The aim of this work was to develop antioxidant films based on blends of Stenochlaena palustris flour and poly(vinyl alcohol) (PVA). Four different PVA types were tested. All films produced were analyzed for their antioxidant activity by diphenylpicrylhydrazyl radical scavenging (DPPH) method. S. palustris flour – PVA 88% blends film contains the highest antioxidant activity. The kinetic study of the selected film shows the antioxidant amount to decrease the radical concentration by 50% (EC50), time to reach a steady state at the concentration corresponding to EC50 (TEC50) and Antioxidant Efficiency value of 20 mg/ml, 55 min and 0.91×10-3 respectively. The use of low concentration PVA and addition of glycerol made the film more flexible with greater elongation at break but low tensile strength. The thermogravimetric analysis shows the thermal degradation of the film produced. 2011-07-08T03:50:00Z 2011-07-08T03:50:00Z 2010-05 Learning Object http://hdl.handle.net/123456789/13105 en Universiti Malaysia Perlis School of Bioprocess Engineering
