    This study investigated the quality characteristics of Yakgwa prepared with 0, 0.5, 1.0, 1.5, and 2.0% Ecklonia cava powder. As the concentration of Ecklonia cava powder increased, moisture, crude ash, crude fat, expansion rate, oil absorption rate, and hardness increased, while carbohydrate content, pH, and soluble solid content decreased. Lightness decreased, whereas redness and yellowness increased with higher powder levels. Total polyphenol content and ABTS radical scavenging activity significantly increased. Furthermore, the acid and peroxide values during storage were lower in the Ecklonia cava powder-added groups compared to the control. Sensory evaluation revealed that the 1.5% sample exhibited the highest overall acceptability. These findings suggest that Ecklonia cava powder can enhance the antioxidant activity and oxidative stability of Yakgwa, with 1.5% being the most suitable addition level when considering both quality characteristics and sensory acceptability.
