Abstract
National tea competition was held in Mie Prefecture in 1994. Major tea components (total nitrogen, total free amino acids, tannin, caffeine, ascorbic acid and seven major individual amino acids) in the prized teas ; Gyokuro, Ten-cha, Kabuse-cha, Ordinary Sen-cha, Fukamushi Sen-cha, Mushisei Tamaryoku-cha and Kamairisei Tamaryoku-cha, at the competition were analyzed. The average contents of total nitrogen of these teas were 7.23 %, 7.07 %, 6.78 %, 7.12 %, 6.65 %, 6.89 % and 6.23 %, respectively. These teas contained much higher levels of total nitrogen, caffeine and individual amino acids than the teas in the market.
