Properties and characterization of biodegradable films obtained from different starch sources

The increasing use of natural biodegradable polymers to preserve foods is a consequence the concern society with sustainability. Starch stands out amongst due its great availability on worldwide scale, high extraction yield and nutritional value, low cost, biodegradability biocompatibility. Apart from traditional sources, various others exist potential. objective this study was identify films different non-traditional starch sources properties revealing their potential be applied as coating for fruits vegetables. were prepared three concentrations (2, 3 3.5%) each following sources: cassava, yam, jackfruit seed mango kernel. starches studied are promising ingredients formulation films, presenting good physical, optical (such transparency) mechanical characteristics, principally tensile strength whose maximum value 36.63 MPa. Increases in concentration directly influenced thickness, water vapor permeability, puncture force. greatest potentials according characteristics 3% 3.5% 2% mango.
