Abstract
The research objective was to analyse the incorporation effect of gambier filtrate and rosella flower petals extract on mechanical properties and antioxidant activity of canna starch-based active edible film. This research used an experimental method consisting of two treatments, namely gambier filtrate (A): A1 = 3, A2 = 4, and A3 = 5 (% v/v), as well as rosella flower petals extract (B): B1 = 2, B2 = 4 and B3 = 6 (% v/v) and each treatment was replicated three times. The results showed that the two treatment interactions significantly influenced elongation percentage, water vapour transmission rate, and antioxidant activity. The edible film’s thickness, tensile strength, and water vapour transmission rate were 0.096-0.124 mm, 1.89-3.38 MPa, and 12.99-17.04 g.m-2.d-1 , respectively. The edible film contains an antioxidant compound of the strong category with IC50 values of 34.53 to 48.02 ppm. Treatment of A3B2 [gambier filtrate 5% (v/v) and rosella flower petals extract 4% (v)] was the best treatment. This edible film is generally suitable for application as a packaging material for food having high lipid content to inhibit the oxidation process of that food.
