Description

L-theanine is a colorless needle-like crystal with a melting point ranging from 217 to 218℃. L-Theanine is highly soluble in water, and its aqueous solution is slightly acidic, with a caramel aroma and the fresh and refreshing taste of monosodium glutamate. Insoluble in anhydrous ethanol and anhydrous ether; L-theanine can be hydrolyzed to form L-glutamic acid and ethylamine when exposed to strong acid. The color reaction of ninhydrin shows purple, and it reacts with basic copper carbonate to form a pale purple columnar copper salt. L-theanine is stable in nature and does not change during the usual food processing and sterilization.

Advantages:

Improving sleep quality: L-theanine can shorten the time it takes to fall asleep and enhance deep sleep.
Enhancing cognition: L-theanine and caffeine work together to improve attention and reaction speed (such as in energy drink applications).
Emotional regulation: L-theanine may increase the levels of dopamine and serotonin.
Antioxidation: L-theanine helps eliminate free radicals and delays cellular oxidation.

Application

Synergistic caffeine:
The combination of L-theanine and caffeine can enhance attention and reaction speed, while alleviating the tension or anxiety caused by caffeine.
Functional tea beverages:
L-theanine is added to bottled green tea, oolong tea, etc., to enhance the dual effects of "relaxation and refreshing".
Stress-relieving snacks:
For instance, L-theanine is added to chocolate, gummy candies and energy bars, claiming functions such as "relieving stress" and "enhancing concentration".
Salty foods:
L-theanine utilizes its umami flavor (similar to sodium glutamate) for flavoring potato chips, nuts, etc., reducing the addition of salt.
Sleep-inducing yogurt/milk:
Combined with gamma-aminobutyric acid or melatonin, it focuses on the function of relaxing and promoting sleep at night.
Substitute food:
L-theanine, as a functional component, enhances satiety and emotional stability.
Baked goods:
L-theanine is added to whole wheat or low-sugar products.
Sports drinks/protein powder:
L-theanine helps athletes relieve training stress and promote recovery after exercise.
