Online ahead of print.ABSTRACTStone fruits such as peaches, plums, nectarines, and apricots contribute significantly to global nutrition and agricultural economies. However, substantial losses occur at both pre- and post-harvest stages due to unfavorable weather conditions, market-driven cosmetic standards, and inefficiencies in harvesting, transport, and storage. Additionally, by-products from industrial processing such as pomace, peels, stones, and seeds are often discarded despite being rich in bioactive compounds such as dietary fibers, polyphenols, antioxidants, natural pigments (e.g., anthocyanins and carotenoids), and healthy fats. This review critically examines the scale, causes, and composition of stone fruit waste globally across regions and identifies valuable constituents in discarded materials. It evaluates current and emerging valorization strategies such as the production of dry fruits, powders, oils, and extracts for applications in the food, cosmetic, and pharmaceutical sectors. By highlighting opportunities for waste reduction and resource recovery, this review supports the development of sustainable value chains and circular economy practices. It concludes that overcoming technological, economic, and regulatory barriers through coordinated efforts across research, industry, and policy is essential to realize the full potential of stone fruit waste valorization and contribute meaningfully to global sustainability goals.PMID:42334377 | DOI:10.1080/10408398.2026.2690035
