Fresh juice from bergamot (Citrus bergamia Risso) has been studied to evaluate the polyphenolic composition by HPLC-DAD analysis and total polyphenols content by UV method. The main constituent, Naringin, has been selected as analytical and biological marker of the juice. Juice has been loaded onto maltodextrin matrix by spray-drying. The produced maltodextrin/juice powder (BMP) showed neither significant change in total polyphenols content nor decrease in antioxidant properties with respect to fresh juice. Moreover, BMP displayed high in vitro dissolution rate of the bioactive constituents in water and in simulated biological fluids. BMP appears as promising functional raw material for food, nutraceutical and pharmaceutical products. With this aim, a formulation study to develop tablets (BMT) for oral administration has been also performed. The produced solid oral dosage form preserved high polyphenols content, showed complete disaggregation in few minutes and satisfying dissolution rate of the bioactive constituents in simulated biological fluids.
