Controlled Release of Quercus infectoria Extract from Jackfruit Starch-Konjac Glucomannan Film

Article Preview

Abstract:

Jackfruit (JS)-konjac glucomannan (KGM) blend films were prepared using different concentrations of JS, KGM and glycerol. Their mechanical properties were determined. All the films exhibited significantly higher values of tensile strength and elongation at break than those of neat JS films. The values varied considerably depending on KGM and glycerol content. Quercus infectoria extract was embedded into the films and its release characteristics were controlled by changing the initial KGM content. This study suggests that the blend film has a potential use for advanced controlled release of bioactive extracts.
