eng	Characterization of biocidal polylactide (PLA) films for active food packaging	Microbial food spoilage is a significant issue that leads to substantial economic losses. Effective preservation methods are essential to reduce food waste. However, increasing consumer concerns about the safety and health impact of conventional preservatives drive the search for new, preferably natural, antimicrobial compounds. Plant-derived phenolic compounds are promising candidates for use in active packaging. These compounds can be incorporated into packaging materials either as sachets or directly into polymers. The study aimed to develop an active food packaging material based on polylactic acid (PLA) containing cinnamaldehyde and carvacrol, selected based on their minimum inhibitory concentration (MIC) values against foodborne pathogens. The films were evaluated for biocidal activity according to ISO 22196:2011(E), biodegradability using the OxiTop® system, and antioxidant properties. Additionally, the impact of the materials on soil health was assessed by analyzing their effect on enzyme production by native soil microorganisms. The prepared materials demonstrated significant biocidal activity against foodborne pathogens, maintained biodegradability, and had no adverse effects on soil health. These findings suggest that the developed materials could be suitable for extending food freshness. However, further studies are necessary, including the evaluation of their impact on the sensory properties of food.	PLA; food packing; biodegradability; MIC
