Technological Processes to Produce Novel Ingredients From Agri-Food Sources: Functional Compounds From Citrus Wastes

Abstract

Citrus fruits of industrial interest include lemons, oranges, mandarins, grapefruits, clementines, limes and other commercially minor ones. A huge amount of agricultural waste is generated yearly all over the globe by citrus fruit industry. The wastes from these productions may be, however, of great nutritional and economic value for their chemical composition, due to their abundance of diverse functional compounds. Citrus fruits are extensively cultivated in any part of the world, therefore recovery and reuse of their waste is mandatory to reduce the environmental impact, to promote circular economy, to reduce waste of functional compounds and to obtain value-added products by economically advantageous processes.
