“…The test was performed using an electronic universal material testing machine (Bluehill3, INSTRON), and the modified starch film was stretched at a speed of 30 mm/min in order to cause breakage. Mechanical properties, stress–strain curves, tensile strength, and elongation at break were tested ( Kahya et al, 2022 )with six parallel settings for each sample of modified starch film.…”

“…Recently, Kahya et al [ 92 ] conducted a study about the incorporation of aqueous extracts from sage and rosemary in chitosan films as a potential food coating with antioxidant properties. The films supplemented with the extracts showed a significant increase in the ability to reduce DPPH radicals (ranging from 10.53% to 84.46%), and FRAP values varied from 3.78 to 25.76 FeSO4.7H 2 O μmol eq/g dry film.…”

Chitosan is the deacetylated form of chitin regarded as one of the most abundant polymers and due to its properties, both chitosan alone or in combination with bioactive substances for the production of biodegradable films and coatings is gaining attention in terms of applications in the food industry. To enhance the antimicrobial and antioxidant properties of chitosan, a vast variety of plant extracts have been incorporated to meet consumer demands for more environmentally friendly and synthetic preservative-free foods. This review provides knowledge about the antioxidant and antibacterial properties of chitosan films and coatings enriched with natural extracts as well as their applications in various food products and the effects they had on them. In a nutshell, it has been demonstrated that chitosan can act as a coating or packaging material with excellent antimicrobial and antioxidant properties in addition to its biodegradability, biocompatibility, and non-toxicity. However, further research should be carried out to widen the applications of bioactive chitosan coatings to more foods and industries as well was their industrial scale-up, thus helping to minimize the use of plastic materials.

“…The plant extracts contain phenolic compounds, which are responsible for their antibacterial properties. These properties are related to the presence of a hydroxyl group in phenolic compounds [ 99 , 100 ] and can be used to improve the antibacterial properties of chitosan films [ 101 , 102 , 103 , 104 ]. The hydroxyl group disrupts the activity of the microbial cell membrane–it causes its disruption and leakage of cell components [ 92 ].…”

“…By inhibiting the growth of pathogenic and rotting microorganisms, it is possible to extend the shelf life of packaged food products. Plant extracts, among others, can be used as natural antimicrobial additives from barberry, saffron, garlic, red cabbage, mango leaf, pomegranate rind, or essential oils such as those obtained from cloves, oregano, thyme, or rosemary [ 101 , 162 , 163 , 164 , 165 , 166 ]. Antimicrobials can be incorporated inside the biopolymer matrix or as a coating on their surface [ 163 ].…”

Recently, the development of materials based on natural polymers have been observed. This is the result of increasing environmental degradation, as well as increased awareness and consumer expectations. Many industries, especially the packaging industry, face challenges resulting from legal regulations. Chitin is the most common biopolymer right after cellulose and is used to produce chitosan. Due to the properties of chitosan, such as non-toxicity, biocompatibility, as well as antimicrobial properties, chitosan-based materials are used in many industries. Many studies have been conducted to determine the suitability of chitosan materials as food packaging, and their advantages and limitations have been identified. Thanks to the possibility of modifying the chitosan matrix by using natural additives, it is possible to strengthen the antioxidant and antimicrobial activity of chitosan films, which means that, in the near future, chitosan-based materials will be a more environmentally friendly alternative to the plastic packaging used so far. The article presents literature data on the most commonly used natural additives, such as essential oils, plant extracts, or polysaccharides, and their effects on antimicrobial, antioxidant, mechanical, barrier, and optical properties. The application of chitosan as a natural biopolymer in food packaging extends the shelf-life of various food products while simultaneously reducing the use of synthetic plastics, which in turn will have a positive impact on the natural environment. However, further research on chitosan and its combinations with various materials is still needed to extent the application of chitosan in food packaging and bring its application to industrial levels.
