The present research was conducted to extract starch from macáçar bean, chitosan from shrimp shells and evaluate the characteristics of the produced blends by different combinations of these raw materials. To obtain the films we used starch from macáçar bean (3g/100 g of film-forming solution) and different percentages of chitosan and glycerol (0/20, 0/30, 5/20, 5/30, 10/20 e 10/30), based-amount of starch (m/m), respectively. Solutions were spilled in Petri’s glass-plates (10 mL) and dried at 40oC, by 24 h. The polymeric matrix, macáçar bean starch-chitosan-glycerol, presented excellent intermolecular interaction to obtain films with good uniformity, continuity, handling and transparency (74,1562 ± 4,8330%). The films obtained are suitable for transparent packaging of dehydrated products and with low moisture content, which require more attractive for commercialization.Downloads
