Resumen:
Public concern about environmental pollution have stimulate the interest in developing products from renewable resources, economically competitive and with minor environmental impact.1 In particular, chitosan, the de-N-acetylated form of chitin, is a natural cationic polysaccharide, non-toxic, biodegradable and available commercially, that has been employed in a variety of applications.2 It is a well-known biopolymer that acts as stabilizer of hydrocolloids - lipids mixtures, promoting emulsion formation and interfacial stabilization. On the other hand, CNC (cellulose nanocrystals) have attracted significant attention because they are renewable and environmentally benign, naturally abundant, biodegradable, biocompatible and have excellent mechanical properties. The objective of this work is to improve the resistance to water of chitosan films by the addition of hydrophobic compounds such as olive oil and at the same time, to improve the mechanical response by the incorporation of cellulose nanofibers.
