Studies on the buffering capacity of green tea extracts suggest the pKa of the theanine amino group to be[10, 12]. The pKa of the carboxyl unit was not formally quantified due to interference from other acidic species. However, comparisons with close structural analogues such as glutamine suggest the value lies in the range 2.1-2.5[13] Theanine is stable under acidic conditions but undergoes base hydrolysis to yield glutamic acid and ethylamine[2, 14]. During infusion, theanine does not react chemically with any of the other tea components. This is in contrast to catechins, which can precipitate from solution as a result of π stacking interactions with caffeine[15, 16]or can react with proteins and enzymes such as lipoxygenase, α-amylase, pepsin, trypsin and lipase[15]. Health effects Green tea leaves have many beneficial health activities including anti-inflammatory, anti-carcinogenic, anti-mutagenic, antioxidative and antimicrobial and hypolipidemic effects[38, 39]. Those beneficial effects are largely originated from the biological effects from L-Theanine as below: Ingestion of theanine has been reported to facilitate the generation of alpha brain waves, which are associated with a relaxed but alert mental state[40]. In addition, theanine is reported to promote the release of the inhibitory neurotransmitter γ-aminobutyric acid [GABA], which in turn regulates dopamine and serotonin levels in the brain[41]. Thus, theanine consumption has been closely associated with relaxation and improved learning ability. Safety information FDA classified L-theanine as “generally recognized as safe.” This classification means that they believe this additive to be safe when people use it as the packaging suggests. Women who are pregnant or breastfeeding should not use L-theanine.

First aid measures

General advice Consult a physician. Show this material safety data sheet to the doctor in attendance. If inhaled If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact Wash off with soap and plenty of water. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

Firefighting measures

Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Special hazards arising from the substance or mixture Carbon oxides Nitrogen oxides (NOx) Advice for firefighters Wear self-contained breathing apparatus for firefighting if necessary.
