In recent years, there has been growing interest in the reuse of fruit and vegetable processing of by-products due to their valuable components. This paper presents both conventional and innovative extraction methods that enable the recovery of many desirable bioactive compounds. In addition to their potential application in enriching soil with minerals and supplementing animal feed with dietary fiber, these compounds can primarily be used to enhance traditional food products by imparting health-promoting properties. Overall, the utilization of by-products generated in the fruit and vegetable sector offers numerous economic, environmental, and social benefits for the agri-food industry. These practices are in line with the principles of sustainable development and efficient resource management.
