“…Preconditioned exoskeleton was demineralized using 1% HCl of four times of its quantity. The samples were allowed to soak for 24 h to remove the minerals, mainly calcium carbonate as described by Trung et al (2006). De-proteinization of the demineralized shell samples was carried out as described by No and Meyers (1992).…”

“…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.

“…To dissolve minerals from the centrifuged residue, 600 ml of 1% hydrochloric acid was added and the residue placed in a rotor shaker (Sanyo electric company limited, Japan) rotating at 40 rpm for 24 h at room temperature (Trung et al, 2006). The content was then subjected to centrifugation and the liquid part disposed while the remaining residue was treated with 500 ml of 2% boiling sodium hydroxide for 1 h to decompose albumin (Puvvada et al, 2012).…”

House cricket is currently introduced for scaled-up production in farming systems in Kenya and other parts of the world, as an alternative source of animal proteins. The aim of this study was to assess the nutritional composition in farmed cricket as influenced by age in order to ascertain the optimal harvesting time for possible utilization of crickets in improving child nutrition in Kenya. Sampling was carried out between weeks 4 and 13. The moisture content was analysed by drying method, chitin by sodium hydroxide digestion, protein content by estimation of total nitrogen, crude fat by soxhlet extraction method, ash by muffle furnace incineration, available carbohydrates by subtraction, and energy by calculation method. The crude protein mean ranged from 36.00 to 60.00 g/100 g, chitin 2.20 to 12.40 g/100 g, total lipids 12.00 to 25.00 g/100 g, over the 13 weeks period. Minerals concentration was optimum at week 9, with magnesium 1.30 to 11.30 mg/100 g, calcium 1.40 to 19.70 mg/100 g, and zinc 0.20 to 16.60 mg/100 g. Findings from this study indicate that farmed cricket would be best harvested between weeks 9 and 11, when the protein and mineral content is optimum. Nutrients available in farmed crickets show that farmed crickets can be used in child food ingredients to improve child nutrition.

“…The samples were treated in two different concentrations of NaOH where, the higher concentration (4%) is used for chitin preparation [14,15] . Further at room temperature the shells were subjected to demineralization using 1% HCl where, the minerals (mainly calcium carbonate) are removed [16] . The demineralization process was preceded by treating the samples with 50 ml of a 2% NaOH solution to decompose the albumen into water soluble amino acids.…”

Anita, et al.: Discerning the Proficiency of Chitosan as a Competent Brain Drug CarrierBiopolymer such as chitosan is more favoured as a drug carrier in particular to the brain due to its potential to cross the blood brain barrier. This study is a comparative assessment of the extraction of chitosan from natural sources such as mushroom, crab and shrimp using alkali method pursued by physicochemical assays that surmise the excellence of the biopolymer in permeating a central nervous system drug. Commercially, chitosan extracted from crustaceans have been widely used but this study revealed that mushrooms are also a good source for chitosan. An in silico assay enumerates the structural affiliation of the polymer and its binding efficiency. Molecular docking study facilitates to attest the brain targeting efficiency of chitosan on disparity with sodium alginate against the efflux permeability glycoprotein furnishing minimum binding affinity energy values of -37.2 k cal/mol. The pharmacologically significant descriptors propose a low solubility that avoids the untargeted discharge of drug. Chitosan extracted from a rich protein source such as mushroom in a mild alkaline condition with a high degree of deacetylation has freer amine groups can act as a drug by itself and can readily bind with a drug as a carrier. The synchronised work of biopolymer extraction with that of in silico analysis can further take chitosan as a lead compound for brain drug development and targeting studies.
