Abstract

Abstract - Vegetable oil packaging materials use a type of synthetic polymer that is harmful to the body and the environment. Edible film as an environmentally friendly packaging material can be a solution for vegetable oil packaging material. Edible films are made from natural ingredients such as starch and chitosan. The objective of this study is to determine the best conditions of addition of chitosan in making edible film in terms of its physio-chemicals and determine the best glycerol concentration in terms of its physical properties. The composition of raw materials in the form of corn starch is 5 grams and the composition of chitosan is (0,5%, 1% and 1,5% b/v). Glycerol concentrations vary in (4%, 5% and 6% v/v). the result of the analysis of the physical properties of the edible film through the analysis of the physical tensile strength test, namely the best composition on the addition of 1 gr chitosan as well as the elongation analysis at termination. Analysis of the solubility of the edible film at a concentration of 1 gr as well the analysis of water vapor permeability. Whereas the analysis of the best antioxidant capacity in the composition of chitosan is 1,5 gr. Keywords: corn starch, chitosan, edible film

Abstract

The papuyu fish (Anabas testudineus) is a freshwater species found in South and Southeast Asia. It is known for its ability to survive in extreme conditions, such as low oxygen levels and poor water quality, making it a potential candi-date for climate-resilient aquaculture. In this study, chitosan was extracted from the scales of papuyu fish through de-mineralization using 1 N HCl solution, deproteination using 5% NaOH solution, and deacetylation using 70% NaOH solution, resulting in an overall yield of 5.11%. The extracted chitosan was added to edible film made from corn starch, and the properties of the prepared films were characterized via Fourier transform infrared spectroscopy, scanning elec-tron microscopy, water solubility test, and water vapor permeability test. Fourier transform infrared spectroscopy re-vealed the presence of characteristic peaks of chitosan, such as amide I (C=O) and amide II (C–N), at around 1647.26 cm−1. Scanning electron microscopy revealed the presence of pores in the edible films. Furthermore, the water solubility of the prepared films decreased with increasing chitosan content. However, the addition of chitosan did not significant-ly affect the permeability
