Five different cooking methods were tested: fresh-cut, boiling, steaming, microwaving and conventional stir-frying. For boiling, 300 g of homogeneous pieces of red cabbage were immersed in 800 ml of boiling water. The materials were drained off after being boiled for 5 min. For stir-frying, the blend oil (10 ml) was pre heated to 130ºC in a wok and materials (300 g) was stir-fried for 5 min. For microwave, 300 g of samples were placed in a plate and 10 ml of water was added to prevent red cabbage from being burned during cooking. A microwave oven at full power (450 W) for 5 min was used for microwaving. Steaming was conducted by suspending 300 g of red cabbage above 200 ml of boiling water for 5 min in a steamer with a lid. In addition, 300 g of red cabbage was collected for fresh-cut samples. At the end of each cooking treatment, the materials were frozen by liquid nitrogen and kept in polyethylene bags at –20ºC for further analysis.
