چکیده
Properties of fish skin gelatin films incorporated with three essential oils from various sources (basil, plai and lemon) with a gelatin/essential oil ratio of 1:1 (w/w) were determined. Films containing different essential oils had lower tensile strength and elastic modulus, but higher elongation at break and thickness, compared with the control film (without essential oils) (p < 0.05). Lower water vapour permeability was observed when essential oils were incorporated, in comparison with the control, particularly when basil and lemon essential oils were used (p < 0.05). Films with essential oils had varying L*-, a*-, b*- and ∆E*-values (total colour difference) and WI (whiteness). Amongst all films, that incorporated with plai essential oil showed the highest b*- and ∆E*-values but lowest WI (p < 0.05). Lower light transmittance and higher transparency value, indicating more opaqueness, were observed when films were incorporated with essential oils (p < 0.05), especially for film added with lemon essential oil. Film containing basil essential oil showed the highest DPPH and ABTS radical scavenging activities (p < 0.05), whilst those incorporated with lemon essential oil had the highest chelating activity (p < 0.05). Thus, the incorporation of various essential oils from various sources determined properties and antioxidative activity of fish skin gelatin film differently.
