Biopolymers extracted from agricultural starchy commodities can be raw materials for edible, biologically degradable plastics. They have promising uses, having been proposed for replacing synthetic films. There are several starchy sources not yet quite exploited such as tropical roots and tubers that could be excellent starch sources to produce edible films with distinctive functional properties. The objective of this study was to formulate edible films ITom six tropical root and tubers starches. Starches were extracted and purified to 97-99% purity ITom Ipomoea batatas, andArracacia xanthorriza roots, Colocasia esculenla and Xanthosoma sagi/lifolium corms and Dioscorea Irifida tubers (white and purple) cultivated in the Venezuelan Amazons. The non-conventional stilrches were characterized for purity, amylose content and gelatinization profile by OSC, starch granular morphometry, and rheological properties. Film forming suspensions were formulated to produce the edible films using starch (2.5 ahd 5.00 g /100 g of solution) and glycerol (1.50 and 2.5 g/100 g of solution). Starch suspensions were gelatinized by heat, degassed, poured in plates and dried. In the films, the following studies were performed: Mechanical properties, thickness, and water vapor, oxygen and COl permeability. Films were very good barriers to gases, had high water permeability and the botanical origin may affect the properties of the films. Nonconventional sources can be used for film preparation with barrier and mechanical characteristics that can be tailored for specific uses in the food industry. Next studies to conduct on films are Scanning Electron MicroscQPY, X-ray diffraction, and other supramolecular tests.
