초록

Cold water extractable tea leaf is prepared by treatment of fresh green tea with the enzyme tannase under anaerobic conditions. The cold water extractable tea leaf is also used to prepare an instant tea product.

대표
청구항

A cold water extractable fired black tea leaf prepared by comminuting freshly harvested green tea leaf, treating the comminuted fresh green tea leaf with tannase at a temperature and for a time sufficient to impart a substantial cold water extractability to the manufactured tea leaf, fermenting the treated green tea leaf and firing the fermented tea leaf to reduce the moisture content of the tea leaf to below about 5% and produce a cold water extractable fired black tea leaf.
