- Abstract
- This study was performed to evaluate the quality characteristics and antioxidative activities of cookies prepared with different amounts of purple sweet potato powder. Moisture and crude ash contents were lowest in the control group followed in order by the 10%, 20%, and 30%purple sweet potato powder addition groups. The lightness and yellowness values measured by Hunter color system decreased based on the amount of purple sweet potato powder concentration added to cookies. The total phenolic compound and anthocyanin contents were the highest in 30% purple sweet potato powder added cookies. The DPPH radical scavenging activity of 30% purple sweet potato powder added cookies showed the highest values among groups. In the sensory evaluation, the scores for taste, texture and overall preference were significantly highest in cookies with 10% and 20% purple sweet potato powder. Considering the scores of antioxidant activity and sensory evaluation, the concentration of between 10% and 20% addition of purple sweet potato powder would be ideal for development of functional cookies.
