The antimicrobial, mechanical and barrier properties and light transmission of sago starch film incorpo-rated with different percentage of Betel leaf extract (5%, 10%, 20%, and 30%)
were evaluated. With regardto mechanical properties, tensile strength decreased when the percentage of extract increased.
Elonga-tion at break (%) and seal strength (N/m) increased with increasing percentage of extract from 5% to 20%
,while decreased for films containing 30% extract due to heterogeneity of films in this percentage
With regard to barrier properties,
water vapour and oxygen barrier properties decreased in all samples whenpercentage of the extract increased.
Antimicrobial activity of all the films increased against both Grampositive and Gram negative bacteria as percentage of Betel leaf extract increased,
except for Psuedomonasaeruginosa, which was not susceptible at any percentage of the extract.© 2014
