The Effect of Lauric Acid Addition on Characteristics of Biocomposite Edible Film

Abstract:

The biocomposites were prepared from chitosan, carragenan and modified tapioca with lauric acid addition. The biocomposite were used as edible film material thus improving the mechanical characteristics. The purpose of this study was to determine the amount of lauric acid addition that produced biocomposites with the best characteristics. This study used experimental method. The different concentration of lauric acid used as the treatment was 0%, 10%, 20%, 30%, 40% from total solid of hydrocolloids materials (w/w). Data were analyzed statistically using the F test (ANOVA test) with confidence level of 95%. The results showed more than 10% addition of lauric acid decreased the value of moisture content, tensile strenght, percent elongation and water vapor transmission but increase thickness, opacity and transparency value. The addition of 10% lauric acid produced biocomposite with the best characteristics according to JIS (Japanese Industrial Standard) which had the moisture content of 42.65%, thickness of 0.047 mm, tensile strength of 13.8 MPa, percent elongation of 29.2%, water vapor transmission rate of 8.5 g/m²/day, opacity 8.9% and transparency 7.5. This research used renewable and biodegradable materials that can be applied to produce edible packaging with the best characteristics and eco-friendly.
