Influence of Ulluco Starch Modified by Annealing on the Physicochemical Properties of Biodegradable Films.

This work aimed to evaluate the use of annealing (ANN) ulluco starch in the preparation of biodegradable films and its impact on the physicochemical properties of the materials. Three film samples (FS1, FS2, and FS3) were prepared at a fixed starch concentration (2.6% /) using glycerol as a plasticizer and then compared to a control sample (FSC) prepared with native ulluco starch.
