Objective: The objective of this study was to monitor the life cycle a new active packaging (AP) based on polyvinyl alcohol (PVA) and clove essential oil (CO), in proportion 15% w/w, be applied storage sliced bread. In cycle, produced materials will characterized, applied, biodegraded by fungus Penicillium expansum, whose enzymes quantified as value-added bioproduct for industry. Theoretical Framework: Active are systems that promote extension shelf products through their interactions with food. Among functions AP, antimicrobial characteristics fundamental food preservation can achieved constituents, such oils, which natural non-toxic compounds. However, beyond merely developing it is necessary evaluate environmentally friendly ways dispose these post-consumer materials. possibilities biodegradation polymeric residues microorganisms liquid medium. Method: Pure PVA films CO were using casting method, employing water solvent. Subsequently, characterized various analyses AP bread during 7 14 days storage. After periods, microbial growth packaged colony-forming units (CFU). To quantify CFU, dissolved 0.1% peptone at 0, 7, days, 0.1 mL distributed onto Petri dishes containing solidified Sabouraud application materials, expansum an disposal method modified media (without glucose). Finally, lipase enzymatic activity evaluated industrial use. Results Discussion: characterization developed demonstrated does not significantly alter properties polymer. addition, observed PVA+15%CO presented better control after compared pure PVA. storage, contained without showed 13,100 CFU·mL⁻¹, while no colonies. Additionally, 25,400 300 respectively. This demonstrates efficiency additive incorporated into matrix. sense, assessed extracts obtained activity, has potential used processes. Originality/Value: Thus, work highlights environmental importance monitoring useful from production disposal, addressing only functional performance but also generating bioproducts. By proposing integrated approach combines sustainability, innovation, responsibility, contributes advancing development eco-friendly solutions align principles circular economy.
