Abstract
A study was carried out to evolve a biodegradable packaging material with
combinations of chitosan and turmeric essential oil at various concentrations (0%,
0.25%, 0.5%, 0.75% and 1%). A significant (P<0.05) decrease in water vapor
permeability, water solubility and swelling degree were observed in chitosan film
with 0.75% and 1% TEO whereas thickness and transparency significantly (P<0.05)
increased. Tensile strength and elongation at break were found to be significantly
(P<0.05) decreased when TEO concentration increased. A significant (P<0.05)
increase in redness (a*) and yellowness (b*) of film was observed when TEO
concentration increased. Chitosan film with 0.75% and 1% TEO showed significant
(P<0.05) increase in DPPH radical scavenging activity.
