Phenolic Profiling of Berries Waste and Determination of Their Antioxidant Potential

This study evaluated the phenolic content and antioxidant potential of waste from four types of berries: blueberries, blackberries, raspberries, and strawberries, in Australia. Blueberry waste was found to have the highest phenolic content and antioxidant potential, with specific measurements provided for total phenolic, flavonoid, and tannin content, as well as antioxidant capacity. The analysis identified 87 compounds across the berry wastes, with blueberries showing higher levels of specific phenolic acids and flavonoids. The findings suggested that phenolics from berry wastes could be repurposed in various industries, including food, feed, pharmaceutical, and nutraceutical sectors.
