Theanine was discovered in green tea in 1949 and isolated from Yulu tea leaves in 1950 , accounting for approximately 1-2% of the dry weight of green tea .
Theanine typically refers to L-theanine (levo-form), which is the natural form found in tea leaves, while research on D-theanine (dextro-form) is less extensive . As a dietary supplement, the US Food and Drug Administration deems it safe to consume up to 250 mg per day . Common dosage forms include capsules, tablets, and powders, and it is often used in combination with caffeine.
L-theanine can cross the blood-brain barrier and may possess neuromodulatory functions through interacting with glutamate receptors. Animal experiments have demonstrated its potential sedative and immunomodulatory effects. However, the European Food Safety Authority has assessed that the current evidence is insufficient to support a causal relationship between L-theanine and improving cognitive function, relieving psychological stress, maintaining normal sleep, or alleviating menstrual discomfort .
Potassium Bicarbonate is used as a raw material producing potassium carbonate, potassium acetate and potassium arsenite . Also it is a fire-extinguishing agent for oil and chemicals. It is used in medicine and baking powder.
Sucralose FCC USP is a low-calorie artificial sweetener made from sugar. Sucralose is the newest non-nutritive sweetener on the market. It is about 400 times as sweet as sucrose (Table Sugar).It can be used in baking or products that require a longer shelf life. Sucralose-based products stems from its favorable comparison to other low-calorie sweeteners in terms of taste and stability. It used as a Bulk Sweetening Agent, Unique Dental Benefits, Cooling, Flavor Enhancer and Humectant. The FCC grade meets the requirements of the Food Chemical Codex indicates and is suitable for all food, beverage and nutritional supplement applications. USP, or United States Pharmacopeia, grade chemicals comply with the standards of the United States Pharmacopeia and National Formulary (USP-NF). USP Grade chemicals are fit for use in food, drugs, and medicines. They are subject to stringent testing and are typically required to have the highest level of purity.

Tetrasodium pyrophosphate Food Grade is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing tetrasodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer. Tetrasodium pyrophosphate is sometimes used in household detergents to prevent similar deposition on clothing; it is used in household and industrial cleaning compounds, as a water softener, metal cleaner and for oil well drilling.
