The aim of this study is to increase the shelf life and quality of strawberries, using a composite coating of concentrated milk protein-pectin reinforced with calcium chloride and Nigella sativa L. essential oil during 10 days of storage at 4±1°C. The effect of edible coating based on condensed milk protein (4, 6 and 8%), pectin (0, 2 and 4%), calcium chloride (1, 2 and 3%), glycerol (2, 3 and 4%) and Nigella sativa L. essential oil (2%) is investigated. After optimizing the microbial quality of coated strawberries, their physicochemical properties, antioxidant activity, anthocyanin content, and tissue hardness were compared with the control samples at 5 and 10 days after storage. All the studied qualitative characteristics of the coated samples were significantly different from the control samples (p <0.05). The results showed that this edible coating maintains the quality of strawberries in comparison to the uncoated control samples due to rot reduction.
