Exploring the Chemical Composition, Antioxidant, and Antibacterial Properties of Helix aspersa Müller Flesh Crude Extract: A Comprehensive Investigation. ACS OMEGA 2024; 9:34754-34764. [PMID: 39157072 PMCID: PMC11325497 DOI: 10.1021/acsomega.4c04042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 07/21/2024] [Accepted: 07/23/2024] [Indexed: 08/20/2024]
Abstract
Snail flesh is a highly nutritious and easily digestible food commonly integrated into the human diet. In this study, snails belonging to the Helix aspersa Müller species were used to determine their chemical composition and evaluate the antioxidant and antibacterial activities of their flesh using successive maceration extractions with three solvents of different polarities. Biomolecules were analyzed spectrophotometrically, and their chemical compositions were determined by using gas chromatography coupled with mass spectroscopy. The antioxidant activity was assessed using three tests: DPPH, iron-reducing power test, and total antioxidant activity. The ethanol extract was found to be the most effective, with a high yield and high biomolecule content compared with other extracts. The extracts showed a significant amount of antioxidants, ranging from 3.14 to 7.04 mg AAE g-1 of dry matter, according to the total antioxidant activity assay. The DPPH scavenging capacity showed a reduction of the radical, with inhibitory concentrations ranging from 507.07 to 829.49 μg mL-1. In contrast, the iron-reducing power ranged from 67.98 to 424.74 μg mL-1. All of the strains studied responded favorably to the antimicrobial effects of H. aspersa extracts, with a zone of inhibition ranging from 8.48 to 15.53 mm. Additionally, at approximately 15 mg mL-1, the ethanolic extract had the lowest minimum inhibitory concentration against Pseudomonas aeruginosa. H. aspersa Müller flesh is rich in biomolecules with antioxidant and antibacterial activities, which could justify its use as a natural product and in therapeutic applications in the food industry.

Allapitchai JF, Pitchai A, Ramasamy P. Isolation and Free Radical Scavenging Ability of Linear Polysaccharides From Cuttlebone of Sepia prashadi. Cureus 2024; 16:e60163. [PMID: 38868279 PMCID: PMC11167503 DOI: 10.7759/cureus.60163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Accepted: 05/11/2024] [Indexed: 06/14/2024] Open
Abstract
Background This study aimed to isolate linear polysaccharides from Sepia prashadi cuttlebone with the objective of evaluating their ability to scavenge free radicals. By providing new natural components for pharmaceutical and functional food uses, this research advances our understanding of the potential health benefits of polysaccharides originating from marine sources and their antioxidant properties. Objective The objective of the study is to isolate a linear polysaccharide chitosan from Sepia prashadi cuttlebone (produced by the partial deacetylation of chitin), characterize its structure using fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD), and explore the isolated polysaccharide's free radical scavenging potential. Material and methods Linear polysaccharide, chitosan was extracted chemically from Sepia prashadi from cuttlebone waste, by demineralization and deproteinization.Chemical characterization of chitosan was performed using Fourier transform infrared spectroscopy (FTIR) in the 400-4000 nm frequency range. The surface characteristics of chitosan, such as its texture, porosity, and roughness, are visible in scanning electron microscopy (SEM) images. X-ray diffraction (XRD) can be utilized to examine how chitosan interacts with other substances, such as medications or nanoparticles, by analyzing alterations in the diffraction pattern during complexation or formulation. Scavenging ability was demonstrated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide radical, and chelating ability of ferrous ions assays. Results Chitosan is formed from chitin. The extraction yields of chitosan and chitin were 78% and 39%, respectively. High levels of superoxide radical scavenging activity (76.1%), DPPH radical scavenging activity (62.1%) and chelating activity (127.5% at 100 g/mL) were observed in cuttlebone chitosan. Sepia prashadi showed an increased antioxidant activity in chitosan. Conclusion The goal of this study was to determine the effectiveness of various extraction techniques for preserving the antioxidant activity of chitosan derived from Sepia prashadi cuttlebone waste. The maximum scavenging activity was demonstrated by both the chelating ability and antioxidant activity. Considering that this raw material is derived from renewable resources and produces highly valued chemicals, it is a profitable endeavor.

Abstract
There is a stable growth in aquaculture production to avoid seafood scarcity. The usage of eco-friendly feed additives is not only associated with aquatic animal health but also reduces the risk of deleterious effects to the environment and consumers. Aquaculture researchers are seeking dietary solutions to improve the growth performance and yield of target organisms. A wide range of naturally derived compounds such as probiotics, prebiotics, synbiotics, complex carbohydrates, nutritional factors, herbs, hormones, vitamins, and cytokines was utilized as immunostimulants in aquaculture. The use of polysaccharides derived from natural resources, such as alginate, agar, laminarin, carrageenan, fucoidan, chitin, and chitosan, as supplementary feed in aquaculture species has been reported. Polysaccharides are prebiotic substances which are enhancing the immunity, disease resistance and growth of aquatic animals. Further, chitin (CT), chitosan (CTS) and chitooligosaccharides (COS) were recognized for their biodegradable properties and unique biological functions. The dietary effects of CT, CTS and COS at different inclusion levels on growth performance, immune response and gut microbiota in aquaculture species has been reviewed. The safety regulations, challenges and future outlooks of CT, CTS and COS in aquatic animals have been discussed in this review.

Abstract
Over the last years, chitosan has demonstrated unparalleled characteristics for regenerative medicine applications. Beside excellent antimicrobial and wound healing properties, this polysaccharide biopolymer offers favorable characteristics such as biocompatibility, biodegradability, and film and fiber-forming capabilities. Having plentiful active amine groups, chitosan can be also readily modified to provide auxiliary features for growing demands in regenerative medicine, which is constantly confronted with new problems, necessitating the creation of biocompatible, immunogenic and biodegradable film/scaffold composites. A new look at the chitosan composites structure/activity/application tradeoff is the primary focus of the current review, which can help researchers to detect the bottlenecks and overcome the shortcomings that arose from this intersection. In the current review, the most recent advances in chitosan films and scaffolds in terms of preparation techniques and modifying methods for improving their functional properties, in three major biomedical fields i.e., tissue engineering, wound healing, and drug delivery are surveyed and discussed.

Abstract
The objective of this study is to innovatively evaluate the biochemistry performance of α-chitosan from Portunus trituberculatus shell and β-chitosan from Illex argentinus squid gladius by using the weighted composite index method, and provide a theoretical basis for better development and utilization of chitosan biomedical materials. To build a composite evaluation system, seven key indicators, including molecular weight (Mw), deacetylation degree (DD), water binding capacity (WBC), fat binding capacity (FBC), thermal stability (TS), primary structure and secondary structure, which significantly affect chitosan biochemical characteristics, were determined and analyzed. The viscosity average Mw of chitosan was in the range of 22.5–377.1 kDa, and the DD was 83.4–97.8%. Thermogravimetric (TG) and differential scanning calorimetry (DSC) analyses of commercial chitosan (CS), crab chitosan (CSC) and squid chitosan (CSS) showed a downward trend in TS, while WBC and FBC showed an obvious upward trend. FT-IR had a similar profile in peak shape, but the peak position slightly shifted. CD indicated that chitosan maintained the double helix structure and multiple secondary structural elements. The composite weighted index values of CS, CSC and CSS were 0.85, 0.94 and 1.31 respectively, which indicated that the CSS biochemistry performance was significantly better than CSC, and β-chitosan has great potential in biomedical materials.

Abstract
β-chitin was isolated from marine waste, giant Humboldt squid Dosidicus gigas, and further converted to nanofibers by use of a collider machine under acidic conditions (pH 3). The FTIR, TGA, and NMR analysis confirmed the efficient extraction of β-chitin. The SEM, TEM, and XRD characterization results verified that β-chitin crystalline structure were maintained after mechanical treatment. The mean particle size of β-chitin nanofibers was in the range between 10 and 15 nm, according to the TEM analysis. In addition, the β-chitin nanofibers were converted into films by the simple solvent-casting and drying process at 60 °C. The obtained films had high lightness, which was evidenced by the CIELAB color test. Moreover, the films showed the medium swelling degree (250-290%) in aqueous solutions of different pH and good mechanical resistance in the range between 4 and 17 MPa, depending on film thickness. The results obtained in this work show that marine waste can be efficiently converted to biomaterial by use of mild extractive conditions and simple mechanical treatment, offering great potential for the future development of sustainable multifunctional materials for various industrial applications such as food packaging, agriculture, and/or wound dressing.

Abstract
Artemisia sphaerocephala Krasch (ASK) is an important member of Compositae (Asteraceae) family. Its seeds have been widely used as traditional medicine and to improve the quality of food. Water soluble and water insoluble polysaccharides are found in the seeds of this plant. Research has been conducted on the extraction of polysaccharides, their modification and determination of their structure. To date different techniques for extraction purposes have been applied which are reviewed here. Antioxidant, antidiabetic, anti-obesogenic, antitumor, and immunomodulatory activities have been explored using in vivo and in vitro methods. Moreover, these polysaccharides have been used as packaging material and as a sensing component for monitoring the freshness of packaged food. Some experimental results have shown that the quality of foods is also improved by using them as a food additive. We have also indicated some of the potential areas that are needed to be explored.

Abstract
The bacterial infections have always a serious problem to public health. Scientists are developing new antibacterial materials to overcome this problem. Polysaccharides are promising biopolymers due to their diverse biological functions, low toxicity, and high biodegradability. Chitin and chitosan have antibacterial properties due to their cationic nature, while cellulose/bacterial cellulose does not possess any antibacterial activity. Moreover, the insolubility of chitin in common solvents, the poor solubility of chitosan in water, and the low mechanical properties of chitosan have restricted their biomedical applications. In order to solve these problems, chemical modifications such as quaternization, carboxymethylation, cationization, or surface modification of these polymers with different antimicrobial agents, including metal and metal oxide nanoparticles, are carried out to obtain new materials with improved physiochemical and biological properties. This mini review describes the recent progress in such derivatives and composites with potential antibacterial applications.

Abstract
Chitin is the second most abundant polysaccharide in biomass after cellulose and the term chitosan usually refers to a family of polymers obtained after chitin deacetylation. The aim of this work was the preparation and the characterization of chitin and chitosan from the gladius (pen) of the European squid (Loligo vulgaris). A high level of deproteinization (more than 80%) was recorded using Alcalase® with an enzyme/protein ratio of 10U/mg. The demineralization of the gladius was completely achieved within 8h at room temperature in HCl. 13C NMR, FTIR, and XRD diffractograms of prepared chitin and chitosan were taken and then degree of deacetylation of chitosan was calculated using 13C CP/MAS-NMR Spectroscopic. Further, in vitro antioxidant capacity of chitosan was evaluated on 1,1-diphenyl-2-picrylhydrazyl method (IC50=3.2mgmL-1) and the β-carotene bleaching assay (IC50=3.3mgmL-1). Antimicrobial activity was also investigated and assays indicated that prepared chitosan exhibited marked inhibitory activity against all microbial strains tested. Additionally, chitosan was tested such as clarifying agent for apple juice and showed powerful clarification capability, without affecting nutritional value. Furthermore, the results suggested that prepared chitosan could be used as alternative additive in pharmaceutical preparations and food industry.

Abstract
Chitosan is a commercially available derivative of
chitin that has been extensively studied for its antimicrobial properties. In
order to improve the water solubility and its biological activity, the chemical
modification or derivatisation is attempted. In the present investigation, the
chitosan prepared from the cuttlebone of Sepia kobiensis
was being chemically modified by reacting it with orthophosphoric acid so as to
obtain phosphorylated chitosan. Then the chitosan and phosphorylated chitosan
were structurally characterized through FT-IR spectroscopy. Further the
antibacterial activity of chitosan and phosphorylated chitosan was tested
against clinically isolated human pathogens (Gram-positive:
Streptococcus sp., Streptococcus
pneumoniae and Staphylococcus aureus and
Gram-negative: Escherichia coli, Vibrio
cholerae, V. alginolyticus,
Vibrio parahaemolyticus, Pseudomonas
aeruginosa, Klebsiella pneumoniae,
Salmonella sp. and Proteus
vulgaris) by well diffusion method and the Minimum Inhibitory
Concentration (MIC) was also calculated. The results of the present study
suggests that the chitosan and phosphorylated chitosan has concentration
dependent antibacterial activity with variation against several pathogenic human
pathogenic bacterial strains which indicates their possible use as antibacterial
agents.
