Effect of different drying methods on antioxidant characteristics of bee-pollen

In this study, microwave drying (MWD) and microwave-assisted vacuum drying (MW-VD) (500, 675 mbar) at power levels of 300, 450, 600 and 900 W, hot-air drying (HAD) and vacuum drying (VD) (300, 500 mbar) at temperatures of 35, 50, 65 °C and freeze drying (FD) of bee-pollen were investigated in relation to its total phenolic content (TPC), antioxidant vitamin composition (C and E) and antioxidant capacity. HAD at 35 °C provided similar vitamin C...
