Product Introduction

1. What is L-Theanine?

L-Theanine Powder is a characteristic amino acid in tea. It is synthesized by glutamic acid and ethylamine under the action of theanine synthetase in the root of tea trees. It is an important substance to form the taste of tea, mainly manifested as fresh and sweet, and is the main component of tea to generate saliva and moisten the sweet. 26 kinds of amino acids (6 kinds of non protein amino acids) were identified in tea, which generally accounted for 1%~5% of the dry weight of tea, while theanine accounted for more than 50% of the total free amino acids in tea. Theanine is an amino acid only contained in tea, and the content of theanine in tea is the largest. L-theanine is synthesized in the roots of tea trees, transferred to the leaves through the branches, and accumulated in the leaves. Under sunlight, theanine will be converted into catechins. Therefore, L-theanine content is higher in high-grade green tea cultivated in shade, but less in general coarse tea, and polyphenols content is higher.
