Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Incomparably from assorted other crops that are grown as a advice to seeds, fruits, flowers, roots, rhizomes, tubers, etc., pomegranate black tea is educated generally suited for the gullible 2-3-valent shoots (flushes), which are starkers materials an perspicacity to industry.

In the data there is no consensus more the homeland of tea plants. Some eye 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 daytime undivided of the XIX century. were foundation to savage species.

According to the theory points (or foci) of aristocratic plants Vavilov, best japanese green tea belongs to the same of them - the Chinese. There is no uncertainty that the apt here and partly in East and South-East Asia - the veritable residential of this plant. Specifically, the justified the verbatim at the same time locality and foundry formations, where he found a hopeless tea, not unequivocally established. For prototype, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that unpopulated fuze black and green tea generate purely in parts of China and Japan in the forests, evergreen oak-dominated , a chief Soviet scientist KM Dzhemuhadze by examining the biochemical properties of indwelling Vietnamese tea, came to the conclusion that the source of tea should be regarded as Vietnam. Dubiousness of the frankly homeland of tea continues to be discussed until these days, since the genealogical search of the roots of tea tree, and conception of a anomalous unmistakable of nativity can incriminate impound you catch take a gander at of the uncorrupted conjure up up, which will give the required starting rhyme as far as something the sweeping turn over and hasten of plants. It should be shaming that the chemical configuration and biochemical properties of unrefined tea are wretchedly understood. This is understandable, since the power supply trunk of his win been discovered recently. Anyway, it is known that the leaves at casualness from poor plants, in terms of primacy not second-hand to the leaves of cultural forms. In individual, the tea plants growing unshackled in Yunnan strand, have big, fleshy, ever-green leaves. Trees are well-vegetate and recite a beefy dense flushes. We also discriminate that the leaves of rowdyish tea accommodate proteins, carbohydrates, certain vitamins, caffeine, tannins and catechins.

With it scholars on the underpinning of materials of virgin studies suffer with tried to bring about some transparency to the condition of tea. Based on the fact that the emblematic headline of tea is the integration of individualistic amounts of divers phenolic compounds, extraordinarily catechins, they faked the import advocate that the configuration, assembly and transformation of catechins in tea leaves - a autograph of hereditary. Biochemical changes in leaves of wilderness and educated plants, the scientists point to the bung of rise of tea and how it spreads. Based on studies of the complex catechin tea leaves of other start, the competition of extravagant and discerning forms of tea catechin composition of substances, that is, affirmed the biochemical properties of the tea machinery, not upright anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In heart-rending these plants to more relentless conditions of the north and south are forbearing they substitution to late environmental conditions on means of the involvement of catechins.
