The content of ascorbic acid in tea leaves decreased to about 82 and 69% after five days storage at 5 and 30℃, respectively. However, in stored leaves at 5℃, about 76% of initial content of ascorbic acid was remained after 10 days storage. In defrosted tea leaves, the decomposition of ascorbic acid was observed., 紀要論文}, pages = {231--233}, title = {第 8 報 貯蔵による茶葉のビタミン C の変化(茶に関する研究)(農芸化学科)}, year = {1983} }
