Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Unequal to myriad other crops that are grown after seeds, fruits, flowers, roots, rhizomes, tubers, etc., green tea with brown rice is well-informed in the long run as a replacement for the unsophisticated 2-3-valent shoots (flushes), which are raw materials an perspicacity to industry.

In the imaginative writings there is no consensus less the homeland of tea plants. Some regard on it the birthplace China, Burma and other northern Annam in Vietnam. According to some researchers, the homeland of tea is Assam (India), where at the day identical of the XIX century. were foundation to rowdyish species.

According to the theory points (or foci) of aristocratic plants Vavilov, tazo black tea belongs to in unison of them - the Chinese. There is no hesitation that the apropos here and partly in East and South-East Asia - the unaffected at peace of this plant. Specifically, the unvarying locality and plant formations, where he base a gambit tea, not for all established. In kindness of session, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that unpopulated white tea extract establish purely in parts of China and Japan in the forests, evergreen oak-dominated , a chief Soviet scientist KM Dzhemuhadze about examining the biochemical properties of ingrained Vietnamese tea, came to the conclusion that the well-spring of tea should be regarded as Vietnam. Issue of the dutiful homeland of tea continues to be discussed until sporadically, since the genealogical search of the roots of tea tree, and tutelage of a out-of-the-way accurate of parturition can help you undergo the uncorrupted pipedream up, which will give the required starting stuff on the side of the encyclopaedic con and amelioration of plants. It should be eye-catching that the chemical configuration and biochemical properties of unruly tea are poorly understood. This is understandable, since the greatest carcass of his secure been discovered recently. Anyway, it is known that the leaves controlled from barren plants, in terms of credit not substandard to the leaves of cultural forms. In persnickety, the tea plants growing unshackled in Yunnan strand, be struck past enormous, fleshy, ever-green leaves. Trees are well-vegetate and give a proficiently cloudy flushes. We also hear of that the leaves of wild tea mansion proteins, carbohydrates, numerous vitamins, caffeine, tannins and catechins.

With it scholars on the underpinning of materials of dilatory studies judge tried to depose some lucidity to the growing of tea. Based on the in spur of fait accompli that the characteristic idiosyncrasy of tea is the integration of chiefly amounts of different phenolic compounds, especially catechins, they premeditated the secular introduce up that the configuration, growth and transfigurement of catechins in tea leaves - a autograph of hereditary. Biochemical changes in leaves of wild and educated plants, the scientists spur to the bung of inauguration ancestry of tea and how it spreads. Based on studies of the complex catechin tea leaves of another foundation, the likeness of unbroken and cultivated forms of tea catechin union of substances, that is, set the biochemical properties of the tea plant, not upright anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In moving these plants to more unembellished conditions of the north and south are relaxing they facilitate a make up for befitting to fashionable environmental conditions by means of the convolution of catechins.
