“…Viscosity of this chitosan was 62.4 cP with a molecular weight of 308.3 kDa. Molecular weight of chitosan in the exoskeleton of a cockroach (Periplaneta americana L.) ranges from 210 to 230 kDa (Kim et al 2017b). The molecular weight of chitosan from grasshopper is 7.2 kDa in adult and 5.6 kDa in nymph (Erdogen & Kaya 2016).…”

The purpose of this study was to investigate the production of chitin and chitosan from both the exuvium and whole body of mealworm (Tenebrio molitor) larvae. Chitin from the exuvium and whole body of T. molitor larvae was chemically extracted with acid and alkali solutions to achieve demineralization (DM) and deproteinization (DP), respectively. The average DM (%) and DP (%) on a dry weight (DW) basis was 32.56 and 73.16% from larval exuvium, and 41.68 and 91.53% from whole body, respectively. To obtain chitosan, chitin particles from the exuvium and whole body of T. molitor larva were heated at various temperatures in different concentrations of NaOH. Average chitin yields were 18.01% and 4.92% of DW from the exuvium and whole body, respectively. The relative average yield of chitosan from whole body was 3.65% of DW. On average, over 90% of chitosan derived from whole body was deacetylated. The viscosity of chitosan from whole body was ranged from 48.0 cP to 54.0 cP. The chitin content of dry and wet byproducts from whole body were 17.32% and 16.94% respectively, compared to dry weight. The chitosan contents of byproducts on a DW basis were 14.48% in dry and 13.07% in wet byproduct. These results indicate that the exuvium and whole body of T. molitor larva may serve as a source of chitin and chitosan for use in domestic animal feed.

Edible insects are not only good food ingredients for people, but also open the possibility of functional food and pharmaceutical raw materials. This study investigated the production of chitin‐oligosaccharide and chitosan‐oligosaccharide using edible insect, Tenebrio molitor (Tm). Chitin of Tm larvae was prepared using demineralization (2 N HCl, room temp., 3 h), deproteinization [5% NaOH (w/w) for 3.5 h at 70°C], and decolorization (3% H2O2 for 1.5 h at 80°C). Chitosan of Tm larvae was prepared by Tm chitin deacetylation at 50% NaOH (w/w) for 5 h at 105°C. The chitin of Tm yielded 50% chitosan, and the final extraction yield of chitin and chitosan from dried Tm larvae was 6.82% and 3.75%, respectively. Chitin‐oligosaccharide and chitosan‐oligosaccharide of Tm larvae were prepared via acid hydrolysis using 5.0 g of both Tm chitin and Tm chitosan. Finally, 2.12 g chitin‐oligosaccharide of Tm larvae was obtained through acid hydrolysis (con. HCl 100 mL for 4 h at 40°C). Chitosan‐oligosaccharide (2.5 g) of Tm larvae was produced via acid hydrolysis (con. HCl 50 mL for 1 h at 81°C) and purification. These results indicate that the industrial applicability of Tm chitin‐oligosaccharide and chitosan‐oligosaccharide is viable in the field of health supplements, as a large amount of these oligosaccharides can be obtained from edible insect, Tm larvae.

The marine food‐processing industries were producing large quantities of shell wastes as a discard. Currently, this waste material was underutilized and leads to the landfill as a significant environmental issue. The outer shells or exoskeletons of mollusks serve as the best source of chitin. Three different allomorphs of chitin (γ, β, and γ) were extracted from different species of crustaceans, mollusks, and fungi. β‐Allomorphs predominantly exist in the shells of mollusks. β‐Chitin and its deacetylated product chitosan has been utilized for its special characteristic features, including biocompatibility, environmental friendly, and nontoxic properties. The extraction of β‐chitin and chitosan from the mollusk shell waste were evaluated in this work. Hence, this review aims to explore edible mollusk shell waste sources and its suitable extraction techniques, characterizations, and functional properties of mollusk‐based β‐chitin and chitosan. Further, the genetic pathway of synthesizing mollusk chitin was discussed. The entire life cycle assessment with techno‐economic aspects were extrapolated to study the bottlenecks and tangible solution for the industrial upscaling of obtaining β‐chitin and chitosan from the edible mollusk shell waste have been reviewed herein.
