Certificate Of Analysis

L-Theanine, a unique amino acid found in tea, has the chemical formula C7H14N2O3 and comprises 1-2% of dry tea weight. Structurally similar to brain-active substances like glutamine and glutamic acid, L-Theanine enhances saliva production and sweetness perception.

GreenHerb Biological Technology Co., Ltd. offers high-quality food-grade L-Theanine (98%) in loose powder form, free from clumping and visible impurities. As a versatile food additive, it’s perfect for dim sum, candy, jelly, beverages, and chewing gum. We have ample stock at competitive prices and provide free sample trials.

Certificate Of Analysis

Approach 1

Mixing L-glutamine with ethylamine derivatives and using glutaminase for conversion (CN 1977047A) effectively avoids D-theanine production. However, this method is lengthy, complex, and yields various products that are challenging to separate, requiring advanced equipment.

Approach 2

The synthesis method outlined in CN 1706816 A and CN 1690046 A, which involves reacting ethylamine with L-pyroglutamic acid, achieves a high overall yield. However, it requires anhydrous ethylamine and pressurized equipment, leading to significant industrial challenges and environmental risks. Additionally, this process can easily introduce D-theanine, compromising the quality of L-Theanine, which ideally should be 98% pure.

Approach 3

Using L-glutamine-5-ester to react with ethylamine yields amino-protected theanine, which can be deprotected to obtain theanine (CN 1789237). This method effectively prevents D-theanine introduction but involves a lengthy process and high costs. Additionally, D-theanine and DL-theanine are important raw materials for peptide synthesis and scientific research, with growing market demand. However, reports on their artificial synthesis remain limited.

Product Function

Most theanine has the effects and effects of relieving body fatigue, protecting nerve cells, assisting in blood pressure reduction, improving brain function, antibacterial and anti-inflammatory effects, etc. It needs to be used reasonably to avoid affecting health.

1、Relieve body fatigue: Most can improve sleep quality, help improve sleep quality, have the effect of relieving body fatigue, and have the effect of improving body fatigue and weakness.

2、Protecting nerve cells: It can affect the efficacy of nerve cells, improve nerve cell damage, and alleviate symptoms such as decreased muscle strength in the body.

3、Assisted antihypertensive therapy: beneficial for dilating blood vessels, reducing peripheral vascular resistance, having an auxiliary antihypertensive effect, improving hypertension, and relieving physical weakness.

4、Antibacterial and anti-inflammatory: It can kill bacteria and diminish inflammation, and can assist in the treatment of bacterial infectious diseases.

Application

Pharmaceutical Field

Anti-Tumor Drug: L-Theanine (98%) has shown promise in animal studies, delaying metastatic tumors and prolonging survival in leukemia-affected mice.
Antihypertensive Drug: High doses of theanine significantly lower systolic and diastolic blood pressure in vasopressor rats.
Sedative Ingredient: Theanine serves as an effective component in sedatives, potentially preventing conditions like Parkinson's disease, senile dementia, and nerve dysfunction.

Food Industry

As a new food additive, theanine boasts excellent processing characteristics and stability, making it suitable for various products, including dim sum, candy, jelly, beverages, and chewing gum.

Quality Improver for Tea Drinks: Adding theanine enhances the quality and flavor of tea beverages during production.
Flavor Enhancer: Theanine effectively reduces bitterness in coffee, cocoa, ginseng drinks, grapefruit drinks, and beer, while also mitigating wine's astringency. It remains stable under typical processing conditions, allowing for widespread application. Japan has successfully incorporated theanine into chocolate, jelly, pudding, chewing gum, health teas, and refreshing beverages.
Functional Food Additive: Theanine enhances brain alpha wave intensity, promoting relaxation and improving memory. This property supports the development of functional foods designed to alleviate stress and boost cognitive function.
