    Product Introduction

    L-Theanine is an amino acid unique to tea, with the chemical formula C7H14N2O3, which makes up 1%-2% by weight in dry tea.

    Theanine was first isolated from green tea in 1950. It is a characteristic amino acid of tea and one of the flavor substances of tea. It has a strong positive correlation with the quality of green tea, with a correlation coefficient of 0.787 to 0.876.Among the more than 20 kinds of amino acids present in tea, theanine accounts for about 50% to 60% of the total amino acids in tea. Research has found that, in addition to trace amounts of it being detected in plants such as sasanqua, mushrooms, and camellia oleifera, it is also present in other plants. have not yet been discovered.

    01. Improve the taste of beverages. Theanine is the main component of the refreshing taste of tea, and can alleviate the bitterness of caffeine and the bitterness of tea polyphenols. Currently, tea beverages in my country have poor freshness due to limitations in processing technology. Therefore, a certain amount of theanine can be added during the production process of tea beverages, which can significantly improve the quality of tea beverages.Theanine is added to the newly developed "raw tea" beverage developed by Japan's Kirin Company.

    02. Improve food flavor
    Studies have shown that theanine can improve the bitterness of coffee, cocoa, ginseng drinks, grapefruit drinks, beer, reduce the astringency of wine, so it can be used as a flavor modifier for these foods. Moreover, theanine is relatively stable under normal food processing conditions (such as sterilization, pH and heating, etc.), so it has a wide range of applications.

    03. Functional food additives
    Theanine can enhance the intensity of alpha waves in the brain, make people feel relaxed and improve memory, and has been tested in humans. Therefore, functional foods can be developed to relieve nervous tension and improve brain function.
