Citrus peels waste as a source of value-added compounds: extraction and quantification of bioactive polyphenols
Previous analysis of citrus peels has demonstrated high content of biologically active polyphenols, with significant quantities of flavonoids and phenolic acids present. Both these compounds have been associated with antioxidant, anti-inflammatory, antiproliferative, anti-allergic, antiviral, anticarcinogenic, neuroprotective, and antimicrobial properties.
A recent paper points out that citrus peel waste alone makes up nearly 50% of wet fruit mass discarded as waste and proposes extraction of polyphenols to minimize waste. The bioactive substances in peels can be used in dietary supplements, cosmetics, food products, and pharmaceutical products.
Citrus peels contain significant polyphenols, compounds which have health benefits ranging from antioxidant to anticancer. Polyphenols are also found in large quantities in cannabis, undoubtedly contributing to it many of its well-known health benefits.
