Development and characterization of biodegradable films from fermented yam (Dioscorea trifida L. f.)

The objective of this work was to develop and characterize biodegradable starch films at 14 and 21 days of fermentation, aiming to develop packaging with added value. For the extraction of starch, yam tubers were washed, crushed, filtered and fermented for 14 and 21 days, and then filtered and dehydrated. Water-starch-glycerol mixtures were prepared in a randomized design using a factorial scheme (5x2), with five...
