DEVELOPMENT AND CHARACTERIZATION OF BIODEGRADABLE FILMS OBTAINED FROM BOCAIUVA FLOUR (Acrocomia aculeata)

Favorite this paper

The aim of this work was to develop and characterize biodegradable films obtained from different concentrations of bocaiuva (Acrocomia aculeata) flour, clove essential oil and glycerol as plasticizing agents. The characteristics of the films were evaluated by visual and tactile aspects, staining and absence of bubbles and insoluble and flexible particles, ease of handling, thickness, traction and elongation. The results showed that, regardless of the concentrations used in the treatments, all the films were symmetrical. However, as the flour concentration increases, films show a decrease in tensile strength and elongation. These results indicated that the amount of solution is determinant to enable the formation of films.
