Abstract

Organic and inorganic components of Shishikui-kancha produced in midwinter in Kaiyo, Tokushima, Japan, were analyzed. Compared to tea produced in spring, the organic components of Shishikui-kancha were higher in free sugars and lower in polyphenols, catechins, caffeine, and free amino acids. In terms of inorganic components, Shishikui-kancha contained higher concentrations of Ca, Al, Mn, Ba and Sr than tea produced in spring.
