Chitin and chitosan are biopolymers that frequently found in nature have a broad range of applications the food, biomedical industrial sectors, due to their high biological activity. The primary source chitin is shellfish, however, shortages supply chain, seasonality issues availability, as well ecological degradation only few problems with main resources. Due spectrum for which can be used, demand its derivatives increasing. Therefore, market looking widely available, greener alternatives commercial sources. Insects appear suitable candidate fill this gap. During insect rearing processing, number side streams generated, e.g., exuviae larvae pupae, dead adults, etc. currently mostly discarded waste. However, these could constitute novel long-term applications. Recent research has demonstrated suitability several edible species production chitosan, wherein exoskeleton black soldier fly field cricket rich chitin, making them good extraction purification among other farmed candidates. Moreover, potential uses been identified insect-derived chitosan. Thus, review aims present recent advances from insects, specifically on purification, agriculture, food nutrition, biomedicine bioplastic production.

Abstract Chitosan is one of the most abundant biopolymers in nature with high economic value due to its biocompatibility, biodegradability, lack toxicity, and antifungal activity. In this study, chitosan was extracted from three different sources: Blaps lethifera (CSB), Pimelia fernandezlopezi (CSP), Musca domestica (CSM). The ash content (AC), moisture (MC), fat binding capacity (FBC), water (WBC), deacetylation degree (DD) were determined for prepared chitosans. effect DD on antibacterial activity gram (positive/negative) bacteria azo dyes (methylene blue, MB) removal wastewater also investigated. extracts showed good against Listeria innocua , Bacillus subtiliis Staphylococcus aureus Salmonella typhimurium Pseudomonas aeruginosa . MB dye CSB-chitosan, CSP-chitosan, CSM-chitosan reached 37%, 87%, 26%, respectively, at a contact time 2 h, low initial concentration 13 ppm, solution temperature 25 °C, pH = 7. Graphical
