Valorization of Subtropical Fruit Wastes as Sources of Bioactive Compounds
摘要
Using fruit by-products has emerged as a pivotal strategy in addressing sustainability challenges inherent to the food industry’s by-products. This chapter offers a comprehensive review of subtropical fruit residues, including kiwifruit, Citrus fruits, banana, avocado, mango, papaya, pineapple, dragon fruit, and custard apple as a case study, encompassing peels, seeds, pulp, and other inedible parts, with a focus on their nutritional composition and bioactive compound profile. These by-products are recognized as rich sources of nutrients and bioactive compounds, such as polyphenols, pigments, vitamins, minerals, and dietary fibers, which are linked to a variety of health benefits, including antioxidant, anti-inflammatory, anticancer, antidiabetic, neuroprotective, and antimicrobial properties. Additionally, the chapter explores the diverse applications of derived products in promoting health and well-being, spanning functional ingredients in food, supplements, cosmetics, and pharmaceuticals, along with their potential in animal nutrition and soil enrichment. The global distribution patterns of tropical fruit production and their impact on European markets through importation and specific regulations are also discussed. Economic and environmental dimensions of fruit waste utilization are scrutinized, highlighting its pivotal role in advancing the circular economy. Finally, persistent challenges are addressed, and future research directions are outlined, aiming to fully unlock the potential of fruit residues in promoting human health, environmental sustainability, and economic viability.
