Abstract
The invention relates to a process for producing a preparation containing the polyphenols of green tea (Thea chinensis) in readily available, unoxidised form, in which fresh green tea leaves are cooled until the activity of the phenol oxidases therein has dropped to at most 1% of the value at normal temperature and at the same time or immediately afterwards the water acting as the reaction medium is removed. Products made by this process are packed in capsules soluble in hot water.
