Method & Evidence

AimTo evaluate the performance of different hollow fiber ultrafiltration membranes in clarifying blood orange juice, focusing on their impact on productivity and the retention of key bioactive compounds.
MethodExperimental Investigation
ProcedureThree hollow fiber membrane modules made of polysulfone (PS) and polyacrylonitrile (PAN) with varying molecular weight cut-offs (50 and 100 kDa) were tested for blood orange juice clarification. The performance was assessed based on flux (productivity) and the rejection rates of total anthocyanin content (TAC), total phenolic content (TPC), and total antioxidant activity (TAA).
