“…Deproteinization efficiency of insect biomass has been mentioned only by Kim et al 110,111 In both cases a maximum efficiency of 86-87% was achieved by applying 1.25 mol L −1 sodium hydroxide for 3 h at 95°C on adult specimens of M. domestica 110 and G. bimaculatus. 111 These values are similar to those obtained by Zhou et al, 133 who used natural deep eutectic solvents to remove proteins from H. illucens prepupae. The deproteinization efficiency of sodium hydroxide on crustacean shells at both high and room temperature was 71-76%.…”

“…Using various times and temperatures for both demineralization and deproteinization treatments, they obtained similar results, that is, between 93 and 97%. Using natural deep eutectic solvents, Zhou et al 133 achieved a slightly lower degree of purification (74-91%) from H. illucens prepupae. The lack of quantitative assessment of the purity of insect-based chitin makes it difficult to evaluate the suitability of the methods.…”

Chitin, and especially its deacetylated variant chitosan, has many applications, e.g. as carrier material for pharmaceutical drugs or as a flocculant in wastewater treatment. Despite its versatility and accessibility, chitin, the second most abundant polysaccharide on Earth, has so far been commercially extracted only from crustaceans and to a minor extent from fungi. Insects are a viable alternative source of chitin, but they have not been exploited in the past due to limited availability. Today however, for the sustainable production of animal feed, insect farming is being developed substantially. The availability of large quantities of insect biomass and chitin-rich side products such as exuviae and exoskeletons has been increasing. This review provides an overview of recently published studies of chitin extraction from insects, its subsequent conversion into chitosan and the primary analytical methods used to characterize insect-based chitin and chitosan. We have discovered a large number of research articles published over the past 20 years, confirming the increased attention being received by chitin and chitosan production from insects. Despite numerous publications, we identified several knowledge gaps, such as a lack of data concerning chitin purification degree and chitosan yield. Furthermore, analytical methods used to obtain physicochemical characteristics, structural information and chemical composition meet basic qualitative requirements but do not satisfy the need for a more quantitative evaluation. Despite the current shortcomings that need to be overcome, this review presents encouraging data on the use of insects as an alternative source of chitin and chitosan in the future.

“… Zhang, Vigier, Royer, & Jerome, 2012 ). DES extraction has been used for chitin production from shrimp ( Huang, Zhao, Guo, Xue, & Mao, 2018 ) and lobster ( Hong, Yuan, Yang, Zhu, & Lian, 2018 ; Zhu, Gu, Hong, & Lian, 2017 ), as well as in the insect Hermetia illucens ( Zhou et al, 2019 ). Recently, Brigode et al (2020) reported the production of chitin from H. illucens using acid detergent fibre and acid detergent lignin methods (ADF-ADL).…”

Background Insects are a living resource used for human nutrition, medicine, and industry. Several potential sources of proteins, peptides, and biopolymers, such as silk, chitin, and chitosan are utilized in industry and for biotechnology applications. Chitosan is an amino-polysaccharide derivative of chitin that consists of linear amino polysaccharides with d -glucosamine and N-acetyl- d -glucosamine units. Currently, the chief commercial sources of chitin and chitosan are crustacean shells that accumulate as a major waste product from the marine food industry. Existing chitin resources have some natural challenges, including insufficient supplies, seasonal availability, and environmental pollution. As an alternative, insects could be utilized as unconventional but feasible sources of chitin and chitosan. Scope and approach This review focuses on the recent sources of insect chitin and chitosan, particularly from the Lepidoptera, Coleoptera, Orthoptera, Hymenoptera, Diptera, Hemiptera, Dictyoptera, and Odonata orders. In addition, the extraction methods and physicochemical characteristics are discussed. Insect chitin and chitosan have numerous biological activities and could be used for food, biomedical, and industrial applications. Key findings and conclusions Recently, the invasive and harmful effects of insect species causing severe damage in agricultural crops has led to great economic losses globally. These dangerous species serve as potential sources of chitin and are underutilized worldwide. The conclusion of the present study provides better insight into the conversion of insect waste-derived chitin into value-added products as an alternative chitin source to address food security related challenges.

Each year, the food supply chain produces more than 1.3 billion tons of food and agricultural waste, which poses serious environmental problems. The loss of the massive quantity of secondary and primary metabolites retrievable from this resource is a significant concern. What if there is a global solution that caters to the numerous problems arising due to the humongous volume of waste biomass generated in every part of the world? Insects, the tiny creatures that thrive in decaying organic matter, which can concentrate the nutrients present in dilute quantities in a variety of by-products, are an economically viable option. The bioconversion and nutritional upcycling of waste biomass with insects yield high-value products such as protein, lipids, chitin and frass. Insect-derived proteins can replace conventional protein sources in feed formulations. Notably, the ability of the black soldier fly (BSF) or Hermetia illucens to grow on diverse substrates such as agri-food industry side streams and other organic waste proves advantageous. However, the data on industrial-scale extraction, fractionation techniques and biorefinery schemes for screening the nutritional potential of BSF are scarce. This review attempts to break down every facet of insect processing and analyze the processing methods of BSF, and the functional properties of nutrients obtained thereof.
