This study examined the quality characteristics of cookies comprised of various amounts of barley-sprout powder by analyzing the physico-chemical characteristics of the cookies and investigating a sensory evaluation. For the study, the cookies were cooked with the following levels of barley-sprout powder: 0%, 3%, 6%, 9%, and 12%. The results show that the moisture content of the cookies was increased in accordance with the level of barley-sprout powder and this result is the same as the spreadability factor of the cookies (p<0.001). Also, the pH and brix values of the samples decreased in accordance with the level of barley-sprout powder (p<0.001). Regarding hunter's colors, the values of L (lightness), a (redness), and b (yellowness) are significantly decreased, increasing the quantity of barley-sprout powder (p<0.001). For the textural characteristics, the results show that the hardness of the cookies decreased in accordance with the addition of the barleysprout powder; furthermore, the results indicate a tendency whereby the DPPH-radical-scavenging activity and the total polyphenol content of the cookies were increased, thereby increasing the quantity of the barley-sprout powder (p<0.001). For the sensory evaluation, the cookies that were made with 6 % barley-sprout powder received the highest scores in terms of appearance, taste, and overall preference (p<0.05, p<0.001). This study suggests that barley-sprout powder is an excellent ingredient for improving the acceptability and functionality of cookies, and that, in relation to the flour quantity the ideal proportion of barley-sprout powder is 6%.
