초록

This study was conducted to investigate the effect of chestnut inner shell powder on antioxidant activity and the quality characteristics of cookies. Cookies were prepared with different amounts of chestnut inner shell powder(in ratios of 0, 0.5, 1, 3 and 5% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenol content in chestnut inner shell powder and cookies. For analyzing quality characteristics, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. The spread ratio, a values, total phenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing chestnut inner shell powder(p<0.001), while the pH of the dough, L values and b values of the cookies significantly decreased with increasing chestnut inner shell powder content(p<0.001). The consumer acceptability score for the 3% chestnut inner shell cookie groups ranked significantly higher(p<0.01) than those of the other groups in overall preference, flavor, taste and color. From these results, we suggest that chestnut inner shell is a good ingredient for increasing the consumer acceptability and the functionality of cookies.
