Abstract
|
|
|
|
Tuna skin byproduct extract (TSB) was used as a biocompatibility film base material, and its composite film with gellan gum (GG) was prepared. In addition, Pinus thunbergii cone extract (PTCE) was incorporated into the film to provide anti-oxidant and anti-bacteria activities. The tensile strength (TS) of the TSB/GG composite films increased with increasing GG content, whereas elongation at break (E) decreased. TSB/GG film at a ratio of 0.5:0.5 (w/w) showed the most desirable TS and E values. Based on scavenging free radical potentials and disc diffusion method results against growth of bacteria, antioxidant and anti-bacteria activities of films increased with increasing PTCE concentration. Accordingly, this study showed that TSB/GG could be used as a film material while the TSB/GG composite film containing PTCE can be utilized as functional packaging.
