“…No significant influence of the NaOH concentration on the yield extraction has been shown (p ≥0.05). Our results are similar to those obtained by Ahing et al (2016) [12] and slightly lower than those obtained by Nouri et al [4]. Differences in yield extraction can be due to the difference of the extraction conditions, precisely, time and temperature of deacetylation [6].…”

“…Gelatin, a polypeptide extracted from fish skins, offers various functional properties such as film-forming, gelling and emulsifying properties and can be applied in several fields like food, pharmaceutical and cosmetic industry [2].On the other hand, chitosan, a polysaccharide derived from chitin can be extracted from crustaceans shells, especially shrimps, is widely studied for its excellent functional and biological properties, and has various applications in several fields such as wastewater treatment, food, pharmaceutical, textile and cosmetic industry [3].Therefore, the valorization of these by-products can represent an important eco-friendly alternative that allow, in addition to reducing the environmental impact, the enhancement of creativity, competitiveness and productivity of companies. Despite that extraction and characterization of these two biopolymers have been already studied by several authors all over the world [4][5][6], to the best of our knowledge, studies at national level are inexistent. Moreover, data obtained from other authors cannot be extrapolated due to the specificity and characteristics of each raw material.…”

Abstract. Fish and seafood processing industries generate large quantities of waste which are at the origin of several environmental, economic and social problems. However fish waste could contain high value-added substances such as biopolymers. This work focuses on optimizing the gelatin and chitosan extraction from tilapia fish skins and shrimp shells respectively. The gelatin extraction process was optimized using alkali acid treatment prior to thermal hydrolysis. Three different acids were tested at different concentrations. Chitosan was obtained after acid demineralization followed by simultaneous hydrothermal deproteinization and deacetylation by an alkali treatment with different concentrations of HCl and NaOH. The extracted gelatin and chitosan with the highest yield were characterized by determining their main physicochemical properties (Degree of deacetylation, viscosity, pH, moisture and ash content). Results show a significant influence of the acid type and concentration on the extraction yield of gelatin and chitosan, with an average yield of 12.24% and 3.85% respectively. Furthermore, the obtained physicochemical properties of both extracted gelatin and chitosan were within the recommended standard values of the commercial ones used in the industry.

“…It was also odorless and in a form of crystalline flakes. The characteristic of the chitosan produced from this study was similar to the chitosan obtained from previous studies which was slightly brownish to white and yellowish white and this indicates a good quality of chitosan was produced (Naznin, 2005;Nouri et al, 2016). …”

“…Other study which is done by Abdou et al (2008) the DDA value of chitosan obtained was up to 90% by performing the deacetylation in an autoclave, while Al Sagheer et al (2009) reported that the chitosan DDA obtained from shrimp shell waste in Arabian Gulf ranged from 88-94% by using traditional method. Nouri et al (2016) also obtained DDA value ranged from 71.02-82.20% for deacetylation using traditional method, while 79.01-88.60% for using microwave method. Besides, Alishahi et al (2011) also performed deacetylation by using microwave and obtained chitosan with DDA value ranged from 87.5 -93%.…”

“…However, this bio-waste which includes head and shell can produce value-added products such as chitosan which is derived from chitin that generally found in marine invertebrates, insect, and fungi and chitosan is easily formed into various semi-solid and solid structures under mild conditions (Szymanska and Winnicka, 2015). According to Nouri et al (2016) and Ning and Xi (2015), the shrimp waste contains protein (30-40%), calcium carbonate (30-50%) and chitin (20-30%).…”

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.

The aim of this study was to extract chitin and chitosan from shrimp shells by neutral protease-assisted microwave multiple heating (one, two, three, and four) treatment. The structure and physicochemical properties of chitosan were characterized by scanning electron microscopy (SEM) and Fourier infrared spectroscopy (FTIR). The dielectric properties of chitosan acetate solution were determined by using a PNA-L network analyzer, and the correlation between chitosan deacetylation degree and dielectric loss was further analyzed. The results show that the degree of deacetylation of chitosan increased from 84.9% to 90.8% with the increase in the number of microwave heating treatments. Furthermore, the chitosan prepared by multiple microwave heating was smoother. The dielectric constant of chitosan solution gradually decreases with the increase of frequency, and the dielectric loss first decreases and then increases. In addition, the dielectric loss of the chitosan solution increased with the degree of deacetylation of chitosan at 2450 MHz (R 2 > 0.99). Therefore, enzyme-assisted microwave extraction of chitosan can be used to obtain high-quality chitosan under the condition of increasing the number of heating treatments.
