Understanding Decaffeinated Tea: Processes and Benefits

What is Decaffeinated Tea?
Decaffeinated tea refers to tea that has undergone a process to remove most of its caffeine content. Derived from the Camellia sinensis plant, typical tea varieties contain between 1.6 percent caffeine in Formosa broken leaf types to 4.5 percent in other common types.

To be labeled as decaffeinated, the U.S. Food & Drug Administration mandates that 97 percent of the 4.5 percent caffeine content must be removed. Despite this standard, some tea packers advertise their teas as 98 percent caffeine-free. These teas, however, are not truly decaffeinated but possess naturally low caffeine levels. It is crucial to distinguish between decaffeinated and caffeine-free labels; the latter only applies to herbal teas, not traditional teas.

Globally, there are two primary sources of decaffeinated tea, both processed by firms located in Europe. These teas are available in all leaf grades and a wide array of flavors, catering to diverse consumer preferences.

The decaffeination process employs one of three methods: methylene chloride, ethyl acetate, or carbon dioxide. Methylene chloride, once controversial due to health concerns, is now considered safe within regulated limits. Ethyl acetate, a naturally occurring compound found in fruits, provides a natural decaffeination method, albeit leaving a slight aftertaste. The carbon dioxide method, deemed the most effective and natural, preserves the tea’s flavor profile and beneficial compounds, making it a preferred choice among health-conscious consumers.

Health Benefits of Decaffeinated Tea
Decaffeinated tea offers numerous health benefits while eliminating the potential side effects of caffeine, such as insomnia and increased heart rate. It retains most of the antioxidants found in regular tea, which are essential for combating free radicals and reducing the risk of chronic diseases like heart disease and cancer.

Epigallocatechin gallate (EGCG) in green tea

Green tea, a beverage with a history spanning millennia, has garnered popularity and extensive research attesting to its myriad health benefits. Among these advantages is its potential to thwart cancer, combat infectious diseases, and notably, its role in promoting heart health through the presence of epigallocatechin gallate (EGCG), a crucial catechin in green tea.

Scientific findings suggest that EGCG, contained in green tea, may play a pivotal role in safeguarding cardiovascular well-being by reducing blood pressure, cholesterol levels, and the accumulation of arterial plaque—key factors linked to heart disease. Moreover, EGCG is believed to enhance both metabolic and vascular functions associated with insulin.

The acclaim surrounding EGCG is primarily rooted in its potent antioxidant properties and its potential to mitigate stress and inflammation. Research has highlighted that epigallocatechin exhibits antioxidative, anti-inflammatory, and antiatherogenic effects, employing pathways mediated by growth factors, the mitogen-activated protein kinase-dependent pathway, and the ubiquitin/proteasome degradation pathway.

The generation of free radicals, highly reactive particles capable of harming human cells, leads to oxidative stress when produced excessively. EGCG has demonstrated the capacity to scavenge these free radicals, showcasing additional positive effects in protecting cells and tissues throughout the body.

While EGCG stands out as the most extensively researched and potent catechin, other varieties such as epicatechin, epigallocatechin, and epicatechin 3-gallate may offer similar benefits. Notably, many of these catechins are readily available in various food sources.

• Tea may stop cavities
• Tea may fight virus
Major health benefits of tea

General benefits of drinking tea

Saves arteries
Drinking black tea helps prevent deadly clogging of arteries and reverses poor arterial functioning that can trigger heart attacks and strokes, two major new studies have found. In a large 10-year study in the Netherlands, men who consumed the amount of antioxidants called "catechins" found in three cups of black tea were 50% less likely to die of ischemic heart disease, caused by narrowed clogged arteries, than were men who consumed only the catechins in half a cup of tea.

Inhibits cancer growth
Tea has long been tied to a lower risk of stomach, colon and breast cancer, although the connection is not proven. Now lab studies find that tea chemicals actually may stop cancer growth. Rutgers University researchers showed that a compound in black tea called TF-2 caused colorectal cancer cells to "commit suicide"; normal cells were unaffected.  

Tames inflammation
Researchers at Case Western Reserve University gave arthritis-prone mice either green tea or water. The human equivalent of four cups of green tea daily halved the mice's risk of developing arthritis. Also intriguing: TF-2, the newly discovered anti-cancer compound in black tea, suppresses the Cox-2 gene that triggers inflammation, says research at Rutgers. That's the same way the drugs Vioxx and Celebrex work. Also, in a UCLA study of 600 Chinese men and women, drinking green tea halved the risk of chronic stomach inflammation, which can lead to cancer.

Wipes out viruses.
Previous tests prove tea can neutralize germs, including some that cause diarrhea, pneumonia, cystitis and skin infections. Research by  Pace University finds that black and green tea deactivates viruses, including herpes.  A Japanese study showed that gargling with black tea boosted immunity to influenza. Recent at Harvard indicated that tea chemicals stimulated gamma-delta T-cells that bolster immunity against bacteria and viruses.

Burns calories
Most surprising, green tea's antioxidant EGCG stimulates the body to burn calories, notably fat. In a Swiss study, a daily dose of 270mg EGCG (the amount in 2 to 3 cups of green tea) caused men to burn 4% more energy - about 80 extra calories a day. Green tea did not increase heart rate, and the calorie burning was not due to caffeine.

Canadian researchers block cavities in mice by replacing their water with tea. Indian eye researchers have retarded cataracts in rats by feeding the animals tea extract. Israeli scientists block Parkinson's-like brain damage in mice by giving them green tea extract or pure EGCG. W

For the best benefit
Drink both black and green tea, the regular kind sold in bags or leaves in grocery stores. Their antioxidants are equal. But green tea boasts special-acting EGCG. Bottled tea and instant tea have few antioxidants, research shows.

Herbal teas do not have the same health properties as real tea (Camellia sinensis). Tea with caffeine has slightly more antioxidant activity.

Steep tea leaves or bags in hot water 3 to 5 minutes to thoroughly release antioxidants. Adding milk to tea does not block absorption of antioxidants.

General benefits of drinking tea

Antioxidants in tea: Activity and health benefits

Tea is rich in polyphenolic compounds with antioxidant properties, mainly quercetin and catechin, and these compounds may inhibit oxidative damage to DNA, lipid, carbohydrate and protein.

Tea is widely considered as a health-promoting beverage, and the beneficial effects generally associated with green tea have been attributed to its polyphenol content, particularly to catechins and their antioxidant activity.

Flavonoids exhibit anti-inflammatory properties; it was confirmed that they can also reduce blood pressure, strengthen the cell walls of blood vessels, and improve the immune system.

Its polyphenolic compounds appear to lower cholesterol levels, improve cardiovascular health and help guard against some cancers. In some studies, tea has been associated with antiallergic action and antimicrobial properties.

Moreover some epidemiological studies have associated consumption of tea with a lower risk of several types of cancer including those of the stomach, oral cavity, oesophagus and lungs.

Antioxidants are important in living organisms as well as in food because they may delay or stop formation of free radical by giving hydrogen atoms or scavenging them.

The ability to scavenge for free radicals by tea polyphenols due to possession of a phenolic hydroxyl group attached to the flavan-3-ol structure has been associated with teas’ therapeutic action against free radical mediated diseases. The mechanism of oxidation reactions is strictly dependent on the chemical structure of the compound.

Free radicals are known to contribute to numerous disorders in humans including cancer, artheroscerolosis, arthritis, ischemia, Central Nervous System (CNS) injury, gastritis, dementia, renal disorders and Acquired Immune Deficiency Syndrome (AIDS)

Processing and health benefits of Pu-erh tea

Pu-erh (pu’er) tea refers to processed leaves and buds of the broad-leaf variety of the tea plant (Camellia sinensis var. assamica (L.) O. Kuntze; Theaceae) primarily sourced from China’s Yunnan province, as well as from neighboring areas of southwestern China (Sichuan, Guangxi and Guizhou provinces), Laos, Vietnam, Myanmar, Cambodia, and northeastern India. The tea must be fermented. It is generally believed that the longer the aged Pu-erh tea is kept, the better it will be in both quality and taste. Thus, the commercial value of older Pu-erh tea is much higher than that of the younger ones.

Pu-erh tea is very popular in Asian countries, mainly in southwestern China and south Asian countries, but its consumption becomes even more popular also in Europe, due to the well-documented beneficial effects on human health.

Traditionally, pu-erh tea was valued in traditional ethnomedical systems for its ability to strengthen the immune system, improve circulation, balance the body’s hot and cold levels, detoxify blood, treat rheumatism and stones, remedy headaches, clear skin conditions, promote oral hygiene, treat stomach conditions, and reduce swelling and soft tissue.

Pu-erh tea extracts have also been reported to have lipid-lowering activity, hypoglycemic effects, protective effect against ethanol-induced gastric mucosal damages, hypouricemic effect, nitric oxide lowering effect, anti-inflammatory, anti- osteoporosis , neuroprotective and anticancer effects.

Pu-erh tea is processed from the young terminal buds and adjacent leaves of tea plants. The sun-dried green tea leaves are autoclaved and dried to make Pu-erh raw tea and stored in natural conditions to make aged Pu-erh tea, or the leaves are artificially post-fermented with microorganisms for several months to 1 year to produce ripened Pu-erh tea. For fully fermented black tea, the oxidation of the tea polyphenols is performed mainly by polyphenol oxidases from the tea leaves.

Unlike most other teas (white, green, red), which tend to lose their freshness and flavor soon after the time of production, Pu-erh, due to qualities inherent in its broad leaves, undergoes a fermentation process which improves its taste, texture and aroma over time. As such, while most teas should be consumed while they are fresh, Pu-erh tea, like fine wine, is best enjoyed many years later after the tea has been aged.

Processing and health benefits of Pu-erh tea

Skin benefits by drinking green tea

The health benefits of green tea are well documented. This antioxidant-packed drink helps fight free radicals, naturally occurring atoms that can cause disease and premature aging.

Many laboratory studies have shown that topical treatment or oral consumption of green tea polyphenols inhibits chemical carcinogen- or ultraviolet radiation-induced skin tumourigenesis in different animal models.

Green tea is effective in the area of skin care, particularly in alleviating the symptoms of acne and eczema. Topical green tea formulas have been shown to reduce sun damage by neutralizing free radicals and reducing inflammation. When used in a combination with sunscreen, green tea enhances sun protection. Due to the presence of antioxidants, green tea is also effective in slowing down the process of aging.

A study published in the October 2011 issue of the journal “Biochemical and Biophysical Research Communications” found that EGCG inhibited melanoma in laboratory animals by inhibiting genes that activate inflammation.

Treatment of green tea polyphenols to skin has been shown to modulate the biochemical pathways involved in inflammatory responses, cell proliferation and responses of chemical tumour promoters as well as ultraviolet light-induced inflammatory markers of skin inflammation.

Why white tea is good for you?

Perhaps first produced during the Tang Dynasty (618-907 AD), white tea was the preferred tea of the Chinese royal court.

White tea is so named because the silver fuzz that’s till covers the immature buds and leaves after they are picked turns white when they are dried. The leaves are steamed quickly after harvesting to prevent oxidation of polyphenols and then dried.

White tea contains high level of antioxidants because the leaves and buds are steamed and dried immediately after harvesting, locking in their antioxidant qualities. Because of this kind of processing, white tea contains far less caffeine than other types of tea.

The health benefits of white tea include:
*The polyphenols in white tea can help fight fatigue and wrinkles due to aging
*Because of its high antioxidant content, white tea can help prevent various cancers better than other types of tea by destroying free radicals
*Lower cholesterol and blood pressure. White tea contains more catechins than green tea it has better chance of lowering cholesterol
*Keep the heart and the whole of circulatory system healthy
*Stronger bones
*White tea can effectively bolster the body’s immune system
*Fluoride in white tea can help prevent tooth decay

The main reason why white tea is so much better for the body than any other type of tea is because it is the least processed type of tea.
