Abstract

To test the practical applicability of the rapid tannin., test with potassium bichromate, the correlation between the tannin content and the reaction of the tea leaves to potassium bichromate was examined.
No correlation was obtained, so this method is not applicable to the tannin test of the tea leaves.
