This chapter will first look at recent literature on various natural antioxidants that can be extracted from agro-industrial by-products, such as fruits and vegetable by-products (skin, peels, pomace, seeds, husk, etc.), grains and oilseeds by-products (bran, press cakes, meal, etc.), and dairy, meat, and poultry by-products (whey, skin, viscera, etc.). Then, traditional and emerging techniques used to recover these natural antioxidants from agro-industrial waste and by-products will be discussed, and examples of their applications in various food categories will be presented. Finally, limitations, future prospects, and conclusions will be described. © 2024 Elsevier Inc.
