Introduction to L-Theanine

L-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.

Physical and chemical properties of L-Theanine

L-Theanine that exists naturally is L-type. The pure product is white needle crystal with a melting point of 217°C to 218°C and a specific optical rotation [α]D20=0.7°. It is extremely soluble in water and insoluble in organic solvents such as ethanol and ether. The aqueous solution is slightly acidic, with a caramel aroma and a refreshing taste similar to MSG. The taste threshold is 0.06%.

Extraction method of L-Theanine

1. Gas Chromatography

Gas chromatography is a commonly used method to extract theanine. First, the theanine in tea leaves is extracted by dissolving with dilute acid, and then measured using a high-performance liquid chromatograph. Through chromatographic column separation and identification, the content of theanine is finally obtained.

2. Ultrasonic method

Ultrasonic method is a very effective method for extracting theanine. The high-frequency vibration of ultrasonic waves can break the tea cells and release theanine quickly. Then through solvent extraction, the theanine solution can be obtained, and then through concentration and drying, the theanine extract can finally be obtained.

3. Enzymatic method

The enzymatic method is a relatively new method for extracting theanine. Tea powder is first mixed with specific enzymes to release theanine. Then through centrifugation, filtration and other steps, the extract of theanine is obtained. Due to the selective destruction of tea cells by enzymes, the extraction effect of theanine is very good.
