Tea stems contain a considerable amount of aroma substances which are transferred from stems to leaf buds in the tea processing. It is a must to have appropriate tea stems to produce the tea with high fragrance and thick taste.
Tea stems contain a considerable amount of aroma substances. The aroma of tea gradually decreased from the first leaf to the third leaf, while tea stems contain the highest aroma. Tea aroma substances mainly exist in the main veins of tea stems and young leaves; moreover, tender stems contain more amino acids (mainly theanine) than those in young leaves.
The vascular bundle in stems is the main inducing tissue for nutrient and aroma, most substances contained are water-soluble. In the tea processing, the aroma was transferred to the leaves from the stems along with the water evaporated.
