“…The degree of deacetylation (DD%), described as the crucial factor determining the physicochemical behavior and biological functionality of chitosan [13], reached a value of 67.03 %. Our results are similar to those obtained by Tokatlı et al (2017) [14], but higher than those presented by Kumari et al (2015) [15], and lower than those obtained by Sagheer et al (2009) [16]. These variations may be affected by the different nature of raw material and the parameters of deacetylation process (time and temperature).…”

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.

“…[28][29][30][31][32][33][34][35] The use of chitin and chitosan in medicine is worth noticing. A unique complex of chitosan properties, its biocompatibility, biodegradability, and non-toxicity, along with high biological and sorption activity, makes this aminopolysaccharide one of the commercially available and ecologically safe polymers with high potential for use in medicine.…”

Background: One of the most prominent problems of surgery and dermatology is the rational treatment of pyoinflammatory diseases of skin and post-operative pyogenic complications. Objective: The aim of the study was to develop a scientific methodological approach to expansion of product range for treatment of infected wounds. Materials and Methods: Development of methodology for unbiased assessment of prospects of development of novel drug products for the treatment of infected wounds was performed using information analysis methods. Results: A systemic analysis of active pharmaceutical ingredients used in drug products for wound treatment depending on the wound healing phase allowed to discover the most widely used drug products. A comparative assessment of dosage forms used in infected wounds treatment showed that local wound healing medications were represented primarily by gels or hydrophilic/hydrophobic ointments.Conclusion: Taking obtained results into account, it is shown that the novel drug product for the treatment of infected wounds should be represented by a hydrophilic multicomponent composition, which includes immobilized proteolytic enzymes and polysaccharide complex of chitosan and alkylamidopropyldimethylbenzylammonium.
