Abstract
The present work aimed to develop a new antibacterial composite edible film of whey protein-based containing peanut oil (PO). Different concentrations of PO (0, 2, and 4% wt.), glycerol (Gly) (10, 15, and 20% wt.), and Tween 80 (2% wt.) were used as ingredients. The used of PO as antibacterial compound in the edible film was applied on fresh chicken meat during storage time at room temperature (25°C) and refrigerated temperature (-5°C) for 10 d. The characteristics of edible film, texture, and TPC on chicken meat were evaluated. Based on the results, the incorporation of Gly to the film increased the moisture content, while the incorporation of PO to the film decreased the moisture content, and slightly increased the thickness. The antibacterial effect of the composite film increased linearly with increasing PO concentration. The shelf life of chicken meat for film containing 4% wt. PO was the best during chilled temperature storage for 10 d.
