G.  aWater sorption on chitosan filmsbpreliminary study for protective edible coatings on sliced fruits.  c2002  aChitosan films cast from different precursor concentrations solution were investigated as potential edible coatings on fruit. All films were inhomogeneous with intrinsic porosity, featuring a "mountain-and-valley" structure. Gain of mass by water and phosphate buffer sorption were measured, showing a high affinity towards water, dure to the presence of hydrophilic groups in exponentially. Weak adherence was also observed as chitosan content increases in the film.  achitosan  apolysaccharides  aEdible coating  aWater absorption1 aALBERTIN, L.1 aFLORES, A. M.  tIn: MATTOSO, L. H.
