“…Chitin is one of the most abundant amino polysaccharides found Q3 in nature next to cellulose; it has a wide variety of sources as exoskeleton of crustacean (crab, shrimp and crawfish, Oniscus asellus) [1][2][3][4], insect cuticles (Melolontha melolontha) [3], Orthoptera species [5,6], wings of cockroach [7], grasshopper species [8], medicinal fungus [9], larvae and adult Colorado potato beetle [10], aquatic invertebrates [11], bat guano [12], resting eggs of Daphnia longispina [13], spider species [14], Daphnia magna resting eggs [15], and cell wall of fungi and in the green algae. The chemical structure of chitin (C 8 H 13 O 5 N) n is similar to cellulose, having one hydroxyl group on each monomer substituted with an acetyl amine groups.…”

“…The decreasing value of the C percentage is due to the removal of acetyl groups in the chitin structure. Kaya et al [22] stated that the theoretical of N percentage for pure chitin is 6.9%. Hence, the N percentage in chitin and chitosan prepared were 9.62% and 12.00%, respectively, which are higher than 6.9% reported in literature.…”

Isolation of chitin and chitosan from natural sources are widely known as they can be used in many applications. Extraction of chitin and chitosan are carried out in exoskeleton of flower crab, Portunus pelagicus. Chemical treatments such as demineralization and deproteinzation processes are used for chitin extraction, and followed by deacetylation process of chitin, which is to produce its derivatives that known as chitosan. Characterization of chitin and chitosan has been done using Fourier Transform Infrared (FTIR) Spectroscopy, X-ray diffraction (XRD), CHNS elemental analysis and Thermogravimetric analysis (TGA). Preliminary results of FTIR vibrations patterns showed stretching of hydroxyl (O-H), amine (N-H) and carbonyl (C-O) groups indicated the presence of chitin and chitosan. XRD analysis indicates the crystalline nature of chitin and chitosan. The degree of deacetylation of chitin was characterized using CHNS elemental analyzer. The extracted chitosan will be used as reducing agent for silver nanoparticles synthesis in the future studies.Keywords: crustacean, marine invertebrates, bio-polymers, natural reductant Abstrak Pengasingan kitin dan kitosan daripada sumber semulajadi telah dikenali secara meluas kerana dapat digunakan dalam banyak aplikasi. Pengekstrakan kitin dan kitosan dari exoskeleton ketam bunga, Portunus pelagicus telah dilakukan. Rawatan kimia seperti proses demineralisasi dan proses deprotenisasi telah digunakan untuk pengekstrakan kitin dan diikuti dengan proses deasetilasi daripada ktin untuk penghasilan terbitannya yang dikenali sebagai kitosan. Pencirian kitin dan kitosan telah dilakukan dengan menggunakan Spektoskopi Inframerah Transformasi Fourier (FTIR), pembelauan Sinar X (XRD), analisis unsur CHNS dan analisis termogravimetri (TGA). Dapatan awal getaran FTIR menunjukkan regangan bagi kumpulan hidroksil (O-H), amino (N-H) dan karbonil (C-O) menunjukan kehadiran sebatian kitin dan kitosan. Analisis XRD menunjukkan sifat kristal bagi kitin dan kitosan. Pencirian darjah deasetilasi kitin telah dilakukan menggunakan penganalisis unsur CHNS. Ekstrak kitosan akan digunakan sebagai agen penurun bagi sintesis nanopartikel perak untuk kajian masa hadapan.Kata kunci: krustasea, invertebrata marin, bio-polimer, penurun semulajadi. IntroductionPolysaccharides have given many advantages in life science as their unique structure has shown some potential as natural bioactive component. Chitin is the second most abundant of polysaccharides on earth after cellulose that formed a linear chain of acetylglucosamine group. Chitin can be isolated from exoskeleton of crustacean for instance; shrimp shells [1], crab shells [2], fish scales [3], gastropod shell and operculum [4]. Chitin is available in three different forms, which are α, ß and γ forms. In addition, chitin has a compact structure and strong intra and inters molecular hydrogen bonds [5] that may causes the insolubility in most of the organic solvents, thus limit it in many applications, especially in clinical field. Due to this co...

“…After 5 days DP reached 82% in a solid-state process [92]. Using P. aeruginosa F722 with crab shell wastes at 30 C, 92% DM and 63% DP after 7 days were reported [93]. The deproteinization and demineralization of crab shell waste using Serratia marcescens FS-3 reached 47% and 84% after 7 days.…”
