초록

This study examines the effects of different cooking methods (stir-frying, steaming, superheated-steaming) on the contents and the true retention of moisture, water-soluble vitamins, and bioactive compounds of ten selected vegetables: broccoli, brussels sprout, cabbage, eggplant, green bean, onion, red cabbage, red onion, squash, and tomato. The total color difference (ΔE) values were decreased after stir-frying the samples, except for eggplant, green bean, and tomato. The true retention of water-soluble vitamins (B1, B2, B3, and C) was increased in most vegetables after superheated-steaming, as compared to steaming and stir-frying. Moreover, compared to the uncooked vegetables, a higher true retention of total polyphenol and flavonoid was obtained for most vegetables subsequent to superheated-steaming. Total anthocyanin content was detected only in eggplant, red cabbage, and red onion, and a smaller loss of anthocyanin was determined after subjecting red cabbage to superheated-steaming. Also, the free radical scavenging activities were higher in superheatedsteaming vegetables, except in eggplant and squash. These results indicate that superheated-steaming induces a positive effect for retaining water-soluble vitamins and functional components of vegetables.
