“…The use of chitosan in food industry for food preservation has already been established (Vasilatos and Savvaidis 2013;Lee and Je 2013). Further, chitosan is an effective antimicrobial (Champer et al 2013), antioxidant (Yen et al 2008) and antifungal agent (Park et al 2008) which was an added advantage for intended functional food applications. Hence in our viewpoint, curcumin encapsulated in nanoassemblies generated by interactions of two different functional food ingredients might have offered added advantage to total nutritive quality of food material in addition to its increased preservative effect by antioxidant mechanism in aqueous system.…”

The supramolecular nano-assemblies formed by electrostatic interactions of two oppositely charged lipid and polymer have been made and used as nanocarriers for curcumin to address its bioavailability and solubility issues. These curcumin encapsulated nano-supramolecular assemblies were characterized with respect to their size (dynamic light scattering), morphology (TEM, SEM), zeta potential (Laser Doppler Velocimetry), encapsulation efficiency (EE), curcumin loading (CL) etc. Stability of the nano-assemblies was assessed at different storage times as a function of varying pH and temperature. The physicochemical characterization of nano-assemblies was performed using Fourier Transform Infra Red Spectroscopy (FT-IR) and Differential Scanning Calorimetry (DSC). The in-vitro antioxidant lipid peroxidation (TBARS), radical scavenging (DPPH, NO, H 2 O 2 , reducing power) activity assays of powdered curcumin and nanoencapsulated curcumin were performed. It was found that nano-encapsulated curcumin were roughly spherical in shape, presented high positive zeta potential (>30 mV), monodisperse (polydispersity index <0.3), amorphous in nature, stable in the pH range of 2-6 and have enhanced antioxidant potency in comparison to crystalline curcumin in aqueous media. In conclusion, the curcumin encapsulated nanocarriers system has great potential as functional food ingredient of natural origin.

“…Chitosan is an amino polysaccharide with antifungal effects derived from chitin by alkaline deacetylation. Chitin is the second most abundant polymer in nature after cellulose (25)(26)(27)(28)(29)(30) and has a safe biological profile for patients. It exhibits a therapeutic effect on diabetes along with cholesterol-lowering, woundhealing, antitumor, antifungal, and antimicrobial effects (31,32).…”

This study investigated the antifungal effects of low-molecular-weight chitosan solution onCandida albicans in denture stomatitis in comparison with nystatin suspension. This randomized, singleblind clinical trial included 40 patients diagnosed with denture stomatitis. Patients were divided into two groups, wherein one was treated with chitosan and the other with nystatin for 2 weeks. Changes in the erythematous area were recorded during and after treatment. A palatal smear was obtained for each patient before and after treatment to determine the number of blastospores and mycelia of C. albicans. The results were compared using the MannWhitney U test, revealing that the chitosan solution significantly decreased the erythematous surface area, burning sensation, time required for clinical improvement, and number of blastospores and mycelia. The antifungal efficacy of chitosan along with its inherent biocompatibility makes it a promising candidate for use as an antifungal mouthwash.

“…The similar study expresses that chitosan from Squilla mantis by-products showed effective inhibition to lipid peroxidation. Moreover, antioxidant activities are reported to be involved with chitosan and its derivatives, particularly in the exoskeleton and carapace of mud crab shell [29,30]. Hence, it is important to note that crab shell is made of polysaccharide which is chemically similar to plants cellulose.…”

“…Hence, it is important to note that crab shell is made of polysaccharide which is chemically similar to plants cellulose. Meanwhile, Yen et al [29] explained in their study that chitosan from crab shell is a good scavenger on hydroxyl radicals and has the ability to act as a chelating agent. In this case, scavenging activity of chitosan is ascribed based on the presence of free amino group that reacts with free radicals in order to form a stable macromolecular radical [31].…”

Mud crab from the genus Scylla is also known as mangrove crab, which has been well-accepted as a good source of protein.Recently, the antioxidant properties present in mud crabs have been reported to have a part in the protection of cells against free radicals. Meanwhile, numerous antimicrobial peptides from mud crabs have managed to be characterized through the display of antimicrobial activities against Gram-positive and Gram-negative bacteria. Hence, this paper is an effort to collect recent literatures on antioxidant and antimicrobial properties in every part of mud crabs which include muscle tissue, hemolymph, and crab shell. Moreover, the effort to understand the biological properties of mud crabs is important to enhance its production in aquaculture industry. Therefore, this review hoped to attract the attention of natural product researchers to focus on the potential therapeutic applications of mud crabs.
