The aim of this work is to investigate the effects of domestic cooking methods, including steaming, microwave heating, boiling and stir-frying on the nutritional quality of red cabbage. Compared with fresh-cut
red cabbage, all cooking methods were found to cause significant reduction in anthocyanin and total
glucosinolates contents. Moreover, steaming resulted in significantly greater retention of vitamin C
and DPPH radical-scavenging activity, while stir-frying and boiling, two popular Chinese cooking methods, led to significant losses of total phenolic, vitamin C, DPPH radical-scavenging activity, and total soluble sugar as well as reducing sugars. Normally, red cabbage consumed fresh in salads could maintain the
highest nutrition. However, considering the habits of Asian cuisine, it is recommended to use less water
and less cooking time, such as steaming based on our present results, so as to retain the optimum benefits
of the health-promoting compounds.
