Premium & Organic Matcha & Tea GB Biotona tea range The tea plant – Camellia sinensis 100% pure & natural Tea is one of the most widely consumed beverages in the world and contains a variety of interesting nutrients. It is made from the leaves of the Camellia sinensis, an evergreen plant from China, which later spread to India, Japan and its consumption to Europe and Russia. Although the same plant is used for green tea, white tea, black tea and Pu-Erh tea, it is possible obtain different tea varieties by processing the leaves in a different way. For example, green and white tea are neither oxidized nor fermented, black tea is fully oxidized and Pu-Erh tea is oxidized and post-fermented. Oxidation and fermentation alter the flavour profile, the chemical composition and the appearance of the tea. Green tea leaves consist of 15%-20% proteins, of which enzymes represent the largest share; amino acids (1-4%) (such as L-theanine), carbohydrates (5-7%), lipids (linoleic acid and alpha- linolenic acid), vitamins (B, C and E) and minerals. Moreover, green tea leaves also contain secondary phytochemicals, like the xanthine bases caffeine and theophylline, as well as sterols and pigments such as carotenoids and chlorophyll. L-theanine from green tea is one of the most efficient relaxing substances nature has to offer. But tea also contains tea caffeine (theine), which in turn produces a stimulating effect on the nervous system. L-theanine and caffeine have a synergetic effect on the improvement of mental alertness. Furthermore, caffeine increases fat burning and energy release. These effects are partially influenced by the presence of theophylline, which, in addition to a diuretic working, also has a stimulating influence on the respiratory system. Theine or caffeine? ➡ Theine and caffeine are in fact the same chemical molecules. They nevertheless produce a different effect within our body. When tea leaves are infused in water, the theine will bind with the tannins.
