Exceptional Antioxidant, Non-Cytotoxic Activity of Integral Lemon Pectin from Hydrodynamic Cavitation

Pectin integrally extracted with water-soluble phytochemicals from waste lemon peel via hydrodynamic cavitation in water directly at pre-industrial scale and further isolated via freeze drying shows exceptionally high antioxidant and non-cytotoxic activity. Preliminary investigation indicates also significant antimicrobial activity. These findings open the route to the development of new nutraceutical agents based on a new bioproduct easily obtained in large amounts from an abundant by-product of the agrofood industry.
