Abstract

Citrus fruits are products of great market values, as used by the juice industry in huge quantities. The juice industry processes millions of tons of citrus fruits per year, but only the pulp is utilized, whereas peels, seeds, and membrane residues are mostly discarded. This generates vast amounts of byproducts (>100 million tons/year), since the peel can make up to 50% of the weight of the fresh fruit. Phytochemical investigations showed that citrus peels are great sources of bioactive compounds, e.g., phenolic compounds, carotenoids, and monoterpenes. These compounds could find numerous applications in the food, cosmetics, and pharmaceutical industries. The recovery of the phytochemicals would provide economic and environmental benefits. Researchers worldwide have developed innovative techniques to recover phytochemicals from the citrus waste, by endorsing the international waste-prevention policies. This chapter reviews the advances in the sector of food technology applied to citrus chemistry and describes the available green techniques that allow the recovery of phytochemicals from citrus byproducts.

Keywords: Carotenoids; Green technologies; Monoterpenes; Phenolic compounds; Waste.
