In this study, Boehmeria nivea were extracted with water and ethanol, and antioxidative activity was investigated along with the quality of cookies prepared with added Boehmeria nivea, as a functional food. Among the water and ethanol extracts, high electron donating abilities were found. we selected various quantities of Boehmeria nivea(0%, 3%, 6%, 9%, 12%, 15%) to add to the cookies as an independent variable and performed sensory tests, as well as, measured chromaticity, and property of matter measurements. The rates of brightness, redness, and yellowness(p<0.001) changed significantly with increasing quantities Boehmeria nivea. The rates for spread ratio, hardness, brittleness, and chewiness(p<0.001) also changed siginificantly with increasing amounts Boehmeria nivea. Finally, texture(p<0.05), appearness, sweetness(p<0.01), bitterness, and overall quality(p<0.001) were examined in sensory tests and showed significant differences. Based on the above results, the cookies that contained 3~9% of Boehmeria nivea presented the best quality.
