This study investigated the potential of adding Curcuma longa powder to Yaksik (Korean traditional sweet) as a health food. The ash content, total phenol content, and antioxidant activity of the Yaksik significantly increased with increasing amounts of Curcuma longa powder, while the sweetness and lightness decreased, and the yellowness increased. Sensory evaluation revealed that the 1% Curcuma longa addition group was the most preferable.
