Development And Application Of L-Theanine

L-theanine is chemically named as N-ethyl-γ-L-glutamine (N-ethyl-γ-L-glutamine, Cas No.: 3081-61-6). The naturally occurring theanine in tea plants is L-Theanine, which accounts for 30% to 60% of free amino acids in tea, and is the most abundant amino acid in tea, generally accounting for 1% ~5% of the dry weight of tea.

Based on the special functional activity of theanine, it can be added to food as a functional ingredient to develop foods with corresponding functions.For example, functional foods for relieving nervous tension and nootropics, sports foods that can keep athletes awake, reduce mental stress, and exert competitive skills, and develop functional foods that prevent and improve sports fatigue.

With the anti-oxidation, anti-aging and moisturizing effects of theanine, skin care products such as creams and masks can be developed. Theanine used in feed can improve the immune function of yellow feather broilers in the early stage of growth and reduce the use of antibiotics in feed.

In the United States, in addition to using theanine to develop sleep-improving health products, it is also used to develop products that assist in the treatment of children's ADHD and improve learning/memory effects. The product forms are mainly capsules and oral liquids, as well as aerosols. Powder, chocolate, bulk theanine powder, etc.
