Abstract
The use of conventional plastics represents a major environmental problem, as approximately 79% ultimately accumulates in landfills or natural ecosystems. As a result, there is growing interest in the development and application of renewable materials for food packaging. In addition, there is an increasing concern regarding the consumption of high-quality and safe foods. To address this issue, active packaging has emerged as a key strategy to extend food shelf life, since unrenewable often fails to prevent deterioration caused by microbial activity or oxidation. Therefore, the aim of this study was to obtain and evaluate active biofilms based on hydroxypropyl methylcellulose (HPMC) incorporated with Moringa oleifera extract, through enzymatic inactivation analysis in a food matrix. The films were prepared using the casting method. The results showed that the extract exhibited a high concentration of phenolic compounds and remarkable antioxidant capacity. The developed films demonstrated the ability to affect enzymatic activity in Hass avocado (Persea americana), promoting greater enzymatic inactivation during storage and contributing to the delay of oxidative processes associated with deterioration. In this context, the results indicate that Moringa oleifera extract enhances the performance of HPMC as an active material, positioning these biocomposites as a sustainable alternative for extending the shelf life of food products and reducing environmental i
