What Is Theanine Powder?

Theanine is a special ingredient that was first found in green tea. It is what gives tea its unique, savory taste. In fact, how much theanine is in a green tea is a very good sign of how high its quality is. The more theanine, the better the tea.

There are over 20 different amino acids in tea leaves, but theanine is the most important one. It makes up more than half of all the amino acids in tea.

In its pure form, theanine powder is a white, powdery crystal that resembles fine salt or sugar. It melts at a very high temperature. It dissolves easily in water, which is why you can taste it in your tea, but it won't dissolve in things like alcohol.

The flavor of theanine is a mix of a slight sweetness, like caramel, and a savory, brothy taste similar to monosodium glutamate (MSG). You only need a tiny, tiny amount of it to taste it.

 

 

 

What Is L-Theanine Powder Used For? 

● Health food

Theanine Powder is a health food that does not have hypnosis. For this reason, theanine won the research department award at the International Food Raw Materials Conference held in Germany in 1998. Theanine is the amino acid with the highest content in tea, accounting for more than 50% of the total free amino acids and 1%-2% of the dry weight of tea leaves. Theanine is a white needle-like body, easily soluble in water, has a sweet and refreshing taste, and is a component of the taste of tea.

 

● Tea beverage quality improver

Theanine Powder is the main component of the fresh and refreshing taste of tea, and can alleviate the bitter taste of caffeine and tea polyphenols. Therefore, in the production process of tea beverages, adding a certain amount of theanine can significantly improve the quality and flavor of tea beverages. 

 

● Functional Food Additives

Theanine Powder has the functions of enhancing the intensity of alpha waves in the brain, making people feel relaxed and improving memory, and has been confirmed by human experiments. Therefore, it can be added to food as a functional ingredient to develop nervous tension-relieving and intellectual functional food. Such as black tea concentrated extract (Bx=20) 5%, filling (Bx=7.5) 5%, granulated sugar 15%, gelling agent 1%, theanine 0.2%, citric acid 0.2%, sodium citrate 0.2%, Add water to 100% to make black tea jelly.

The brain waves were measured 60 minutes after eating, and measured once every 5 minutes. It was found that the amount of alpha waves immediately increased after eating, and it increased significantly after 30 minutes, up to 1.6 times. Studies have also confirmed that theanine can be added to candy, various beverages, etc. to obtain a very good sedative effect. Japan is actively carrying out research and development work in this area.

 

● Improve Flavor

Theanine powder can not only be used as a flavor modifier of green tea, but also can inhibit bitterness and astringency in other foods to improve the flavor of food. Great progress has been made in the study of theanine, especially its pharmacological effects. But there are still many problems. It is believed that with the deepening of research, it will have broader development and application prospects in the fields of food and medicine.

 

● Security Information

As early as 1985, the U.S. Food and Drug Administration (FDA) recognized theanine and confirmed that synthetic theanine is generally recognized as a safe substance (GRAS). And there is no limit in the use process. Its safety experiment shows that the acute toxicity of theanine in rats is above 5g/kg. In the subacute experiment of theanine taking continuously for 28 days (2g/kg per day), there is no toxic reaction in rats.

In the mutagenic experiment, theanine powder has not been found to have any mutagenic effect. The bacterial recovery mutation experiment also proved that it did not lead to gene mutation. With good safety and stability, theanine has been widely used in foods such as beverages, baked snacks, frozen snacks, etc. In addition, the special properties and biological activities of theanine make it also play an important role in food.
