description This study addresses challenges faced by the packaging industry in finding suitable natural and biodegradable materials that can replace plastics while preserving the superior quality and freshness of the items contained within. Chitosan, a biodegradable natural polymer, shows great potential as a matrix for ecofriendly and biodegradable composite materials. In the present study, bioactive substances such as caffeine (CAF) and propolis extract (EP) were used for the enhancement of the bioactivity of chitosan-based films. Two acidic solvents, acetic acid and citric acid, were used to produce chitosan films. The study examined the antioxidant capabilities of the solutions used for film formation; similarly, the characteristics of the resultant films were also examined, encompassing antimicrobial, barrier, and mechanical characteristics. The findings suggested that the use of additives exhibiting antioxidant activity, such as CAF and EP in the chitosan matrix can be an effective method to counteract oxidative stress in food packaging. The study also showed that films produced with citric acid exhibit antimicrobial activity against many strains of bacteria, including foodborne pathogens. In addition, the antimicrobial activity of chitosan/citric acid film can be increased by adding CAF and EP. The results confirmed that both the additives and the acids used affect the mechanical and barrier features of the obtained chitosan-based films. This study suggests that chitosan films supplemented with natural bioactive substances have the potential to serve as viable replacements for traditional plastics in the packaging sector.
