Title A name given to the resource A Comparative Study of Nutrient Composition, Proteolytic Activity, Phytochemical Profiles, Vitamin C Content, and Antioxidant Properties in the Peels of Selected Perennial Fruits Subject The topic of the resource Anti-nutritional constituents; Fruit peels; Nutritional analysis; Phytochemical analysis; Ripening stage Description An account of the resource The escalating global demand for fruits has led to a surge in fruit production, resulting in significant fruit waste, particularly peels. The present study aims to investigate the nutrient content, proteolytic activity, phytochemical levels, vitamin C and antioxidant properties of five perennial fruits, namely Carica papaya (papaya), Selenicereus costaricensis (Red dragon fruit), Ananas comosus (Pineapple), Musa acuminata (Cavendish banana), Punica granatum (Pomegranate) peels of varying ripening stages. Accordingly, two ripening stages for pomegranate, papaya and dragon fruit (PoR1 and PoR2; PaR1 and PaR2; DR1 and DR2, respectively) and three stages for banana and pineapple (BR1, BR2 and BR3; PiR1, PiR2 and PiR3, respectively) were identified based on ethylene gas emission. The elemental analysis showed that fruit peels of Pineapple (PiR3), Banana (BR2), Papaya (PaR2), and Dragon fruit (DR2) showed significantly higher content of macro and micro-elements compared to the other ripening stages. Pomegranate peels exhibited the highest proteolytic activity (5.09 0.98unitsg?1), total phenolics (246.09 0.25mgg?1), total flavonoids (158.27 1.72mgg?1), tannins (103.94 0.09mgg?1), DPPH scavenging activity (129.43 1.34%), and antioxidant activity (127.14 1.35mgg?1 by phosphomolybdate assay). A. comosus peels had the greatest vitamin C levels (95.53 3.52mgg?1). Anti-nutrient analysis revealed safe levels of oxalates, phytates, and alkaloids, except for high oxalate levels in pomegranate peels. Notably, all parameters exhibited an increasing trend with ripening stages, with a decline during senescence in Banana (BR3) and Pomegranate peel (PoR2). This knowledge of fruit peel composition can enhance their utilization by humans, pharmaceutical and food industries, while also contributing to more effective waste management. Our study addresses the pressing need for sustainable fruit peel utilization in the context of escalating fruit production and waste.
