Resumen

Starch extracted from breadfruit cultivated in Ecuador was proposed as the main input to develop edible films. Starch was first extracted by the humid technique and then was modified by such techniques as pre-gelatinization (physical) and cross-linking (chemical). Starch yield was 44.44 %, on dry basis. 4 treatments (T1, T2, T3, and T4) were established according to concentrations of modified starch and glycerin. Edible coatings were obtained by casting. Physical and mechanical properties assessed were moisture (%), solubility (%), opacity (mm-1), thickness (mm), and tensile strength (MPa). T2 presented the best physical and mechanical properties with the exception of the opacity, which presented any detectable values. The modified starch extracted from this vegetable may be suitable for the development of edible coating as far as the concentrations of starch and glycerin may be controlled during the manufacturing process
