Conteúdo: 	Nanocompositefilms prepared from starch (ST) in the presence of cellulose nanocrystals (CNCs) was performedusing grape pomace asraw material.CNCswere obtainedbyacidhydrolysis and added tofilmogenic solutions (1,2, 5, 10 and 15 g/100 g of ST). Cellulose, CNCs and Nanocomposites were characterized. Amorphous non-cellulosic materials were removed from the grape pomace presented values for CrI 64% and 71% and yield 12and 70% in Cellulose and CNCs, respectively. Nanocomposites showed smaller permeability and the addition of5 to 15% CNCs formed more opaquefilms and had improved tensile strength and Young’s modulus. The additionof CNCs from 5 to 15% proved to be effective in improving mechanicalproperties and decreasing water vaporper-meability, important characteristics in food packaging materials. This study provided an effective method to ob-tain CNCs from the agroindustrial waste and open the way to produce high-value starch based nanocomposites.
