Chitin was extracted from the cuttlebone of Sepia kobiensis and chitosan was prepared through deacetylation. The chitosan was characterized for its structural, physical and thermal (CHN, DDA, FT-IR, NMR, XRD, Viscometric analysis, SEM and DSC) properties. Further, the chitosan exhibited the antioxidant activity of 50.68-74.36% at 1-10 mg ml(-1) and it also showed the reducing power of 0.28% at 1 mg ml(-1). At 10 mg ml(-1), the chitosan exhibited the scavenging ability of 46.17%, on 1,1-diphenyl-2-picrylhydrazyl radicals, 23.38-73.70% on superoxide radicals at 0.05-1.6 mg ml(-1) and 18.34% to 62.39% (0.1-3.2 mg ml(-1)) on hydroxyl radicals; whereas at 1-10 mg ml(-1) the chelating ability on ferrous ions was calculated as 49.74-73.59%. Based on the potential antioxidant activity, scavenging ability on hydroxyl radicals and chelating abilities on ferrous ions, the chitosan from the cuttlebone of S. kobiensis may not only be used as a potent natural antioxidant but also as a possible food quality enhancer ingredient in the pharmaceutical industry.

Background This study investigated the anticoagulant properties of sulfated chitosan derived from the internal bone of the spineless cuttlefish . Chitosan, a biopolymer, is used in various biomedical applications including anticoagulation. Sulfation of chitosan enhances its biological activity, making it a potential therapeutic agent.

Background This study aimed to isolate linear polysaccharides from cuttlebone with the objective of evaluating their ability to scavenge free radicals. By providing new natural components for pharmaceutical and functional food uses, this research advances our understanding of the potential health benefits of polysaccharides originating from marine sources and their antioxidant properties. Objective The objective of the study is to isolate a linear polysaccharide chitosan from cuttlebone (produced by the partial deacetylation of chitin), characterize its structure using fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD), and explore the isolated polysaccharide's free radical scavenging potential.

Cuttlefish bone biowaste is a potential source of a composite matrix based on chitin and aragonite. In the present work, we propose for the first time the elaboration of biocomposites based on chitosan and aragonite through the valorization of bone waste. The composition of the ventral and dorsal surfaces of bone is well studied by ICP-OES.

In fish processing, reducing the waste rate and increasing the economic value of products is an important issue for global environmental protection and resource sustainability. It has been discovered that cuttlefish bones can be an excellent resource for producing attractive amounts of chitin and chitosan. Therefore, this study optimized chitosan extraction conditions using response surface methodology (RSM) to establish application conditions suitable for industrial production and reducing environmental impact.
