Abstract

Starch-based edible films are gaining high interest in the food packaging industry. In this study, to assess the usefulness of the waste, avocado seeds were extracted to obtained the starch and used to developed edible films. The usage of carnauba wax was known to improved the mechanical characteristics of starch- based edible films. The aimed of this study was to determined the interaction and the characteristics of edible film from avocado seed starch and carnauba wax. This study used a Randomized Block Design (RBD) factorial consist of two factors. The first factor was the difference in the concentration of the avocado seed starch consisting of 3 levels (2%, 3% and 4%) and the second factor was the addition of carnauba wax (0.3%, 0.6%, and 0.9%) with 3 replications. Physical and mechanical properties of the edible film were analyzed, i.e: thickness, transparency, percent of solubility, tensile strength, elongation, and water vapor transmission rate (WVTR). The data was analyzed with Analysis of Variance (ANOVA) with significance 5% and continued with the Duncan Multiple Range Test (DMRT). The results showed that there was an interaction between the addition of avocado seed starch and carnauba wax on thickness and transparency. The concentration on each addition of avocado seed starch and carnauba wax has a significant effect on the parameters on thickness, transparency, solubility, and water vapor transmission rate (WVTR). The results showed the physical characteristics of edible film on the use of avocado seed starch (2%, 3%, 4,%) and carnauba wax (0,3%, 0,6%, 0,9%) was obtained on thickness 0.13–0.21 mm, transparency 3.576A546/mm–5.292 A546/mm, solubility 32.10–48.99%, percent of elongation 14.00–16.80%, tensile strength 0.43–0.66 MPa, and water vapor transmission rate (WVTR) 4.39–5.90 g/m2/day.
