Abstract

Despite being historically relegated as a by-product, orange peel (OP) has gained prominence as a source of beneficial phytochemicals, such as flavonoids, phenolic acids, carotenoids, and limonoids. These compounds collectively confer potent free radical scavenging capabilities, offering robust protection against oxidative stress-induced cellular damage. For instance, OP has been considered a tale of cultural significance for its outstanding properties. Besides, contains a great variety of antioxidants and nutrients that contribute to its health-promoting benefits. The present study addresses various methodologies employed in the evaluation of antioxidant capability, while also addressing the factors influencing bioavailability and absorption. Additionally, we underscore the diverse health implications associated with the consumption of OP-derived antioxidants, encompassing their potential to mitigate oxidative stress-related disorders. Moreover, this work presents methods for assessing antioxidant capacity in OP. Specifically, this review brings together several essential aspects of OP from health perspective. This mainly includes the consumption of OP, encompassing cardiovascular and dermatological well-being, bolstering the immune system, protecting neurological functions, potentially contributing to the prevention of cancer and maintenance of gastrointestinal health. Finally, this work presents practical dietary suggestions for integrating antioxidants from OP, with due attention to safety considerations. In a nutshell the study highlights the potential incorporation of antioxidants derived from OPs into contemporary healthcare and dietary approaches to promote improved overall health.
