“…The degree of deacetylation (DDA) of chitosan ranges from 50 to 100% depending on the source (Trung & Bao, 2015), preparation method (demineralization, deproteinization, and deacetylation conditions) (Cho, No, & Meyers, 1998;Hossain & Iqbal, 2014;Lertsutthiwong, How, Chandrkrachang, & Stevens, 2002;Sagheer et al, 2009), and the reversal of the process steps (Fernandez-Kim, 2004). The DDA of chitosan influences both its physicochemical properties (Cho et al, 1998;Hossain & Iqbal, 2014;Tolaimate et al, 2000) and its biological properties (Matsugo et al, 1998;Raafat & Sahl, 2009;Rajalakshmi, Krithiga, & Jayachitra, 2013;Trung & Bao, 2015;Wan, Xu, Sun, & Li, 2013). Naznin (2005) stated that the optimum conditions for chitosan production from shrimp shell in Bangladesh were observed at using 30% HCI for demineralization, 1.5 N NaOH for deproteinization, 50% NaOH for deacetylation and resulted in chitosan yield of 8.7%.…”

The objectives of this study were to optimize and evaluate chitin and chitosan production conditions from shrimp waste using the response surface methodology and to characterize obtained chitosans. The effects of demineralization and deproteinization conditions on chitin production and deacetylation conditions on chitosan production were investigated. Optimum conditions for chitin production were observed at using 0.73 mol/L hydrochloric acid for 132.61 min at room temperature for demineralization and 0.95 mol/L sodium hydroxide for 75.65 min at 60.49 °C for deproteinization. The obtained chitin was used to optimize chitosan production and two different chitosans were defined as chitosan‐1 and chitosan‐2. Chitosan‐1 was obtained by deacetylation with 40% sodium hydroxide at 120 °C for 300 min, and Chitosan‐2 was obtained by deacetylation with 50% sodium hydroxide at 100 °C for 720 min. The obtained chitosans were characterized by their degree of deacetylation, molecular weight, viscosity, mineral content, whiteness index, and scanning electron microscope micrographs. Practical applications Chitosan, carbohydrate‐based polymer, is derived from crustacean shells. The extraction process of chitin and chitosan from shrimp wastes sourced of different sources needs optimization to obtain high yield chitosan without impurity. Although the production of chitosan by chemical method has been studied earlier, this is the first report on extraction of chitin and chitosan from shrimp waste from the Marmara Sea in Turkey. Shrimp waste from Marmara Sea in Turkey, which has no economic value, can be successfully converted into chitosan. The effective utilization of these wastes would not only eliminate waste but also contribute to the economy as value‐added products.

“…• DPPH test, reducing power and lipid peroxidation inhibition activity) was also shown in the work of Trung and Bao (2015) for the chitosan with DD 87% and no molecular weight specification. Similar, higher-molecular forms of chitosan (HMW) did not show activity as a primary antioxidants in the work of Pasanphan et al (2010) and this lack of activity can be correlated with strong intra-and intermolecular hydrogen bonds resulting in the absence of hydrogen atoms that would be donated to break free radicals chain oxidation reactions.…”

ABSTRACT:Growing consumer demand for the food without chemical preservatives focused significant extent of research in the direction of finding natural compounds that can be used in food preservation. In this context, natural substances with strong antimicrobial and antioxidant properties, like essential oils, as well as natural biopolymers, particularly draw attention. Natural biopolymers can serve as carriers of the active components, such as essential oils in order of their sustained release to the food during storage, and may themselves exhibit activity in protecting foods from oxidation and/or microbial spoilage. Chitosan has been extensively studied as semi-natural polymer with expressed bioactive properties. While antimicrobial activity of chitosan solution in different acids has been confirmed towards different bacteria, yeasts and moulds, reports concerning intensity, underlying machanism and different factors afecting antioxidant activity of chitosan vary through the available literature. This paper presents a review in the field of antioxidative activity of chitosan with different properties, as well as chitosan based biopolymer films in order to clarify this aspect of chitosan bioactivity and confront different reports found in the literature.

“…Antioxidant properties of chitosan were also investigated. Trung and Bao studied the molecule extracted from L. vannamei [104]. Their study suggested that the antioxidant effect observed was based on the free radical scavenging activity and the reduction of potency.…”

The oceans harbor a great diversity of organisms, and have been recognized as an important source of new compounds with nutritional and therapeutic potential. Among these compounds, carbohydrate-based compounds are of particular interest because they exhibit numerous biological functions associated with their chemical diversity. This gives rise to new substances for the development of bioactive products. Many are the known applications of substances with glycosidic domains obtained from marine species. This review covers the structural properties and the current findings on the antioxidant, anti-inflammatory, anticoagulant, antitumor and antimicrobial activities of medium and high molecular-weight carbohydrates or glycosylated compounds extracted from various marine organisms.
