“…The chitin and chitosan content of Odonata including Sympetrum fonscolombii and Anax imperator ranges between 20.3 and 67% DW ( Kaya et al, 2014 ; Kaya et al, 2016 ). Besides, the chitin and chitosan content in cockroach, Periplaneta americana varied between 3.36 and 26.9% and 0.024–2.08%, respectively ( Kaya, Baran, & Karaarslan, 2015 ; Kaya et al, 2017 ; M.-w.; Kim, Song, Han, et al, 2017 ; Wanule, Balkhande, Ratnakar, Kulkarni, & Bhowate, 2014 ). In comparison with this amount, Ranatra linearis had 15–16% of chitin, 6.70% in Cicadatra atra , 5.51% in C. hyalina , 36.6% in Cicada slough, 4.97% in Cicada lodosi , 6.49% in C. mordoganensis , 8.84% in Cicadatra platyptera , 5.88% in C. tibialis and 62.42% in Cryptotympana atrata ( Mol, Kaya, Mujtaba, & Akyuz, 2018 ; Sajomsang & Gonil, 2010 ; S.-J.…”

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.

“…High temperatures are used for very short periods (20-30 min), as reported by Kaya et al 100 and Monter-Miranda et al 119 In contrast, longer treatment periods (12-24 h) are applied for incubations done at room temperature. 106,114,123 High temperatures promote the penetration of the solvent into the chitin matrix 145 ; however, they can cause polymer degradation. 25 The efficiency of demineralization (DME) can be evaluated by assessing the mineral content of insect samples before (MC BT ) and after treatment (MC AT ) according to the following equation:…”

“…The same is true for chitin and chitosan derived from crustaceans, where the wavenumbers of the peaks can vary slightly among different natural sources. 88 For insect-based chitin and chitosan, infrared spectra were used to confirm the homogeneity of chitin and chitosan isolated from several insect species, 113 to compare the spectral bands with those of commercially available chitin and chitosan 94,123 or to confirm the purity of insect-based chitin after the isolation process 106 by considering the strength and position of characteristic bands.…”

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.
