This study was to investigate the physiological activity of cookies with green tea and black tea powder using catechin contents, total phenolic contents, nitrite scavenging ability, DPPH radical scavenging activity. Our results showed that total phenolic contents in tea powder and cookie was that green tea was higher than black tea in all levels. The catechin contents was 605.11 ± 12.95 μg/g in green tea powder, 44.22 ± 0.90 μg/g in green tea cookie, but not detected in black tea powder and cookie. In the nitrite scavenging ability, green tea powder was higher than black tea powder in all levels, but green tea cookie was higher than black tea cookie in highest level. In the DPPH radical scavenging activity, green tea was higher than black tea in powder and cookie in middle levels. In highest level and lowest level of powder and cookie, DPPH radical scavenging activity was not significant difference. This study was to provide basic data on physiological activity of green tea, black tea and cookie containing tea that will be useful for the developing green tea and black tea products.
