Abstract
This study aimed to investigate the effects of different cooking methods (boiling for 5 min and 8 min, microwave cooking for 3.5 min and 6.5 min, and stir-fry for 5 min and 10 min) on wild chard's antioxidant activity and total phenolic content. It was determined that the total phenolic content [1 552.00 ±Â 299.82 mg GAE·(100 g)–1, GAE – gallic acid equivalents] increased in 3.5 min in the microwave [2 611.33 ±Â 311.76 mg GAE·(100 g)–1] and 5 min in stir-frying [2 434.33 ±Â 197.75 mg GAE·(100 g)–1] compared to the raw chard samples (P < 0.05). Two different antioxidant activity determination methods [2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and ferric reducing antioxidant power (FRAP)] were used in the study. In both methods, it was determined that antioxidant activity decreased in the 10-min application of stir-frying. In contrast, the antioxidant activity increased by applying 3.5 min and 6.5 min in the microwave (P < 0.05). As a result, it was found that the antioxidant activity and total phenol content of wild chard changed when the cooking method and time were changed.
