Capitalize on a hidden resource with this essential book, offering a comprehensive guide to fruit waste valorization and cutting-edge techniques for extracting high-value bioactive compounds for the food and pharmaceutical industries. The fruit production and processing sectors produce tremendous amounts of waste that cause significant economic losses and an undesirable impact on the environment. The effective utilization of these fruit wastes can help reduce the world’s carbon footprint and greenhouse gas emissions to achieve sustainable development goals. These by-products contain a variety of bioactive compounds, such as dietary fiber, flavonoids, phenolic compounds, antioxidants, polysaccharides, and several other health-promoting nutrients and phytochemicals. These bioactive compounds can be extracted and used as value-added products in different industrial applications. The bioactive components extracted can be used in developing nutraceutical products, functional foods, or food additives. This book provides a comprehensive review of the recent developments in fruit waste valorization techniques and their applications in the food, feed, and pharmaceutical industries. It explores various extraction techniques, including conventional and emerging methods, the antioxidant and antimicrobial activities of the active compounds extracted and isolated from fruit waste, food industrial applications of bioactive compounds extracted from fruit waste, and lifecycle analysis, challenges, and the entrepreneurial developments of fruit waste bioprocessing, making it an essential resource for researchers and industrialists alike.
