Nowadays, a massive quantity of byproducts is generated due to the fast-growing food processing industry. Many of these byproducts are rich in dietary, functional, and novel fibre sources with wide potential to be employed across the food, nutraceutical, and materials sectors. In this sense, understanding the potential role of the fibre of agrifood byproducts in reducing carbon footprint and fostering sustainable diets has become a goal line of the Bioactives and Bioproducts Research Group.
