Valorizing sugar‐rich food waste in biorefineries offers a sustainable route to bio‐based products. Grapefruit peel (GP), representing about 50% of the fruit's weight, is rich in sugars (soluble and insoluble) and polyphenols such as flavonoids. The present study investigates an integrated green extraction strategy using high‐intensity focused ultrasound (HIFU) and enzymatic hydrolysis (EH) to recover phenolic compounds and sugars from GP.
