Different natural biopolymers are becoming the issue of an expanding number of studies reporting their potential applications in food, pharmaceutical and cosmetic technologies, as well as in tissues engineering [1-4]. In this respect, the utilization of charged polysaccharides like chitosan (CH) or pectin (PEC) appears to be one of the most interesting way in manufacturing of biodegradable new materials [4]. CH is a cationic biopolymer under pH 6.0 and derives from the N-deacetylation of chitin, the natural polysaccharide responsible for the hardness of the crustacean shells [5]. CH is a copolymer consisting of β-(1–4)-2-acetamido-D-glucose and β-(1–4)-2-amino-D-glucose units with the latter usually exceeding 60%. Due to its non toxic, biodegradable and biocompatible properties, CH is extensively used in the biomedical area as wound healing material and for sustained release of drugs [6] …
