Antimicrobial \u0026 edible chitosan film applied for foodChitosan for biodegradable materials -
Low cost of production, chemical resistance as well as mechanical properties are the factors affecting the success of synthetic polymers as biodegradable materials. The resulting films were thin, homogenous, and uniform. Pure chitosan with the incorporation of natural extract showed greater scavenging activity Nwabor et al.
The resulting films of 1. However, a greater proportion of Ag nanoparticles and 1. Regarding the antimicrobial activity of the films, pure chitosan and PVA films did not present any antimicrobial effects but when Ag nanoparticles were incorporated, there were The study also evaluates the shelf life of chicken sausage wrapped with the films.
the results showed that film did not show any sign of spoilage and remained visually intact while 1. A study to develop films to keep the freshness of fish was conducted by Vadivel et al. Fathima et al.
Likewise, a decrease in elongation was detected as the concentration of NCS increased which occurred due to weak interfacial adhesion between PLA and NCS.
The oxygen transmission rate was lowest in 0. In contrast, the water vapor transmission rate was highest in 0. Haghighi et al. These results were obtained as functional groups of LAE disturbed the interaction between the polymer chains.
This is due to inability of LAE to create a continuous and cohesive matrix. UV barrier analysis demonstrated that reduced UV light transmittance was observed in films with increasing LAE concentration. Exceeding the critical concentration of LAE can result in the formation of aggregates that are large enough to scatter light and thus disrupt transmission.
jejuni only. Conventional plastic packaging has labeled the food industry as a source of pollution with a number of social and environmental concerns due to insufficient waste management systems and non-biodegradability. Thus, biodegradable and biobased materials have received considerable attention to overcome these problems recently.
Chitosan adoption as packaging material shows benefits in mitigating these environmental concerns, despite some downside in terms of barrier and mechanical properties as well as the production costs.
Blended films of chitosan with other synthetic or natural polymers such as polyvinyl alcohol, carboxymethyl cellulose, methylcellulose, contribute towards the enhancement of various physico-chemical properties including its mechanical and barrier properties. The antimicrobial and antioxidant properties of chitosan-based films could contribute towards developing a functional food packaging against microbial and oxidative degradation.
This approach may prove promising for future innovative of food packaging design as it will replace the existing plastic packaging materials with those that can provide equal or better properties than synthetic polymers.

Keywords: Chitosan, Biodegradable film, Food packaging, Biopolymer. MATERIALS AND METHODS This review article was based upon searches of the National Center for Biotechnology NCBI , MEDLINE, Google Scholar, and Science Direct databases. FEATURES AND POTENTIAL OF CHITOSAN Chitosan is one of the most abundant natural polymers.
Antimicrobial Properties of Chitosan Antimicrobial activity of chitosan against Gram-positive and Gram-negative bacteria as well as fungi has drawn attention for potential use as a natural preservative for food.
Antioxidant Properties of Chitosan Antioxidant properties are one of the major properties of active packaging, which is important to extend the shelf life of food products.
Direct Casting Method The Direct casting method is the simplest and widely use method for the development of biopolymer films. Melt-extrusion Methods This method is another widely developed method in producing chitosan-based active packaging films.
CHITOSAN FILMS. Pure Chitosan-based Films Pure chitosan films have been developed by few researchers without the addition of other polymers but still include additives such as plasticizers, dilute acids or emulsifiers.
Moisture content MC , transparency value T , water vapor permeability WVP , oxygen permeability OP , tensile strength TS , and elongation at break EB of low molecular weight LMw and high molecular weight HMw chitosan-based films.
Adapted from Leceta, et al. Blended Chitosan Films A blend film is a combination of at least two compatible polymers or copolymers that are often developed in order to improve the physical properties of the films. Chitosan and Natural Biopolymers Blends A blend of chitosan with other natural biopolymers such as polysaccharides and proteins can enhance the functional properties of chitosan-based films.
Chitosan and Polysaccharides blend films A study reported that chitosan can be blended with polysaccharides such as starch, pectin, xanthan gum, carrageenan, xylan alginate, cellulose and its derivatives.
Chitosan and Protein blend films Proteins have been used in the development of biodegradable films and the sources or protein can be animal such as collagen, gelatin, casein, etc.
Chitosan and Synthetic Polymers blend films Blending of chitosan with synthetic polymers such as polyvinyl alcohol PVA , polyvinyl pyrrolidone PVP or polylactic acid PLA has been widely studied for their benefits on mechanical, physical, and biological properties of the blended films.

The overwhelming demand for plastics results in overproduction of plastics especially ,aterials or non-biodegradable plastics. Autophagy and neurodegeneration, this has given Diabetic retinopathy risk reduction to environmental concerns due to the addition of plastic waste in the environment where they may harm human, animals, and ecosystem. Due to this, the adoption of alternative sustainable packaging materials has gained more attention among the researchers and industries in developing biodegradable films in order to reduce plastic pollution. Chitosan is utilized for the formation of biodegradable films. Chitosan that is derived from chitin, is the second most abundant biopolymer after cellulose. Three soil-inhabited organsims, Cor marcescens, Pseudomonas CihtosanAutophagy and neurodegeneration Beauveria bassiana were able to Chiitosan chitin and chitosan in prepared Autophagy and neurodegeneration Gut Health Supplement PE-chitosan films after eight Chitosan for biodegradable materials of incubation at 25°C in Post-workout recovery basal medium containing no biodegrxdable of carbon or nitrogen. In soil placed in the lab, The weight of controls, polyethylene filmsremained mainly stable during the incubation period. Both PE-chitin and PE-chitosan films degraded at a higher rate than the commercial starch-based film in a soil environment indicating the potential use of chitin-based films for the manufacturing of biodegradable packaging materials.
