“…De-mineralization usually results in products having 31-36% of ash (Tsai and Hwang 2004). The fresh shrimp shells have 32.27% of ash (Hossain and Iqbal 2014). A high quality grade chitosan should have less than 1% of ash (Hossain and Iqbal 2014).…”

Shell waste produced by the sea food industry is one of the most significant problems contributing for environmental and health hazards. The most frequent method employed for disposal of these waste is burning which is environmentally costly due to low burning capacity of shells. In such a scenario, conversion of shrimp shell waste to chitosan, a commercially valuable product with a myriad of uses, could serve as an effective mode of shell remediation. Chitosan was obtained from shellfish waste by deproteination, demineralization, discoloration and deacetylation processes. It was characterized using Fourier Transformed Infra-Red (FT-IR) spectroscopy. The physico-chemical parameters such as moisture content, ash content, solubility, N-content, water binding capacity (WBC), fat binding capacity (FBC) and degree of deacetylation (DD) were analysed to compare the extracted six chitosan samples from Penaeus monodon, Portunus pelagicus, Portunus sanguinolentus, Scylla serrata, Panulirus homarus and Panulirus versicolor. The ranges for percentage yield, moisture content, ash content, N-content, percentage solubility, and WBC were 14.53±0.47%-34.13±3.72%, 3.16±1.77%-7.52±1.11%, 0.65±0.23%-53.52±5.65%, 2.02±0.03% -6.16±0.10%, 15.28±0.62% -47.91±5.15%, and 262.94±20.88% -600.61±58.11% respectively. FBC varied approximately from 250% to 650% in coconut oil, sunflower oil and soybean oil. Among the six chitosan samples, P. monodon was the most suitable crustacean exoskeleton waste from fish processing industry to isolate chitosan due to the fact that in the processing of shrimps for human consumption, 40 -50 % of the total mass is discarded as waste and high quality of chitosan extracted. Therefore, there is a high possibility of extracting good quality chitosan using exoskeleton waste of Penaeus monodon.

Polymeric scaffolds produced by cryogelation technique have attracted increasing attention for tissue engineering applications. Cryogelation is a technique which enables to produce interconnected porous matrices from the frozen reaction mixtures of polymers or monomeric precursors. Chitosan is a biocompatible, biodegradable, nontoxic, antibacterial, antioxidant, and antifungal natural polymer that is obtained by deacetylation of chitin, which is mostly found in the exoskeleton of many crustaceans. In this study, chitin was chemically isolated from the exoskeleton of blue crab (Callinectes sapidus). Callinectes sapidus samples were collected from a market, as a waste material after it has been consumed as food. Demineralization, deproteinization, and decolorization steps were applied to the samples to obtain chitin. Chitosan was prepared from isolated chitin by deacetylation at high temperatures. The chemical composition of crab shell, extracted chitin and chitosan were characterized with FTIR analysis. Moreover, in order to determine the physicochemical and functional properties of the produced chitosan, solubility, water uptake, and oil uptake analysis were performed. Chitosan cryogel scaffolds were prepared by crosslinking reaction at cryogenic conditions at constant amount of chitosan (1%, w/v) with different ratios of glutaraldehyde (1, 3, and 6%, v/v) as crosslinker. The chemical structure of the scaffolds were examined by FTIR. Also, the water uptake capacity of scaffolds have been determined. Collectively, the results suggested that the characterized chitosan cryogels can be potential scaffolds to be used in tissue engineering applications.

“…2). Previous study which was done by Patria (2013) reported that the solubility achieved was 17.43 % to 95.29 % with average of 57.52 % at different deacetylation temperature 60, 70, 80 and 90 0 C whereas another study also showed the solubility obtained was ranged from 48.30 % to 97.65 % by performing deacetylation once at temperature 65 0 C but using different concentration of NaOH (30, 40, 50, 60 %) (Hossain and Iqbal, 2014). There is no literature reported on the solubility of deacetylated twice of chitosan yet, however by comparing the solubility of this study to previous studies which has been done, is shows that by repeating the deacetylation process twice, it increases the amount of amino groups (NH2) in the chitosan polymer chain thus increasing the solubility of chitosan.…”

“…The difference of group in the position C-2 of chitosan which is NH2 instead of hydroxyl group (OH) for cellulose makes chitosan can easily form positive ionic charge which can increases the ability to chemically bind with negatively charged compounds such as fats, lipids, cholesterol, metal ions, proteins, and macromolecules (Hossain and Iqbal, 2014).…”

Chitosan, a versatile natural polymer is an amino polysaccharide prepared by processing shrimp shell waste which involved deacetylation of chitin. To obtain high degree of deacetylation (DDA), several parameters should be performed during alkaline treatment. The present study was undertaken at different time of soaking treatment (once and twice) and temperature (60 o C and 80 o C) to optimize the deacetylation process to produce chitosan with high solubility and degree of deacetylation. It was observed that the highest solubility and degree of deacetylation were obtained when deacetylation process was repeated twice and temperature of 80 o C, with 99.48% and 97.63%, respectively. It can be concluded that by repeating the deacetylation twice with the support of heating treatment, a better quality of chitosan with higher solubility and degree of deacetylation can be produced.
