“…Chitosan is a characteristic polymer that stands out from other biopolymers (e.g., collagen, elastin, and more) thanks to its abundance as raw material, the high solubility in acidic aqueous mediums (pH < 4), and its antimicrobial properties conducted by the protonation of the amino group [76]. Thus, we can postulate chitosan and chitosan-derived co-polymers as an excellent precursor option for industrial applications, especially in smart food packaging [77].…”

“…Far more interesting is the antimicrobial mechanism of chitosan, prominently tailored due to the protonation of the amino group under acidic conditions, harboring ionic interactions among the bacterial cell membrane. Thus, orchestrating the hydrolysis of the peptidoglycan layers (at the membrane or cell wall level), resulting in the rupture and subsequent leakage of cytoplasmatic electrolytes and DNA/RNA components, leading to bacteria lysis [77,94]. Therefore, the molecular weight of chitosan directly influences on the antimicrobial action, which could be improved by adding glycerol to increasing the polymeric response [89].…”

The objective of this study was to carry out the extraction and characterization of chitin and chitosan from the exoskeletons of the Farfantepenaeus californiensis species of shrimp, as well as its application in the formulation of polymeric films plasticized with glycerol used in the process of food packaging. The characterization of the extracted polymer was made by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and physicochemical analysis of chitin and chitosan, resulting in a theoretical performance of 29.33% and 16.46%, respectively. In terms of quality, it was determined that the extracted chitosan had a molecular weight of 1.10 x105 g/mol and a deacetylation degree of 80.23%, which classifies it as a low-molecular weight chitosan, suitable for food packaging. It was shown that the extracted chitosan is fit for the production of the films by using the casting method, presenting a tension resistance of 1 MPa. The Antibacterial analysis was carried out using Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), bacterial models commonly found in food. The results showed an effective inhibition capability of the polymeric materials. Overall, the results for both chitosan and the films indicate a high potential for application in the food packaging sector.

Chitosan Based Biodegradable Composite for Antibacterial Food Packaging Application

et al. 2023

A recent focus on the development of biobased polymer packaging films has come about in response to the environmental hazards caused by petroleum-based, nonbiodegradable packaging materials. Among biopolymers, chitosan is one of the most popular due to its biocompatibility, biodegradability, antibacterial properties, and ease of use. Due to its ability to inhibit gram-negative and gram-positive bacteria, yeast, and foodborne filamentous fungi, chitosan is a suitable biopolymer for developing food packaging. However, more than the chitosan is required for active packaging. In this review, we summarize chitosan composites which show active packaging and improves food storage condition and extends its shelf life. Active compounds such as essential oils and phenolic compounds with chitosan are reviewed. Moreover, composites with polysaccharides and various nanoparticles are also summarized. This review provides valuable information for selecting a composite that enhances shelf life and other functional qualities when embedding chitosan. Furthermore, this report will provide directions for the development of novel biodegradable food packaging materials.

“…Chitosan, suitably functionalized, can be used to create film for food preservation by overlaying the surface of the food product with the biopolymer solution. This coating, with its excellent characteristics, can be applied through different methods 22 , 23 . The easiest and most economical way to prepare chitosan coating is by its solubilization in a slightly acidic aqueous solution.…”

Chitosan was produced from Hermetia illucens pupal exuviae by heterogeneous and homogeneous deacetylation. Tomato fruits (Solanum lycopersicum), that are one of the most grown and consumed food throughout the world, were coated with 0.5 and 1% chitosan, applied by dipping or spraying, and stored at room temperature or 4 °C, for a storage period of 30 days. Statistical analysis give different results depending on the analysed parameters: heterogeneous chitosan, indeed, had a better effect than the homogenous one in maintaining more stable physico-chemical parameters, while the homogenous chitosan improved the total phenols, flavonoids and antioxidant activity. Chitosan coatings applied by spraying were more effective in all the analyses. Chitosan derived from H. illucens always performed similarly to the commercial chitosan. However, a general better performance of insect-derived chitosan on the concentration of phenolics and flavonoids, and the antioxidant activity was observed as compared to the commercial one. Chitosan coating has already been successfully used for preservation of fresh fruits, as alternative to synthetic polymers, but this is the first investigation of chitosan produced from an insect for this application. These preliminary results are encouraging regarding the validation of the insect H. illucens as a source of chitosan.
