Abstract

This study aimed to evaluate the influence of incorporating two concentrations of microcapsules containing Pulicaria jaubertii extract (MPJE) on the physicochemical, microstructure, and bioactivities properties of films based on chitosan (CH), gelatin (GEL), and CH50:GEL50 for possible use as active food packaging in the future. The MPJE treatment was compatible with the CH and/or GEL film without affecting chemical structures. Physico-mechanical results revealed that the CH50:GEL50 film showed optimal properties. The films blended with MPJE considerably improved in glass transition temperature and thermal stability. The films treated with MPJE presented high barrier property toward UV and visible light. Compared with that of the control films, the microstructure of the films loaded with MPJE had a rougher surface with homogeneous microcapsules, which increased with increasing MPJE concentration. Furthermore, mixing MPJE with CH and/or GEL led to the for�mation of high bioactive films with lower moisture content than the control films, suggesting that MPJE can be utilized to preserve lipid-rich foods.
