Resumo

Biopolymers appear as a great candidate for plastic substitution in a wide array of industries, attracting interest for its non-toxicity and biodegradability. Among the biopolymers, starch can be highlighted due to its abundance and capability to undergo diverse chemical and physical modifications. Therefore, the aim of this work is to produce films with native and modified cassava starch and analyze its physicochemical properties. Starch was extracted directly from cassava; it was modified by thermal treatment and oxidation and the films were produced by casting. The films presented smooth and homogeneous surfaces. The thermal treatment induced the most significant changes on film characteristics, increasing the elongation at break and the swelling capability. Therefore, the thermal modification of cassava starch resulted in films with enhanced properties, which may find applications from packaging to biomedical devices. (AU)
