Película biodegradable de almidón de maíz termoplástico y quitosano con actividad antimicrobiana empleada como envase activo

ABSTRACT One of the research lines related to active packaging takes into account the incorporation of antimicrobial agents such as chitosan, a polysaccharide derived from the crustaceans’ exoskeleton. However, because of chitosan high molar mass, its diffusion from the package to the food surface is restricted, so the use of oligomers is an interesting but less investigated alternative. The purpose of this work was to obtain active films based on thermoplastic corn starch (TPS) by adding oligochitosans (OC, molar mass = 290 g mol-1 and degree of polimerization = 2). Films were thermo-compre...
