Abstract
Soy protein isolate (SPI) is one of the base materials for edible film production in addition to
polysaccharide and lipid, but it does not have antibacterial activities. Incorporation of antibacterial agents
may increase the functional properties of the edible films. This research aimed to determine the effects of
zinc oxide nanoparticles (ZnO-NPs) and turmeric extract addition into soy protein isolate-based films on
the physical, mechanical and antibacterial characteristics of the films. The edible films were prepared by
dissolving 5 grams of SPI into 100 mL of distilled water followed by the addition of ZnO-NPs (0, 1, and
2.5% of the SPI weight) and/or turmeric extracts (0 and 2.5% of the SPI weight). The results showed that
addition of ZnO-NPs and turmeric extracts into the films significantly increased the thickness and values of
tensile strength. Addition of turmeric extract decreased the percent of films elongation, while addition of
ZnO-NPs had a significant effect in decreasing the water vapor transmission rate (WVTR) values. The
combination of ZnO-NPs and turmeric extracst had a considerable effects in inhibiting E.coli growth in the
range of 2.25 mm to 3.18 mm. Meanwhile, addition of ZnO-NPs resulted in inhibition against E.coli in the
range of 2.54 mm to 4.29 mm. Furthermore, this research showed that addition of ZnO NPs and turmeric
extracts could improve the physical and mechanical properties of SPI-based film. The best films was
obtained by using ZnO NPs at 2.5% which can potentially be used as an antibacterial packaging.
