Abstract
In this work, date-fruit syrup waste extract (DSWE) was used as an antioxidant additive to develop active gelatin films with enhanced food preservation properties. The effect of DSWE content (5, 10, 15, and 25 wt%) on the mechanical, physical, and antioxidant properties of the gelatin films were analyzed. Total phenolic content and antioxidant assay analysis revealed that the active compounds in blend films are highly migrated to the aqueous phase than the fatty medium. In the canola oil stability studies, gelatin/25 wt% DSWE film immersed oil sample exhibited low peroxide (POV) and p-anisidine (PV) values of 28.6 and 7.1, respectively, compared to the control oil (POV = 41.7 and PV = 13.1) in the air atmosphere and 45 °C for 30 days. Totox values of canola oil samples were decreased as a function of DSWE content in the films, indicating that polyphenols in DSWE are significantly resistant to oil's lipid oxidation.
