergence of some large international companies, the willingness to invest in this sector, the legislation becoming gradually more conducive and the growing public and academic interest. This is because, it is realized that the growing demand for animal-based protein cannot be satisfied by the amount of agricultural land available. Besides livestock production has a negative impact on the environment, while there are concerns around human health. Insects both as food and feed pose a viable and sustainable alternative, while contributing to a circular economy by transforming low value organic side streams into high value protein products. However, it requires the development of new value chains, and attention to issues such as production costs, food safety, scalability and consumer acceptance. The feed industry in particular requires reliable large supplies of high and standard quality. At the production unit major challenges are: to obtain and maintain a genetic stock; to prevent and control pests and diseases; to choose an appropriate facility design and technology to control temperature, humidity and light; using left- over substrates as fertilizer; and addressing insect welfare. The organic side-stream chosen as feed is of crucial importance as it influences costs, larval development, and the nutritional and food safety quality of the end product. Most edible insect species appear to be good sources of amino acids, fatty acids, and micronutrients. However, there are compounds such as chitin and anti-microbial peptides that may have additional health benefits compared to conventional food and feed sources. Processing can be a simple drying and grinding of the insects or more elaborate biorefinery processes to isolate chitin, protein and fat. Consumers may be persuaded by concentrating on tastiness, product design, marketing and promotion. The legal environment to produce and market insect products is often not conducive and needs major attention. The sector faces huge challenges and needs pro-active support by regional, and (inter)national authorities in terms of legislation, research and training. Large companies are often very secretive about their operations but what about farmers who want to shift from livestock to mini-livestock? The increasing number of stakeholder conferences, symposia and workshops organized at the national and international level shows that a new sector is emerging. It can only be successful if the challenges are met when private, public and academic institutions join forces. Keynotes 2 The resource of edible insects in China Y. Feng, X. Chen and M. Zhao Research Institute of Resource Insects, CAF, Bailongsi, Panlong District, Kunming, Yunnan, 650233, China P.R.; [email protected] Edible insects have attracted extensive attention worldwide over the recent years since they have the potential to resolve the global food shortage and insufficiency of animal proteins. Many countries have a history of using insects as food. It is believed that insects have been used as a food source in China for more than two thousand years. According to incomplete statistics, there are more than 300 insect species which could be used as food or as food ingredient. Most insects are in the orders of Lepidoptera, Coleoptera and Hymenoptera, contributing to 71% of total numbers. Others are insect species in the orders of Orthoptera, Hemiptera, Isoptera, and Odonata. Bees, wasps, silkworms, crickets, bamboo caterpillars, dragonflies and beetles are the most popular kinds of edible insects in many regions of China. However, most of the consumed edible insects are collected from the wild. People consider food coming from the wild as natural and healthy food. Another reason is the lack of appropriate technologies to farm edible insects. Therefore, edible insects are not a main source of food at present. Several factors have influenced the utilization of insects as food, such as consumer acceptance, food security and lack of large-scale farming technologies. We consider that the development of large-scale farming and process technology are the most important conditions for the advancement of an edible insect sector in China. However, several efforts have been made. Some wasp and locust species are farmed using semi-domestication methods. This is also true for mealworm and cockroach species. Currently the scale of rearing is too small to meet human food requirements at a large scale. Many efforts are still needed to reach a level of industrialization of edible insect farming. Journal of Insects as Food and Feed 4 Supplement 1 S3 Keynotes 3 Research and industrialization of Hermetia illucens L. in China J.B. Zhang, L.Y. Zheng, M.M. Cai and Z.N. Yu Huazhong Agricultural University, State Key Laboratory of Agricultural Microbiology, College of Life Science and Technology, Wuhan, 430070, China P.R.; [email protected] Hermetia illucens L. (Diptera: Stratiomyidae), also known as black soldier fly (BSF), can be found in decaying organic wastes, such as animal manure and food waste. Over the past 14 years, investigators in China have conducted a tremendous amount of research on the BSF. In the beginning we imported the technique from Dr Jeffery Tomberlin, Texas A &M University, USA. Then, China collected wild species of H. illucens in Wuhan and Guangdong Province and domesticated them. Research found that the quartz-iodine lamp can replace natural light inducing BSF adults to mate and lay eggs in cloudy days. We also isolated microbes that could induce BSF to lay eggs, resulting in increased production. These innovations allow the mass production of black soldier fly larvae (BSFL) at a large scale throughout the year. BSF gut microbes play important roles in BSFL nutrition and resistance against pathogens. Bacteria isolated from the BSFL gut and eggs can be cultured and used to promote BSF growth, and shorten the time from hatching to the prepupal stage. BSF not only convert kitchen waste and livestock manure, but also could convert mushroom residues, soybean residues, silkworm faeces and algae waste. We found BSFL could also degrade antibiotics in livestock manure as well as remove odours in livestock manure. These processes greatly reduce environmental impact caused by organic waste. BSFL fat also could serve as a novel low cost biomass feedstock for biofuel. Industrialization of BSF for recycling kitchen and animal waste is well established in China. The treatment process have several models: manual, mechanization and automation model. Some companies in Wuhan city, Xian city, Tianjin city, Hainan Province, Hunan Province and Guangdong Province recycle kitchen waste and livestock manure at a large scale.
