“…The highest FBC% was recorded for chitosan of P. monodon (644.15%, 556.53% and 565.21% regard to coconut oil, sunflower oil and soybean oil respectively), were similar to the values reported by No et al (2000). Merzendorfer (2006) reported that changing the sequence of isolation steps as demineralization, de-proteinization and de-acetylation results in an increase in FBC than when deproteinization is done prior to demineralization.…”

“…Earlier studies by several authors (Cho et al 1998;No et al 2000;Trung et al 2006) have demonstrated that the physicochemical characteristics of chitosan affect its functional properties, which also differ according to crustacean species and preparation methods. Several procedures have been developed and proposed by many researchers over the years for preparation of chitosan from different crustacean shell wastes (Islam et al 2011).…”

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.

“…Water and fat binding capacities of different commercial chitosans were reported as 458-805% and 314-535%, respectively, by Cho, No, and Meyers (1998). WBC and FBC of six commercial chitosan products observed by No, Lee, and Meyers (2000) were in the range of 355-611% and 217-477%, respectively. The WBC (492.67%) and FBC (383.04%) of commercial chitosan in the present study were compatible to those reported by Cho et al (1998) and No et al (2000).…”

a b s t r a c tIn this study, chitosan was extracted from Metapenaeus stebbingi shells. In order to determine physicochemical characteristics of the extracted chitosan, the yield, moisture and ash contents, degree of deacetylation, molecular weight, water and fat binding capacities, apparent viscosity and colour properties were measured using a variety of techniques including Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction. In addition, the physicochemical characteristics of the chitosan extracted from M. stebbingi shells were compared to commercial chitosan. The degree of deacetylation was calculated by the titration method and elemental analysis. The molecular weight was determined by viscosimetric methods. The results of the study indicate that shrimp shells are a rich source of chitosan as 17.48% of the shell's dry weight is consisted of this material. Extracted chitosan exhibited a lower molecular weight, higher degree of deacetylation, higher viscosity and higher water and fat binding capacities compared to the commercial chitosan.

Modification of chitosan by p-t-butylcalix [4]arenes has been conducted using a nucleophilic subtitution reaction between chitosan, p-t-butylcalix [4]arenes and N,N-diisopropyl carbodiimide (DIC) in reagent dichlorometane at room temperature and under nitrogen atmosphere. Analysis structure of the chitosan-p-t-butylcalix [4]arenes is determined with spectrophotometer Fourier Transform Infra Red (FTIR) and X-ray diffraction. The melting point, surface area and morphological analysis are also conducted on the prepared materials.The prepared chitosanp-t-butylcalix[4]arenes is white brown powder with melting point of 238 ºC. The FTIR spectrum shows a peak at 3346.50 cm -1 that indicates the presence of the N-H bonds of secondary amine. The diffraction patterns shows the presence of charge and shift in 2θ.It indicates that the modification proceed successfully. The result of surface area analysis shows that chitosan-p-t-butylcalix [4]arenes is macroporous material with average of pore radius of 673.6 Å and the surface area of 16.352 m 2 /g. SEM analysis shows that chitosan-p-t-butylcalix[4]arenes also confirm that the materials has porous surface.
