“…Nanochitin has also been incorporated into edible films for food preservation. Heidari et al produced thin chitin nanofiber films and nanocomposites containing biodegradable polymers with chitin nanofibers as the base [ 96 ]. Nanofiber/polyvinyl alcohol, nanofiber/gelatin, and nanofiber/thermoplastic starch films showed improved tensile strength, and greater water vapour permeability compared to pure nanofiber films [ 96 ].…”

Crustacean shells are a sustainable source of chitin. Extracting chitin from crustacean shells is ongoing research, much of which is devoted to devising a sustainable process that yields high-quality chitin with minimal waste. Chemical and biological methods have been used extensively for this purpose; more recently, methods based on ionic liquids and deep eutectic solvents have been explored. Extracted chitin can be converted into chitosan or nanochitin. Once chitin is obtained and modified into the desired form, it can be used in a wide array of applications, including as a filler material, in adsorbents, and as a component in biomaterials, among others. Describing the extraction of chitin, synthesis of chitosan and nanochitin, and applications of these materials is the aim of this review. The first section of this review summarizes and compares common chitin extraction methods, highlighting the benefits and shortcomings of each, followed by descriptions of methods to convert chitin into chitosan and nanochitin. The second section of this review discusses some of the wide range of applications of chitin and its derivatives.

“…Accordingly, packaging films can control pathogens and improve the quality and shelf life of food by acting as carriers of antimicrobial, antioxidant, and active compounds [48]. The use of nanofibers in food packaging may include different topics as presented in Table 5, which focused on using nanofibers for active-intelligent food packaging [113,120,122], as an active food packaging system [97], nanofibers containing biodegradable polymers [121], nanofibers for food freshness indicators [113], cellulose-based hydrophobic materials for food packaging [123], nanofibers for electrochemical DNA biosensors [124], and functionalized nanomaterials driven antimicrobial food packaging [117].…”

“…Several advantages of PVA were reported as excellent film-forming, adhesive, and emulsifying properties, which could be used in different industries through its potential as an agent for sizing of textile, an adhesive of paper, and soluble packaging films [46]. However, some limits in PVP usage were also reported, including its high cost, poor moisture barrier, and low biodegradation rate, which need to modify PVA using other polymers (such as starch and gelatin) and nanoparticles [121]. Due to the low mechanical strength of the biodegradable polymers alone obtained from PVP, some materials are needed to be inserted to improve these properties of biodegradable plastic [46].…”

Sustainable Applications of Nanofibers in Agriculture and Water Treatment: A Review

Natural fibers are an important source for producing polymers, which are highly applicable in their nanoform and could be used in very broad fields such as filtration for water/wastewater treatment, biomedicine, food packaging, harvesting, and storage of energy due to their high specific surface area. These natural nanofibers could be mainly produced through plants, animals, and minerals, as well as produced from agricultural wastes. For strengthening these natural fibers, they may reinforce with some substances such as nanomaterials. Natural or biofiber-reinforced bio-composites and nano–bio-composites are considered better than conventional composites. The sustainable application of nanofibers in agricultural sectors is a promising approach and may involve plant protection and its growth through encapsulating many bio-active molecules or agrochemicals (i.e., pesticides, phytohormones, and fertilizers) for smart delivery at the targeted sites. The food industry and processing also are very important applicable fields of nanofibers, particularly food packaging, which may include using nanofibers for active–intelligent food packaging, and food freshness indicators. The removal of pollutants from soil, water, and air is an urgent field for nanofibers due to their high efficiency. Many new approaches or applicable agro-fields for nanofibers are expected in the future, such as using nanofibers as the indicators for CO and NH3. The role of nanofibers in the global fighting against COVID-19 may represent a crucial solution, particularly in producing face masks.

“…An adequate cohesion between the polymer and filler components increases the values of E, σ max , and heat resistance, and improves the shear resistance, exfoliation, and corrosion resistance [ 55 ]. Different biodegradable polymers reinforced with chitin nanofiber showed higher tensile strength and lower elongation at break values [ 56 ].…”

Polymeric nanocomposites have received significant attention in both scientific and industrial research in recent years. The demand for new methods of food preservation to ensure high-quality, healthy foods with an extended shelf life has increased. Packaging, a crucial feature of the food industry, plays a vital role in satisfying this demand. Polymeric nanocomposites exhibit remarkably improved packaging properties, including barrier properties, oxygen impermeability, solvent resistance, moisture permeability, thermal stability, and antimicrobial characteristics. Bio-based polymers have drawn considerable interest to mitigate the influence and application of petroleum-derived polymeric materials and related environmental concerns. The integration of nanotechnology in food packaging systems has shown promise for enhancing the quality and shelf life of food. This article provides a general overview of bio-based polymeric nanocomposites comprising polymer matrices and inorganic nanoparticles, and describes their classification, fabrication, properties, and applications for active food packaging systems with future perspectives.
