Olong tea is a type of tea that has been very popular since ancient times. Oolong tea has a fragrant flavor and can be mixed directly with boiling water or cooked in a tea ceremony. Nowadays, drinking oolong tea is more popular than ever because it brings great benefits to the body, as a way to burn fat, help the body lose weight and prevent obesity, for long-term use. Long term will help make the heart and blood vessels healthier, prevent and treat cardiovascular diseases.
The unique characteristic of oolong tea lies in the semi-fermentation process that creates its special color and flavor. Fermentation takes place through the tea leaves’ natural access to oxygen, activating enzymatic reactions in the tea leaves. During this period, the leaves are gradually rotated to ensure evenly distributed oxidation. When it reaches the right level, the leaves will be heated to stop the entire fermentation process.
Specifically, how long is the process of producing tea umbrellas?
Wilting
After the tea leaves are harvested, enzymes inside the leaves immediately begin chemical reactions that create the flavor and aroma of the tea. Leaves begin to wilt at this stage because moisture is lost. Tea makers can control this by controlling how much moisture the tea leaves lose in a process called wilting. Wilting will include 2 ways: wilting from sunlight (sun drying) and indoor wilting (allowing to dry naturally indoors). However, sun drying will help naturally develop the unique flavor of Oolong tea, while not destroying the natural oils and aromatics contained in the leaves.
Shaking
Is the key to making oolong tea green. After the wilted tea leaves are shaken 4 to 5 times, the leaves will undergo a series of biochemical changes, creating the unique aroma of oolong tea.
Rolling and drying
In this step, oolong tea leaves undergo a modern rolling process to take on a characteristic ball or strip shape. During the rolling and drying process, the leaves are placed in tightly tied cloth sacks. This package is then placed into a rolling mill that rolls it in a circular motion, making the leaves glossy. Then, they are put into low-temperature conveyor machines, which slowly dry the leaves.
Roasting
After the rolling and drying stages, depending on the type of tea as well as the flavor the producer wants, they will proceed with the roasting process. This is a process that requires the person to have extensive experience in roasting techniques. It is compared to “an art” that the practitioner must spend many years gaining experience. In addition, tea roasters must also consider other environmental factors such as tea tree care, harvesting time and conditions as well as the production process until the tea is dried. And finally the roasting process to achieve the best flavor for the tea.
What are the uses of oolong tea? Can I drink oolong tea every day?
Oolong tea may help reduce the risk of cardiovascular disease
A study in the Journal of the American Heart Association (JAHA) found that drinking oolong tea may help reduce the risk of cardiovascular disease.
The study analyzed the relationship between changes in high-density lipoprotein cholesterol (HDL-C) levels in the blood of more than 80,000 Chinese people and tea drinking, and was followed for 6 years.
Results showed that long-term tea drinkers had slower HDL-C levels and an 8% lower risk of cardiovascular disease. HDL-C is “good cholesterol” as opposed to “bad cholesterol” LDL-C. LDL-C is easily deposited on blood vessel walls and causes atherosclerosis, while HDL-C is the opposite and has a protective effect on blood vessels.
In fact, this is the function of polyphenols in oolong tea. Polyphenols in tea are a kind of preservative, which can be anti-oxidant and anti-inflammatory. It can also change blood viscosity, lower blood lipids, and make blood vessels more elastic.
Oolong tea is more effective in reducing the risk of cardiovascular and cerebrovascular diseases in men. Elderly people who consistently drink tea can indeed reduce the risk of death from cardiovascular disease by a percentage. big.
To prevent cardiovascular and cerebrovascular diseases, you should drink at least 3 to 4 cups a day, each cup is from 220ml to 230ml, at least 4 to 5 times a week. Don’t be greedy but drink a small amount every day.
Note: Drinking tea cannot replace the effects of medicine, but is only a way to help our body become healthier. If you have cardiovascular or cerebrovascular diseases, you still need to go to the hospital to be treated by a specialist. treat.
Improve hearing
Oolong tea has beautifying, detoxifying, convenient effects, has antioxidant effects, and eliminates reactive oxygen molecules in cells. Middle-aged and elderly people often drink oolong tea to help maintain hearing. The hearing protection effect is significantly greater in men than in women. Although drinking oolong tea has the effect of improving hearing, you should not drink too much. The appropriate amount of tea to drink per day is 1 to 2 cups.
Weight loss effect
Oolong tea has the effect of losing weight, melting fat, burning fat. Because tannic acid, the main ingredient in tea, is closely related to fat metabolism. Oolong tea can reduce blood cholesterol levels. Compared with black tea and green tea, oolong tea can not only stimulate the activity of pancreatic fat-degrading enzymes and reduce the absorption of sugar and fatty foods, but also accelerate the body’s thermogenesis. , promoting fat burning and reducing belly fat accumulation.
Lowering blood lipids
Oolong tea can prevent and reduce blood lipids in aortic atherosclerosis. Drinking oolong tea can also reduce blood viscosity, prevent red blood cells from aggregating, improve blood clotting ability, increase blood fluidity and improve microcirculation.
Lowers blood pressure
A 2004 study noted that drinking oolong tea may help lower blood pressure. People who drink one cup of tea a day are 45% more likely to reduce their blood pressure than others, and if they drink two cups, this can increase to 65%. Various studies show that oolong tea can boost metabolism and fat burning, while also improving the absorption of dietary fat. It contains calorie-burning polyphenol catechins which, when combined with exercise and a balanced diet, can promote weight loss.
