摘要：

The objective of this research was to determine the effect of Uncaria gambir Roxb filtrate addition on functional edible films based on corn starch. This study used a Factorial Randomized Completely Design with two treatments and three replication for each treatment. The first factor was the concentration of Uncaria gambir Roxb filtrate (20%, 30%, 40%) and the second factor was the mixing separation method (filtering, centrifuge 1000 rpm, centrifuge 2000 rpm). The results showed that treatment of Uncaria gambir Roxb filtrate and the mixing separation method had significant effect on thickness, elongation percentage, water vapour transmission rate, antioxidant and antibacterial activities of edible film. The interaction of Uncaria gambir Roxb filtrate and the mixing separation method had significant effect on water vapour transmission rate. The best treatment based on edible film characteristics was 40% concentration of Uncaria gambir Roxb filtrate and the mixed separation method of 1000 rpm centrifugation.
