Functional Ingredients from Food Waste and By-Products

The increasing global concern over food loss and waste, along with its environmental, economic, and social consequences, accentuates the urgent need for effective mitigation strategies. Addressing food waste offers benefits for the climate, food security, and the sustainability of the agri-food system.

This Special Issue brings together cutting-edge research and practical approaches aimed at transforming food residues, discards, and surpluses into valuable functional ingredients and products. Covering a broad range of topics, this collection explores state-of-the-art upcycling strategies and expands knowledge on the characterization of bioactive compounds, ingredients and products derived from food by-products, and explores their diverse applications across sectors such as food, beverages, packaging, and agriculture.
