The tea plant is one of the most consumed as beverages in the world’s oldest and widely which ranks second after water among non-alcoholic beverages. Our country is 7th in terms of agricultural areas allocated to tea plant (Camellia sinensis, (L)), and it is 5th in dry tea production in the World. Consuming so much tea has led scientists to investigate the effects of tea on health. These studies have shown that bioactive components in the tea have antimutagenic, anticarcinogenic, antibacterial, antiallergic and antioxidant properties. Tea is an important agricultural product in the Eastern Black Sea Region and employs approximately 22500 families. However, in our country, tea is consumed only as a beverage and as a small amount of by-products. The rich bioactive content of tea is too much to be underestimated. Also, considering the production of tea in our country, it is seen that it does not create enough added value and it does not one of the non-tea product's market.
For this reason, the aim of this study is to introduce the quality of the regional teas and to evaluate the processability of the non-tea products other than drinking tea which is in the first place in the world and provide important employment for our people.
