Abstract
The combination of nanotechnology, biology and biopolymer can be known by the ability to become a smart food coating using anthocyanins in borage plants. These types of materials can be developed in the food industry as a nascent science, and since completely natural and biodegradable polymers are used, these compounds do not harm the environment. Also, anthocyanins with different pHs create a variety of colors, which makes it possible to determine whether the food is healthy or spoiled by changing the color of the film or coating. Also, nanomaterials such as nanochitosan and metal nanoparticles can improve the properties of the made film, especially from the point of view of greater resistance to bacteria and moisture penetration. A highly suitable approach for synthesizing nanomaterials involves the application of eco-friendly and green chemistry resources. These green-synthesized materials have gained attention for numerous applications based on their environmental sustainability and affordability. Green-synthesized nanoparticles (NPs) have been extensively researched for their potential in food packaging. In this study, copper nanoparticles were produced using Thymus kotschyanus. To evaluate the greenness of this method, two softwares, Agree and Agreeprep, were used. According to the results, it can be concluded that this film can be marketed as a smart and completely environmentally friendly coating to improve food health and beneficial for consumers. Making a biodegradable film using chitosan and alginate with antibacterial copper nanoparticles and making it smart with anthocyanins from the Echium amoenum plant resulted in a unique film with satisfactory properties.
