The development of new bio-materials from largely available and cheap residual biomass resources, such as agro-industrial residues, to produce green/edible packaging manufactures is one of the major challenges from scientific and technological viewpoint (1). Mechanical milling was selected in this work for the preparation of novel green/edible composites consisting of tomato peels (TPs) as a bio-based matrix and carvacrol encapsulated into HNTs as a natural antibacterial agent (filler loading: 2.5, 5, 10, 20 wt%) (2). The structural organization and the main physical properties of the obtained active bio-based composites were investigated; in particular, thermal and mechanical properties along with the films' interaction with water vapor were assessed and then correlated to the filler loading. The sustained release of carvacrol was also analyzed.

Abstract
The development of new bio-materials from largely available and cheap residual biomass resources, such as agro-industrial residues, to produce green/edible packaging manufactures is one of the major challenges from scientific and technological viewpoint (1). Mechanical milling was selected in this work for the preparation of novel green/edible composites consisting of tomato peels (TPs) as a bio-based matrix and carvacrol encapsulated into HNTs as a natural antibacterial agent (filler loading: 2.5, 5, 10, 20 wt%) (2). The structural organization and the main physical properties of the obtained active bio-based composites were investigated; in particular, thermal and mechanical properties along with the films' interaction with water vapor were assessed and then correlated to the filler loading. The sustained release of carvacrol was also analyzed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
