Can unexploited biomass of Ficus carica L. be valorized as a bio-based material for the development of functional food formulations?

Abstract

Figs are a valuable source of nutrients including polyphenols, dietary fiber, and minerals. Cultivation and consumption of figs generates a considerable amount of by-products and waste which are also nutrient-rich. Fig unexploited mass can efficiently be valorized in the frame of circular bioeconomy for the development of functional foods, food supplements, cosmetics, and pharmaceuticals. Herein, we provide a thorough assessment of the chemical composition of figs toward the potential utilization of unexploited fig biomass for the generation of bio-based materials. Conventional and novel processes such as drying and extraction leading to the isolation of targeted ingredients are critically discussed.
