Black and Green Tea – Traditionally Healthy

[1] Hänsel R. et al.: Hagers Handbuch der Pharmazeutischen Praxis, (1994) Vol. 4, Springer-Verlag Berlin, 5th Ed., [2] Lorist M. M., Snel J., Kok A., Mulder G.: Influence of caffeine on selective attention in well-rested and fatigued subjects, Psychophysiology (1994) 31: 525-534

Known for thousands of years, tea (Camellia sinensis) is a plant that has become famous throughout the world as a hot beverage. The tea bush grows in warm, tropical highlands and is kept to a height of approx. 1 meter through regular cutting and picking. The best qual-ity is obtained if only the top two leaves and the bud are plucked during harvesting. The world’s most important cultivation areas include China, India, Sri Lanka, Indonesia and some African countries.

Health from natureTea contains all sorts of physiologically effective substances. Green Tea, in particular, is known for its functional and healing effects. Since the leaves have not been subjected to oxidation by enzymes, the polyphenols contained in Green Tea are primarily catechins, including epi-gallocatechin gallate (EGCG), which is a particularly powerful bioactive agent. The first thing we notice when enjoying a cup of tea is its stimulating effect. The caffeine that it contains releases such messenger substances in the brain as dopamine or serotonin, which stimulate the central nervous system and consi-derably improve our mental capacity [1]. This effect was proven in the course of extensive tests conducted in the mid 1990s [2].

Green Tea, Black Tea, White Tea, Oolong Tea or Pu-Erh–Tea – they all come from the same plant: Camellia sinensis. With Black Tea, the phenolic substances of the leaves are oxidised by enzymes contained in the cell’s own juices, which react with aerial oxygen. During this process, the monomeric polyphenols of the leaf, such as catechin, epicatechin, epigallocatechin or epigallo-catechin gallate, polymerise into different long chained polyphenols like theaflavine or thearubigine.

This process is shortened for Oolong Tea, while Green and White Tea are made from unfermented leaves.

It is necessary to deactivate the enzymes responsible for polyphenol oxidation in the Green Tea manufacturing process. The freshly plucked tea leaves are heated up by steaming or pan firing.

As far as White Tea is con-cerned, the plucked tea leaves are dried immediately, without any further process-ing. The best grade of White Tea is made by plucking just the unopened young shoots of the tea bush, which are immediately dried in the sun. This type is referred to as “silver needle” because of the tiny silvery hairs on the buds. Bai Mu Dan is another popular type, which is produced by plucking a pro portion of two leaves and a bud and these are also just dried in the sun after plucking. White Tea therefore comes closest to the natural product actually grown on the plantation.

The Pu-Erh–Tea manufac-turing process is the other extreme, in which the fresh tea leaves are oxidised for an extremely long period lasting between three and 30 years. Oxidation takes place under controlled temperature and humidity conditions. This production process gives Pu-Erh–Tea its typically earthy taste and an extremely dark brew.

Functional Properties

A stimulating drink and a medicinal plantWhat makes Green Tea spe-cial is its reported capacity to prevent cancer, strokes, heart attacks, high blood pressure and many other, often serious illnesses. This is primarily due to its antioxidant potential, i.e. its reaction to the free radicals which are constantly being created during meta-bolic processes. Also known as Reactive Oxygen Species (ROS), these free radicals attack the human cell struc-tures and damage the DNA. Our cells contain the body’s enzymes, which are able to neutralise the quantities of ROS that occur under nor-mal conditions. A surplus of free radicals can also build

up as a result of stress, environmental pollution, diet and many other factors, however, and this can have undesirable consequences. Free radicals can accelerate the aging process, damage blood vessels and are thought to cause many forms of can-cer by reacting with DNA (3).

Natural antioxidantsAntioxidants that are absorbed with food, such as vitamins C and E, which trap the free radicals in the body, can provide protection against damage of this type. The Green Tea polyphenols (GTP) are among the strongest natural antioxidants (4). Their antioxidative potential is 20 to 30 times stronger thanthat of vitamins C and E (5).

Tests have demonstrated a resistance to carcinogenic substances after the admin-istration of Green Tea. In irradiation tests, the regular addition of GTP to drinking water produced increased resistance to skin cancer (6). Studies indicate that poly-phenols from Green Tea can slow down the growth of tumour cells in the breast, large intestine, lungs and skin (7) – results which clearly prove that Green Tea can help prevent a wide range of cancers.

Studies in Japan and the U.S.Epidemiological studies from Japan also substantiate the anticancer effect of Green Tea as found in laboratory trials: In the Prefecture of Shizuoka, an area in which large quan-tities of Green Tea are con-sumed (around 8 to 9 cups a day), the mortality rate from cancers is well below the Japanese average (8). A study carried out on 472 American breast cancer patients also showed that drinking Green Tea was able to clearly reduce the renewed formation of cancer cells after an operation (9).

Get fit with Green TeaWhile discussing the health-promoting properties of Green Tea, we must be sure to mention its antibacterial effects as well, including the way it affects caries bacteria, for example, or bleeding gums (10). Furthermore, Green Tea has also been found to promote weight loss in tests performed on animals, even where food with a high fat content was administered at the same time (11). This effect has now also been demon-strated in humans (12), provid-ing yet further proof of the amazing healing powers of the ancient cultivated plant that is tea.

Green Tea and CognitionPlantextrakt has conducted a scientific study to investigate the effects of a soft drink containing a decaffeinated Green Tea extract enriched with L-theanine and theo-gallin. The study was carried out with 12 healthy human volunteers in a randomised, placebo-controlled, crossover study. The results clearly showed neurophysiologi-cal effects located in frontal brain regions, indicating an improvement of cognitive function. (13, 14, 15)

Decaffeinated Teas and Tea Flavours

Decaffeinated Black, Green and White TeaPlantextrakt is the leading supplier of Decaffeinated Black, Green and White Teas worldwide. Decaffeinated teas have a high antioxidant potential that is well recog-nised by health-conscious consumers. Consumers who are sensitive to caffeine prefer decaffeinated teas, which are also very suitable for children. At Plantextrakt, decaffeinated teas are produced by means of a CO2 decaffeination process or using a direct method with ethyl acetate as the solvent.

No halogenated solvents, such as methylene chloride are used. The CO2 process is the preferable alternative for decaffeination of Green Tea, as caffeine is removed selectively while the majority of catechins remain in the product. Most Black Teas are decaffeinated by means of the direct method, using ethyl acetate.

Natural Tea FlavoursPlantextrakt has been processing tea for over 20 years. Our unique knowledge of the chemistry and indi-vidual characteristics of teas from different origins enables us to protect and maintain the highly sensitive and unique best flavour quality of the “two leaves and a bud”. This enables Plantextrakt to offer all Natural Tea Flavour-ings FTNF (From The Named Fruit), which are considered to be among the best Black and Green Tea Flavours available in the world.

These natural flavours are available in liquid and powdered form and are therefore suitable for virtu-ally any application, particu-larly including beverages and instant preparations. We are also able to offer liquid tea flavours with Kosher and Halal status as we have other solvents at our disposal apart from ethyl alcohol. Plant extrakt Natural Tea and Green Tea Flavours are clearly water soluble, colour-less to pale yellow and free of caffeine.
